Braking System

Parking Brake

Move the parking brake switch to the rearward position by pressing the smaller locking button and moving the switch forward to engage the parking brake (Figure 3).

Note: Do not operate the machine with the parking brake engaged and do not engage the parking brake while the machine 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.

Service Brake

Service braking is achieved by the hydraulic transmission system. When the forward or reverse travel pedals are released or the engine speed 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.

Warning

The service braking system is not able to hold the mower at a standstill. Always ensure 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 stand still.

Warning

Take care when using the emergency braking. Remain seated and hold on to the steering wheel to prevent ejection from the mower caused by the front wheel brakes being applied suddenly when traveling.

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 3).

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

Travel Pedals

Forward travel: Press the forward travel pedal to increase forward travel speed. Release the pedal to reduce speed (Figure 4).

Reverse travel: Press the reverse travel pedal to increase reverse travel speed. Release the pedal to reduce speed (Figure 4).

Stop (Neutral): Release the forward or reverse travel pedal.

Work/Transport Mode

Select WORK mode when operating the machine in poor traction conditions when you need maximum tractive performance (Figure 3). Selecting WORK mode will enable the use of the differential lock.

Select TRANSPORT mode when operating the machine in good traction condition (i.e., when traveling on public highway or mowing large, level, open areas). Selecting TRANSPORT mode in these conditions will reduce transmission system wear and tear.

Note: The differential lock is not available for use when the TRANSPORT mode is selected.

Transport Latches

Always raise the cutting units to the transport position and secure with the transport latches and safety locks when traveling between work areas (Figure 5).

g014548

    Before Operation

    Before Operation Safety

    General Safety

    • Never allow children or untrained people to operate or service the machine. Local regulations may restrict the age of the operator. The owner is responsible for training all operators and mechanics.

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

    • Shut off the engine, remove the key (if equipped), 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

    70 L (18.5 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.

    2. Using a clean rag, clean 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 diesel fuel.

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

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

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

    1. To lower the cutting units, operate the lift-control levers in a downward direction and release (Figure 26).

      Note: The cylinder drive will engage when the cutting units are approximately 300 mm (11.8 inches) above ground level. The cutting units are now in ‘float’ mode and will follow the ground contours.

      Important: The lift-control levers must be locked in position 1 while moving. Do not mow with the lift control levers in position 2.

      g029259

      Note: The lift levers will control different cutting units depending on the lift configuration mode; refer to Dual Lift Configuration Control.

    2. To raise the cutting units, operate the lift-control levers in an upward direction and hold in position 3.

      Note: If the cutting unit drive switch is in the ON position, the cylinder drive will disengage when the cutting units are approximately 300 mm (11.8 inches) above ground level.

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

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

    To lower the cutting unit: Operate the lift-control lever in a downward direction. The cylinder will drive when the cutting units are approximately 300 mm (11.8 inches) above ground level.

    Using the 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 cutting units’ weight 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: You can vary the amount of weight transfer to suit operating conditions by rotating the weight transfer hand wheel as follows:

    1. Release the valve locknut 1/2 turn anti-clockwise and hold.

    2. Rotate the valve hand wheel.

      • Anti-clockwise to reduce weight transfer.

      • Clockwise to increase weight transfer.

    3. Tighten the nut.

    g029236

    Clearing Debris from the Cutting Units

    Warning

    Never attempt to rotate the cutting cylinders by hand.

    • There may be some residual pressure in the hydraulic system which could cause injury through sudden movement of the cylinder(s) when the blockage is released.

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

    • Ensure that the wooden instrument will fit between the blades and through the cylinder and is long enough to provide sufficient leverage to release the blockage.

    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. Disengage all drives.

    3. Check that all power sources are stopped.

    4. Release all stored energy devices.

    5. Check that all moving parts are stationary.

    6. Using a suitable strong wooden instrument, remove the blockage. Make sure that the wooden instrument is properly supported in the cylinder and avoid the use of excessive force to prevent damage.

    7. Ensure that the wooden instrument is removed from the cutting cylinder before starting the power source.

    8. 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 stop 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 cutting cylinders 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 will deteriorate 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 that the cutting cylinders are not in heavy contact with their bottom blades.

    Driving the Machine in Transport Mode

    Always disengage the cutting unit drive when traveling across un-grassed areas. Grass will lubricate the cutting edges whilst mowing. Excessive heat will build up if the cutting cylinders are run when not mowing and this will cause rapid wear to take place. For this reason it is also wise to reduce cutting speed when mowing lightly grassed areas or when the grass is dry. Be careful when driving between objects so that you do not accidentally damage the machine or the cutting units.

    Warning

    Take care when traveling 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.

    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 build up 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 (if equipped), 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.
