Activating, Charging, and Connecting the Battery

Warning

Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.

Note: If the battery is not filled with electrolyte or activated, purchase bulk electrolyte with 1.26 specific gravity from a local battery-supply outlet and add it to the battery.

Danger

Battery electrolyte contains sulfuric acid which is fatal when consumed and causes severe burns.

  • Do not drink electrolyte and avoid contact with skin, eyes, or clothing. Wear safety glasses to shield your eyes and rubber gloves to protect your hands.

  • Fill the battery where clean water is always available for flushing the skin.

  1. Remove the battery cover (Figure 3).

    g031567
  2. Remove the filler caps from the battery and slowly fill each cell until the electrolyte is just above the plates.

  3. Install the filler caps and connect a 3 to 4 A battery charger to the battery posts.

    Note: Charge the battery at a rate of 3 to 4 A for 4 to 8 hours.

    Warning

    Charging the battery produces gasses that can explode.

    • Keep sparks and flames away from battery.

    • Never smoke near the battery.

  4. When the battery is charged, disconnect the charger from the electrical outlet and battery posts.

  5. Remove the filler caps.

  6. Slowly add electrolyte to each cell until the level is up to the fill ring.

    Important: Do not overfill the battery. Electrolyte will overflow onto other parts of the machine and severe corrosion and deterioration will result.

  7. Install the filler caps.

  8. Install the positive cable (red) to the positive (+) terminal and the negative cable (black) to the negative (–) terminal of the battery and secure them with the bolts and nuts (Figure 4).

    Note: Ensure that the positive (+) terminal is all the way onto the post and the cable is positioned snug to the battery. The cable must not contact the battery cover.

    Warning

    Incorrect battery cable routing could damage the tractor and cables, causing sparks. Sparks can cause the battery gases to explode, resulting in personal injury.

    • Always disconnect the negative (black) battery cable before disconnecting the positive (red) cable.

    • Always connect the positive (red) battery cable before connecting the negative (black) cable.

    g031568

    Important: If you ever remove the battery, install the battery-clamp bolts with the bolt heads positioned on the bottom side and the nuts on the top side. If the clamp bolts are reversed, they may interfere with the hydraulic tubes when shifting the cutting units.

  9. Coat both battery connections with Grafo 112X (skin over) grease (Toro Part No. 505-47), petroleum jelly, or light grease to prevent corrosion.

  10. Slide the rubber boot over the positive terminal to prevent a possible short from occurring.

  11. Install the battery cover.

Checking the Angle Indicator

Parts needed for this procedure:

Inclinometer1
  1. Park the machine on a flat, level surface.

  2. Verify that the machine is level by placing a handheld inclinometer (supplied with the machine) on the frame cross rail, by the fuel tank (Figure 5).

    Note: The inclinometer should read 0° when viewed from the operating position.

    g031569
  3. If the inclinometer does not read 0°, move the machine to a different location to obtain a 0° reading.

    Note: The angle indicator, mounted on the machine, should now read 0° also.

  4. If the angle indicator does not read 0°, loosen the 2 screws and nuts securing the angle indicator to the mounting bracket, adjust the indicator to obtain a 0° reading, and tighten the bolts.

Adjusting the Lift Arms

  1. Start the engine, raise the cutting units, and ensure that the clearance between each lift arm and the floor-plate bracket is 5 to 8 mm (0.18 to 0.32 inches) as shown in Figure 6.

    g031571

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

    1. Back off the stop bolts (Figure 7).

      g031572
    2. Back off the jam nut on the cylinder (Figure 8).

      g031573
    3. Remove the pin from the rod end and rotate the clevis.

    4. Install the pin and check the clearance.

      Note: Repeat the procedure if required.

    5. Tighten the clevis jam nut.

  2. Ensure that the clearance between each lift arm and stop bolt is 0.13 to 1.02 mm (0.005 to 0.040 inches) as shown in Figure 7.

    Note: If the clearance is not in this range, adjust the stop bolts to attain the proper clearance.

  3. Start the engine, raise the cutting units, and ensure 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) as shown in Figure 9.

    g031574

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

    Note: If the rear-lift arm clunks during transport, you can reduce clearance.

    1. Lower the cutting units and back off the jam nut on the cylinder (Figure 10).

      g031575
    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.

