Safe Operating Practices

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 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

      • 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.

      • The owner/user can prevent and is responsible for accidents or injuries occurring to people, or damage to property.

Preparation

  • While mowing, always wear substantial, slip-resistant footwear, long trousers, safety glasses, and hearing protection. Long hair, loose clothing, or jewelry may get tangled in moving parts.

  • 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.

  • 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.

Operation

  • Do not operate the engine in a confined space where dangerous carbon monoxide and other exhaust gasses can collect.

  • Mow only in daylight or in good artificial light.

  • Before attempting to start the engine, disengage all blade attachment clutches, shift into neutral, and engage the parking brake.

  • Remember there is no such thing as a safe slope. Travel on grass slopes requires particular care. To guard against overturning:

    • do not stop or start suddenly when going up or downhill;

    • machine speeds should be kept low on slopes and during tight turns;

    • stay alert for humps and hollows and other hidden hazards;

    • never mow across the face of the slope, unless the mower is designed for this purpose.

  • Stay alert for holes in the terrain and other hidden hazards.

  • Watch out for traffic when crossing or near roadways.

  • Stop the blades from rotating before crossing surfaces other than grass.

  • When using any attachments, never direct discharge of material toward bystanders nor allow anyone near the machine while in operation.

  • Never operate the machine with damaged guards, shields, or without safety protective devices in place. Be sure all interlocks are attached, adjusted properly, and functioning properly.

  • Do not change the engine governor settings or overspeed the engine. Operating the engine at excessive speed may increase the hazard of personal injury.

  • Before leaving the operator’s position:

    • stop on level ground;

    • disengage the power take-off and lower the attachments;

    • change into neutral and set the parking brake;

    • stop the engine and remove the key.

  • Disengage drive to attachments when transporting or not in use.

    • before refuelling;

    • before removing the grass catcher/catchers;

    • before making height adjustment unless adjustment can be made from the operator’s position.

    • before clearing blockages;

    • before checking, cleaning or working on the mower;

    • after striking a foreign object or if an abnormal vibration occurs. Inspect the mower for damage and make repairs before restarting and operating the equipment.

  • Reduce the throttle setting before stopping the engine and, if the engine is provided with a fuel shut-off valve, turn the fuel off at the conclusion of mowing.

  • Keep hands and feet away from the cutting units.

  • Look behind and down before backing up to be sure of a clear path.

  • Slow down and use caution when making turns and crossing roads and sidewalks. Stop the reels when not mowing.

  • Do not operate the mower under the influence of alcohol or drugs.

  • Lightning can cause severe injury or death. If lightning is seen or thunder is heard in the area, do not operate the machine; seek shelter.

  • Use care when loading or unloading the machine into a trailer or truck.

  • Use care when approaching blind corners, shrubs, trees, or other objects that may obscure vision.

Rollover Protection System (ROPS)—Use and Maintenance

  • The ROPS is an integral and effective safety device. Keep a folding ROPS in the raised and locked position and use the seat belt when operating the machine.

  • Lower a folding ROPS temporarily only when absolutely necessary. Do not wear the seat belt when folded down.

  • Be aware there is no rollover protection when a folded ROPS is in the down position.

  • Be certain that the seat belt can be released quickly in the event of an emergency.

  • Check the area to be mowed and never fold down a folding ROPS in areas where there are slopes, drop offs or water.

  • Check carefully for overhead clearances (i.e. branches, doorways, electrical wires) before driving under any objects and do not contact them.

  • Keep the ROPS in safe operating condition by periodically thoroughly inspecting for damage and keeping all mounting fasteners tight.

  • Replace a damaged ROPS. Do not repair or revise.

  • Do not remove the ROPS.

  • Any alterations to a ROPS must be approved by the manufacturer.

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.

  • Never store the machine or fuel container where there is an open flame, spark, or pilot light such as on a water heater or on other appliances.

