Safe Operating Practices

The following instructions are adapted from the ISO standard 5395:2013, and ANSI B71.4-2012.

Training

  • Read the Operator’s Manual and other training material carefully. Be familiar with the controls, safety signs, and the proper use of the equipment.

  • If the operator or mechanic can not read the language of this manual, it is the owner’s responsibility to explain this material to them.

  • Never allow children or people unfamiliar with these instructions to use or service the mower. Local regulations may restrict the age of the operator.

  • Never mow while people, especially children, or pets are nearby.

  • Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people or their property.

  • Do not carry passengers.

  • All drivers and mechanics should seek and obtain professional and practical instruction. The owner is responsible for training the users. Such instruction should emphasize the following:

    • The need for care and concentration when working with ride-on machines

    • Control of a ride-on machine sliding on a slope will not be regained by the application of the brake. The main reasons for loss of control are as follows:

      • Insufficient wheel grip

      • Being driven too fast

      • Inadequate braking

      • The type of machine is unsuitable for the task

      • Lack of awareness of the effect of ground conditions, especially slopes

      • Incorrect hitching and load distribution

Preparation

  • While mowing, always wear substantial footwear, long trousers, hard hat, safety glasses, and hearing protection. Long hair, loose clothing, or jewelry may get tangled in moving parts. Do not operate the equipment when barefoot or wearing open sandals.

  • Thoroughly inspect the area where the equipment is to be used and remove all objects which may be thrown by the machine.

  • Replace faulty silencers/mufflers.

  • Before using, always visually inspect to see that the blades, blade bolts, and cutting assembly are not worn or damaged. Replace worn or damaged blades and bolts in sets to preserve balance.

  • On multi-bladed machines, take care as rotating one blade can cause other blades to rotate.

  • Evaluate the terrain to determine what accessories and attachments are needed to properly and safely perform the job. Only use accessories and attachments approved by the manufacturer.

  • Check that operator’s presence controls, safety switches and shields are attached and functioning properly. Do not operate unless they are functioning properly.

Safe Handling of Fuels

  • To avoid personal injury or property damage, use extreme care in handling gasoline. Gasoline is extremely flammable and the vapors are explosive.

  • Extinguish all cigarettes, cigars, pipes, and other sources of ignition.

  • Use only an approved fuel container.

  • Never remove fuel cap or add fuel with the engine running.

  • Allow engine to cool before refueling.

  • Never refuel the machine indoors.

Toro Mower Safety

The following list contains safety information specific to Toro products or other safety information that you must know that is not included in the CEN, ISO, or ANSI standards.

This product is capable of amputating hands and feet and throwing objects. Always follow all safety instructions to avoid serious injury or death.

Use of this product for purposes other than its intended use could prove dangerous to user and bystanders.

Warning

Engine exhaust contains carbon monoxide, which is an odorless, deadly poison that can kill you. Do not run engine indoors or in an enclosed area.

Preparation

Be sure to establish your own special procedures and work rules for unusual operating conditions (e.g., slopes too steep for operation). Survey the complete mowing site to determine which hills can be safely operated on. When performing this site survey, always use common sense and take into consideration the turf condition and the rollover risk. To determine which hills or slopes may be safely operated on, use the inclinometer provided with each machine. To perform a site survey, follow the procedure outlined in the Operation section of the this manual. The maximum side hill angle is detailed on the slope decal affixed near the angle indicator.

Training

The operator must be skilled and trained in how to drive on hillsides. Failure to use caution on slopes or hills may cause the vehicle to tip or roll, possibly resulting in personal injury or death.

Operation

  • Know how to stop the machine and engine quickly.

  • Do not operate the machine while wearing tennis shoes or sneakers.

  • Wearing safety shoes and long pants is advisable and required by some local ordinances and insurance regulations.

  • Keep hands, feet, and clothing away from moving parts and the mower discharge area.

  • Fill the fuel tank until level is 12 mm (1/2 inch) below the bottom of the filler neck. Do not overfill.

  • Check the safety interlock switches daily for proper operation. If a switch should fail, replace the switch before operating the machine.

  • When starting the engine, engage the parking brake, put the traction pedal in neutral, and disengage the blade drive. After the engine starts, release the parking brake and keep your foot off of the traction pedal. The machine must not move. If movement is evident, refer to the Maintenance section of this manual to adjust the traction drive.

  • Use extreme caution when operating close to sand traps, ditches, creeks, steep hillsides, or other hazards.

  • Reduce speed when making sharp turns.

  • Do not turn on hills.

  • Do not operate on a side hill that is too steep. A rollover may occur before losing traction.

  • On models 30839, 30843 and 30807, the slope angle at which the machines will tip is dependent on many factors. Among these are mowing conditions such as wet or undulating terrain, speed (especially in turns), position of the cutting units (with the Sidewinder), tire pressure, and operator experience. At side hill angles of 20 degrees or less, the risk of a rollover is low. As the slope angle increases to a recommended maximum limit of 25 degrees, the risk of a rollover increases to a moderate level. Do not exceed a 25 degree side hill slope angle because the risk of a rollover and serious injury or death is very high.

  • On model 30849, the slope angle at which the machine will tip is dependent on many factors. Among these are mowing conditions such as wet or undulating terrain, speed (especially in turns), position of the cutting units (with the Sidewinder), tire pressure, and operator experience. At side hill angles of 15 degrees or less, the risk of a rollover is low. As the slope angle increases to a recommended maximum limit of 20 degrees, the risk of a rollover increases to a moderate level. Do not exceed a 20 degree side hill slope angle because the risk of a rollover and serious injury or death is very high.

  • For steering control, lower the cutting units when going down slopes.

  • Avoid sudden stops and starts.

  • Use the reverse pedal for braking.

  • Watch for traffic when near or crossing roads. Always yield the right-of-way.

  • Raise the cutting units when driving from one work area to another.

