Braking System

Parking Brake

Move the parking-brake switch to the forward position by pressing the smaller locking button and moving the switch forward to engage the parking brake (Figure 7).

Note: Do not operate the mower with the parking brake engaged and do not engage the parking brake while the mower is moving.

This light illuminates when the parking brake is engaged and the ignition key is turned to position I.

Warning

The parking brake operates on the front wheels only.

Do not park the machine on a slope.

g034880

Service Brake

Service braking is achieved by the hydraulic transmission system. When the forward or reverse travel pedals are released or the engine speed is reduced, service braking becomes effective and travel speed is automatically reduced. To increase the braking effect, push the transmission pedal into the NEUTRAL position. Service braking is effective on the front wheels only.

Danger

The service braking system does not hold the mower at a standstill.

Always ensure that the parking brake is engaged to park the mower at a standstill.

Emergency Brake

In the event of service brake failure, turn the ignition off to bring the mower to a standstill.

Throttle Control

Operate the throttle control in a forward direction to increase the engine speed. Operate the throttle control in a rearward direction to reduce engine speed (Figure 8).

Note: The engine speed dictates the speed of the other functions, i.e., travel, flail-rotor rotation speed, and cutting unit lift speed.

g035354

Travel

Forward travel: Press the forward travel pedal to increase forward travel speed. Release the pedal to reduce speed (Figure 9).

Reverse travel: Press the reverse travel pedal to increase reverse travel speed. Release the pedal to reduce speed (Figure 9).

Stop (Neutral): To stop the machine, use 1 of the following procedures:

  • Reduce your foot pressure on the traction pedal and allow it to return to the neutral position. The machine dynamically brakes to a smooth stop.

  • Tap or hold the reverse pedal briefly. This stops the machine faster than dynamic braking.

g014420

Differential Lock

Warning

The turning radius increases when the differential lock is engaged. Using the differential lock at high speed may lead to loss of control and cause serious injury and/or property damage.

Do not use the differential lock at high speed.

Use the differential lock to prevent excessive wheel spin when the drive wheels lose traction. The differential lock operates in both forward and reverse. You can lock the differential while the machine is traveling slowly. Engine power demand increases when the differential is locked. Prevent excessive power requirements by using the differential lock only at low speed.

To lock the differential, press the differential-lock switch.

To unlock the differential, release the differential-lock switch.

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

    • Shut off the engine, 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 engine quickly.

    • Do not operate the machine without all guards and other safety protective devices in place and functioning properly on the machine.

    • 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.

    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

    45 L (11.9 US gallons)

    Fuel Specification

    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

    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 (Number 2-D) at temperatures above -7°C (20°F) and winter-grade diesel fuel (Number 1-D or Number 1-D/2-D blend) below -7°C (20°F). Using winter-grade fuel at lower temperatures provides a lower flash point and cold-flow characteristics, which will ease starting and reduce fuel-filter plugging.

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

    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 the area around the fuel-tank cap.

    3. Remove the cap from the fuel tank.

    4. Fill the tank until the level is to the bottom of the filler neck with fuel.

    5. Install fuel-tank cap tightly after filling tank.

      Note: If possible, fill the fuel tank after each use. This minimizes possible buildup of condensation inside the fuel tank.

    Understanding the Operator Presence Controls

    Note: The engine stops if the operator leaves the seat without engaging the parking brake.

    Engine Start Lockout: The engine can only be started 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. When these circumstances are satisfied, switches are activated permitting the engine to be started.

    Engine Run Interlock: Once the engine is started the operator must be seated before the parking brake is disengaged for the engine to continue to run.

    Cutting Unit Drive Lockout: The drive to the cutting units is only possible when the operator is seated. If the operator raises off the seat for a period of more than one second, a switch is activated and the drive to the cutting units is automatically disengaged. To engage the drive to the cutting units, the operator must return to the seat, then operate the cutting unit drive switch to the Off position before moving it back to the On position. If the operator rises off the seat for a brief moment during normal work, drive to the cutting units is not affected.

    The engine can only be started with the cutting unit drive switch in the Off position.

    Warning

    Do not operate the turf mower if the operator presence controls are malfunctioning in any way. Always replace damaged or worn parts and check that they function correctly before operating the machine.

    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 30).

      g034595

      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 31).

      g034596

      Note: Refer to Figure 32 for the height-of-cut settings.

      g034925

    Controlling the Position of the Individual Cutting Units

    The cutting units may be raised or lowered independently using the bank of 3 lift-control switches.