  • Never fill containers inside a vehicle or on a truck or trailer bed with a plastic liner. Always place containers on the ground away from your vehicle before filling.

  • Remove equipment from the truck or trailer and refuel it on the ground. If this is not possible, then refuel such equipment with a portable container, rather than from a fuel dispenser nozzle.

  • Keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

  • Do not use a nozzle lock open device.

  • If fuel is spilled on clothing, change clothing immediately.

  • Never overfill fuel tank. Replace fuel cap and tighten securely.

Maintenance and Storage

  • Keep all nuts, bolts and screws tight to be sure the equipment is in safe working condition.

  • Never store the equipment with fuel in the tank inside a building where fumes may reach an open flame or spark.

  • Allow the engine to cool before storing in any enclosure.

  • To reduce the risk of fire hazard, keep the engine, silencer/muffler, battery compartment, and fuel storage area free of grass, leaves, or excessive grease.

  • Replace worn or damaged parts for safety.

  • Check the grass catcher frequently for wear or deterioration.

  • Keep all parts in good working condition and all hardware and hydraulic fittings tightened. Replace all worn or damaged parts and decals.

  • If the fuel tank has to be drained, do this outdoors.

  • Be careful during adjustment of the machine to prevent entrapment of the fingers between moving blades and fixed parts of the machine.

  • On multi-reel machines, take care as rotating one reel can cause other reels to rotate.

  • Disengage drives, lower the cutting units, set parking brake, shut off the engine and remove the key. Wait for all movement to stop before adjusting, cleaning or repairing.

  • Clean grass and debris from cutting units, drives, mufflers, and engine to help prevent fires. Clean up oil or fuel spillage.

  • Use jack stands to support components when required.

  • Carefully release pressure from components with stored energy.

  • Disconnect battery before making any repairs. Disconnect the negative terminal first and the positive last. Reconnect positive first and negative last.

  • Use care when checking the reels. Wrap the reels or wear gloves, and use caution when servicing them.

  • Keep hands and feet away from moving parts. If possible, do not make adjustments with the engine running.

  • Charge batteries in an open well ventilated area, away from spark and flames. Unplug charger before connecting or disconnecting from battery. Wear protective clothing and use insulated tools.

Hauling

  • Use care when loading or unloading the machine into a trailer or truck.

  • Use full width ramps for loading machine into trailer or truck.

  • Tie the machine down securely using straps, chains, cable, or ropes. Both front and rear straps should be directed down and outward from the machine.

  • If the engine stalls or loses headway and cannot make it to the top of a slope, do not turn the machine around. Always back slowly, straight down the slope.

  • When a person or pet appears unexpectedly in or near the mowing area, stop mowing. Careless operation, combined with terrain angles, ricochets, or improperly positioned guards can lead to thrown object injuries. Do not resume mowing until the area is cleared.

  • Never remove the ROPS (Roll Over Protection System) and always use the seat belt when operating the machine.

  • Before getting off of the seat, move the functional control lever to neutral (N), raise the cutting units and wait for the reels to stop spinning. Engage the parking brake. Shut off the engine and remove the key from the switch.

  • Whenever the machine is left unattended, make sure the cutting units are fully raised, the reels are not spinning, the key is removed from the ignition switch, and the parking brake is set.

Maintenance and Storage

  • 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.

  • 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 and attachments to the ground.

  • Check all fuel lines for tightness and wear on a regular basis. Tighten or repair them as needed.

  • 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, especially the screen at the side of the engine. Keep everyone away.

  • To ensure safety and accuracy, have an Authorized Toro Distributor check the maximum engine speed with a tachometer. Maximum governed engine speed should be 2,760 rpm.

  • 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.

Think Safety First

Please carefully read all of the safety instructions and symbols in the Safety section. Knowing this information could help you or bystanders avoid injury.

The use of protective equipment, such as but not limited to, for eyes, ears, feet, and head is recommended.

