1.25 OPERATING THE MOWER 1.25 Safety Notice WARNING: PREVENT ACCIDENTS - Before operating the mower it is essential that; The operator reads and understands this manual. The operator platform latching mechanism is fully engaged and in good working order, refer to OPERATOR PLATFORM LATCHING MECHANISM.
1.27 OPERATING THE MOWER 1.27 Braking System Parking brake engaged Parking brake: Move the parking brake lever to its rear position to engage the parking brake. Do not operate the mower with the parking brake engaged. WARNING: PREVENT ACCIDENTS - The parking brake operates on the front wheels only.
1.28 OPERATING THE MOWER 1.28 Transport Latches WARNING: PREVENT ACCIDENTS - ALWAYS raise the cutterheads to the transport position and secure with the transport latches and safety locks when travelling between work areas. Front cutterhead transport latches: Centre cutterhead transport latch: 1.
1.29 OPERATING THE MOWER 1.29 Speed Control Pedals The speed control pedal can be adjusted to provide two speed ranges. Securing the speed control cable through hole ‘A’ will provide 0-22 km/hr (0-14 mph) forward and 0-11 km/hr (0-7 mph) reverse. Securing the cable through hole ‘B’...
1.30 OPERATING THE MOWER 1.30 Operator Platform Latching Mechanism Cont’d Securing the platform: Lower the platform carefully. The gas spring will provide assistance. Move the locking latch handle towards the front of the mower (position A) as the platform nears the fully lowered position.
1.31 OPERATING THE MOWER 1.31 Folding the R.O.P.S The R.O.P.S frame may be folded down to allow access into areas of restricted height. WARNING: PREVENT ACCIDENTS - While the R.O.P.S frame is folded down it does not provide any protection in the event of a roll-over and should not be considered as a Roll Over Protective Structure.
1.32 OPERATING THE MOWER 1.32 Operator Seat WARNING: PREVENT ACCIDENTS - Before operating the mower ensure that the operator seat mechanisms are in good working order and that the seat is locked securely in position. WARNING: PREVENT ACCIDENTS - Adjustment of the seat mechanisms should only be carried out when the mower is at a standstill with the parking brake engaged.
1.33 OPERATING THE MOWER 1.33 Warning Systems Engine coolant overheating warning: The engine coolant warning light illuminates, the horn is actuated and the cutters stop.

Cutterhead Drive Switch Indicator Light Illuminates when the cutterhead drive switch is in the ‘off’...
1.36 OPERATING THE MOWER 1.36 Cutterhead Position Control The cutterheads may be raised or lowered independently using the bank of 3 lift control levers. To lower the cutterheads, operate the lift control levers in a downward direction until locked into position.
1.37 OPERATING THE MOWER 1.37 Weight Transfer / Traction Assistance A variable hydraulic weight transfer system is pro- vided for improving tyre grip with the grass surface - ‘Traction Assistance’. Hydraulic pressure in the cutterhead lift system provides a lifting force which reduces cutterhead weight on the ground and transfers the weight as a downward force onto the mower’s tyres.
1.38 OPERATING THE MOWER 1.38 Starting The Engine Cont’d Turn the ignition key to the ‘start’ position ‘III’ and hold to crank the engine. As soon as the engine starts release the ignition key back to position ‘I’. WARNING: PREVENT DAMAGE - When the engine is operating all warning lights should be ‘off’.
1.39 OPERATING THE MOWER 1.39 Unblocking Cutting Cylinders Cont’d NEVER ATTEMPT TO ROTATE THE CUTTING CYLINDERS BY HAND as 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.
1.40 OPERATING THE MOWER 1.40 General Operating Hints 1. 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.
Height of cut gauge: An optional height of cut gauge is available to assist in achieving accurate cut height settings. It is suitable for both fixed and TORO part no. 63-01-760 floating cutterheads.

Check rear wheel alignment: To prevent excessive tyre wear and ensure safe machine operation, the rear wheels must be correctly aligned to ‘toe - in’...
1.56 MAINTENANCE 1.56 Cutterhead Cylinder To Bottom Blade Adjustment IMPORTANT: PREVENT DAMAGE - It is essential that the relationship between the bottom blades and the cutting cylinders is kept in good adjustment in order to ensure good cutting performance, minimum power consumption and prolonged life for the cutting edges. Carry out the following procedure before commencing work and re-check the settings every few hours.
1.57 MAINTENANCE 1.57 Cutterhead Back Lapping This process is recommended for restoring the sharp cutting edges to cylinders and bottom blades which are essential for good quality grass cutting. This process can only deal with a small amount of metal removal to restore the cutting edges. If the blade edges are seriously worn or damaged it will be necessary to remove the component parts and have them reground.
1.58 MAINTENANCE 1.58 Cutterhead Grinding It will be necessary to carry out a grinding operation to correct cylinder spiral edges or bottom blade edges which have become excessively rounded or distorted. Bottom blades which are nearing the end of their wear life should be replaced.
1.59 MAINTENANCE 1.59 Towing The Mower Towing procedure: Connect a rigid tow bar between the towing eye on the mower and a suitable towing vehicle. Ensure that the towing vehicle specification is suited to braking the combined vehicle weight to rest whilst effecting complete control at all times.