  • Do not touch the engine, muffler, exhaust pipe, or hydraulic tank while the engine is running or soon after it has stopped because these areas could be hot enough to cause burns.

  • This machine is not designed or equipped for on-road use and is a slow-moving vehicle. If you must cross or travel on a public road, you should be aware of and comply with local regulations, such as required lights, slow moving vehicle signs, and reflectors.

Maintenance and Storage

  • Before servicing or making adjustments, stop the engine and remove the ignition key.

  • Ensure that the entire machine is properly maintained and in good operating condition. Frequently check all nuts, bolts, screws, and hydraulic fittings.

  • Make sure all hydraulic line connectors are tight and all hydraulic hoses and lines are in good condition before applying pressure to the system.

  • Keep your body and hands away from pin hole leaks or nozzles that eject hydraulic fluid under high pressure. Use paper or cardboard, not your hands, to search for leaks. Hydraulic fluid escaping under pressure can have sufficient force to penetrate the skin and cause serious injury. If fluid is injected into the skin it must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result.

  • Before disconnecting or performing any work on the hydraulic system, all pressure in the system must be relieved by stopping the engine and lowering the cutting units to the ground.

  • If the engine must be running to perform a maintenance adjustment, keep hands, feet, clothing, and any parts of the body away from the cutting units, attachments, and any moving parts. Keep everyone away.

  • Do not overspeed the engine by changing governor settings. To ensure safety and accuracy, have an Authorized Toro Distributor check the maximum engine speed with a tachometer.

  • The engine must be shut off before checking the oil or adding oil to the crankcase.

  • If major repairs are ever needed or if assistance is desired, contact an Authorized Toro Distributor.

  • To ensure optimum performance and continued safety certification of the machine, use only genuine Toro replacement parts and accessories. Replacement parts and accessories made by other manufacturers could be dangerous, and such use could void the product warranty.

    g008875
  2. Secure the exhaust guard to the frame with 4 self-tapping screws (Figure 10).

Adjusting the Lift Arms

  1. Start the engine, raise the cutting units, and check to ensure that the clearance between each lift arm and the floor plate bracket is 5 to 8 mm (0.18 to 0.32 inches) (Figure 11).

    g008876

    If the clearance is not in this range, adjust it as follows:

    1. Back off the stop bolts (Figure 12).

      g008877
    2. Back off the jam nut on the cylinder (Figure 13).

      g008878
    3. Remove the pin from the rod end and rotate the clevis.

    4. Install the pin and check the clearance. Repeat the procedure if required.

    5. Tighten the clevis jam nut.

  2. Check to make sure that the clearance between each lift arm and stop bolt is 0.13 to 1.02 mm (0.005 to 0.040 inches) (Figure 12). If the clearance is not in this range, adjust the stop bolts to attain clearance.

  3. Start the engine, raise the cutting units, and check to make sure that the clearance between the wear strap on the top of the rear cutting unit wear bar and the bumper strap is 0.51 to 2.54 mm (0.02 to 0.10 inches) (Figure 14).

    g008879

    If the clearance is not in this range, adjust the rear cylinder as follows:

    Note: If the rear lift arm clunks during transport, clearance can be reduced.

    1. Lower the cutting units and back off the jam nut on the cylinder (Figure 15).

      g008880
    2. Grasp the cylinder rod close to the nut with a pliers and rag and rotate the rod.

    3. Raise the cutting units and check the clearance. Repeat the procedure if required.

    4. Tighten the clevis jam nut.

Important: Lack of clearance at the front stops or rear wear bar could damage the lift arms.

Rear Ballast

Models 30843, 30839 and 30807 conform to CEN standard EN 836:1997 and ANSI standard B71.4-2004 standard when 22.6 kg (50 lbs) of calcium chloride ballast is added to the rear wheels. Model 30849 conforms to CEN standard EN 836:1997 and ANSI standard B71.4-2004 standard when 30 kg. (67 lbs) of calcium chloride ballast is added to the rear wheel and weight, part no. 104-3965 is added to the rear fork.

Important: If a puncture occurs in a tire with calcium chloride, remove the machine from the turf as quickly as possible. To prevent possible damage to the turf, immediately soak the affected area with water.

Adjusting the Carrier Frame

Adjusting the Front Cutting Decks

The front and rear cutting decks require different mounting positions. The front cutting deck has two mounting positions depending on what height-of-cut and degree of deck rotation you desire.

  1. For heights of cut in the 2 to 7.6 cm (3/4 to 3 inch) range, mount the front carrier frames in the lower front mounting holes (Figure 16).

    Note: This permits more up travel of the cutting decks relative to tractor when approaching quick uphill changes in terrain. It does however limit the clearance of the chamber to the carrier when cresting sharp knolls.

    g011343
  2. For heights of cut in the 6.3 to 10 cm (2-1/2 to 4 inch) range, mount the front carrier frames in the upper front mounting holes (Figure 16).

    Note: This increases the chamber to carrier clearance due to the higher position of the cutting chamber, but will cause the cutting deck to reach their maximum up travel sooner.

Adjusting the Rear Cutting Deck

The front and rear cutting decks require different mounting positions. The rear cutting deck has one mounting position for proper alignment with the sidewinder under frame.

For all heights of cut, mount the rear cutting deck in the rear mounting holes (Figure 16).

Adjusting the Height-of-Cut

Important: This cutting deck often cuts approximately 6 mm (1/4 inch) lower than a reel cutting unit with the same bench setting. It may be necessary to have these rotary cutting deck’s bench set 6 mm (1/4 inch) above that of reels cutting in the same area.

Important: Access to the rear cutting units is greatly improved by removing the cutting unit from the tractor. If the unit is equipped with a Sidewinder®, sidewind the cutting units to the right, remove the rear cutting unit, and slide it out to the right side.

  1. Lower the cutting deck to the ground, stop the engine, and remove the key from ignition switch.

  2. Loosen the bolt securing each height-of-cut bracket to the height-of-cut plate (front and each side) (Figure 17).

  3. Beginning with front adjustment, remove the bolt.

    g011344
  4. While supporting the chamber, remove the spacer (Figure 17).

