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

  • Engage the parking brake, shut off the machine, remove the key, and wait for all movement to stop before you leave the operator’s position. Allow the machine to cool before adjusting, servicing, cleaning, or storing it.

  • Know how to stop the machine and shut off the machine quickly.

  • Check that operator-presence controls, safety switches, and safety protective devices 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 cutting units are in good working condition.

  • 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.

  • Do not remove the fuel cap or fill the fuel tank while the engine is running or hot.

  • Do not add or drain fuel in an enclosed space.

  • Do not 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: 22.7 L (6 U.S. gallons)

  • Recommended Fuel:

    • For best results, 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.

    • 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. 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.

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

    • 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 around the fuel-tank cap and remove it (Figure 21).

    g005112
  2. Fill the tank until the level is 6 to 13 mm (1/4 to 1/2 inch) below the bottom of the filler neck.

    Important: Do not overfill.

  3. Install the cap.

  4. Wipe up any fuel that may have spilled.

    During Operation

    During Operation Safety

    General Safety

    • The owner/operator can prevent and is responsible for accidents that may cause personal injury or property damage.

    • Wear appropriate clothing, including eye protection; long pants; and substantial, slip-resistant footwear. Tie back long hair and do not wear loose clothing or loose jewelry.

    • Do not operate the machine while ill, tired, or under the influence of alcohol or drugs.

    • Use your full attention while operating the machine. Do not engage in any activity that causes distractions; otherwise, injury or property damage may occur.

    • Before you start the engine, ensure that all drives are in neutral, the parking brake is engaged, and you are in the operating position.

    • Do not carry passengers on the machine.

    • Keep bystanders and children out of the operating area. If co-workers must be present, use caution and ensure that the grass baskets are installed on the machine.

    • Operate the machine only in good visibility to avoid holes or hidden hazards.

    • Avoid mowing on wet grass. Reduced traction could cause the machine to slide.

    • Keep your hands and feet away from the cutting units.

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

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

    • Stop the cutting units whenever you are not mowing.

    • Slow down and use caution when making turns and crossing roads and sidewalks with the machine. Always yield the right-of-way.

    • Operate the engine only in well-ventilated areas. Exhaust gases contain carbon monoxide, which is lethal if inhaled.

    • Do not leave a running machine unattended.

    • Before you leave the operating position, do the following:

      • Park the machine on a level surface.

      • Lower the cutting units to the ground and ensure that they are disengaged.

      • Engage the parking brake.

      • Shut off the engine and remove the key.

      • Wait for all movement to stop.

    • Operate the machine only in good visibility and appropriate weather conditions. Do not operate the machine when there is the risk of lightning.

    Rollover Protection System (ROPS) Safety

    • Do not remove any of the ROPS components from the machine.

    • Ensure that the seat belt is attached and that you can release it quickly in an emergency.

    • Always wear your seat belt.

    • Check carefully for overhead obstructions and do not contact them.

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

    • Replace all damaged ROPS components. Do not repair or alter them.

    Slope Safety

    • Slopes are a major factor related to loss of control and rollover accidents, which can result in severe injury or death. You are responsible for safe slope operation. Operating the machine on any slope requires extra caution.

    • Evaluate the site conditions to determine if the slope is safe for machine operation, including surveying the site. Always use common sense and good judgment when performing this survey.

    • Review the slope instructions, listed below, for operating the machine on slopes. Before you operate the machine, review the site conditions to determine whether you can operate the machine in the conditions on that day and at that site. Changes in the terrain can result in a change in slope operation for the machine.

    • Avoid starting, stopping, or turning the machine on slopes. Avoid making sudden changes in speed or direction. Make turns slowly and gradually.

    • Do not operate a machine under any conditions where traction, steering, or stability is in question.

    • Remove or mark obstructions such as ditches, holes, ruts, bumps, rocks, or other hidden hazards. Tall grass can hide obstructions. Uneven terrain could overturn the machine.

    • Be aware that operating the machine on wet grass, across slopes, or downhill may cause the machine to lose traction. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering.

    • Use extreme caution when operating the machine near drop-offs, ditches, embankments, water hazards, or other hazards. 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.

    • Identify hazards at the base of the slope. If there are hazards, mow the slope with a pedestrian-controlled machine.

    • If possible, keep the cutting units lowered to the ground while operating on slopes. Raising the cutting units while operating on slopes can cause the machine to become unstable.

