Performing Daily Maintenance

Maintenance Service IntervalMaintenance Procedure
Before each use or daily
  • Inspect the seat belt(s) for wear, cuts, and other damage. Replace the seat belt(s) if any component does not operate properly.
  • Before starting the machine each day, perform the Each Use/Daily procedures listed in .

    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, shut off the engine, engage the parking brake, and remove the key.

    • 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.

    Shutting Off the Engine

    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.

    Burnishing the Brakes

    To ensure optimum performance of the parking-brake system, burnish (break in) the brakes before use. Set the forward traction speed to 6.4 km/h (4 mph) to match the reverse traction speed (all 8 spacers moved to the top of the mow-speed control). With the engine at high idle, proceed forward with the mow-speed-control stop engaged and ride the brake for 15 seconds. Proceed backward at full reverse speed and ride the brake for 15 seconds. Repeat this 5 times, waiting 1 minute between each forward and reverse cycle to avoid overheating the brakes; refer to Adjusting the Parking Brakes.

    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.

    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

    g213867
    The computer de-rates the engine power to 50%.Perform a recovery regeneration as soon as possible; refer to Performing a 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.

    Operating Tips

    Becoming Familiarized with the Machine

    Before mowing grass, practice operating the machine in an open area. Start and shut off the engine. Operate in forward and reverse. Lower and raise the cutting units and engage and disengage the reels. When you feel familiar with the machine, practice operating up and down slopes at different speeds.

    Understanding the Warning System

    If a warning light comes on during operation, stop the machine immediately and correct the problem before continuing operation. Serious damage could occur if you operate the machine with a malfunction.

    Mowing

    Start the engine and move the engine-speed switch to the FAST position. Move the Enable/Disable switch to the ENABLE position and use the Lower Mow/Raise lever to control the cutting units (the front cutting units are timed to lower before the rear cutting units). To move forward and cut grass, press the traction pedal forward.

    Transporting the Machine

    Move the Enable/Disable switch to the DISABLE position and raise the cutting units to the TRANSPORT position. Move the Mow/Transport lever to the TRANSPORT position. Be careful when driving between objects so you do not accidentally damage the machine or cutting units. Use extra care when operating the machine on slopes. Drive slowly and avoid sharp turns on slopes to prevent rollovers. Lower the cutting units when going downhill for steering control.

    After Operation

    • Seek immediate medical attention if fluid is injected into skin. Injected fluid must be surgically removed within a few hours by a doctor.

    • Ensure that all hydraulic-fluid hoses and lines are in good condition and all hydraulic connections and fittings are tight before applying pressure to the hydraulic system.

    • Keep your body and hands away from pinhole leaks or nozzles that eject high-pressure hydraulic fluid.

    • Use cardboard or paper to find hydraulic leaks.

    • Safely relieve all pressure in the hydraulic system before performing any work on the hydraulic system.

    Hydraulic Fluid Specifications

    The reservoir is filled at the factory with high-quality hydraulic fluid. Check the level of the hydraulic fluid before you first start the engine and daily thereafter; refer to Checking the Hydraulic Fluid.

    Recommended hydraulic fluid: Toro PX Extended Life Hydraulic Fluid; available in 19 L (5 US gallon) pails or 208 L (55 US gallon) drums.

    Note: A machine using the recommended replacement fluid requires less frequent fluid and filter changes.

    Alternative hydraulic fluids: If Toro PX Extended Life Hydraulic Fluid is not available, you may use another conventional, petroleum-based hydraulic fluid having specifications that fall within the listed range for all the following material properties and that it meets industry standards. Do not use synthetic fluid. Consult with your lubricant distributor to identify a satisfactory product.

    Note: Toro does not assume responsibility for damage caused by improper substitutions, so use products only from reputable manufacturers who will stand behind their recommendation.

    Cutting Unit System Maintenance

    Blade Safety

    A worn or damaged blade or bedknife can break, and a piece could be thrown toward you or bystanders, resulting in serious personal injury or death.

    • Inspect the blades and bedknives periodically for excessive wear or damage.

    • Use care when checking the blades. Wear gloves and use caution when servicing them. Only replace or backlap the blades and bedknives; never straighten or weld them.

    • On machines with multiple cutting units, take care when rotating a cutting unit; it can cause the reels in the other cutting units to rotate.

    Checking the Reel-to-Bedknife Contact

    Maintenance Service IntervalMaintenance Procedure
    Before each use or daily
  • Check the reel-to-bedknife contact.
  • Each day before operating, check reel-to-bedknife contact, regardless if the quality of cut had previously been acceptable. There must be light contact across the full length of the reel and the bedknife (refer to Adjusting the Reel to Bedknife in the Operator's Manual for the cutting units).

    Backlapping the Cutting Units

    Warning

    Contact with the reels or other moving parts can result in personal injury.

    • Keep fingers, hands, and clothing away from the reels or other moving parts.

    • Never attempt to turn the reels by hand or foot while the engine is running.

    Note: When backlapping, the front units all operate together, and the rear units operate together.

    1. Park the machine on a level surface, lower the cutting units, shut off the engine, engage the parking brake, and move the Enable/Disable switch to the DISABLE position.

    2. Unlock and raise the seat to expose the backlap levers (Figure 105).

    3. Make initial reel-to-bedknife adjustments appropriate for backlapping on all cutting units that are to be backlapped; refer to the Operator's Manual for the cutting units.

    4. Start the engine and run at low idle speed.

      Danger

      Changing the engine speed while backlapping may cause the reels to stall.

      • Never change the engine speed while backlapping.

      • Backlap only at low engine-idle speed.

    5. Select either front, rear, or both backlap levers to determine which units to backlap (Figure 105).

      Danger

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

    6. With the Mow/Transport lever in the MOW position, move the Enable/Disable switch to the ENABLE position. Move the Lower Mow/Lift control forward to start the backlapping operation on the designated reels.

    7. Apply lapping compound with a long-handled brush.

      Important: Never use a short-handled brush.

    8. 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.

    9. To adjust the cutting units while backlapping, turn the reels off by moving the Lower Mow/Raise lever rearward; the Enable/Disable switch to the DISABLE position, and shut off the engine.

      After completing adjustments, repeat steps 4 through 8.

      g021209
    10. Repeat the procedure for all cutting units you want to backlap.

    11. When finished, return the backlap levers to the MOW position, lower the seat, and wash all lapping compound off the cutting units.

      Note: Adjust the cutting-unit reel to bedknife as needed. Adjust the cutting-unit reel speed to the desired mowing setting.

      Important: If the backlap switch is not returned to the OFF position after backlapping, the cutting units do not raise or function properly.

      Note: For a better cutting edge, run a file across the front face of the bedknife after lapping. This removes any burrs or rough edges that may have built up on the cutting edge.

    Cleaning

    Washing the Machine
