  • 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

53 L (14 US gallons)

Fuel Specification

Important: Use only ultra-low sulphur diesel fuel. Fuel with higher rates of sulfur degrades the diesel oxidation catalyst (DOC), which causes operational problems and shortens the service life of engine components.Failure to observe the following cautions may damage the engine.

  • Never use kerosene or gasoline instead of diesel fuel.

  • Never mix kerosene or used engine oil with the diesel fuel.

  • Never keep fuel in containers with zinc plating on the inside.

  • Do not use fuel additives.

Petroleum Diesel

Cetane rating: 45 or higher

Sulfur content: Ultra-low sulfur (<15 ppm)

  • Use only clean, fresh diesel fuel or biodiesel fuels.

  • 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 fuel (No. 1-D or No. 1-D/2-D blend) below that temperature.

Note: Use of winter-grade fuel at lower temperatures provides lower flash point and cold flow characteristics which eases starting and reduces fuel filter plugging.Using summer-grade fuel above -7°C (20°F) contributes toward longer fuel pump life and increased power compared to winter-grade fuel.

Biodiesel

This machine can also use a biodiesel blended fuel of up to B20 (20% biodiesel, 80% petroleum diesel).

Sulfur content: Ultra-low sulfur (<15 ppm)

Biodiesel fuel specification: ASTM D6751 or EN14214

Blended fuel specification: ASTM D975, EN590, or JIS K2204

Important: The petroleum diesel portion must be ultra-low sulfur.

Observe the following precautions:

  • Biodiesel blends may damage painted surfaces.

  • 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 authorized Toro distributor for more information on biodiesel.

Adding Fuel

  1. Park the machine on a level surface, lower the cutting units, engage the parking brake, shut off the engine, and remove the key.

  2. Using a clean rag, clean area around fuel-tank cap.

    • Wear appropriate clothing, including eye protection; long trousers; substantial, slip-resistant footwear; and hearing protection. 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 and keep bystanders and children out of the operating area.

    • 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 operator’s position, do the following:

      • Park the machine on a level surface.

      • Disengage and lower the cutting units.

      • Engage the parking brake.

      • Shut off the engine and remove the key.

      • Wait for all movement to stop.

      • Allow the machine to cool before adjusting, servicing, cleaning, or storing it.

    • 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.

      • 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.

    Starting the Engine

    Important: The fuel system automatically bleeds itself when any of the following situations occur:

    • You are starting a new machine for the first time.

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

    • Maintenance has been performed upon the fuel system components.

    1. Sit on the seat, keep your foot off the traction pedal so that it is in NEUTRAL, engage the parking brake, set the engine-speed switch to the MIDDLE position, and ensure that the Enable/Disable switch is in the DISABLE position.

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

    3. Turn the key to the RUN position.

    4. When the glow indicator dims, turn the key to the START position. Release the key immediately when the engine starts and allow it to return to the RUN position. Allow the engine to warm up (without load), then move the throttle control to the desired position.

    Hydraulic Filter-Restriction Indicator

    The hydraulic system is equipped with a hydraulic filter-restriction indicator (Figure 50). With the engine running at operating temperature, view the indicator; it should be in the green zone. When the indicator is in the red zone, change the hydraulic filters.

    1. Move all controls to NEUTRAL, engage the parking brake, move the engine-speed switch to the low idle position and allow the engine to reach low idle speed.

    2. Turn the key to the OFF position and remove it from the switch.

    Cutting Grass with the Machine

    Note: Cutting grass at a rate that loads the engine promotes DPF regeneration.

    1. Move the machine to the job site and align the machine outside the cutting area for the first cutting pass.

    2. Ensure that the PTO switch is set to the DISABLE position.

    3. Move the lever for the mow-speed limiter forward.

    4. Press the throttle-speed switch to set the engine speed to HIGH IDLE.

    5. Use the joystick to lower the cutting units to the ground.

    6. Press the PTO switch to prepare cutting units for operation.

    7. Use the joystick to raise the cutting units off the ground.

    8. Begin moving the machine toward the cutting area and lower the cutting units.

      Note: Cutting grass at a rate that loads the engine promotes DPF regeneration.

    9. When you complete the mowing pass, use the joystick to lift the cutting units.

    10. Perform a tear-shaped turn to quickly line up for your next pass.

    Adjusting the Turf-Compensation Spring

    The turf-compensation spring (Figure 51) transfers the weight from the front roller to the rear roller. This helps to reduce a wave pattern in the turf, also known as marcelling or bobbing.

