Note:
The PTO Driveshaft provided with your new machine is sized to fit a standard
category 1 PTO (1-3/8" DIA. x 6" Spline).
The PTO shaft on the tractor that is to use this machine must rotate
clockwise when viewing the PTO from the rear of the tractor. If the PTO rotates
counterclockwise, you must have your tractor modified by installing a gearbox to
reverse the direction of rotation.
The length of the PTO Driveshaft that is included with your new machine may need
to be modified. See the procedure for checking the PTO Shaft length needed and
modification instructions in this chapter.
1.
Back the Tractor to the Chipper and position the Lower Draft Arms near the
Chipper Hookup Pins (
Figure 11
).
2.
Slide the Lower Draft Arms onto the Chipper Hookup Pins and secure with
Tractor Hitch Pins (
Figure 12
).
3.
Position the Upper Draft Arm inside the Mounting Bracket and align with
the Mounting Bracket Holes (
Figure 13
).
4.
Insert the Tractor Hitch Pin to secure the Upper Draft Arm to the Chipper.
Calculating length of PTO Shaft needed
The PTO Shaft provided with your Chipper is 27" overall compressed length and
will work for most applications without modifications. Before you install the
PTO Shaft it is good practice to run through the following dimension checks to
calculate optimum PTO Shaft length to determine if modifications are needed.
Without the PTO Shaft installed, use the table below to record the dimensions
as outlined in the following steps.

1.
Lower the Chipper all the way onto the ground in the operating position.
Measure from the end of the Tractor PTO Shaft to the end of the Chipper
PTO Shaft and record this dimension in the “ON GROUND” row of the
table above (
