Before starting the machine each day, perform the Each Use/Daily procedures listed in .

Filling the Fuel Tank

Fuel Tank Capacity

60 L (15.9 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.

EN 590European Union
ISO 8217 DMXInternational
JIS K2204 Grade No. 2Japan
KSM-2610Korea
  • 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.

      • 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.

    Understanding the Operator Presence Controls

    Caution

    If 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.

    Important: Do not operate the machine if the operator presence controls are damaged or worn. Always replace damaged or worn parts, and check that operator presence controls function correctly before operating the machine.

    Engine Start Interlock

    You can start the engine only when the forward/reverse travel pedal is in the NEUTRAL position, the cutting-unit-drive switch is in the OFF position, and the parking brake is engaged.

    Note: You can start the engine only when the cutting-unit-drive switch is in the OFF position.

    Engine Run Interlock

    Once you start the engine, you must sit in the operator’s seat to run the engine while the parking brake is disengaged.

    The engine shuts off if you leave the operator’s seat without first engaging the parking brake.

    Cutting Unit Drive Interlock

    You must sit in the operator’s seat to run the cutting units. If you raise off the seat for more than a second, a switch activates and the drive to the cutting units disengages.

    To reset the cutting units, sit in the seat, move the cutting-unit-drive switch to the OFF position, and then move the switch to the ON position.

    Note: If you briefly raise off the seat during normal work, drive to the cutting units is not affected.

    Adjusting the Roll Bar

    Warning

    To avoid injury or death from rollover, keep the roll bar in the raised locked position and use the seat belt.

    Ensure that the seat is secured with the seat latch.

    Warning

    There is no rollover protection when the roll bar is in the down position.

    • Do not operate the machine on uneven ground or on a hill side with the roll bar in the down position.

    • Lower the roll bar only when absolutely necessary.

    • Do not wear the seat belt when the roll bar is in the down position.

    • Drive slowly and carefully.

    Flail Cutting Unit General Information

    It is important to keep the flail blades sharp and in good condition to ensure good cutting performance, minimum power consumption, and a good quality of cut.

    The flail head is a fine cut flail and should only be used for maintaining grass. Its recommended that a maximum of 1/3 of the total grass length is removed when cut.

    The scraper wires are fitted to remove debris from the roller, in dry conditions these may not be required and its recommended they are removed. In damp wet conditions ensure that scraper wires do not get plugged with debris.

    The cutting unit floats and can pivot laterally to follow ground contours.

    The cutting units are designed to be operated at full engine rpm. Forward speed should be adjusted depending on grass conditions and to not overload the power units or the heads. The lower the forward speed the higher the quality of cut and after cut appearance.

    Adjusting the Height of Cut

    Note: The height of cut is gauged by the rear roller. Blade wear, worn cutting unit pivots, bent/damaged cutting unit pins, and bent/damaged arms can affect the height-of-cut setting.

    1. Turn the adjusting-nut assembly on both ends clockwise to decrease the height of cut or counter-clockwise to increase the height of cut (Figure 26).

      g330034

      Important: Do not attempt to unlock the nut assemblies.

    2. Ensure that all cutting units are set at the same height of cut by referring to the indicator rings (Figure 27).

      g034596

      Note: Refer to Figure 28 for the height-of-cut settings.

      g034925

    Controlling the Position of the Individual Cutting Units

    Lowering the Cutting Unit

    1. Press the cutting-unit-drive switch to the cut position.

    2. Press the lift-control switch forward and release.

      Note: The cutting unit engages when it is approximately 150 mm (6 inches) above ground level. The cutting unit is in ‘float’ mode, and follows the ground contours.

      Note: The lift-control switch automatically returns to the (NEUTRAL) position when you release it.

      g287651

    Raising the Cutting Unit

    1. Pull and hold the lift-control switch.

    2. Release the lift-control switches when the cutting units are at the needed height.

    Note: The lift-control switches automatically return to the (NEUTRAL) position when you release it and the cutting unit arms hydraulically lock into position.

    Cutting Unit Limited-Lift Position

    Limiting Cutting Unit Lift When Driving Forward

    Note: The limited lift function for driving forward is enabled by default.

    • While driving forward, momentarily pull the lift-control switch(s).

      Note: The cutting unit(s) shuts off and it raises approximately 150 mm (6 inches) above ground level.

    • The limited lift function shuts off when the cutting unit is lowered and running.

    Limiting Cutting Unit Lift When Driving Backward

    Note: You must enable the limited-lift function in the InfoCenter to automatically lift the cutting units when driving backward.

    • When the limited-lift function is enabled, driving the machine backward causes all cutting units raise to the limited-lift position.

      Note: The cutting unit(s) raises approximately 150 mm (6 inches) above ground level.

      Important: The cutting units continue to run while using limited lift and driving the machine backward.

    • Driving the machine forward again causes the cutting unit lower to the float position.