Checking the Engine Oil

Maintenance Service IntervalMaintenance Procedure
Before each use or daily
  • Check the engine oil.
  • The engine is shipped with oil in the crankcase; however, you must check the oil level before and after you start the engine for the first time.

    Crankcase capacity is approximately 3.7 L (3.9 US 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 10W–30

    • Alternate oil: SAE 15W–40

    Toro Premium Engine oil is available from your distributor in the 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.

    Important: Keep the engine-oil level between the upper and lower limits on the oil gauge. Engine failure may occur as a result of over filling or under filling the engine oil.

    1. Position the machine on a level surface.

    2. Remove the dipstick and wipe it with a clean rag (Figure 22). Push the dipstick into the tube and make sure that it is seated fully. Remove the dipstick from the tube and check the level of oil. If the oil level is low, remove the filler cap from the valve cover and slowly add enough oil to raise the level to the Full mark on the dipstick. Add the oil slowly and check the level often during this process. Do not overfill.

      Important: Make sure that the dipstick is removed while filling the engine with oil. When adding engine oil or filling oil, there must be clearance between the oil-fill device and the oil-fill hole in the valve cover as shown in Figure 21. This clearance is necessary to permit venting when filling, which prevents oil from overrunning into breather.

      g016415
      g016419
    3. Replace the dipstick.

    4. Start and run the engine at idle for 30 seconds, then shut the engine off. Wait 30 seconds, then repeat steps 2–3.

      Important: Check the level of oil every 8 operating hours or daily. Change the oil and filter initially after the first 50 hours of operation, thereafter change the oil and the filter every 150 hours. However, change the oil more frequently when the engine is operated in extremely dusty or dirty conditions.

    5. Install the filler cap and dipstick firmly in place.

    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.

    Fuel tank capacity: 22.7 L (6 US gallons)

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

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

    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, sealed, safety-approved container.

    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.

    Danger

    In certain conditions, fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property.

    • Fill the fuel tank outdoors, in an open area, when the engine 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 25 mm (1 inch) below the bottom of the filler neck. This empty space in the tank allows 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 an approved container and keep it out of the reach of children. Never buy more than a 30-day supply of fuel.

    • Always place fuel containers on the ground away from your vehicle before filling

    • Do not fill fuel containers inside a vehicle or on a truck or trailer bed because interior carpets or plastic truck bed liners may insulate the container and slow the loss of any static charge.

    • When practical, remove equipment from the truck or trailer and refuel the equipment with its wheels on the ground.

    • If this is not possible, then refuel such equipment on a truck or trailer from a portable container rather than from a fuel-dispenser nozzle.

    • If you must use a fuel dispenser nozzle, keep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.

    1. Clean around the fuel-tank cap (Figure 23).

      g005112
    2. Remove the fuel-tank cap.

    3. Fill the tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck. Do not overfill. Install the cap.

    4. Wipe up any fuel that may have spilled.

    Checking the Cooling System

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Clean debris off of the radiator screen and radiator.Clean hourly if conditions are extremely dusty and dirty.
  • The capacity of the cooling system is approximately 3.2 L (3.3 US qt). Refer to Cleaning the Radiator Screen.

    g008426

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

    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. Park the machine on a level surface.

    2. Check the coolant level (Figure 25). It should be between the lines on the reserve tank when the engine is cold.

      g016420
    3. If the coolant is low, remove the reserve tank cap and add a 50/50 mixture of water and permanent ethylene glycol antifreeze. Do not overfill.

    4. Install the reserve tank cap.

    Checking the Hydraulic Fluid Level

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the hydraulic-fluid level.
  • Recommended Hydraulic Fluid

    The machines reservoir is filled at the factory with approximately 20.8 L (5.5 US gallons) of high-quality hydraulic fluid. Check the level of the hydraulic fluid before starting the engine for the first time and daily thereafter. The recommended replacement fluid is as follows:

     Toro Premium All Season Hydraulic Fluid (Available in 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, you may use other fluids provided that they meet all the following material properties and industry specifications. Do not use synthetic fluid. Contact 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.

