Before starting to assemble the tiller, be certain to remove all of the parts from the. carton. Assembly For ease in assembling the tiller, follow the sequence of steps outlined below : 1. Remove all masking tape from the ends of the tine shaft and the drive pulley shaft of the chain guard assembly. 2. To attach the deflector assembly to the chain guard assembly; remove 2 mounting bolts from each side of the chain guard as shown in figures 1 & 2. Mount the deflector so that the holes in the mounting brackets line up with the holes in the chain guard assembly as shown in figure 3, and replace the mounting bolts in their original holes. Tighten the bol;e securely. 3. Assemble the left hand inner tine assembly to the left hand outer tine assembly and fasten with a pin and cotter pin. Assemble the right hand inner tine assemble to the right hand outer tine assembly, and fasten with a pin and cotter pin. NOTE: the inner tine assemblies can be identified by the constant diameter of the hub fastened to the tine plate. The long end of this hub is. inserted into the long end of the hub of the outer tine assemblies and is fastened as described above. CAUTION: As it is possible to mount the tine assemblies incorrectly to the tine shaft, pay particular attention to the following: Assemble the tines to the tine shaft as shown in figure 4 so that the sharp edges of the top tines face toward the front of the tractor. Fasten the tines to the tine shaft with a pin and cotter pin on each end of the tine shaft. When the tines are mounted, check once more to be certain that the sharp edges of all tines face in the correct direction. ry 4. Assemble the tiller drive pulley to the tiller-drive shaft as shown in figure 3. The pulley is held in place by a key and set screw and is to be mounted with the hub of the pulley facing away from the chain guard. r> 2 Attachment For ease in attaching the tiller to the tractor, follow the sequence of steps as outlined below. 1. Assemble the tiller mounting bracket to the upper portion of the rear frame of tractor as shown in figure 5, using hex capscrews, lockwashers and hex nuts provided. 2. Position the tiller in back of the tractor and insert the tiller lift bar into the tube of mounting bracket as shown in figure 5. Depress the tractor handles until the mounting bracket is lowered sufficiently to allow the tiller lift bar to slide into the tube. Secure in place with a pin and hair pin cotter. Release the tractor handles and the tiller will raise and swing forward.

Loosen the setscrew on engine pulley. Remove pulley and reinstall in a reversed position, with the larger diameter on outer end of engine shaft. Be certain to replace pulley key in shaft and retighten set screw. 4. Separate the transmission drive pulley from its pulleyhubby removing the 3 hex capscrews and lockwashers. Replace this pulley with the tiller drive pulley group as shown on page 8. The 10" pulley is mounted against the pulley hub; and . the spacer ring is mounted between the 10 " pulley and the 5 1/2" pulley, using hex capscrews 2" long. Install belt guard as shown. 5. Install drive belt from engine pulley to transmission drive pulley, and then install the tiller drive belt as shown in figure 6. Check the pulleys for alignment with each other, and adjust if required. When pulleys are in line, tighten the set screws securely. The 2 .V-belts that transmit power from the engine to the tiller drive shaft are designed and manufactured to provide long and satisfactory service. Because of the special design of these belts, itis urged that you replace them only with genuine replacement belts ordered from your dealer. Consult the parts list for correct part numbers for these belts when replacement is necessary. Adjustment of tension of the tiller drive belt is regulated by the belt tension adjusting screw shown in figure 5 . Turn the handle in a clockwise direction to increase the belt tension and counter-clockwise to decrease tension. The belt should have tension sufficient to transmit power to the tiller drive shaft. AVOID EXCESSIVE TENSION, as it will cause premature belt failure. Lubrication The tiller is lubricated through 3 grease fittings . Two fittings are located on the tiller drive shaft housing and the other is located on the right hand side of the chain guard. See figures 1 & 2. Lubricate these fittings every 3 hours of operation with a good grade of general purpose automotive type grease loaded in a standard grease gun. Be certain to wipe any dirt from the fittings before applying the grease gun. Failure to clean the grease fittings will result in grit being for...