      Note: 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.

Adjusting the Carrier Frame

Adjusting the Front Cutting Decks

The front and rear cutting decks require different mounting positions. The front cutting deck has 2 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 inches) range, mount the front carrier frames in the lower, front mounting holes (Figure 11).

    Note: This permits more up travel of the cutting decks relative to the machine when approaching sudden changes in uphill terrain. It does, however, limit the clearance of the chamber to the carrier when cresting sharp, small hills.

    g031576
  2. For heights of cut in the 6.3 to 10 cm (2-1/2 to 4 inches) range, mount the front carrier frames in the upper, front mounting holes (Figure 11).

    Note: This increases the chamber to carrier clearance due to the higher position of the cutting chamber, but causes the cutting deck to reach its maximum up travel more quickly.

Adjusting the Rear Cutting Deck

The front and rear cutting decks require different mounting positions. The rear cutting deck has 1 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 11).

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 the rotary cutting decks bench set 6 mm (1/4 inch) above that of the reels cutting in the same area.

Important: Access to the rear cutting units is greatly improved by removing the cutting unit from the machine. If the machine is equipped with a Sidewinder® unit, side-wind 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, shut off the engine, and remove the ignition key.

  2. Loosen the bolt securing each height-of-cut bracket to the height-of-cut plate (front and each side) as shown in Figure 12.

    g031577
  3. Beginning with the front adjustment, remove the bolt.

  4. While supporting the chamber, remove the spacer (Figure 12).

  5. Move the chamber to the desired height of cut and install a spacer into the designated height-of-cut hole and slot (Figure 13).

    g205068
  6. Position the tapped plate in line with the spacer.

  7. Install the bolt (finger tight).

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

  9. Tighten the 3 bolts to 41 N∙m (30 ft-lb).

    Note: 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 (1-1/4 to 2-3/4 inches) height of cut).

Adjusting the Roller Scraper

Optional

The optional rear roller scraper works best when there is an even gap of 0.5 to 1 mm (0.02 to 0.04 inch) between the scraper and the roller.

  1. Loosen the grease fitting and the mounting screw (Figure 14).

    g031578
  2. Slide the scraper up or down until you obtain a gap of 0.5 to 1 mm (0.02 to 0.04 inch) between the rod and the roller.

  3. Tighten 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 wall of the chamber.

  2. Install the mulching baffle in the rear opening and secure it with 5 flange-head bolts (Figure 15).

    g031579
  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.

Before Operation Safety

General Safety

  • Never allow children or untrained people to operate or service the machine. Local regulations may restrict the age of the operator. The owner is responsible for training all operators and mechanics.

  • Become familiar with the safe operation of the equipment, operator controls, and safety signs.

  • Know how to stop the machine and engine quickly.

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

  • Before mowing, always inspect the machine to ensure that the blades, blade bolts, and cutting assemblies are in good working condition. Replace worn or damaged blades and bolts in sets to preserve balance.

  • Inspect the area where you will use the machine and remove all objects that the machine could throw.

Fuel Safety

  • Use extreme care in handling fuel. It is flammable and its vapors are explosive.

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

  • Use only an approved fuel container.

  • Never remove the fuel cap or fill the fuel tank while the engine is running or hot.

  • Never refuel the machine in an enclosed space.

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

  • If you spill fuel, do not attempt to start the engine; avoid creating any source of ignition until the fuel vapors have dissipated.

Filling the Fuel Tank

  • Fuel tank capacity: 38 L (10 US gallons)

  • Recommended Fuel:

    • For best results, use only clean, fresh (less than 30 days old), unleaded gasoline with an octane rating of 87 or higher ((R+M)/2 rating method).

    • Ethanol: Gasoline with up to 10% ethanol (gasohol) or 15% MTBE (methyl tertiary butyl ether) by volume is acceptable. Ethanol and MTBE are not the same. Gasoline with 15% ethanol (E15) by volume is not approved for use. Never use gasoline that contains more than 10% ethanol by volume, such as E15 (contains 15% ethanol), E20 (contains 20% ethanol), or E85 (contains up to 85% ethanol). Using unapproved gasoline may cause performance problems and/or engine damage which may not be covered under warranty.

    • Do not use gasoline containing methanol.