    Hydraulic Fluid Table

    Material Properties
    Viscosity, ASTM D445cSt at 40°C (104°F): 55 to 62
    cSt at 110°C (230°F): 9.1 to 9.8
    Viscosity index, ASTM D2270140 to 152
    Pour Point, ASTM D97-37° to -43°C (-35 to -46 F)
    Industry Standards
    API GL-4, AGCO Powerfluid 821 XL, Ford New Holland FNHA-2-C-201.00, Kubota UDT, John Deere J20C, Vickers 35VQ25 and Volvo WB-101/BM.

    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, 18° to 49°C (65° to 120°F), 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 L (5 US gallons) 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 to 22 L (4 to 6 gal) of hydraulic fluid. Order Part No. 44-2500 from your authorized Toro distributor.

    Important: Regardless of hydraulic fluid type used, any machine used for mowing fairways, verticutting or used during ambient temperatures 18° to 49°C (65° to 120°F) should have Oil Cooler Kit, Part No. 104–7701, installed.

    Checking the Hydraulic Fluid Level

    1. Position the machine on a level surface. Make sure the machine has cooled down so the oil is cold.

    2. Remove the cap from the reservoir and check the level of fluid. The fluid should be up to the bottom of the screen in the filler neck (Figure 26).

      g008428
    3. If the fluid level is low, slowly fill the reservoir with the appropriate hydraulic fluid until the level reaches the bottom of the screen. Do not overfill.

      Important: To prevent system contamination, clean the top of the hydraulic fluid containers before puncturing. Ensure the pour spout and funnel are clean.

    4. Install the reservoir cap. Wipe up any fluid that may have spilled.

      Important: Check level of hydraulic fluid before engine is first started and daily thereafter.

    Draining Water from the Fuel Filter

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Drain any water from the fuel filter.
    1. Position the machine on a level surface and stop the engine.

    2. Place a drain pan under the fuel filter (Figure 27).

    3. Open the drain plug on the bottom of the fuel filter and drain any accumulated water (Figure 27). Tighten the plug after draining.

      Note: Because the accumulated water will be mixed with diesel fuel, drain the fuel filter into a suitable container and dispose of it properly.

      g007367

    Checking the Tire Pressure

    Vary the tire pressure for the front wheels, depending upon your turf conditions, from a minimum of 55 kPa to a maximum of 83 kPa (8 to 12 psi).

    Vary the tire pressure for the rear wheel from a minimum of 55 kPa to a maximum of 103 kPa (8 to 15 psi).

    Checking the Torque of the Wheel Nuts

    Maintenance Service IntervalMaintenance Procedure
    After the first hour
  • Check the torque of the wheel nuts.
  • After the first 10 hours
  • Check the torque of the wheel nuts.
  • Every 200 hours
  • Check the torque of the wheel nuts.
  • Warning

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

    Torque the wheel nuts to 95 to 122 N-m (70 to 90 ft-lb) after 1 to 4 hours of operation and again after 10 hours of operation. Torque every 200 hours thereafter.

    Checking the Reel-to-Bedknife Contact

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the reel-to-bedknife contact.
  • Refer to Adjusting the Reel to Bedknife in the Cutting Unit Operator’s Manual.

    Breaking-In the Machine

    Refer to the engine manual supplied with the machine for oil change and maintenance procedures recommended during the break-in period.

    Only 8 hours of mowing is required to break-in the machine.

    Since the first hours of operation are critical to future dependability of the machine, monitor its functions and performance closely so that minor difficulties, which could lead to major problems, are noted and can be corrected. Inspect the machine frequently during break-in for signs of oil leakage, loose fasteners, or any other malfunction.