    Important: Make spring adjustments with the cutting unit mounted to the traction unit, pointing straight ahead, and lowered to the shop floor.

    1. Make sure that the hairpin is installed in the rear hole in the spring rod (Figure 51).

      Note: When servicing the cutting unit, move the hairpin to the spring-rod hole next to the turf-compensation spring.

      g003863
    2. Tighten the hex nuts on the front end of the spring rod until the compressed length of the spring is 15.9 cm (6.25 inches); refer to Figure 51.

      Note: When operating on rough terrain decrease the spring length by 13 mm (1/2 inch). Ground following will be slightly decreased.

      Note: The turf compensation setting will need to be reset if the HOC setting or the Aggressiveness of Cut setting is changed.

    Adjusting the Lift-Arm Counterbalance

    Rear Cutting Units

    Caution

    The springs are under tension and could cause personal injury.

    Use caution when adjusting the springs.

    You can adjust the amount of counterbalance force applied to the rear cutting-units to help compensate for different turf conditions, and to maintain a uniform height of cut in rough conditions or in areas of thatch buildup.

    You adjust counterbalance force of each torsion spring to 1 of 4 settings. Each increment increases or decreases the counterbalance force on the cutting unit by 2.3 kg (5 lb). You can position the springs at the back side of the first spring actuator to remove all counterbalance (fourth position).

    Note: To remove all counterbalance force, position the long leg of the torsion spring above the shouldered stud.

    1. Park the machine on a level surface, lower the cutting units, shut off the engine, engage the parking brake, and remove the key.

    2. Insert the long end of the counterbalance spring into a tube or similar object, and pivot the spring around the shouldered stud to the desired position (Figure 52).

      g375585
    3. Repeat steps 1 and 2 at the other counterbalance spring.

    Adjusting the Lift-Arm Turnaround Position

    1. Park the machine on a level surface, lower the cutting units, shut off the engine, engage the parking brake, and remove the key.

    2. The lift-arm switch is located underneath the hydraulic tank and inboard of the cutting unit #5 lift arm (Figure 31).

      g375697
    3. Loosen the jam nut that secures lift-arm switch to the switch plate (Figure 54).

      g375696
    4. Adjust the lift-arm switch as follows:

      • To increase the lift-arm turnaround height, move the switch down.

      • To decrease the lift-arm turnaround height, move the switch up.

    5. Tighten the jam nut.

    Setting the Reel Speed

    To achieve a consistent, high quality of cut and a uniform after-cut appearance, adjust the reel speed as follows:

    1. In the InfoCenter, under the settings menu, enter the blade count, mow speed, and HOC to calculate the proper reel speed.

    2. If further adjustments are required, in the settings menu, scroll down to the F Reel RPM, R Reel RPM, or both.

    3. Press the right button to change the reel-speed value.

      Note: As you change the speed setting, the display continues to show the calculated reel speed based on blade count, mow speed and HOC, but the new value is also be displayed.

      Note: You may need to increase or decrease the reel speed to compensate for varying turf conditions.

    g031995
    g031996

    Understanding the Diagnostic Light

    The machine is equipped with a diagnostic light, which indicates if the machine detects a malfunction. The diagnostic light is located on the InfoCenter, above the display screen (Figure 57). When the machine is functioning properly and the key switch is moved to the ON/RUN position, the diagnostic light turns on briefly to indicate that the light is working properly. When a machine advisory message appears, the light illuminates when the message is present. When a fault message appears, the light blinks until the fault is resolved.

    g021272

    Diesel Particulate Filter Regeneration

    The diesel particulate filter (DPF) is part of the exhaust system. The diesel-oxidation catalyst of the DPF reduces harmful gasses and the soot filter removes soot from the engine exhaust.

    The DPF regeneration process uses heat from the engine exhaust to incinerate the soot accumulated on the soot filter, converting the soot to ash, and clears the channels of the soot filter so that filtered engine exhaust flows out the DPF.

    The engine computer monitors the accumulation of soot by measuring the back pressure in the DPF. If the back pressure is too high, soot is not incinerating in the soot filter through normal engine operation. To keep the DPF clear of soot, remember the following:

    • Passive regeneration occurs continuously while the engine is running—run the engine at full engine speed when possible to promote DPF regeneration.

    • If the back pressure in the DPF is too high or a reset regeneration has not occurred for 100 hours, the engine computer signals you through the InfoCenter when reset regeneration is running.

    • Allow the reset regeneration process to complete before shutting off the engine.