    • Do not store fuel either in the fuel tank or fuel containers over the winter unless a fuel stabilizer is used.

    • Do not add oil to gasoline.

Important: Do not use fuel additives other than a fuel stabilizer/conditioner. Do not use fuel stabilizers with an alcohol base such as ethanol, methanol, or isopropanol.

  1. Clean the area around the fuel-tank cap (Figure 21).

  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 spilled fuel.

    g008884

    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.

    • Before removing the fuel-tank cap, make sure that the vehicle is positioned on a level surface. Open the fuel-tank cap slowly.

    • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills.

    • Never fill the fuel tank inside an enclosed trailer.

    • 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 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.

    • Do not operate without entire exhaust system in place and in proper working condition.

    Danger

    In certain conditions during fueling, static electricity can be released causing a spark which can ignite the fuel vapors. A fire or explosion from fuel can burn you and others and can damage property.

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

    • Do not fill the 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 gas-powered equipment from the truck or trailer and refuel the equipment with the wheels on the ground.

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

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

Selecting a Blade

Using a Standard-Combination Sail Blade

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

Attributes: It has excellent lift and dispersion in most conditions.

Using an Angled-Sail Blade

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

Attributes:

  • The discharge remains more even at lower heights of cut.

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

  • There is a lower power requirement at lower heights of cut and in dense turf.

Using a High-Lift-Parallel Sail Blade

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

Attributes:

  • There is more lift and a 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.

  • It requires more horsepower to run.

  • It tends to discharge further left and tends to windrow at lower heights of cut.

Warning

Using the high-lift blade with the mulching baffle may cause the blade to break, resulting in personal injury or death.

Do not use the high-lift blade with the mulching baffle.

Using an Atomic Blade

Attributes: This blade provides excellent leaf mulching.

    Slope Safety

    • Establish your own procedures and rules for operating on slopes. These procedures must include surveying the site to determine which slopes are safe for machine operation. Always use common sense and good judgment when performing this survey.

    • Slopes are a major factor related to loss-of-control and tip-over accidents, which can result in severe injury or death. Operating the machine on any slope requires extra caution.

    • Operate the machine at a lower speed when you are on a slope.

    • If you feel uneasy operating the machine on a slope, do not do it.

    • Watch for holes, ruts, bumps, rocks, or other hidden objects. Uneven terrain could overturn the machine. Tall grass can hide obstacles.

    • Choose a low ground speed so you will not have to stop or shift while on a slope.

    • A rollover can occur before the tires lose traction.

    • Avoid operating the machine on wet grass. Tires may lose traction; regardless if the brakes are available and functioning.

    • Avoid starting, stopping, or turning the machine on a slope.

    • Keep all movement on slopes slow and gradual. Do not suddenly change the speed or direction of the machine.

    • Do no operate the machine near drop-offs, ditches, embankments, or bodies of water. The machine could suddenly roll over if a wheel goes over the edge or the edge caves in. Establish a safety area between the machine and any hazard (2 machine widths).

    Starting the Engine

    1. Ensure that the parking brake is engaged and the cutting-unit-drive switch is in the DISENGAGE position.

    2. Remove your foot from the traction pedal and ensure 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 START position to engage the starter motor.

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

    5. Release the key when the engine starts.

      Note: The key automatically moves to the ON/RUN position.

    6. When you start the engine for the first time or after overhauling the engine, operate the machine in forward and reverse for 1 to 2 minutes.

      Note: Also, operate the lift lever and cutting-unit-drive switch to ensure that all parts operate properly.

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

    Shutting Off the Engine

    Move the throttle control to the IDLE position, move the cutting-unit-drive switch to the DISENGAGE position, and rotate the starter key to the OFF position. Remove the key to prevent accidental starting.

    Standard-Control Module (SCM)

    The Standard-Control Module (SCM) is a potted electronic device produced in a 1-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-monitor input includes 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 an LED that illuminates when the specific circuit is energized. Use the input LEDs for switch and input-circuit troubleshooting.

    Output circuits are energized by an appropriate set of input conditions. The 3 outputs include PTO, ETR, and START. Output LEDs monitor the relay condition, indicating the presence of voltage at 1 of 3 specific output terminals.