    To ensure optimum performance of the brake system, burnish (break-in) the brakes before using the machine. To burnish the brakes, firmly apply the brakes and drive the machine at mowing speed until the brakes are hot, as indicated by their smell. You may need to adjust the brakes after break-in; refer to Adjusting the Brakes.

    Starting and Stopping the Machine

    Note: Inspect the areas beneath the mowers to be certain they are clear of debris.

    Starting the Machine

    Important: The fuel system may have to be bled if any of the following situations have occurred:

    • Initial start up of a new engine

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

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

    Refer to Draining Water from the Fuel Filter.

    Important: Do not use ether or other types of starting fluid.

    1. Ensure that the parking brake is set, the raise/lower mow control is disengaged, and the functional control is in the NEUTRAL position.

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

    3. Move the throttle lever to SLOW position.

    4. Insert the key into the switch and rotate it to ON. Hold it in the ON position until the glow plug indicator light goes off (approximately 6 seconds).

    5. Immediately turn the ignition key to the START position. Release the key when the engine starts and allow it to move to the ON position. Move the throttle control to SLOW.

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

    6. Allow the engine to warm up for a few minutes before applying a load.

      Important: When the engine is started for the first time, or after an overhaul of the engine, operate the machine in forward and reverse for 1 to 2 minutes. Turn the steering wheel to the left and right to check the steering response. Then shut off the engine (see Stopping in Starting and Stopping the Engine) and wait for all moving parts to stop. Check for oil leaks, loose parts and any other noticeable malfunctions.

    Stopping the Machine

    1. Move the throttle control to SLOW, disengage the raise/lower mow control, and move the functional control to neutral.

    2. Rotate the starter key to OFF to shut the engine off. Remove the key from the switch to prevent accidental starting.

    3. Close the fuel-shutoff valves before storing the machine.

    Checking the Safety Interlock System

    Caution

    If the safety interlock switches are disconnected or damaged the machine could operate unexpectedly causing personal injury.

    • Do not tamper with the interlock switches.

    • Check the operation of the interlock switches daily and replace any damaged switches before operating the machine.

    The purpose of the safety interlock system is to prevent operation of the machine where there is possible injury to the operator or the machine.

    The safety interlock system prevents the engine from starting unless:

    • The traction pedal is in neutral.

    • The functional control lever is in neutral.

    The safety interlock system prevents the machine from moving unless:

    • The parking brake is off.

    • The operator is seated.

    • The functional control lever is in MOW or TRANSPORT.

    The safety interlock system prevents the reels from operating unless the functional control lever is in the MOW position.

    Perform the following system checks daily to be sure the interlock system is operating correctly:

    1. Sit on the seat, move the traction pedal to NEUTRAL, move the functional control lever to NEUTRAL, and engage the parking brake. Try to depress the traction pedal. The pedal should not depress, which means that the interlock system is operating correctly. Correct the problem if it is not operating properly.

    2. Sit on the seat, move the traction pedal to NEUTRAL, move the functional control lever to NEUTRAL, and engage the parking brake. Move the functional control lever to mow or transport and try to start the engine. The engine should not crank, which means that the interlock system is operating correctly. Correct the problem if it is not operating properly.

    3. Sit on the seat, move the traction pedal to NEUTRAL, move the functional control lever to NEUTRAL, and engage the parking brake. Start the engine and move the functional control lever to mow or transport. The engine should kill, which means that the interlock system is operating correctly. Correct the problem if it is not operating properly.

    4. Sit on the seat, move the traction pedal to NEUTRAL, move the functional control lever to NEUTRAL, and engage the parking brake. Start the engine. Release the parking brake, move the functional control lever to mow, and rise from the seat. The engine should kill, which means that the interlock system is operating correctly. Correct the problem if it is not operating properly.

    5. Sit on the seat, move the traction pedal to NEUTRAL, move the functional control lever to NEUTRAL, and engage the parking brake. Start the engine. Move the raise/lower mow control forward to lower the cutting units. The cutting units should lower but not start rotating. If they do, the interlock system is not operating correctly. Correct the problem.