  5. Move the chamber to the desired height-of-cut and install a spacer into the designated height-of-cut hole and slot (Figure 18).

    g026184
  6. Position the tapped plate in line with the spacer.

  7. Install the bolt finger tight.

  8. Repeat steps 4-7 for each side adjustment.

  9. Tighten all three bolts to 41 N-m (30 ft-lb). Always tighten the front bolt first.

    Note: Adjustments of more than 3.8 cm (1-1/2 inches) may require temporary assembly to an intermediate height to prevent binding (e.g. changing from 3.1 to 7 cm (1.25 to 2.75 inch) height-of-cut).

Adjusting the Roller Scraper (Optional)

The optional rear roller scraper is designed to work best when there is an even gap of 0.5 to 1 mm (0.020–0.040 inch) between the scraper and roller.

  1. Loosen the grease fitting and the mounting screw (Figure 19).

    g011346
  2. Slide the scraper up or down until a gap of 0.5 to 1 mm (0.020 to 0.040 inch) is achieved between the rod and the roller.

  3. Secure the grease fitting and screw to 41 N-m (30 ft-lb) in an alternating sequence.

Installing the Mulching Baffle (Optional)

  1. Thoroughly clean debris from the mounting holes on the rear wall and left side wall of the chamber.

  2. Install the mulching baffle in the rear opening and secure it with 5 flange head bolts (Figure 20).

    g011347
  3. Verify that mulching baffle does not interfere with the tip of the blade and does not protrude inside the surface of the rear chamber wall.

    Warning

    Do not use the high lift blade with the mulching baffle. The blade could break, resulting in personal injury or death.

Checking the Engine Oil Level

Maintenance Service IntervalMaintenance Procedure
Before each use or daily
  • Check the engine oil level.
  • The engine is shipped with oil in the crankcase; however, the oil level must be checked before and after the engine is first started.

    Crankcase capacity is approximately 2.8 liters (4 quarts) with the filter.

    Use high-quality engine oil that meets the following specifications:

    • API Classification Level Required: CH-4, CI-4 or higher.

    • Preferred oil: SAE 15W-40 (above 0ºF (-17ºC))

    • Alternate oil: SAE 10W-30 or 5W-30 (all temperatures)

    Note: Toro Premium Engine oil is available from your distributor in either 15W-40 or 10W-30 viscosity. See the parts catalog for part numbers.

    Note: The best time to check the engine oil is when the engine is cool before it has been started for the day. If it has already been run, allow the oil to drain back down to the sump for at least 10 minutes before checking. If the oil level is at or below the “add” mark on the dipstick, add oil to bring the oil level to the “full” mark. DO NOT OVERFILL. If the oil level is between the “full” and “add” marks, no oil addition is required.

    1. Position the machine on a level surface.

    2. Remove the dipstick (Figure 25) and wipe it with a clean rag.

      g008881
    3. Push the dipstick down into the dipstick tube and make sure that it is seated fully. Pull the dipstick out and check the oil level.

    4. If the oil level is low, remove the oil fill cap (Figure 26) and gradually add small quantities of oil, checking the level frequently, until the level reaches the Full mark on the dipstick.

      g008882
    5. Install the oil fill cap and close the hood.

    Filling the Fuel Tank

    Use only clean, fresh diesel fuel or biodiesel fuels with low (<500 ppm) or ultra low (<15 ppm) sulfur content. The minimum cetane rating should be 40. Purchase fuel in quantities that can be used within 180 days to ensure fuel freshness.

    The fuel tank capacity is approximately 42 liters (11 gallons).

    Use summer grade diesel fuel (No. 2–D) at temperatures above 20 degrees F (–7 degrees C) and winter grade (No. 1-D or No. 1-D/2-D blend) below that temperature. Use of winter grade fuel at lower temperatures provides lower flash point and cold flow characteristics which will ease starting and reduce fuel filter plugging.

    Use of summer grade fuel above 20 degrees F (-7 degrees C) will contribute toward longer fuel pump life and increased power compared to winter grade fuel.

    Biodiesel Ready

    This machine can also use a biodiesel blended fuel of up to B20 (20% biodiesel, 80% petrodiesel). The petrodiesel portion should be low or ultra low sulfur. Observe the following precautions:

    • The biodiesel portion of the fuel must meet specification ASTM D6751 or EN14214.

    • The blended fuel composition should meet ASTM D975 or EN590.

    • Painted surfaces may be damaged by biodiesel blends.

    • Use B5 (biodiesel content of 5%) or lesser blends in cold weather

    • Monitor seals, hoses, gaskets in contact with fuel as they may be degraded over time.

    • Fuel filter plugging may be expected for a time after converting to biodiesel blends.

    • Contact your distributor if you wish for more information on biodiesel

    1. Clean the area around the fuel tank cap (Figure 27).

    2. Remove the fuel tank cap.

    3. Fill the tank to the bottom of the filler neck. Do not overfill. Install the cap.

    4. To prevent a fire hazard, wipe up any fuel that may have spilled.

      g008884

      Danger

      Under certain conditions, diesel fuel and fuel vapors are highly flammable and explosive. A fire or explosion from fuel can burn you and others and can cause property damage.

      • Use a funnel and fill the fuel tank outdoors, in an open area, when the engine is off and is cold. Wipe up any fuel that spills.

      • Do not fill the fuel tank completely full. Add fuel to the fuel tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck. This empty space in the tank allows the fuel to expand.

      • Never smoke when handling fuel, and stay away from an open flame or where fuel fumes may be ignited by a spark.

      • Store fuel in a clean, safety-approved container and keep the cap in place.