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

    The SCM does not connect to an external computer or handheld device, cannot be programmed again, and does not record intermittent fault troubleshooting data.

    The decal on the SCM includes only symbols. The 3 LED output symbols are shown in the output box, while all other LEDs are inputs as shown in Figure 22.

    g031611

    Here are the logical troubleshooting steps for the SCM device.

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

    2. Move key switch to the ON position and ensure that the red, power LED illuminates.

    3. Move all of the input switches to ensure that all LEDs change state.

    4. Position the input devices at the appropriate position to achieve the appropriate output.

      Note: Use the following logic chart to determine the appropriate input condition.

    5. Review the following repair options if a specific output LED illuminates.

      • If a specific output LED illuminates without the appropriate output function, check the output harness, connections, and component.

        Note: Repair as required.

      • If a specific output LED does not illuminate, check both fuses.

      • If a specific output LED does not illuminate and the inputs are in the appropriate condition, install a new SCM and determine if the 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 chart.

    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 to ensure that it matches the logic chart.

    If the input LEDs are correct, check the output LED. If the output LED illuminates but the device is not energized, measure the available voltage at the output device, the continuity of the disconnected device, and the potential voltage on the ground circuit (floating ground).

    Operating Tips

    Creating a Site Survey

    To perform a site survey, lay a 1.25 m plank (4 ft long 2 x 4) on the slope surface and measure the angle of the slope with the inclinometer provided with the machine. The plank (2 x 4) will average the slope but will not take into consideration dips or holes which can cause a sudden change in side hill angle. After completing the site survey, refer to Slope Safety.

    Additionally, the machine is equipped with an angle indicator mounted on the steering tube. This indicates the side hill angle that the machine is on.

    Always wear your seat belt.

    Operating the Machine

    • 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 the machine, remove your foot from the traction pedal and let it return to NEUTRAL or press down on the reverse pedal.

      Note: When going downhill in the machine, you may need to use the reverse pedal to stop.

    • 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 the machine on a hill.

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

    • On the Sidewinder unit, get accustomed to the reach of the cutting units so that you do not hang them up or damage them.

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

    • Always drive slowly in rough areas.

    • The Sidewinder unit 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 mow around it.

    • When transporting the machine from 1 work area to another, raise the cutting units to the fully upward position, move the mow/transport slide to the left to transport, and place the throttle in the FAST position.

    Changing Mowing Patterns

    Change mowing patterns often to minimize a poor after-cut appearance from repeatedly mowing in the same direction.

    Understanding Counterbalance

    The counterbalance system maintains hydraulic back pressure on the deck-lift cylinders. This counterbalance pressure transfers mower deck weight to the mower drive wheels to improve traction. The counterbalance pressure has been set at the factory to an optimal balance of after-cut appearance and traction capability in most turf conditions. Decreasing the counterbalance setting can produce a more stable mower deck, but can decrease the traction capability. Increasing the counterbalance setting can increase the traction capability, but may result in a poor after-cut appearance. Refer to the Service Manual for your traction unit for instructions to adjust the counterbalance pressure.

    Resolving After-Cut Appearance

    Reference the After-cut Appearance Troubleshooting Guide available at www.Toro.com.

    Using Proper 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 up for your next pass.

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

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

    • Bolt-in mulching baffles are available for the cutting units. The mulching baffles perform well when you maintain turf on a regular schedule to avoid removing more than 25 mm (1 inch) of growth per cutting. When you cut too much growth with the mulching baffles installed, the 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.

    Mowing When the Grass Is Dry

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

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

    Remove approximately 25 mm (1 inch), or no more than 1/3 of the grass blade when cutting. In exceptionally lush and dense grass, you may need to raise your height-of-cut setting.

    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. Ensure that the blade is in good condition and that there is a full sail.

    Checking the Condition of the Mower Deck

    Ensure that the cutting chambers are in good condition. Straighten any bends in the chamber components to ensure correct blade tip/chamber clearance.

    Maintaining the Machine After Mowing

    After mowing, thoroughly wash the machine with a garden hose with no nozzle to avoid contamination and damage to the seals and bearings caused by excessive water pressure. Ensure that the radiator and oil cooler are kept free of dirt or grass clippings. After cleaning, inspect the machine for possible hydraulic-fluid leaks, damage, or wear to the hydraulic and mechanical components, and check the cutting-unit blades for sharpness.

