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.
The parking brake operates on the front wheels only. Do not park the machine on a slope.
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.
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.
In the event of service brake failure, turn the ignition off to bring the mower to a stand still.
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.
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.
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).

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.
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).
Do not engage the differential lock at high speed. The turning circle will increase with the differential lock engaged.
Engage the differential lock to increase tractive effort. Only engage the differential lock at slow speeds (Figure 4). It will operate while the machine is moving forward and reverse.
To engage the differential lock, press the differential lock pedal. To disengage the differential lock, release the differential lock pedal.
Note: The differential lock is effective only when WORK is selected.
Use the backstop lever to limit the movement of the forward pedal for accurate forward travel speed and to limit the clip rate required (Figure 4).
Move the lever forward to increase the travel speed setting and rearward to decrease it.
Note: This is not a cruise-control device. Releasing the forward travel pedal will allow it to return to neutral.
Always put the cutting unit drive switch in the OFF position when traveling between work areas.
Never operate the machine without first checking that the steering column adjuster mechanism is in good working order and that, once adjusted and locked, the steering wheel remains securely in position.

Before starting the machine each day, perform the Each Use/Daily procedures listed in .
70 L (18.5 US gallons)
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.
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.
Park the machine on a level surface.
Using a clean rag, clean area around the fuel-tank cap.
Remove the cap from the fuel tank.
Fill the tank until the level is to the bottom of the filler neck with diesel fuel.
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 owner/operator can prevent and is responsible for accidents that may cause personal injury or property damage.
Wear appropriate clothing, including eye protection; long trousers; 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.

Keep the ROPS in safe operating condition by thoroughly inspecting it periodically for damage and keeping all the mounting fasteners tight.
Replace a damaged ROPS. Do not repair or alter it.
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.
Slopes are a major factor related to loss of control and rollover accidents, which can result in severe injury or death. The operator is 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 and review the conditions in which you will operate the machine to determine whether you can operate it 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. Loss of traction to the drive wheels may result in sliding and a loss of braking and steering.
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 unit(s) lowered to the ground while operating on slopes. Raising the cutting unit(s) while operating on slopes can cause the machine to become unstable.
Use extreme caution with grass collection systems or other attachments. These can change the stability of the machine and cause a loss of control.

Note: This will ensure that the latch hooks clear the locking bar.
Fully lower the platform and move the locking latch handle toward the rear of the machine until the latch hooks fully engage the locking bar (Figure 23).
Install the padlock to secure the locking latch handle in place.
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: After starting the engine, you must be seated before releasing the parking brake for the engine to continue to run.
Cutting Cylinder Drive Lockout: The drive to the cutting cylinders is only possible when you are seated. If you raise off the seat for a period of more than 1 second, a switch activates and the drive to the cutting cylinders automatically disengages. To engage drive to the cutting cylinders, return to the seat, then operate the cutting unit drive switch to the OFF position before moving it back to the ON position. If you rise off the seat for a brief moment during normal work, drive to the cutting cylinders is not affected.
The engine can only be started with the cutting-unit drive switch in the OFF position.
Do not operate the turf machine 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.
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.

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:
Release the valve locknut 1/2 turn anti-clockwise and hold.
Rotate the valve hand wheel.
Anti-clockwise to reduce weight transfer.
Clockwise to increase weight transfer.
Tighten the nut.
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.
Park the machine on a level surface, lower the cutting units, engage the parking brake, shut off the engine, and remove the key.
Disengage all drives.
Check that all power sources are stopped.
Release all stored energy devices.
Check that all moving parts are stationary.
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.
Ensure that the wooden instrument is removed from the cutting cylinder before starting the power source.
Repair or adjust the cutting unit if required.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Clean grass and debris from the cutting units, drives, mufflers, cooling screens, and engine compartment to help prevent fires. Clean up oil or fuel spills.
Shut off the fuel while storing or transporting the machine.
Disengage the drive to the attachment whenever you are transporting or not using the machine.
Maintain and clean the seat belt(s) as necessary.
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 on other appliances.
Use full-width ramps for loading the machine onto a trailer or truck.
Tie the machine down securely.
Note: Support the machine with jack stands whenever you work under the machine.
Front—under the front arm mount.
Rear—rear strapping hook.
Apply the parking brake of the towing machine.
Chock the front wheels of the machine to prevent it from rolling away.
Connect a rigid tow bar between the towing eye on the machine and a suitable towing vehicle.