    Setting the Reel Speed

    To achieve a consistent, high quality-of-cut and a uniform after cut appearance, it is important that the reel speed control (located on the manifold block under seat) be correctly set.

    Adjust the reel speed control as follows:

    1. Select the height of cut at which the cutting units are set.

    2. Choose the desired ground speed best suited for conditions.

    3. Using the appropriate graph (See Figure 28) for 5-, 8-, 11- or 14-blade cutting units, determine the proper reel speed setting.

      decal115-8156
    4. To set the reel speed, rotate the knob (Figure 29) until the indicator arrows are in line with the number designating desired setting.

      g008437

      Note: Reel speed can be increased or decreased to compensate for turf conditions.

    Preparing the Machine for Mowing

    To assist in aligning the machine for successive cutting passes, do the following to the No. 2 and No. 3 cutting unit baskets:

    1. Measure in approximately 12.7 cm (5 inches) from the outer edge of each basket.

    2. Either place a strip of white tape or paint a line onto each basket paralleling the outer edge of each basket (Figure 30).

      g005115

    Training Period

    Before mowing greens with the machine, find a clear area and practice starting and stopping, raising and lowering the cutting units, turning, etc. This training period will help you in gaining confidence in the performance of the machine.

    Preparing to Mow

    Inspect the green for debris, remove the flag from the cup, and determine the best direction to mow. Base the direction to mow on the previous mowing direction. Always mow in an alternate pattern from the previous mowing so that the grass blades will be less apt to lay down and therefore be difficult to trap between the reel blades and bedknife.

    Mowing

    1. Approach the green with the functional control lever in the middle position. Start on one edge of the green so that the ribbon procedure of cutting may be used. This holds compaction to a minimum and leaves a neat, attractive pattern on the greens.

    2. Actuate the mow pedal as the front edge of the grass baskets cross the outer edge of the green. This procedure drops the cutting units to the turf and starts the reels.

      Important: Familiarize yourself with the fact that the No. 1 cutting unit reel is delayed and therefore, you should practice to try to gain the required timing necessary to minimize the cleanup mowing operation.

    3. Overlap a minimal amount with the previous cut on return passes. To assist in maintaining a straight line across the green and keep the machine an equal distance from the edge of the previous cut, establish an imaginary sight line approximately 1.8 to 3 m (6 to 10 ft) ahead of the machine to the edge of the uncut portion of the green (Figure 30 and Figure 31). Some find it useful to include the outer edge of the steering wheel as part of the sight line; i.e. keep the steering wheel edge aligned with a point that is always kept the same distance away from the front of the machine (Figure 30 and Figure 31).

      g005116
    4. As the front of the baskets cross the edge of the green, depress the lift pedal. This will stop the reels and lift the cutting units. Timing of this procedure is important, so the mowers do not cut into the fringe area. However, as much of the green as possible should be cut to minimize the amount of grass left to mow around the outer periphery

    5. Cut down on operating time and ease lineup for the next pass by momentarily turning the machine in the opposite direction, then turning in the direction of the uncut portion; i.e., if intending to turn right, first swing slightly left, then right. This will assist in getting the machine more quickly aligned for the next pass. Follow the same procedure for turning in the opposite direction. It is a good practice to try to make as short of a turn as possible. However, turn in a wider arc during warmer weather to minimize the possibility of bruising the turf.

      Important: The machine should never be stopped on a green with the cutting unit reels operating as damage to the turf may result. Stopping on a wet green with the machine may leave marks or indentations from the wheels.

    6. Finish cutting the green by mowing the outer periphery. Be sure to change the direction of cutting from the previous mowing. Always keep weather and turf conditions in mind and be sure to change the direction of mowing from the previous cutting. Replace the flag.

