SAFETY PRECAUTIONS 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. - Page 8 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 modification to any part of the machine or brake coupling mechanism.
- Page 9 SAFETY PRECAUTIONS Preparation continued Check the mower hydraulic system, particularly the hydraulic hoses, fittings 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.

Page 57: General Operating Hints 1.57
1.57 OPERATING THE MOWER 1.57 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 tractor engine speed be kept as high as possible without exceeding 540 rpm P.T.O. - Page 58 1.58 OPERATING THE MOWER 1.58 General Operating Hints continued WARNING: PREVENT ACCIDENTS - Take care when travelling over obstacles such as roadside kerbs. ALWAYS travel at slow speed over obstacles to prevent damage to the tyres and wheels. Ensure that tyres are inflated to the recommended pressures.
- Page 59 Correct servicing will prolong the working life of the machine and safeguard the “Toro warranty”. Always fit genuine ‘Toro service parts’ as these are accu- rately matched to the required duty. Dirt and contamination are the enemies of any hydraulic system.
- Page 60 1.60 MAINTENANCE 1.60 Maintenance continued WARNING: PREVENT ACCIDENTS - Use hazardous substances carefully. The following fluids are identified as being hazardous; Substances Assessed risk Diesel oil Lubricating oil Hydraulic oil Grease When using any of the above fluids it is recom- mended that eye protection and gloves are worn and that care is taken to prevent spillage.
- Page 61 Change the hydraulic oil return filter. Remove the top of the return filter assembly. Withdraw the filter element canister and discard. Refit a new filter canister (Toro part No: 65-06-483) and replace the screw top taking care to ensure that the ‘O’ ring seal is correctly located.

Page 68: Cutterhead Cylinder To Bottom Blade Adjustment 1.68
1.68 MAINTENANCE 1.68 Cutterhead Cylinder to Bottom Blade Adjustment IMPORTANT: PREVENT DAMAGE - It is essential that the relationship between the bot- tom 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. - Page 69 1.69 MAINTENANCE 1.69 Cutterhead Cylinder to Bottom Blade Adjustment continued Do not be tempted to over adjust, thus causing heavy contact between the cylinder and bottom blade, as this will cause very rapid uneven wear to take place leading to tram lining and waviness of the cutting edges.
-
Page 70: Cutterhead Back Lapping 1.70
1.70 MAINTENANCE 1.70 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. -
Page 71: Grinding
1.71 MAINTENANCE 1.71 Cutterhead Back Lapping continued 9. If further backlapping is necessary repeat steps 3 to 8. 10. Thoroughly remove and wash off all traces of the carborundum paste from the cylinders and bottom blades. 11. Move the control lever to the ‘Normal Operation’. - Page 72 1.72 MAINTENANCE 1.72 Cutterhead Bottom Blade Replacement continued The new bottom blade must be ground on its holder prior to refitting to the cutterhead. Adjust the cut- ting cylinder position to give adequate clearance for fitting the new bottom blade holder. Refit the bottom blade holder assembly to the cutterhead us- ing the original fixing bolts and tighten to a torque of 35Nm (26 lbf.ft).