    Checking the Cooling System

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the engine coolant level.
  • Clean debris off of the radiator and oil cooler daily (Figure 28). Clean the radiator hourly if conditions are extremely dusty and dirty; refer to Cleaning the Engine Cooling System.

    g008883

    The cooling system is filled with a 50/50 solution of water and permanent ethylene glycol anti-freeze. Check the coolant level at the beginning of each day before starting the engine.

    The capacity of the cooling system is approximately 5.7 liters (6 quarts).

    Caution

    If the engine has been running, the pressurized, hot coolant can escape and cause burns.

    • Do not open the radiator cap when the engine is running.

    • Use a rag when opening the radiator cap, and open the cap slowly to allow steam to escape.

    1. Check the coolant level in the expansion tank (Figure 29). With a cold engine, the coolant level should be approximately midway between the marks on the side of the tank.

    2. If the coolant level is low, remove the expansion tank cap and replenish the system. Do not overfill.

    3. Install the expansion tank cap.

      g008885

    Checking the Hydraulic System

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the hydraulic fluid level.
  • The machines reservoir is filled at the factory with approximately 13.2 liters (3.5 U.S. gallons) of high quality hydraulic fluid. Check the level of the hydraulic fluid before the engine is first started and daily thereafter. The recommended replacement fluid is Toro Premium All Season Hydraulic Fluid (Available in 19 liter (5 gallon) pails or 55 gallon drums. See parts catalog or Toro distributor for part numbers.)

    Alternate fluids: If the Toro fluid is not available, other fluids may be used provided they meet all the following material properties and industry specifications. Toro does not recommend the use of synthetic fluid. Consult with your lubricant distributor to identify a satisfactory product Note: Toro will not assume responsibility for damage caused by improper substitutions, so use only products from reputable manufacturers who will stand behind their recommendation.

    High Viscosity Index/Low Pour Point Anti-wear Hydraulic Fluid, ISO VG 46
     Material Properties:
      Viscosity, ASTM D445cSt @ 40°C 44 to 48cSt @ 100°C 7.9 to 8.5
      Viscosity Index ASTM D2270140 to 160
      Pour Point, ASTM D97-34°F to -49°F
     Industry Specifications:
      Vickers I-286-S (Quality Level), Vickers M-2950-S (Quality Level), Denison HF-0

    Important: The ISO VG 46 Multigrade fluid has been found to offer optimal performance in a wide range of temperature conditions. For operation in consistently high ambient temperatures, 65° F (18° C) to 120° F (49° C), ISO VG 68 hydraulic fluid may offer improved performance.

    Premium Biodegradable Hydraulic Fluid-Mobil EAL EnviroSyn 46H

    Important: Mobil EAL EnviroSyn 46H is the only synthetic biodegradable fluid approved by Toro. This fluid is compatible with the elastomers used in Toro hydraulic systems and is suitable for a wide-range of temperature conditions. This fluid is compatible with conventional mineral oils, but for maximum biodegradability and performance the hydraulic system should be thoroughly flushed of conventional fluid. The oil is available in 19 liters (5 gallon) containers or 55 gallon drums from your Mobil Distributor.

    Important: Many hydraulic fluids are almost colorless, making it difficult to spot leaks. A red dye additive for the hydraulic system oil is available in 20 ml (2/3 oz.) bottles. One bottle is sufficient for 15-22 1iters (4-6 U.S. gallons) of hydraulic oil. Order part no. 44-2500 from your authorized Toro distributor.

    1. Position the machine on a level surface, lower the cutting units, and stop the engine.

    2. Clean the area around the filler neck and cap of the hydraulic tank (Figure 30). Remove the cap.

      g008886
    3. Remove the dipstick from the filler neck and wipe it with a clean rag. Insert the dipstick into the filler neck; then remove it and check the fluid level. The fluid level should be within 6 mm (1/4 inch) of the mark on the dipstick.

    4. If the level is low, add the appropriate fluid to raise the level to the full mark.

    5. Install the dipstick and cap onto the filler neck.

    Checking the Tire Pressure

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the tire pressure.
  • The tires are over-inflated for shipping. Therefore, release some of the air to reduce the pressure. The correct air pressure in the tires is 97 to 124 kPa (14 to 18 psi).

    Note: Maintain the recommended pressure in all tires to ensure a good quality of cut and proper machine performance.

    Danger

    Low tire pressure decreases machine side hill stability. This could cause a rollover, which may result in personal injury or death.

    Do not under-inflate the tires.

    Torquing the Wheel Nuts

    Maintenance Service IntervalMaintenance Procedure
    After the first hour
  • Torque the wheel nuts.
  • After the first 10 hours
  • Torque the wheel nuts.
  • Every 200 hours
  • Torque the wheel nuts.
  • Torque the wheel nuts to 61 to 88 N-m (45 to 65 ft-lb).

    Warning

    Failure to maintain proper torque of the wheel nuts could result in personal injury.

    Starting and Stopping the Engine

    You may need to bleed the fuel system if any of the following situations have occurred (refer to Bleeding the Fuel System):

    • Initial start up of a new engine

    • The engine has ceased running due to lack of fuel.

    • Maintenance has been performed upon the fuel system components; i.e. filter replaced, etc.

    Starting the Engine

    1. Be sure that the parking brake is set and the cutting unit drive switch is in the Disengage position.

    2. Remove your foot from the traction pedal and make sure that the pedal is in the neutral position.

    3. Move the throttle lever to the 1/2 throttle position.

    4. Insert the key into the switch and rotate it to the On/Preheat position until the glow plug indicator light goes out (approximately 7 seconds); then rotate the key to the Start position to engage the starter motor. Release the key when the engine starts. The key will move automatically to the On/Run position.

      Important: To prevent overheating of the starter motor, do not engage the starter longer than 15 seconds. After 10 seconds of continuous cranking, wait 60 seconds before engaging the starter motor again.

    5. When the engine is started for the first time or after an overhaul of the engine, operate the machine in forward and reverse for one to two minutes. Also operate the lift lever and cutting unit drive switch to be sure of proper operation of all parts.

