5. 5 DRIVELINE DIMENSION
A PTO driveline is supplied with the machine. To accompany the variety of 3 point hitch geometry
available today, the driveline can be too long for most machines or too short for others. It is very im-
portant that the drive- line be free to telescope but not to bottom out when going through its work-
ing range. If the driveline bottoms out, the bearings on both the machine and tractor PTO shaft will
be overloaded and fail in a short time.
1. To determine the proper length of the driveline, follow this procedure:
a. Clear the area of bystanders, especially small children.
b. Attach the chipper to the tractor (see section 5.8) but do not attach the driveline.
c. Raise the machine until the input shaft is level with the tractor PTO shaft.
d. Measure the dimension between the locking grooves on the tractor PTO shaft and the
machine input shaft.
e. Measure the same dimensions on the compressed driveline.
f. If the compressed driveline dimension exceeds the machine dimension, the driveline will
have to be cut.