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

    After Operation

    After Operation Safety

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

    • If the cutting units are in the transport position, use the positive mechanical lock (if available) before you leave the machine unattended.

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

    • Shut off the fuel before storing or transporting the machine.

    Engine Maintenance

    Engine Safety

    • Shut off the engine before checking the oil or adding oil to the crankcase.

    • Do not change the governor speed or overspeed the engine.

    Servicing the Air Cleaner

    Maintenance Service IntervalMaintenance Procedure
    Every 200 hours
  • Service the Air Cleaner(More frequently in extreme dusty or dirty conditions)
  • Inspect the air cleaner and hoses periodically to maintain maximum engine protection and to ensure maximum service life. Check the air-cleaner body for damage, which could cause an air leak. Replace a damaged air-cleaner body.

    Inspect and change the air-cleaner filter as described in the following procedure:

    1. Pull the latch outward and rotate the air-cleaner cover counterclockwise.

      g002401
    2. Before removing the filter, use low-pressure air (40 psi, clean and dry) to help remove large accumulations of debris packed between the outside of the primary filter and the canister.

      Important: 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 you remove the primary filter.

    3. Remove and replace the primary filter.

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

    4. Inspect the new filter for shipping damage, checking the sealing end of the filter and the body.

      Important: Do not use a damaged filter.

    5. Insert the new filter by applying pressure to the outer rim of the element to seat it in the canister.

    6. Clean the dirt ejection port located in the removable cover. Remove the rubber outlet valve from the cover, clean the cavity, and replace the outlet valve.

    7. Install the cover orienting the rubber, outlet valve in a downward position, between approximately 5 o'clock to 7 o'clock when viewed from the end (Figure 41).

    8. Secure the cover latches.

    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 3.3 L (3.5 US qt) with the filter.

    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, additional oil is not required.The engine uses any high-quality 10W-30 detergent oil having the American Petroleum Institute (API) service classification SJ, SK, SL, SM, or higher. Choose a viscosity according to the table in Figure 42.

    g016095
    1. Position the machine on a level surface and open the hood.

    2. Remove the dipstick (Figure 43) and wipe it with a clean rag. Insert the dipstick into the tube and make sure that it is seated fully. Remove the dipstick and check the level-of-the-oil.

      g008881
    3. If the oil level is low, remove the filler cap (Figure 44) and add enough oil to raise the level-of-the-oil to the Full mark on the dipstick.

      Note: When adding oil, remove the dipstick to allow proper venting. Pour oil slowly and check the level-of-the-oil often during this process. Do not overfill.

      Important: 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 44. This clearance is necessary to permit venting when filling, which prevents oil from overrunning into the breather.

      g002373
    4. Install the dipstick firmly in place.

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

    Changing the Engine Oil and Filter

    Replacing the Spark Plugs

    Maintenance Service IntervalMaintenance Procedure
    Every 400 hours
  • Replace the spark plugs.
  • The spark plugs usually last a long time; however, remove and check the plugs whenever the engine malfunctions or every 400 hours. Replace the spark plugs to ensure proper engine performance and reduce exhaust emission level.

    The correct spark plug to use is a Champion RC 14YC or NGK BPR 4ES.

    1. Clean the area around the spark plugs so foreign matter cannot fall into the cylinder when you remove the spark plug.

    2. Pull the wires off the spark plugs and remove the plugs from the cylinder head.

    3. Check the condition of the side electrode, center electrode, and center-electrode insulator to ensure that there is no damage.

      Important: A cracked, fouled, dirty, or otherwise malfunctioning spark plug must be replaced. Do not sand blast, scrape, or clean electrodes by using a wire brush because grit may eventually release from the plug and fall into the cylinder. The result is usually a damaged engine.

      g005588
    4. Set the air gap on each plug between the center and side electrodes to 0.81 mm (0.032 inch).

    5. Install the correctly-gapped spark plugs and tighten them to 24.5 to 29 N-m (18 to 22 ft-lb). If you cannot use a torque wrench, tighten the plugs firmly.

