Attaching the PTO Shaft to the Tractor and Chipper
1. Insert the Key into the 3-Point Hitch Drive Shaft of the Chipper
(Figure 21).
2. Align the Key Slot of the PTO Shaft with the Key in the Shaft and slide it onto
the Shaft.
NOTE : Do not allow the 3-Point Hitch Shaft to extend more than 1/4" into the U-
Joint. This will allow proper clearance to prevent hitting the Grease Fitting.
3. Secure the PTO Shaft with the two Set Screws from the Hardware Package.
NOTE: If you plan to leave the Chipper attached to the Tractor for extended periods,
apply thread lock to the Set Screws to help secure them in place.
4. Pull the Locking Ring while sliding the PTO shaft onto the Tractor PTO
Spline
(Figure 22).
5. Release the Locking Ring and continue sliding the PTO Shaft on until the
Locking Ring releases and locks into the detent in the Tractor PTO Spline.
6. Secure the PTO Shaft Safety Chains to stationary parts of the Chipper Frame
and Tractor to stop the Guard from turning
(Figure 23).
You must install the 1/4" X 1/4" X 1-1/4" key supplied in the hardware
package where the PTO shaft attaches to the chipper. Failure to do so will
result in damage to the machine and is not covered under warranty.