    Operate and maintain your machine with the function of the DPF in mind. Engine load at high idle (full throttle) engine speed generally produces adequate exhaust temperature for DPF regeneration.

    Important: Minimize the amount of time that you idle the engine or operate the engine at low-engine speed to help reduce the accumulation of soot in the soot filter.

    DPF Soot Accumulation

    • Over time, the diesel particulate filter accumulates soot in the soot filter. The computer for the engine monitors the soot level in the DPF.

    • When enough soot accumulates, the computer informs you that it is time to regenerate the DPF.

    • DPF regeneration is a process that heats the DPF to convert the soot to ash.

    • In addition to the warning messages, the computer reduces the power produced by the engine at different soot-accumulation levels.

    Engine Warning Messages—Soot Accumulation

    Level 2: Engine Warning
    g213867
    The computer de-rates the engine power to 50%.Perform a recovery regeneration as soon as possible; refer to Parked or Recovery Regeneration.

    DPF Ash Accumulation

    • The lighter ash is discharged through the exhaust system; the heavier ash collects in the soot filter.

    • Ash is a residue of the regeneration process. Over time, the diesel particulate filter accumulates ash that does not discharge with the engine exhaust.

    • The computer for the engine calculates the amount of ash accumulated in the DPF.

    • When enough ash accumulates, the engine computer sends information to the InfoCenter in the form of an engine fault to indicate the accumulation of ash in the DPF.

    • The fault messages indicate that it is time to service the DPF.

    • In addition to the warnings, the computer reduces the power produced by the engine at different ash-accumulation levels.

    • Never operate the engine in an enclosed area.

    • Make sure that there are no flammable materials around the exhaust system.

    • Never touch a hot exhaust system component.

    • Never stand near or around the exhaust pipe of the machine.

    g224417
    • The high exhaust-temperature icon Graphic displays in the InfoCenter (Figure 68).

    • The engine computer adjusts engine settings to raise the exhaust temperature.

      Important: The high exhaust-temperature icon indicates that the exhaust temperature discharged from of your machine may be hotter than during regular operation.

    • While operating the machine, run the engine at full engine speed and high load when possible to promote DPF regeneration.

    • The icon displays in the InfoCenter while the reset regeneration is processing.

    • Whenever possible, do not shut off the engine or reduce engine speed while the reset regeneration is processing.

      Danger

      Contacting the cutting units when they are moving could cause personal injury.

      To avoid personal injury, be certain that you are clear of the cutting units before proceeding.

      Important: Never use a short-handled brush.

    4. If the reels stall or become erratic while backlapping, select a higher reel-speed setting until the speed stabilizes, then return the reel speed to your desired speed.

    5. If you need to make an adjustment to the cutting units while backlapping, perform the following steps:

      1. Moving the Lower Mow/Raise lever rearward and press the Enable/Disable switch to DISABLE position.

      2. Shut off the engine and remove the key.

      3. Adjust to the cutting units.

      4. Repeat steps 1 through 3.

    6. Repeat steps 3 for the other cutting units that you want to backlap.

    Finishing Backlapping

    1. Moving the Lower Mow/Raise lever rearward and press the Enable/Disable switch to DISABLE position.

    2. Shut off the engine and remove the key.

    3. Move the backlap levers to the F (mow) position (Figure 153).

      Important: If you do not change backlap lever to the F (mow) position after backlapping, the cutting units will not function properly.

    4. Check all fasteners for looseness; tighten them as necessary.

    5. Grease or oil all grease fittings and pivot points. Wipe up any excess lubricant.

    6. Lightly sand and use touch-up paint on painted areas that are scratched, chipped, or rusted. Repair any dents in the metal body.

    7. Service the battery and cables as follows; refer to Electrical System Safety:

      1. Remove the battery terminals from the battery posts.

      2. Clean the battery, terminals, and posts with a wire brush and baking-soda solution.

      3. Coat the cable terminals and battery posts with Grafo 112X skin-over grease (Toro Part No. 505-47) or petroleum jelly to prevent corrosion.

      4. Slowly charge the battery every 60 days for 24 hours to prevent lead sulfation of the battery.

    Preparing the Engine

    1. Drain the engine oil from the oil pan and install the drain plug.

    2. Remove and discard the oil filter. Install a new oil filter.

    3. Fill the engine with specified motor oil.

    4. Start the engine and run it at idle speed for approximately 2 minutes.

    5. Shut off the engine and remove the key.

    6. Flush the fuel tank with fresh, clean fuel.

    7. Secure all fuel-system fittings.

    8. Thoroughly clean and service the air-cleaner assembly.