    • Use extreme caution with grass-collection systems or other attachments. These can change the stability of the machine and cause a loss of control.

    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 operation is required for the break-in period.

    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.

    Starting the Engine

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

    Note: You may need to bleed the fuel system before starting the engine if any of the following situations have occurred:

    • Initial start up of a new engine.

    Before each use or daily
  • Check 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 you or damage to the machine.

    The safety-interlock system prevents the engine from starting unless:

    • The traction pedal is in the NEUTRAL position.

    • The functional-control lever is in the NEUTRAL position.

    The safety-interlock system prevents the machine from moving unless:

    • The parking brake is disengaged.

    • You are seated in the operator's seat.

    • The functional-control lever is in the MOW position or the TRANSPORT position.

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

    Checking the Traction Pedal

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the safety-interlock system.
  • Perform the following system checks daily to ensure that the interlock system is operating correctly:

    1. Sit on the seat, move the traction pedal to the NEUTRAL position, move the functional-control lever to the NEUTRAL position, and engage the parking brake.

    2. Try to move the traction pedal forward or backward.

      The pedal should not move, which indicates that the interlock system is operating correctly. Correct the problem if it is not operating properly.

    Checking the Function Control

    1. Sit on the seat, move the traction pedal to the NEUTRAL position, move the functional-control lever to the NEUTRAL position, and engage the parking brake.

    2. Move the functional-control lever to the MOW position or the TRANSPORT position and try to start the engine.

      The engine should not turnover or start, which indicates 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 the NEUTRAL position, move the functional-control lever to the NEUTRAL position, and engage the parking brake.

    4. Start the engine and move the functional-control lever to the MOW position or the TRANSPORT position.

      The engine should shut off, which indicates that the interlock system is operating correctly.

      Correct the problem if it is not operating properly.

    Checking the Operator’s Presence Switch

    1. Sit on the seat, move the traction pedal to the NEUTRAL position, move the functional control lever to the NEUTRAL position, and engage the parking brake.

    2. Start the engine.

    3. Release the parking brake, move the functional control lever to the MOW position, and rise from the seat.

      The engine should shut off, which indicates that the interlock system is operating correctly. Correct the problem if it is not operating properly.

    Checking the Raise/Lower Mow Control

    1. Sit on the seat, move the traction pedal to the NEUTRAL position, move the functional control lever to the NEUTRAL position, and engage the parking brake.

    2. Start the engine.

    3. Move the raise/lower mow control forward to lower the cutting units. The cutting units should lower but not start rotating.

      If they start rotating, the interlock system is not operating correctly; correct the problem before operating the machine.

    Driving the Machine without Mowing

    • Ensure that the cutting units are fully raised.

    • Move the functional-control lever to the TRANSPORT position.

    • Use the brakes to slow the machine while going down steep hills to avoid loss of control.

    • Always approach rough areas at a reduced speed and cross severe undulations carefully.

    • Familiarize yourself with the width of the machine. Do not attempt to pass between objects that are close together to prevent costly damage and downtime.

    Mowing the Green

    Important: If the leak detector alarm (if equipped on your model) sounds or you notice an oil leak while cutting on a green, immediately raise the cutting units, drive directly off the green, and stop the machine in an area away from the green. Determine the cause of the leak and correct the problem.

    Before mowing greens, find a clear area and practice performing basic machine functions (e.g., starting and stopping the machine, raising and lowering the cutting units, and turning).

    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 are less apt to lay down and therefore be difficult to trap between the reel blades and the bedknife.

    Cutting the Green

    1. Approach the green with the functional-control lever in the MOW position and the throttle at full speed.

    2. Start on 1 edge of the green so that you can use the ribbon procedure of cutting.

      Note: This holds compaction to a minimum and leaves a neat, attractive pattern on the greens.

    3. Push forward the raise/lower mow lever as the front edges of the grass baskets cross the outer edge of the green.

      Note: This procedure drops the cutting units to the turf and starts the reels.

      Important: The center cutting unit drops and raises slightly after the front cutting units do; therefore, you should practice gaining the required timing necessary to minimize the cleanup mowing operation.

      Note: The delay in raising and lowering the center cutting unit depends on hydraulic fluid temperature. Cold hydraulic fluid results in a longer delay. As the fluid temperature increases, the delay time becomes shorter.

