8. Attach the driveline to the gear box input shaft using the 5/16” grade 5 hex cap screw, the
5/16” lock washer, and the 5/16” NC hex nut. Tighten the hex nut. Insert the 1/4” x 3/8” set
screw from the hardware kit in the hole on the yoke that aligns with the 3/16” groove on the
gear box input shaft. Tighten.
Attention
The 3/8” hex cap screw provides shear protection. Use a grade 2 3” bolt (not provided) only to avoid
damage to the gear box or auger.
Important
The universal joint should be greased with a good grade chassis lube every week. At the beginning of
each season, grease the sliding drive shaft members with a moly grease. All diggers are equipped
with quick-detach universal joints on the PTO end for a 1-3/8” splined shaft.
9. Attach the tractor end of the driveline to the tractor PTO shaft. Push in the spring-loaded pin
in the splined yoke and slip it on the splined PTO shaft of the tractor. Release the pin and
push in until it locks securely in place. Note: It will be necessary to obtain a 1-1/8” to 1-3/8”
sleeve spline adapter if your tractor PTO shaft has a 1-1/8” spline.
10. Attach and secure both chains on the driveline to the boom.
Note: When the 7/8” diameter pull pins in the A frame are too small for the holes in the lift arms,
bushings should be used to obtain a proper fit.
Important:
The gearbox is shipped without lubricant. Refer to the next section before using the digger.
Always perform maintenance operations with the tractor engine off, the PTO drive disengaged, and
the auger point resting on the ground.