      At the end of the periphery cut, momentarily pull back on the raise/lower mow lever to shut the reels off without raising them. Continue moving forward until the reel stops rotating, then, drive off the green and raise the reels (This will help prevent dribbling grass onto the green while raising the reels).

    7. Empty the grass baskets of all clippings before transporting to the next green. Heavy wet clippings place an undue strain on the baskets and will add unnecessary weight to the machine, thereby increasing the load on the engine, hydraulic system, brakes, etc.

    Transporting the Machine

    Use a heavy-duty trailer or truck to transport the machine. Ensure that the trailer or truck has all necessary brakes, lighting, and marking as required by law. Please carefully read all the safety instructions. Knowing this information could help you, your family, pets, or bystanders avoid injury.

    Warning

    Driving on the street or roadway without turn signals, lights, reflective markings, or a slow moving vehicle emblem is dangerous and can lead to accidents causing personal injury.

    Do not drive machine on a public street or roadway.

    1. If using a trailer, connect it to the towing vehicle and connect the safety chains.

    2. If applicable, connect the trailer brakes.

    3. Load the machine onto the trailer or truck.

    4. Shut off the engine, remove the key, set the brake, and close the fuel valve.

    5. Use the metal tie down loops on the machine to securely fasten the machine to the trailer or truck with straps, chains, cable, or ropes.

    Loading the Machine

    Use extreme caution when loading the machine onto a trailer or a truck. One full-width ramp that is wide enough to extend beyond the rear tires is recommended instead of individual ramps for each side of the machine (Figure 32). The lower rear section of the machine frame extends back between the rear wheels and serves as a stop for tipping backward. Having a full-width ramp provides a surface for the frame members to contact if the machine starts to tip backward. If it is not possible to use 1 full-width ramp, use enough individual ramps to simulate a full-width continuous ramp.

    The ramp should be long enough so that the angles do not exceed 15 degrees (Figure 32). A steeper angle may cause mower components to get caught as the unit moves from the ramp to the trailer or truck. Steeper angles may also cause the machine to tip backward. If loading on or near a slope, position the trailer or truck so that it is on the down side of the slope and the ramp extends up the slope. This minimizes the ramp angle. The trailer or truck should be as level as possible.

    Important: Do not attempt to turn the machine while on the ramp; you may lose control and drive off the side.

    Avoid sudden acceleration when driving up a ramp and sudden deceleration when backing down a ramp. Both maneuvers can cause the machine to tip backward.

    Warning

    Loading a machine onto a trailer or truck increases the possibility of backward tip-over and could cause serious injury or death.

    • Use extreme caution when operating a machine on a ramp.

    • Ensure that the ROPS is in the up position while using the seat belt when loading the machine. Ensure that the ROPS will clear the top of an enclosed trailer.

    • Use only a single, full-width ramp; do not use individual ramps for each side of the machine.

    • If you must use individual ramps, use enough ramps to create an unbroken ramp surface wider than the machine.

    • Do not exceed a 15-degree angle between the ramp and the ground or between the ramp and the trailer or truck.

    • Avoid sudden acceleration while driving the machine up a ramp to avoid tipping backward.

    • Avoid sudden deceleration while backing the machine down a ramp to avoid tipping backward.

    g000951

    Inspecting and Cleaning After Mowing

    After mowing, thoroughly wash the machine with a garden hose without a nozzle so excessive water pressure does not cause contamination and damage to seals and bearings. Never wash a warm engine or electrical connections with water.

    After cleaning, inspect the machine for possible hydraulic fluid leaks and damage or wear to hydraulic and mechanical components. Check the cutting units for sharpness. Also, lubricate the traction pedal and brake shaft assembly with SAE 30 oil or 31 spray lubricant to deter corrosion and help keep the machine performing satisfactorily during the next mowing operation.

    Towing the Machine

    In case of an emergency, you can tow the machine for 400 m (1/4 mile). But, this should not be a standard procedure.