      Turn the steering wheel to the left and right to check steering response; then shut the engine off and check for oil leaks, loose parts, and any other noticeable malfunctions.

      Caution

    3. While sitting on the seat, put the traction pedal in neutral, the parking brake off, and the cutting unit switch in the Off position. The engine should start. Rise from the seat and slowly press the traction pedal, the engine should stop in one to three seconds. Correct problem if it is not operating properly.

    Note: The machine is equipped with an interlock switch on the parking brake. The engine will stop if the traction pedal is pressed with the parking brake engaged.

    Towing the Traction Unit

    In case of an emergency, the machine can be towed for a short distance; however, Toro does not recommend this as a standard procedure.

    Important: Do not tow the machine faster than 3 to 4 km/h (2 to 3 MPH) because the drive system may become damaged. If the machine must be moved a considerable distance, transport it on a truck or trailer.

    1. Locate the bypass valve on the pump (Figure 32) and rotate it 90°.

      g008892
    2. Before starting the engine, close the bypass valve by rotating it 90° (1/4 turn). Do not start the engine when the valve is open.

    Standard Control Module (SCM)

    The Standard Control Module is a potted electronic device produced in a one size fits all configuration. The module uses solid state and mechanical components to monitor and control standard electrical features required for safe product operation.

    The module monitors inputs including neutral, parking brake, PTO, start, backlap, and high temperature. The module energizes outputs including PTO, Starter, and ETR (energize to run) solenoid.

    The module is divided into inputs and outputs. Inputs and outputs are identified by green LED indicators mounted on the printed circuit board.

    The start circuit input is energized by 12 VDC. All other inputs are energized when the circuit is closed to ground. Each input has a LED that is illuminated when the specific circuit is energized. Use the input LED’s for switch and input circuit troubleshooting.

    Output circuits are energized by an appropriate set of input conditions. The three outputs include PTO, ETR, and START. Output LED’s monitor relay condition indicating the presence of voltage at one of three specific output terminals.

    Output circuits do not determine output device integrity so electrical troubleshooting includes output LED inspection and conventional device and wire harness integrity testing. Measure disconnected component impedance, impedance through wire harness (disconnect at SCM), or by temporarily ”test energizing” the specific component.

    The SCM does not connect to an external computer or hand held device, can not be re–programmed, and does not record intermittent fault troubleshooting data.

    The decal on the SCM only includes symbols. Three LED output symbols are shown in the output box. All other LED’s are inputs. The chart below identifies the symbols.

    g008893

    Here are the logical troubleshooting steps for the SCM device.

    1. Determine the output fault you are trying to resolve (PTO, START, or ETR).

    2. Move key switch to the On position and ensure that the red power LED is illuminated.

    3. Move all input switches to ensure all LED’s change state.

    4. Position input devices at appropriate position to achieve the appropriate output. Use the following logic chart to determine the appropriate input condition.

    5. If specific output LED is illuminated without appropriate output function, check output harness, connections, and component. Repair as required.

    6. If specific output LED is not illuminated, check both fuses.

    7. If specific output LED is not illuminated and inputs are in appropriate condition, install new SCM and determine if fault disappears.

    Each row (across) in the logic chart below identifies input and output requirements for each specific product function. Product functions are listed in the left column. Symbols identify specific circuit condition including: energized to voltage, closed to ground, and open to ground.

    • (+) Indicates an energized circuit (clutch coil, solenoid, or start input) LED ON.

    • A Blank indicates a circuit that is not involved with the logic.

    To troubleshoot, turn on the key without starting the engine. Identify the specific function that does not work and work across the logic chart. Inspect the condition of each input LED’s to ensure it matches the logic chart.

    If the input LED’s are correct, check the output LED. If the output LED is illuminated but the device is not energized, measure available voltage at the output device, continuity of the disconnected device, and potential voltage on the ground circuit (floating ground). Repairs will vary depending on your findings.

    Selecting a Blade

    Standard Combination Sail

    This blade was designed to provide excellent lift and dispersion in almost any condition. If more or less lift and discharge velocity is required, consider a different blade.

    Attributes: Excellent lift and dispersion in most conditions.

    Angled Sail

    The blade generally performs best in lower heights of cut - 1.9 to 6.4 cm (3/4 to 2–1/2 inch).

    Attributes:

    • Discharge remains more even at lower heights of cut.

    • Discharge has less tendency to throw left and thus a cleaner look around bunkers and fairways.

    • Lower power requirement at lower heights and dense turf.

    High Lift Parallel Sail

    The blade generally performs better in the higher heights of cut - 7 to 10 cm (2 to 4 inch).

    Attributes:

    • More lift and higher discharge velocity.

    • Sparse or limp turf is picked up significantly at higher heights of cut.

    • Wet or sticky clippings are discharged more efficiently reducing congestion in the deck.

    • Requires more horsepower to run.

    • Tends to discharge further left and can tend to windrow at lower heights of cut.

    Warning

    Do not use the high lift blade with the mulching baffle. The blade could break, resulting in personal injury or death.

    Operating Tips

    General Tips for Models 30839, 30843 and 30807

    Danger

    The mower has a unique traction system that will allow the machine to move forward on side hills, even if the uphill wheel should come off of the ground. If this should happen, the operator or any bystanders can be seriously injured or killed in a rollover.

    The slope angle at which the machine will tip is dependent on many factors. Among these are: mowing conditions such as wet of undulating turf, speed (especially in turns), position of the cutting units (with Sidewinder), tire pressure, and operator experience.

    At side hill angles of 20 degrees or less, the risk of a rollover is low. As the slope angle increases to a recommended maximum limit of 25 degrees, the risk of a rollover increases to a moderate level. Do not exceed a 25 degree side hill slope angle because the risk of a rollover and serious injury or death is very high.

