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 the trailed mower sliding on a slope will not be regained by application of the brakes.
The main reasons for loss of control are:
- Insufcient 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 hitching and load distribution.
Never attempt to disconnect any part of the hydraulic system before de-pressurisation. This may be achieved
by lowering all cutterheads to the ground, turning off the tractor engine and disconnecting the PTO shaft.
READ THIS MANUAL BEFORE USING THE TRAILED GANG 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
1.8 1.8
Preparation
Check that the machine complies with all applicable regulations, including those in force when used on the
public highway. Check that the lights are in full working order and function correctly from the tractor.
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.
Before using, always visually inspect to see that the blades, blade bolts and cutter assembly are not worn or
damaged. Replace worn or damaged blades and bolts in sets to preserve balance.
On multi-bladed machines, take care as rotating one blade can cause other blades to rotate.
Ensure that the cutterheads are fully raised with the transport latches and safety locks engaged in position, and
that the PTO drive is disengaged and correctly stowed when disconnected before transporting the mower.
When transporting the mower with the PTO shaft assembly disconnected from the tractor PTO drive, the PTO
shaft assembly must be stowed securely to the mower chassis or tractor.
Check that the PTO shaft is fully engaged to the drive, driven shafts and that the guard safety chains are
secure.
Check the condition of the tyres and ensure that they are inated 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, drawbar, tyres and
lights. Check that all safety guards are in position and that the tractor complies with all applicable regulations
including those in force when used on a public highway.
Ensure that the automatic breakaway cable is secured correctly between the tractor and the machine brake
operating system.
Replace a broken, frayed or damaged breakaway cable.
Ensure that the parking brake operates correctly through its full travel without interference.
Ensure that the brakes are kept clean and adjusted regularly.
Ensure that the brake coupling mechanism is mounted securely in position, is correctly adjusted and
maintained, and operates through its full working travel without interference.
Replace the towing unit if the sliding mechanism or towing eye is excessively worn.
In the event of a breakaway cable being activated ensure that there is no interference on the brake coupling
mechanism.
Replace damaged or worn brake coupling mechanism components with the correct Toro service parts.
Never make an unauthorised modication to any part of the machine or brake coupling mechanism.
Ensure that the hydraulic brake actuating system operates through its full working travel without interference.
SAFETY PRECAUTIONS
1.9 1.9
Preparation continued
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.
Electric lift only:
Check the mower electrical system, particularly the condition of the umbilical cable and electrical connec-
tions between the tractor and the mower. Ensure that the system is in full working order and that the electrical
emergency stop system is fully operational.
Operation
Do not operate the engine in a conned space where dangerous carbon monoxide fumes can collect.
Mow only in daylight or in good articial light.
Never start the tractor engine with the PTO engaged.
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.
Use care when towing:
- Use only approved drawbar hitch points.
- Do not turn sharply.
- Use extreme caution when reversing.
Watch out for trafc when crossing or near roadways.
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.
Take care whilst manoeuvring in tight turns n forward and reverse gear to avoid contact between the mower
and the tractor.
SAFETY PRECAUTIONS

Operation continued
Disengage the PTO drive, change into neutral, set the tractor parking brake, stop the engine and remove
ignition key. Block the mower suddenly and operate the mower handbrake before performing any service or
maintenance procedure:
- 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.
- Before disconnecting the machine and the PTO from the tractor.
Always disengage the PTO drive when transporting or not in use.
Never work on the mower when the tractor engine is running.
Always keep feet and hands well away from the cutting cylinders when making adjustments.
Slopes
Do not use on a slope of more than 15 degrees when in use or 10 degrees with cutterheads raised. 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 and are for guidance only. Particular conditions
such as wet grass or uneven ground may not permit safe operation on the slope limits stated.
The slope angle may be reduced if the stability angle of the towing tractor is less than that of the mower.
Ground conditions affect traction. Particular conditions may not permit safe operation on the slope limit
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 clutch slowly. Always keep the tractor in gear, especially when travelling downhill.
- 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.
