Training
Read the instructions carefully. Be familiar with the controls and the proper use of the equipment. Learn how
to stop the mower quickly in an emergency.
Never allow children or people unfamiliar with these instructions to use the mower. Local regulations may
restrict the age of the operator.
Never mow while people, especially children, or pets are nearby.
Keep in mind that the operator or user is responsible for accidents or hazards occurring to other people or
their property.
Do not carry passengers.
All drivers should seek and obtain professional and practical instruction. Such instruction should
emphasise:
The need for care and concentration when working with this machine.
The need to slow down when making tight turning manoeuvres. Failure to take adequate care can affect
stability leading to loss of control of the machine particularly when operating in transport mode.
Control of a ride-on-machine sliding on a slope will not be regained by application of the parking brake.
The main reasons for loss of control are:
- Insufcient wheel grip.
- Being driven too fast.
- Inadequate braking.
- The type of machine is unsuitable for the task.
- Lack of awareness of the effect of ground conditions, especially slopes.
- Incorrect load distribution.
READ THIS MANUAL BEFORE USING THE T4240 MOWER, IT IS
ESSENTIAL THAT OPERATORS STUDY IT FOR THEIR OWN SAFETY.
THE FOLLOWING PRECAUTIONS MUST BE TAKEN TO HELP PREVENT
ACCIDENTS. A CAREFUL OPERATOR WHO USES COMMON SENSE IS THE
SAFEST OPERATOR.
SAFETY PRECAUTIONS
This manual should be regarded as part of the machine, as it gives essential
information regarding machine safety, operation, maintenance and specications.

1.8 1.8
Preparation
Check that the machine complies with all applicable regulations, including those in force when used on the
public highway.
While mowing, always wear substantial footwear and long trousers. Do not operate the equipment when
barefoot or wearing open sandals. Eye protection should be worn.
Thoroughly inspect the area where the equipment is to be used and remove all objects which can be thrown
by the machine.
Never operate the machine without rst checking that the operator platform latching mechanism is fully
engaged and in good working order, refer to OPERATOR PLATFORM LATCHING MECHANISM.
Ensure that the cutterheads are fully raised with the latches and safety locks engaged in position before
transporting the mower.
Replace faulty silencers.
Check the condition of the tyres and ensure that they are inated to the correct pressures, refer to
SPECIFICATIONS. This is particularly important if the machine is to be taken on the public highway.
Check that the mower is in good working order, paying particular attention to the brakes and steering. Also
ensure that the forward/reverse speed control pedals move freely to neutral when released.
Before use, always visually inspect to see that the blades, blade bolts and cutting cylinders are not worn or
damaged. Replace worn or damaged components.
Check the mower hydraulic system, particularly the hydraulic hoses, ttings and hose supports. Worn,
crushed or damaged hoses can burst, with risks to health and damage to the machine and surrounding turf
areas.
After refuelling and adding oil to the hydraulic oil tank ensure that the caps are replaced securely.
Check that all linkages, connections and pivot nuts are secure and that wheel nuts are torqued correctly,
refer to SPECIFICATIONS.
Before operating the machine ensure that there are no foreign objects or liquids on the platform or
pedals - ALWAYS KEEP THE OPERATOR PLATFORM CLEAN/CLEAR.
Always make sure that the folding R.O.P.S is secured in its vertical operating position before use.
SAFETY PRECAUTIONS

1.9 1.9
Operation
Do not operate the engine in a conned space where dangerous carbon monoxide fumes can collect.
Mow only in daylight or in good articial light.
Before attempting to start the engine, engage the parking brake, disengage the cutterhead drive system and
ensure that the forward/reverse speed controls are in the neutral position.
Never operate the machine without rst checking that the operator platform latching mechanism is fully
engaged and in good working order, refer to OPERATOR PLATFORM LATCHING MECHANISM.
Stored energy devices are charged when the outer wing units are in transport position. Always operate the
relevant lift controls to provide hydraulic support for the wing units suspensions before attempting to release
the transport latches.
Slopes
Do not use on a slope of more than 16 degrees. Care should be taken when using the mower on any slope
where ground conditions are such that there may be a risk of the mower rolling over. The requirements of
89/355/EEC, as amended by 95/63/EEC ‘Provision and Use of Work Equipment Directive’ should be
considered.
Stability angles given are maximum gures for a machine equipped with a R.O.P.S and are for guidance only.
Particular conditions such as wet grass or uneven ground may not permit safe operation on the slope limits
stated.
Remember there is no such thing as a ‘safe’ slope. Travel on grass slopes requires particular care. To guard
against overturning or loss of traction when travelling or mowing on a slope:
- Exercise extreme care when changing direction on a slope.
- Do not stop or start suddenly.
- Engage drive slowly.
- Keep machine speed low.
- Avoid tight turns.
- Stay alert for humps, hollows and other hidden hazards.
- Keep away from sharp inclines and steep drops.
- A thorough risk assessment should be carried out by a competent
person before travelling or mowing on a slope.
Never park on a slope.

Operation continued
Watch out for trafc when crossing or near roadways.
Use extreme caution when reversing.
Disengage the cutterhead drive system before crossing surfaces other than grass.
When using the machine, never direct discharge of material towards bystanders or allow anyone near the
machine while in operation.
Never operate the mower with defective guards, shields or without safety protective devices in place and in
good working order.
Do not change the engine governor settings or overspeed the engine. Operating an engine at excessive speed
may increase the risk of personal injury.
Before leaving the operator’s position:
- Disengage the drive to the cutterheads.
- Lift cutterheads to the transport position and securely lock the safety latches
or alternatively lower cutterheads to the ground.
- Ensure the transmission is in neutral and engage the parking brake.
- Stop the engine and remove the ignition key.
Engage the parking brake, disengage the drive to the cutterheads, stop the engine and remove ignition key:
- Before releasing blockages.
- Before checking, cleaning or working on the mower.
- After striking a foreign object. Inspect the mower for damage and make
repairs before restarting and operating the equipment.
- If the machine starts to vibrate abnormally (check immediately).
- Before refuelling.
- Before making cutterhead adjustments.
Disengage the drive to the cutterheads when transporting or not in use.
Never work on the mower when the engine is running.
Always keep feet and hands well away from the cutting cylinders when making adjustments.
Never operate the mower without rst checking that the operator platform is securely latched.
Always wear the seat belt when the folding R.O.P.S is in its vertical operating position.
Never wear the seat belt when the folding R.O.P.S is NOT in its vertical operating position.
Pay particular attention when operating due to the additional weight towards the front of the machine.
