Drive out sheared bolt with hammer and punch. C. Align holes and install new shear bolt. Use only genuine Bush Hog replacement shear bolt. (Figure 4-3) D. Slide yoke shield securely in place. 4-5 SLIP CLUTCH OPERATIONAL CHECK After tiller has been stored for an extended period of time, perform the following operational check: A. Loosen eight nuts retaining clutch springs exactly one full turn. B. With tiller blades firmly on ground and tractor at idle speed, engage tractor PTO drive 2-3 seconds. Clutch should slip without turning blades. If clutch does not slip, contact your authorized Bush Hog dealer. C. Retighten nuts to within 1/64” of original position. Initial spring length is shown in Figure 4-4. CAUTION FAILURE TO RETIGHTEN SPRING NUTS TO ORIGINAL POSITION MAY CAUSE DAMAGE TO TILLER AND/OR TRACTOR DUE TO IMPROPER SLIP CLUTCH TORQUE SETTING. 4-6 SLIP CLUTCH ADJUSTMENT The slip clutch is factory preset to the correct torque for protecting implement and tractor. Periodic adjust- ment is recommended; refer to section 4-5. Should adjustment be needed, first check to be sure all spring lengths are within 1/64” of being the same. Initial spring lengths are shown in figure 4-4. If neces- sary, loosen nut on any spring that is unequal. Adjust all eight spring retaining nuts 2/3 of a turn (2 flats on a nut) and check clutch slippage. If further adjustment is necessary, do so in 1/3 turn increments or consult your Bush Hog dealer. Adjust only to provide suffi- cient torque to prevent slippage under normal condi- tions. When rocks, roots, etc. are present, occasional slippage is normal for drivetrain protection.

Do not lift heavy parts or assemblies. Use crane, jack, tackle, for trucks or other mechanical devices. 2. Select an area for assembly that is clean and free of any debris which might cause persons working on the assembly to trip. 3. Arrange parts to be assembled neatly in the work area and have tools or other mechanical assisting devices in easy reach. 4. Inspect all parts and assemblies thoroughly and remove any sharp edges, grease, oil or dirt which might cause pieces to slip when handling. 5. Preview the assembly instructions in your operator’s manual before proceeding further. 6. If the assembly instructions call for parts or assemblies to be blocked up, use only blocking material that is in good condition and is capable of handling the weight of the assembly to be blocked. Also insure that the blocking material is on a clean, dry surface. 7. Never put hands or any other part of body under blocked up assemblies if at all possible. 8. Always wear goggles or safety glasses when hammering, grinding or drilling metal parts. 9. If the assembly calls for welding or cutting, be sure that there are no flammable materials close at hand and that bystanders have taken necessary precautions. AFTER COMPLETING ANY ASSEMBLY STEP, THOROUGHLY READ THE NEXT STEP IN THE ASSEMBLY INSTRUCTIONS BEFORE PROCEEDING WITH THAT STEP. 10. After completing assembly, thoroughly inspect the machine to be sure that all nuts, bolts, hydraulic fittings or any other fastened assemblies have been thoroughly tightened. 13 14 A. Insert parking stand onto mounting bracket and retain with pin. Fasten parking stand bracket to tiller end plate using two 3/8 x 1” bolts, lockwashers and nuts. B. Attach PTO driveline to gearbox input shaft. Make certain driveline yoke is securely locked into position and driveline shields are in place and in good condition. C. Fasten left and right mast struts to angle bracket using six 1/2 x 1-1/4” bolts, lockwashers and nuts. (Figure 5-1) D. Loosely install one 3/8 x 3” bolt, spacer bushing, lockwasher and nut between tops of mast struts. E. Place re...