    6. Install the spark-plug wires.

    The rotary deck comes from the factory preset at 5 cm (2 inches) height-of-cut and blade rake of 7.9 mm (0.31 inch). The left and right heights of cut are also preset to within ± 0.7 mm (0.03 inch) of the other.

    The cutting deck is designed to withstand blade impacts without deforming the chamber. If the blade strikes a solid object, 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.

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

    2. Mark an end of the blade with a paint pen or marker.

      Note: Use this end of the blade to check all heights.

    3. Position the cutting edge of the marked end of the blade at the 12 o’clock position (straight ahead in the direction of mowing) and measure the height from the table to the cutting edge of the blade (Figure 65).

      g011353
    4. Rotate the marked end of the blade to the 3 o’clock and 9 o’clock positions and measure the heights (Figure 65).

    5. Compare the 12 o’clock position measured height to the height-of-cut setting.

      Note: It should be within 0.7 mm (0.03 inch). The 3 o’clock and 9 o’clock heights should be 3.8 ± 2.2 mm (0.15 ± 0.09 inch) higher than the 12 o’clock setting and within 2.2 mm (0.09 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 1 bracket at a time).

    1. Remove the height-of-cut bracket (front, left, or right) from the deck frame (Figure 66).

      g031647
    2. Adjust the 1.5 mm (0.06 inch) shims and/or 0.7 mm (0.03 inch) shim between the deck frame and bracket to achieve the desired height of cut (Figure 66).

    3. Install the height-of-cut bracket to the deck frame with the remaining shims assembled below the height-of-cut bracket (Figure 66).

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

      Note: The socket-head bolt and spacer are held together with Loctite to prevent the spacer from falling inside the deck frame.

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

    6. Determine if you need to adjust only 1 or both (right and left side) height-of-cut brackets.

      Note: If the 3 o’clock or 9 o’clock side is 3.8 ± 2.2 mm (0.15 ± 0.09 inch) higher than the new front height, then you do not need to adjust for that side. Adjust the other side to within ± 2.2 mm (0.09 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. Verify the 12, 3, and 9 o’clock heights.

    Servicing the Blade

    Removing the Blade

    Replace the blade if it hits a solid object, the blade is out of balance, or if the blade is bent. Always use genuine Toro replacement blades to ensure safety and optimum performance. Never use replacement blades made by other manufacturers, because they could be dangerous.

    1. Perform the pre-maintenance procedure; refer to Preparing the Machine for Maintenance.

    2. Block the cutting deck to prevent it from falling accidentally.

    3. Grasp the end of the blade using a rag or thickly padded glove and remove the blade bolt, anti-scalp cup, and blade from the spindle shaft (Figure 67).

      g011355
    4. Install the blade with the sail facing toward the cutting deck, with the anti-scalp cup and blade bolt (Figure 67).

    5. Tighten blade bolt to 115 to 149 N∙m (85 to 110 ft-lb).

    Inspecting and Sharpening the Blade

    1. Perform the pre-maintenance procedure; refer to Preparing the Machine for Maintenance.

    2. Block the cutting deck to prevent it from falling accidentally.

    3. Examine the cutting ends of the blade carefully, especially where the flat and curved parts of the blade meet (Figure 68).

      Note: Because 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 you notice wear, replace the blade; refer to Removing the Blade.

      g031648
    4. Inspect the cutting edges of all the 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 ensure sharpness (Figure 69).

      Note: The blade remains balanced if the same amount of metal is removed from both cutting edges.

      g006926
    5. To check the blade for being straight and parallel, lay the blade on a level surface and check its ends.

      Note: 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 produces a good quality of cut and requires minimal power from the engine. By contrast, replace a blade that is higher at the ends than the center or the cutting edge is higher than the heel, because the blade is bent or warped.

    6. Install the blade with the sail facing toward the cutting deck, with the anti-scalp cup and blade bolt.

    7. Tighten the blade bolt to 115 to 149 N∙m (85 to110 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 completely stop in 7 seconds after you shut down the cutting deck.

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

    To verify the stopping time, have a second person stand back from the deck at least 6 m (20 ft) and watch the blades on 1 of the cutting decks. Shut the cutting decks down and record the time that it takes for the blades to come to a complete stop. If the time is longer than 7 seconds, the braking valve needs adjustment; contact your Toro Distributor for assistance in making this adjustment.