    To determine which hills or slopes you may safely operate on, a site survey of the mowing area must be done. When performing this site survey, always use common sense and take into consideration the turf condition and the rollover risk. To determine which hills or slopes may be safely operated on, use the inclinometer provided with each machine. To perform a site survey, lay a 4 ft 2x4 (1.25 meter plank) on the slope surface and measure the angle of the slope. The 2x4 will average the slope but will not take into consideration dips or holes which can cause a sudden change in side hill angle. The maximum side hill angle should not be greater than 25 degrees.

    Additionally, the machine is equipped with an angle indicator mounted on the steering tube. This indicates the side hill angle the machine is on and identifies the recommended maximum limit of 25 degrees.

    Always wear your seat belt.

    • Practice operating the machine and become thoroughly familiar with it.

    • Start the engine and run it at half idle until it warms up. Push the throttle lever all the way forward, lift the cutting units, disengage the parking brake, press the forward traction pedal, and carefully drive to an open area.

    • Practice moving forward and reverse, and starting and stopping the machine. To stop, take your foot off of the traction pedal and let it return to neutral or press down on the reverse pedal to stop. Going down a hill, you may need to use the reverse pedal to stop.

    • When driving on slopes, drive slowly to maintain steering control and avoid turns to prevent rollovers. In side hill situations you should shift the sidewinder cutting units to the uphill side to give you more stability. Conversely, shifting the cutting units to the down hill side will give you less stability. This should always be done before going on a side hill.

    • When possible, mow up and down hills rather than across them. Have the cutting units lowered when going down a hill to maintain steering control. Do not attempt to turn on a hill.

    • Practice driving around obstacles with the cutting units up and down. Be careful when driving between narrow objects so you do not damage the machine or cutting units.

    • On the Sidewinder unit, get a feel for the reach of the cutting units so you do not hang them up or damage them in any way.

    • Do not shift the units from side to side, unless the cutting units are down and the machine is moving, or the cutting units are up in the transport position. Shifting the cutting units when they are down and the machine is not moving may cause turf damage.

    • Always drive slowly in rough areas.

    • If a person appears in or near the operating area, stop the machine, and do not start it again until the area is cleared. The machine is designed for one person. Never let anyone else ride on the machine with you. This is extremely dangerous and could result in serious injury.

    • Accidents can happen to anyone. The most common causes are excessive speed, sudden turns, terrain (not knowing which slopes and hills can be mowed safely), not stopping the engine before leaving the operator’s seat, and drugs which impair your alertness. Cold capsules or prescription drugs may cause drowsiness, as can alcohol and other drugs. Stay alert and stay safe. Failure to do so could result in serious injury.

    • The Sidewinder offers up to a maximum of 33 cm (13 inches) of overhang, allowing you to trim closer to the edge of sand traps and other obstacles, while at the same time keeping the tractor tires as far away from the edge of traps or water hazards as possible.

    • If an obstacle is in the way, shift the cutting units to easily mow around it.

    • When transporting the machine from one work area to another, raise the cutting units to the fully up position, move the mow/transport slide to the left to transport, and place the throttle in the Fast position.

    Mowing Patterns

    Change mowing patterns often to minimize aftercut appearance issues induced by repetitive operation in only one direction.

    Counterbalance

    The counterbalance system maintains hydraulic back pressure on the deck lift cylinders. This counterbalance pressure transfers cutting deck weight to the mower's drive wheels to improve traction. The counterbalance pressure has been factory set to an optimal balance of aftercut appearance and traction capability in most turf conditions. Decreasing the counterbalance setting can produce a more stable cutting deck, but can decrease the traction capability. Increasing the counterbalance setting can increase the traction capability, but may result in aftercut appearance issues. Reference the service manual for your traction unit for instructions to adjust counterbalance pressure.

    General Tips for Model 30849

    Danger

    The slope angle at which the machine will tip is dependent on many factors. Among these are: mowing conditions such as wet of undulating turf, speed (especially in turns), tire pressure, and operator experience.

    At side hill angles of 15 degrees or less, the risk of a rollover is low. As the slope angle increases to a recommended maximum limit of 20 degrees, the risk of a rollover increases to a moderate level. Do not exceed a 20 degree side hill slope angle because the risk of a rollover and serious injury or death is very high.

    To determine which hills or slopes you may safely operate on, a site survey of the mowing area must be done. When performing this site survey, always use common sense and take into consideration the turf condition and the rollover risk. To determine which hills or slopes may be safely operated on, use the inclinometer provided with each machine. To perform a site survey, lay a 4 ft 2x4 (1.25 meter plank) on the slope surface and measure the angle of the slope. The 2x4 will average the slope but will not take into consideration dips or holes which can cause a sudden change in side hill angle. The maximum side hill angle should not be greater than 20 degrees.

    Always wear your seat belt.

    • Practice operating the machine and become thoroughly familiar with it.

    • Start the engine and run it at half idle until it warms up. Push the throttle lever all the way forward, lift the cutting units, disengage the parking brake, press the forward traction pedal, and carefully drive to an open area.

    • Practice moving forward and reverse, and starting and stopping the machine. To stop, take your foot off of the traction pedal and let it return to neutral or press down on the reverse pedal to stop. Going down a hill, you may need to use the reverse pedal to stop.

    • When driving on slopes, drive slowly to maintain steering control and avoid turns to prevent rollovers.

    • When possible, mow up and down hills rather than across them. Have the cutting units lowered when going down a hill to maintain steering control. Do not attempt to turn on a hill.

    • Practice driving around obstacles with the cutting units up and down. Be careful when driving between narrow objects so you do not damage the machine or cutting units.

    • On the Sidewinder unit, get a feel for the reach of the cutting units so you do not hang them up or damage them in any way.

    • Do not shift the units from side to side, unless the cutting units are down and the machine is moving, or the cutting units are up in the transport position. Shifting the cutting units when they are down and the machine is not moving may cause turf damage.

    • Always drive slowly in rough areas.

    • When transporting the machine from one work area to another, raise the cutting units to the fully up position, move the mow/transport slide to the left to transport, and place the throttle in the Fast position.