    4. Overlap a minimal amount with the previous cut on return passes.

      Note: To assist in maintaining a straight line across the green and keeping the machine an equal distance from the edge of the previous cut, imagine a 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 23). 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.

    5. As the front edges of the baskets cross the edge of the green, pull back the raise/lower mow lever rearward and hold it until all the cutting units have risen. This stops the reels and lifts the cutting units.

      Important: Time this step correctly so that you do not cut into the fringe area, yet cut as much of the green as possible to minimize the amount of grass left to mow around the outer periphery.

    6. To cut down on operating time and to ease the lineup for the next pass, momentarily turn the machine in the opposite direction, then turn it in the direction of the uncut portion. This movement is a tear-shaped turn (Figure 22), which quickly lines the machine up for your next pass.

      g229671

      Note: Try to make as short of a turn as possible, except during warmer weather—a wider arc minimizes the turf bruising.

      g005116

      Note: The steering wheel does not return to its original position after you complete a turn.

      Important: Never stop the machine on a green while the cutting units are engaged, as damage to the turf may result. Stopping the machine on a wet green may leave marks or indentations from the wheels.

    Cutting the Periphery and Finishing the Job

    1. Finish cutting the green by mowing the outer periphery. Change the direction of cutting from the previous mowing.

      Note: Use the throttle lever to adjust the machine speed when you cut the periphery. This will match the clip to the green and may reduce triplex ring.

      Note: Always keep weather and turf conditions in mind and be sure to change the direction of mowing from the previous cutting.

    2. When finished mowing the outer periphery, tap the raise/lower mow lever rearward to stop the reels, then drive off the green. When all the cutting units are off the green, raise the cutting units.

      Note: This step minimizes grass clumps left on the green.

    3. Replace the flag.

    4. Empty the grass baskets of all clippings before you transport the machine to the next green.

      Note: Heavy wet clippings place an undue strain on the baskets and add unnecessary weight to the machine, which increases the load on the machine systems (e.g., engine, hydraulic system, and brakes).

    After Operation

    • 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 filter (more frequently when operating conditions are dusty or dirty).
    • Check the air-cleaner body for damage which could cause an air leak; replace it if it is damaged. Check the whole intake system for leaks, damage, or loose hose clamps.

    • Changing the air filter before it is necessary increases the chance of dirt entering the engine when the filter is removed.

    • Ensure that the cover is seated correctly and seals with the air cleaner body.

    1. Release the latches that secure the air-cleaner cover to the air-cleaner body (Figure 30).

      g008442
    2. Remove the cover from the air-cleaner body.

    3. Before removing the filter, use low pressure air (275 kPa (40 psi), clean and dry) to help remove large accumulations of debris packed between the outside of the primary filter and the canister. This cleaning process prevents debris getting into the intake when you remove the primary filter.

      Important: Avoid using high pressure air which could force dirt through the filter into the intake tract.

    4. Remove and replace the primary filter, as follows:

      Important: Do not clean the used element.

      1. Inspect the new filter for shipping damage; do not use a damaged element.

      2. Carefully pull the old filter out of the filter body and discard it.

      3. Insert the new filter by applying pressure to the outer rim of the element to seat it in the canister, checking the sealing end of the filter and the body.

        Important: Do not apply pressure to the flexible center of the filter.

    5. 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.

    6. 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.

    Servicing the Engine Oil

    Checking the Engine Oil

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the engine oil.
  • The engine is shipped with 3.7 L (3.9 US qt) (with filter) of oil in the crankcase; however, you must check the oil level before and after starting the engine the first time.

    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.

    Important: Keep the engine oil level between the upper and lower limits on the oil gauge; the engine may fail if you run it with too much or too little oil.

    1. Park the machine on a level surface, shut off the engine and remove the key.

    2. Remove the dipstick and wipe it with a clean rag (Figure 32).

      Important: Remove the dipstick 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 31. This clearance is necessary to permit venting when filling, which prevents oil from overrunning into breather.

      g016415
      g016419
    3. Push the dipstick into the tube and make sure it is seated fully.

    4. Remove the dipstick from the tube and check the level of oil.

      Note: 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.

    5. Replace the dipstick.

    6. Start and run the engine at idle for 30 seconds, then shut the engine off. Wait 30 seconds, then repeat steps 2 through 5.

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