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 (Figure 14).
2. Raise the Chipper up until the Tractor PTO Shaft and
Chipper PTO Shaft are parallel with each other.
Measure from the end of the Tractor PTO Shaft to the
end of the Chipper PTO Shaft and record this
dimension in the “SHAFTS LEVEL” row of the table
above (Figure 15).
3. Raise the Chipper up as far as it will go. Measure from
the end of the Tractor PTO Shaft to the end of the
Chipper PTO Shaft and record this dimension in the
“FULLY RAISED” row of the table above (Figure 16)
NOTE: If your longest measurement exceeds 32" you will require a
longer PTO Shaft. Do not proceed with installation until you have a
longer PTO Shaft. If you have any questions, please visit us at
