  • 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

83 L (22 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 if you wish for more information on biodiesel.

Adding Fuel

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

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

    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; 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.

    Machines with a Foldable Roll Bar

    • Always use the seat belt with the roll bar in the raised position.

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

    • Lower a folding roll bar temporarily only when necessary. Do not wear the seat belt when the roll bar is folded down.

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

    • Check the area that you will be mowing and never fold down a folding roll bar in areas where there are slopes, drop-offs, or water.

    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.

    Fuel Gauge

    Use the fuel gauge (Figure 52) at the top of the tank to determine the fuel level.

    g368967

    Using the Engine-Speed Switch

    The engine-speed switch has 2 modes to change the engine speed.

    g370600
    • Momentarily tapping the switch increases or decreases the engine speed in 100-rpm increments.

    • Pressing and holding the switch down moves the engine speed directly to high or low idle, depending on which side of the switch you press.

    Starting the Engine

    Important: Bleed the fuel system if any of the following situations have occurred:

    • The engine has shut off because the machine ran out of fuel.

    • Maintenance was performed on the fuel system components.

      g370687
    4. Press the traction pedal to drive the machine.

      Important: Be careful when driving between objects so that 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 a rollover.

    Adjusting the Turf-Compensation Spring

    The turf-compensation spring (Figure 59) 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 59).

      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 59.

      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 Cutting-Unit 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).

    Note: To remove all counterbalance force, position the long leg of the torsion spring below the capscrew, washer, spacer, and locknut.

    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. Insert a tube or similar object over the long leg of the spring, and lift the spring leg to relieve pressure on the spacer (Figure 60).

      Note: Have another person help by lifting and lowering the spring leg.

      g370761
    3. While holding the spring, remove the bolt, washer, and locknut from the lift plate (Figure 60).

    4. Align the spring leg above the desired hole location.

    5. Install the capscrew, washer, spacer, and locknut at the hole location.

    6. Slowly lower the spring leg onto the spacer.

    7. Repeat the steps through 5 at the rear cutting unit-lift arm.

    Adjusting the Cutting Unit-Turnaround Height

    • Replace worn or damaged parts for safety.

    • Ensure that the seat belt and mountings are in safe working order.

    • Wear the seat belt when the roll bar is raised and no seat belt when the roll bar is lowered.

    You can fold the roll bar down to allow access into areas with restricted height.

    Warning

    The machine does not have a rollover protection system (ROPS) when the roll bar is folded down and should not be considered a ROPS.

    Do not wear a seatbelt when the roll bar is lowered.

    Warning

    When lowering and raising the roll bar, your fingers may get pinched between the machine and the roll bar.

    Use caution when lowering and raising the roll bar to prevent your fingers from getting pinched between the machine and the roll bar.

    Warning

    The roll bar is an integral safety device. It does not protect you from injury or even death from a rollover unless it is secured in the raised position and you are wearing the seat belt.

    • Keep the roll bar in the raise position whenever you operate the machine.

    • Lower the roll bar temporarily only when necessary, then secure it in the raised position as soon as possible before continuing operation.

    Important: The roll bar is an integral safety device. Keep the roll bar in the raised position when operating the mower. Lower the roll bar temporarily only when absolutely necessary.

    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. Remove the lynch pins that secure the roll-bar pins at each side of the roll bar (Figure 62).

    6. Secure the roll-bar pins to the brackets and lower roll-bar tubes with the lynch pins.

    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.

    Types of Diesel Particulate Filter Regeneration

    Types of diesel particulate filter regeneration that are performed while the machine is operating:

    Type of RegenerationConditions that cause DPF regenerationDPF description of operation
    PassiveOccurs during normal operation of the machine at high-engine speed or high-engine load• The InfoCenter does not display an icon indicating passive regeneration.
    • During passive regeneration, the DPF processes high-heat exhaust gasses, oxidizing harmful emissions, and burning soot to ash.
    Refer to Passive DPF Regeneration.
    AssistOccurs because of low-engine speed, low-engine load, or after the computer detects the DPF is becoming obstructed with soot• The InfoCenter does not display an icon indicating assist regeneration.
    • During assist regeneration, the engine computer adjusts the engine settings to raise the exhaust temperature.
    Refer to Assist DPF Regeneration.
    ResetOccurs every 100 hours• When the high exhaust-temperature icon Graphic is displayed in the InfoCenter, a regeneration is in progress.
    Also occurs after assist regeneration only if the computer detects that assist regeneration did not sufficiently reduce the soot level
     • During reset regeneration, the engine computer adjusts the engine settings to raise the exhaust temperature.
    Refer to Reset Regeneration.

    Types of diesel particulate filter regeneration that require you to park the machine:

    Type of RegenerationConditions that cause DPF regenerationDPF description of operation
    ParkedOccurs because the computer detects back pressure in the DPF due to soot buildup• When the reset-standby/parked or recovery regeneration icon Graphic or ADVISORY #188 displays in the InfoCenter, a regeneration is requested.
    Also occurs because the operator initiates a parked regeneration
    May occur because you set the InfoCenter to inhibit reset regeneration and continued operating the machine, adding more soot when the DPF already needs a reset regeneration• Perform the parked regeneration as soon as possible to avoid needing a recovery regeneration.
    May result from using the incorrect fuel or engine oil• A parked regeneration requires 30 to 60 minutes to complete.
     • You must have at least a 1/4 tank of fuel in the tank.
    • You must park the machine to perform a parked regeneration.
    Refer to Parked or Recovery Regeneration.
    RecoveryOccurs because the operator ignored requests for a parked regeneration and continued operating the machine, adding more soot to the DPF• When the reset-standby/parked or recovery regeneration icon Graphic or ADVISORY #190 displays in the InfoCenter, a recovery regeneration is requested.
    • A recovery regeneration requires up to 3 hours to complete.
    • You must have at least a 1/2 tank of fuel in the machine.
    • You must park the machine to perform a recovery regeneration.
    Refer to Parked or Recovery Regeneration.
