Anleitung Zusammenfassung
DECK BELT REPLACEMENT (NOTE: Use only genuine Bush Hog replacement parts) 1. Remove the R.H. and L.H. deck shield assemblies (Fig. ). 2. Relieve the spring tension by loosening the two 5/16” hex nuts on the spring adjustment eye bolt. 3. Remove the old belt. 4. Install the new belt being sure the belt is properly routed and positioned in all sheave grooves. 5. Adjust tension on the belt by adjusting the length of the spring on the idler (See Deck Belt Adjustment section). 6. Replace the deck shield assemblies. Deck Lift Pedal Height Adjustment Pin Deck Lift Spring Adjustment Nut Deck Upper Chain Fastener WARNING TO AVOID SERIOUS BURN INJURIES: ALLOW ENGINE, OIL AND HYDRAULIC FLUIDS TO COOL BEFORE SERVICING TRANSMISSION OR ENGINE SYSTEM CAUTION TO AVOID CLEANING SOLVENT FIRES: AVOID USING FLAMMABLE SOLVENTS. AVOID AREAS WITH IGNITION SOURCES WHEN USING FLAMMABLE SOLVENTS. Deck Shield DECK BELT DIAGRAM Eye Bolt Adjustment Spring Loaded Idler Spring Length 44” Deck - 6-7/8”, 52” Deck - 7-1/2” Rear Trunnion Level on Mower Deck .12” Spacer At Front End HYDROSTATIC BELT DIAGRAM HYDROSTATIC TRANSAXLE BELT TENSION ADJUSTMENT 1. Stop engine and remove key. 2. The hydrostatic transaxle belt tension is adjusted through a spring loaded idler pulley. 3. The tension can be adjusted by loosening the (2) hex nuts on the end of the spring support bolt and turning them until the spring length is 37/ 16” (Shown at right). Tighten the jam nuts together. HYDROSTATIC TRANSAXLE (MOTION DRIVE) BELT REPLACEMENT 1. Stop engine and remove key. 2. Relieve the belt tension on the drive belt (See Belt Adjustment section) and drop the belt from the electric clutch deck pulley at the rear of the unit. Clutch Anti-rotation Bracket Spring Loaded Idler Spring Support Bolt Adjustment Spring Length 3-7/16” 3. Remove the electric clutch anti-rotation bracket at the rear of the unit. 4. Relieve the spring tension on the motion drive belt by loosening the (2) hex jam nuts on the end of the spring support bolt. 5. Remove the old belt. 6. Install the new belt being sure the belt is properly routed and positioned in all sheave grooves. 7. Adjust tension on the belt by adjusting the length of the spring on the idler (See Belt Adjustment section). 8. Reinstall the electric clutch anti-rotation bracket, the deck belt and re-tension the deck belt (See Deck Belt Adjustment section). WARNING HIGH PRESSURE HYDRAULIC FLUID LEAKS CAN PENETRATE SKIN CAUSING SERIOUS INJURY AND GANGRENE. INJECTED FLUID MUST BE SURGICALLY REMOVED WITHIN A FEW HOURS BY A DOCTOR FAMILIAR WITH THIS TYPE OF INJURY. TO AVOID SERIOUS INJURY FROM PRESSURE LEAKS: . USE CARDBOARD AND NOT HANDS TO SEARCH FOR LEAKS. . RELIEVE HYDRAULIC PRESSURE BEFORE WORKING ON SYSTEM. . CHECK HYDRAULIC HOSES, LINES, AND CONNECTIONS FOR TIGHTNESS AND GOOD CONDITION BEFORE APPLYING SYSTEM PRESSURE. START-UP MAINTENANCE Bush Hog recommends the use of SAE 20W50 motor oil in the hydrostatic reservoir. HYDROSTATIC TRANSAXLE MAINTENANCE The hydrostatic transaxle units normally do not require regular fluid changes. The system filter should be changed after the first 50 hours of break-in, then every 200 hours thereafter. The fluid and filter should be changed and the system cleaned if the fluid becomes contaminated with foreign matter (water, dirt, etc.). FLUID VOLUME AND LEVEL Certain situations may require additional fluid to be added or even replaced. Refer to the Figure below for the proper fill port location. 79 fl. oz. is the correct amount of fluid to add to an empty transaxle. The level of fluid in the transaxle may be checked by removing the plastic breather tube and inserting a clean, straight metal rod down through the fill port until it bottoms out. Remove the rod and the oil should extend approximately 4-1/4” up the rod. IMPORTANT Do Not Overfill If you overfill the transaxle while the unit is “cold”, it may overflow as it reaches normal operating temperatures. The oil level should not be above the manufacturer’s suggestions outlined in this manual. This will allow the space needed for the oil to expand as it warms up. Recheck the fluid level once the unit has been operated for approximately one minute. FLUID CHANGE In the event of oil contamination or degradation, oil addition or change may alleviate certain performance problems. It is essential that the unit exterior be free of debris prior to fluid maintenance. Remove the oil drain plug from the bottom of the unit to facilitate oil change. When reinstalling oil drain plug torque the plug to 180 - 240 in. lbs. 17 Void Air Space - 1-78” Correct Fluid Level - 4-1/4” Fill Port - Insert rod through this port to check fluid level. IMPORTANT When tightening the filter insure proper torque value of 20 - 50 in. lbs. is applied. Filter is plastic. Excessive torque will damage filter. Due to the effects air has on eficiency in the hydrostatic drive applications, it is critical that it be purged from the system. These purge procedures should be implemented...