    Mowing Techniques

    • To begin cutting, engage the cutting units, then approach the mowing area slowly. Once the front cutting units are over the mowing area, lower the cutting units.

    • To achieve the professional straight-line cut and striping that is desirable for some applications, find a tree or other object in the distance and drive straight toward it.

    • As soon as the front cutting units reach the edge of the mowing area, lift the cutting units and perform a tear drop shaped turn to quickly line you up for your next pass.

    • To mow around bunkers, ponds, or other contours easily, use the Sidewinder and move the control lever left or right, depending on your mowing application. The cutting units can also be shifted to vary tire tracking.

    • The cutting units tend to throw grass to the left side of the machine. If trimming around bunkers, it is best to mow in a clockwise direction to prevent throwing clippings into the bunker.

    • The cutting units can be equipped with bolt-in mulching baffles. The mulching baffles perform well when turf is maintained on a regular schedule to avoid removing more than 25 mm (1 inch) of growth per cutting. When too much growth is cut with the mulching baffles installed, after-cut appearance may deteriorate and the observed power to cut the turf increases. The mulching baffles also perform well for shredding leaves in the fall of the year.

    Mow When Grass is Dry

    Mow either in the late morning to avoid the dew, which causes grass clumping, or in late afternoon to avoid the damage that can be caused by direct sunlight on the sensitive, freshly mowed grass.

    Select the Proper Height-of-Cut Setting to Suit Conditions

    Remove approximately one inch or no more than 1/3 of the grass blade when cutting. In exceptionally lush and dense grass you may have to raise your height–of–cut setting another notch.

    Always Start Mowing with Sharp Blades

    A sharp blade cuts cleanly and without tearing or shredding the grass blades like a dull blade. Tearing and shredding causes the grass to turn brown at the edges which impairs growth and increases susceptibility to diseases. Make sure blade is in good condition and a full sail is present.

    Check Condition of cutting unit

    Make sure cutting chambers are in good condition. Straighten any bends in chamber components to assure correct blade tip/chamber clearance.

    After Mowing

    At the completion of mowing operation, thoroughly wash the machine with a garden hose without a nozzle so that excessive water pressure will not cause contamination and damage to the seals and bearings. Make sure that the radiator and oil cooler are kept free of dirt or grass clippings. After cleaning, it is recommended that the machine be inspected for possible hydraulic fluid leaks, damage or wear to the hydraulic and mechanical components, and the cutting unit blades checked for sharpness.

    Important: After washing the machine, move the Sidewinder mechanism from left to right several times to remove water between the bearing blocks and cross tube.

    Maintenance

    Note: Determine the left and right sides of the machine from the normal operating position.

    Engine Maintenance

    Servicing the Air Cleaner

    Maintenance Service IntervalMaintenance Procedure
    Every 200 hours
  • Service the Air Cleaner(More frequently in extreme dusty or dirty conditions)
    • Check the air cleaner body for damage which could cause an air leak. Replace if damaged. Check the whole intake system for leaks, damage, or loose hose clamps.

    • Service at the recommended service interval or earlier if engine performance suffers due to extremely dusty, dirty conditions. Changing the air filter before it is necessary only increases the chance of dirt entering the engine when the filter is removed.

    • Be sure the cover is seated correctly and seals with the air cleaner body.

    1. Release the latches securing the air cleaner cover to the air cleaner body (Figure 51).

      g008909
    2. Remove the cover from the air cleaner body.

    3. Before removing the filter, use low pressure air (40 psi, clean and dry) to help remove large accumulations of debris packed between outside of primary filter and the canister. Avoid using high pressure air which could force dirt through the filter into the intake tract. This cleaning process prevents debris from migrating into the intake when the primary filter is removed.

    4. Remove and replace the primary filter (Figure 52).

      Cleaning of the used element is not recommended due to the possibility of damage to the filter media.

      g008910

    3. Remove the lynch pin or retaining nut securing the deck carrier frame to the lift arm pivot pin (Figure 68).

      g011352
    4. Roll the cutting deck away from the traction unit.

    Mounting the Cutting Decks to the Traction Unit

    1. Position machine on a level surface and shut engine off.

    2. Move cutting deck into position in front of traction unit.

    3. Slide deck carrier frame onto lift arm pivot pin. Secure with lynch pin or retaining nut (Figure 68).

    4. Install the hydraulic motor to the deck (Figure 67). Make sure that the O-ring is in position and not damaged.

    5. Grease the spindle.

    Servicing the Blade Plane

    The rotary deck comes from the factory preset at 5 cm (2.00 inch) height-of-cut and blade rake of 7.9 mm ( 0.310 inch). The left-hand and right-hand heights are also preset to within ± 0.7 mm (0.030 inch) of the other.

    The cutting deck is designed to withstand blade impacts without deformation of the chamber. If a solid object is struck, inspect the blade for damage and the blade plane for accuracy.

    Inspecting the Blade Plane

    1. Remove the hydraulic motor from the cutting deck and remove the cutting deck from the tractor.

    2. Use a hoist (or minimum of two people) and place the cutting deck on a flat table

    3. Mark one end of the blade with a paint pen or marker. Use this end of the blade to check all heights.

    4. Position the cutting edge of the marked end of the blade at 12 o’clock (straight ahead in the direction of mowing) (Figure 69) and measure height from table to cutting edge of blade.

      g011353
    5. Rotate the marked end of the blade to the 3 and 9 o’clock positions (Figure 69) and measure the heights.

    6. Compare the 12 o’clock measured height to the height-of-cut setting. It should be within 0.7 mm (0.030 inch). The 3 and 9 o’clock heights should be 3.8±2.2 mm (0.150±.090 inch) higher than the 12 o’clock setting and within 2.2 mm (0.090 inch) of each other.

    If any of these measurements are not within specification, proceed to Adjusting the Blade Plane.

    Adjusting the Blade Plane

    Start with the front adjustment (change one bracket at a time).