    1. To lower the cutting units, operate the lift-control switches in a downward direction and release.

      Note: The cutting-unit-drive switch must be on to do this, the flail rotor drive engages when the cutting units are approximately 150 mm (6 inches) above ground level. The cutting units are now in ‘float’ mode and follow the ground contours.

      g034915
    2. To raise the cutting units, operate the lift-control switches in an upward direction and hold in position 3. If the cutting-unit-drive switch is in the ON position the flail rotor drive disengages.

    3. Release the lift-control switches when the cutting units are at the required height.

      Note: The control switches automatically return to position 2 (NEUTRAL) and the arms are hydraulically locked into position.

    To raise the cutting units to the limited lift position: momentarily operate the switches in an upward direction.

    The flail rotor drive disengages immediately and the cutting units stop raising, approximately 150 mm (6 inches) above ground level.

    This operates with the cutting units lowered and rotating.

    Auto limited lift in reverse causes the cutting units to rise automatically to the limited lift position when reversing. They return to the floating position when returning to forward travel. The flail rotors continue to rotate during this operation.

    Using the Cutting Unit Auto-Limited Lift in Reverse

    To activate, press the auto-limited-lift switch to the ON position (Figure 34).

    To deactivate, press the auto-limited-lift switch to the OFF position (Figure 34).

    Manual limited lift using the 3 lift-control switches is always available regardless of the position of the auto switch.

    g034928

    Engaging the Cutting Unit Drive

    g034904

    The cutting unit drive can be engaged only when the operator is seated correctly, refer toChecking the Operator-Presence-Seat Switch.

    Cutting unit drive engagement: Press the top of the cutting-unit-drive switch to the on position (Figure 35).

    All cutting unit drives disengagement: Set the switch to the off position (Figure 35).

    To lower the cutting units: The cutting unit drive switch must be set to the on position. Operate the lift-control switch(s) in a downward direction. The machine drives when the cutting units are approximately 150 mm (6 inches) above ground level.

    Using Weight-Transfer/Traction Assistance

    A variable hydraulic weight transfer system is provided for improving tire grip with the grass surface—traction assistance.

    Hydraulic pressure in the cutting units lift system provides a lifting force which reduces the weight of the cutting units on the ground and transfers the weight as a downward force onto the tires of the machine. This action is known as weight transfer.

    To engage weight transfer: The amount of weight transfer can be varied to suit operating conditions by rotating the weight-transfer hand wheel (Figure 36) as follows:

    1. Release the valve locknut 1/2 turn counterclockwise and hold (Figure 36).

    2. Rotate the valve hand wheel (Figure 36) counterclockwise to reduce weight transfer or clockwise to increase weight transfer.

    3. Tighten the nut.

    Note: The recommended setting is to increase weight transfer until heads start to lift, then back off 1/2 turn, and lock.

    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 units and engage and disengage the cutting units. 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 Grass

    The rotational speed of the flail rotors should always be kept as high as possible in order to maintain the highest quality of cut. This in turn requires that the engine speed be kept as high as possible.

    Cutting performance is best when cutting against the lie of the grass. In order to take advantage of this fact, the operator should attempt to alternate the direction of mowing between cuts.

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

    Maximizing the Quality of Cut

    The quality of cut deteriorates if the forward speed is excessive. Always balance the quality of cut with the work rate required 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. Check to make sure that the flail blades are sharp.

    Driving the Machine in Transport Mode

    Always disengage the cutting unit drive when travelling across un-grassed areas. Be careful when driving between objects so that you do not accidentally damage the machine or the cutting units.

    Warning

    Take care when travelling over obstacles such as roadside curbs as such obstacles may allow the machine to rollover which may cause severe injury.

    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.

    Operating the Machine on Slopes

    Use extra care when operating the machine on slopes. Drive slowly and avoid sharp turns on slopes to prevent rollovers. Lower the cutting units for steering control when going downhill.

    Using the Rear Roller Scrapers

    It is generally wise to remove rear roller scrapers where conditions allow, as optimum grass discharge is achieved without them. Install the scrapers when conditions are such that mud and grass start to buildup on the rollers. When installing the scraper wires, ensure that they are correctly tensioned.

    After Operation

    After Operation Safety

    General Safety

    • Shut off the engine, 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.
