3.4.1 Connecting the chipper and tractor
The PTO Drive shaft 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 Drive shaft 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.
2. Slide the Lower Draft Arms onto the Chipper Hookup Pins and secure with safety Pins.
3. Position the Upper Draft Arm inside the Mounting Bracket and align with the Mounting
Bracket Holes
4. Insert the safety Pin to secure the Upper Draft Arm to the Chipper.