    1. Remove the height-of-cut bracket, (front, left, or right) from the deck frame (Figure 70).

    2. Adjust 1.5 mm (0.060 inch) shims and/or 0.7 mm (0.030 inch) shim between the deck frame and bracket to achieve the desired height setting (Figure 70).

      g011354
    3. Install the height-of-cut bracket to the deck frame with the remaining shims assembled below the height-of-cut bracket.

    4. Secure the socket head bolt/spacer and flange nut.

      Note: Socket head bolt/spacer are held together with Loctite to prevent the spacer from falling inside the deck frame.

    5. Verify the 12 o’clock height and adjust if needed.

    6. Determine if only one or both (right-hand and left-hand) height-of-cut brackets need to be adjusted. If the 3 or 9 o’clock side is 3.8±2.2 mm (0.150±0.090 inch) higher than the new front height then no adjustment is needed for that side. Adjust the other side to within ±2.2 mm (0.090 inch) of the correct side.

    7. Adjust the right and/or left height-of-cut brackets by repeating steps 1 through 3.

    8. Secure the carriage bolts and flange nuts.

    9. Again, verify the 12, 3, and 9 o’clock heights.

    Servicing the Cutter Blade

    Removing the Cutter Blade

    The blade must be replaced if a solid object is hit, the blade is out of balance, or if the blade is bent. Always use genuine Toro replacement blades to be sure of safety and optimum performance. Never use replacement blades made by other manufacturers because they could be dangerous.

    1. Raise the cutting deck to the highest position, shut the engine off, and engage the parking brake. Block the cutting deck to prevent it from falling accidentally.

    2. Grasp the end of the blade using a rag or thickly padded glove. Remove the blade bolt, anti-scalp cup, and blade from the spindle shaft (Figure 71).

      g011355
    3. Install the blade, sail facing toward the cutting deck, with the anti-scalp cup and blade bolt (Figure 71). Tighten blade bolt to 115–149 N-m (85–110 ft-lb).

      Danger

      A worn or damaged blade can break, and a piece of the blade could be thrown into the operator’s or bystander’s area, resulting in serious personal injury or death

      • Inspect the blade periodically for wear or damage.

      • Never weld a broken or cracked blade.

      • Always replace a worn or damaged blade.

    Inspecting and Sharpening the Blade

    1. Raise the cutting deck to the highest position, shut the engine off, and engage the parking brake. Block the cutting deck to prevent it from falling accidentally.

    2. Examine the cutting ends of the blade carefully, especially where the flat and curved parts of the blade meet (Figure 72). Since sand and abrasive material can wear away the metal that connects the flat and curved parts of the blade, check the blade before using the machine. If wear is noticed (Figure 72), replace the blade; refer to Removing the Cutter Blade.

      Danger

      If the blade is allowed to wear, a slot will form between the sail and flat part of the blade (Figure 72). Eventually a piece of the blade may break off and be thrown from under the housing, possibly resulting in serious injury to yourself or bystanders.

      • Inspect the blade periodically for wear or damage.

      • Always replace a worn or damaged blade.

      g006924
    3. Inspect the cutting edges of all blades. Sharpen the cutting edges if they are dull or nicked. Sharpen only the top of the cutting edge and maintain the original cutting angle to make sure of sharpness (Figure 73). The blade will remain balanced if the same amount of metal is removed from both cutting edges.

      g006926
    4. To check the blade for being straight and parallel, lay the blade on a level surface and check its ends. The ends of the blade must be slightly lower than the center, and the cutting edge must be lower than the heel of the blade. This blade will produce good quality of cut and require minimal power from the engine. By contrast a blade that is higher at the ends than the center, or if cutting edge is higher than the heel, the blade is bent or warped and must be replaced.

    5. Install the blade, sail facing toward cutting deck, with the anti-scalp cup and blade bolt. Tighten the blade bolt to 115–149 N-m (85–110 ft-lb).

    Checking the Blade Stopping Time

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the blade stopping time
  • The blades of the cutting deck should come to a complete stop in approximately 5 seconds after you shut down the cutting deck engagement switch.

    Note: Make sure the decks are lowered onto a clean section of turf or hard surface to avoid thrown dust and debris.

    To verify this stopping time, have a second person stand back from the deck at least 6 m (20 feet) and watch the blades on one of the cutting decks. Have the operator shut the cutting decks down and record the time it takes for the blades to come to a complete stop. If this time is greater than 7 seconds, the braking valve needs adjustment. Call your Toro Distributor for assistance in making this adjustment.

    Servicing the Front Roller

    Inspect the front roller for wear, excess wobble, or binding. Service or replace the roller or components if any of these conditions exist.

    Disassembling the Front Roller

    1. Remove the roller mounting bolt (Figure 74).

    2. Insert a punch through the end of the roller housing and drive the opposite bearing out by alternating taps to the opposite side of inner bearing race. There should be a 1.5 mm (0.060 inch) lip of inner race exposed.

      g011356
    3. Push the second bearing out in press.

    4. Inspect the roller housing, bearings, and bearing spacer for damage (Figure 74). Replace damaged components and assemble.

    Assembling the Front Roller

    1. Press the first bearing into the roller housing (Figure 74). Press on the outer race only or equally on the inner and outer race.

    2. Insert the spacer (Figure 74).

    3. Press the second bearing into the roller housing (Figure 74) pressing equally on the inner and outer race until the inner race comes in contact with the spacer.

    4. Install the roller assembly into the deck frame.

      Important: Securing the roller assembly with a gap larger than 1.5 mm (0.060 inch) creates a side load on the bearing and can lead to premature bearing failure

    5. Verify that there is no more than a 1.5 mm (0.060 inch) gap between roller assembly and the roller mount brackets of the deck frame. If there is a gap over 1.5 mm (0.060 inch), install enough 5/8 inch diameter washers to take up the slop.

    6. Secure the mounting bolt to 108 N-m (80 ft-lb).
