2 SERVICE. NOTES ~) GENERAL MAINTENANCE 054 & 953 MODELS IMPORTANT: Adiustment of Clutch Brake Pedal.. Adjust Pedal to ~" to position by adjusting Clutch Rod.. Depress Pedal to approximately the 3 dimension and swing Parking Brake lever until it holds Pedal at the 3" position. 3. Tighten Brake Rod Nut until Brakes lock. 4. This procedure must be followed after 0-5 hours of operation on initial run-in of Tractor. This adjustment should be repeated if the Clutch Pedal approaches the top of the slot.in the Belt Shield. Failure to adjust may result in failure of the main Drive Belt. ADJUSTMENT OF BELT GUIDES: Belt guide part 495 attaches to the frame and to the side of the engine and runs along the bottom side of drive belt. This guide should be adjusted so that there is ~t to K/' clearance between the belt and the guard. Rear Belt Stop part 4486 fits inside the right rear fender and extends down to the top of the drive belt on transmission - pulley. This belt stop should be adjusted so that it is ~t to K6 away from the top of the belt. Front Belt Stop part 4796 fits on the engine and extends down to the belt on the engine pulley. It should be adjusted so that it is ~t away from the top of the belt. BRAKE ADJUSTMENT: The brake band, located on the left side of the transmission, brakes the transmission and in turn stops the wheels. Adjust the nut on the brake rod so that, when you depress the clutch pedal all the way down, the band tightens aro und the brake drum just as the idl.er pulley releases the belt. Keep brake band and drum free from oil and dirt. jclutch Range / / /" to " Parking Brake Lever PARKING BRAKE ADJUSTMENT: After brake band and clutch-brake pedal have been adjusted, depress pedal until tractor brakes are locked. Pull parking brake lever back and adjust nut on bottom of lever shaft until level' will engage and hold pedal down. HYDRAULIC BELT ADJUSTMENT: Proper belt tension is maintained by removing the right hand belt guard and loosening the four (4) bolts holding the pump body to the frame. Pump may now be moved forward and backward to adjust belt. CARE OF THE TRACTOR Keep tractor greased and oiled regularly. See previous instructions for location of grease fittings, Check transmission and engine case oil levels. Keep engine air filter clean. Dirty filters use excessive fuel and reduces engine power and life. Keep tires properly inflated. Keep tractor covered and in a dry place when not in use. Check battery liquid after ev.ery 40 hours of use. If tractor has been in storage it may be necessary to recharge. Your tractor is only as good as the service you give it. See your Wheel Horse dealer for a thorough check-up after each season of use. Brake Range Ad lusting Nut Brake Rod Nut When replacing belts it is advisable to purchase them from your Wheel Horse dealer, as these belts are specifically designed for each tractor or attachment. A new drive belt may have a tendency to squeak during clutching, thls will stop after an hour or two of operation as the belt seats in the pulley

3 HYDRAULIC UNIT DESCRIPTION The Hydraulic Unit system built into your tractor is designed to give you hydraulic power for your attachments with fingertip control. This unit is a completely self-contained hydraulic gear pump, directional control valve and oil reservoiri with a companion hydraulic cylinder and hoses connecting the power unit with the cylinder. The unit has a built-in safety valve to eliminate ove.rloading of the hydraulic system and tractor attachments. IMPORTANT - Never run unit without fluid or warranty will be voided. If unit is taken apart for service make sure all parts are clean before assembling unit. After service it is advisable to install new fluid. When raising or lowering attachments, after urtitis either up or down, make sure handle is in neutral. Never hold open as this will cause harm to unit over a period of' time. SERVICING PUMP You must ADD OIL before starting engine to avoid damage to pump. Remove filler plug and fill to top of hole with fluid. NOTE: Filler plug is mounted off the vertical center line of the unit. This is to prevent over filling. An air space must be left in the top of tank, so no attempt should be made to completely fill reservoir. USE ONLY WHEEL HORSE OIL (Number 48). Replace plug and tighten. OPERATION To raise tractor attachments, pull handle toward you, upon release of handle it will return to the center or neutral position. A slightly sluggish action of the control lever returning to neutral may exist during the break-in period. A few hours of running time will eliminate this. After running unit a short time, check all fittings for fluid leaks.

9 "") /') ).0 November 4., 96 TO OUR DEALERS AND DISTRIBUTORS. ' SUBJECT; INTERCHANGEABILITY OF RMR-36,AND RMR-366 MOWERS We have had Ihquiries regardin~ the installation of 96 mowers on 963 tractors e THEY ARE CO}PLE'l'ELY H!,TERCIIANGEABLE, however, when the RMR-36 mower is installed on Models 633, 653, 753, it is necessary to reverse the fr'ont wheels to prevent any posslbity of the front wheels interfering with the mower skids. The front wheel hubs are offset and by' placing the long hub on the outside, the front tread width is reduced to give adequate clearance between the wheel and the skid. J~tuo/~ D. J. PALBYKIN I CUSTOMER RELATIONS MANAGER DJP:csu