    Using the Cutting-Unit Turnaround Feature

    Note: You must enable the turnaround feature for the center lift-control switch in the settings menu of the InfoCenter.

    • Momentarily pull the lift-control switch for the center cutting unit to raise all cutting units to the limited lift position.

    • Momentarily push down the lift-control switch for the center cutting unit to lower all cutting units to the float position.

    Adjusting the Cutting Unit Auto-Limited Lift

    Note: You enable the cutting-unit Auto Limited Lift feature in the settings menu of the InfoCenter.

    • Manual limited lift uses the 3 lift-control switches, and is always available regardless of auto-limited lift setting in the InfoCenter.

    • When cutting-unit Auto Limited Lift is enabled, driving the machine in reverse causes the cutting units to automatically raise to the limited-lift position.

    • The cutting units return to the floating position when driving the machine forward.

    To raise the cutting units to the limited-lift position, momentarily pull the lift-control switches.

    Note: The cutting-unit drives disengage immediately, and the cutting units raise to approximately 150 mm (6 inches) above ground level.

    Auto-limited lift operates with the cutting units lowered and rotating.

    The cutting unit drive switch must be set to the ON position (Figure 30). Operate the lift-control switch(s) in a downward direction. The cutting units run when the cutting units are approximately 150 mm (6 inches) above ground level.

    Adjusting the Weight Transfer/Traction Assistance

    A variable hydraulic weight transfer system provides improved tire grip with the grass surface—traction assistance.

    Hydraulic pressure from the cutting-unit lift system provides a lifting force that reduces the weight of the cutting units on the ground and transfers the weight downward to the tires. This action is known as weight transfer.

    Note: Adjust the amount of weight transfer to suit operating conditions.

    1. Open the hood.

      g292364g292365
    2. At the right side of the machine, loosen the lock wheel of the weight transfer manifold 1/2 turn counterclockwise while holding the hand wheel steady (Figure 31).

    3. Rotate the weight transfer hand wheel (Figure 31) as follows:

      • counterclockwise to reduce weight transfer

      • clockwise to increase weight transfer

      Note: The recommended setting for the weight transfer/traction assistance is to increase the weight transfer until the cutting units start to lift, then rotate the hand wheel 1/2 turn counterclockwise.

    4. Tighten the lock wheel (Figure 31).

    Clearing the Cutting Units

    Warning

    Never attempt to rotate the cutting units by hand. Residual pressure in the hydraulic system could cause the cutting unit(s) to rotate suddenly when you release the blockage, which may cause serious injury.

    • Always wear protective gloves and use a suitable strong wooden instrument.

    • Ensure that the wooden instrument fits in the flail rotor and is long enough to provide leverage to release the blockage.

    1. Park the machine on a level surface.

    2. Move the traction pedal to the NEUTRAL position, engage the parking brake, and shut off the cutting units.

    3. Lower the cutting units to the ground or securely lock them in the transport positions.

    4. Shut off the engine, remove the key, and wait for all moving parts to stop.

    5. Release all stored energy devices.

    6. Check that all moving parts are stationary.

    7. Using a suitable strong wooden instrument, remove the blockage. Ensure that the wooden instrument is properly supported in the cutting unit and avoid using excessive force to prevent damage.

    8. Remove the wooden instrument from the cutting unit before starting the engine.

    9. Repair or adjust the cutting unit if required.

    Operating Tips

    Becoming Familiar 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 unit, and engage and disengage them. When you feel familiar with the machine, practice operating it up and down slopes.

    Mowing Grass

    To maintain the high quality of cut, keep the rotational speed of the cutting units as high as possible. This requires high engine speed.

    Cutting performance is best when cutting against the lie of the grass. To take advantage this effect, alternate the mowing direction between cuts.

    Take care to not leave uncut strips of grass at the overlap at points between adjacent cutting units by avoiding tight turns.

    Maximizing the Quality of Cut

    The quality of cut deteriorates when the forward speed is too fast. Always balance the quality of cut with the required cutting rate, and set the forward speed accordingly.

    Maximizing Engine Efficiency

    Do not let the engine labor. If you notice that the engine starts to labor, reduce the forward speed or increase the height of cut. Ensure that the cutting unit blades are sharp.

    Driving the Machine in Transport Mode

    Important: Take care when driving the machine over obstacles such as roadside curbs.Always travel at slow speed over obstacles to prevent damage to the tires, wheels, and steering system. Ensure that the tires are inflated to the recommended pressures.

    Always disengage the cutting unit drive when driving the machine across areas with no grass. Be careful when driving between objects so that you do not accidentally damage the machine or the cutting units.

    Using the Rear Roller Scrapers

    For optimum grass discharge, remove the rear roller scrapers where conditions allow.

    If mud and grass start to build up on the rollers, install the scrapers. When installing the scraper wires, tension them correctly.
