9. PTO Shaft Connection
A PTO drive line is supplied with the machine to
complement the wide variety of 3-point hitches
available on tractors today. The drive line length may
need to be adjusted. It is very important that the drive
line be free to telescope and not to bottom out when
going through its working range.
IMPORTANT! If the drive line bottoms out, the
bearings on both the machine and tractor PTO
shaft will be overloaded and could fail.
9.1 Determine Correct PTO Shaft
Length
Clear the area of bystanders, especially small children.
1. Attach the chipper to the tractor (see section 4.6)
but do not attach the drive line.
2.
Raise the machine until the input shaft is level with
the tractor PTO shaft.
3. Measure the dimension (A) between the locking
grooves on the tractor PTO shaft and the machine
input shaft.
4. Measure the same dimensions on the compressed
drive line.
5.
If the compressed drive line dimension (B) exceeds
the machine dimension (A), the drive line will have
to be cut.

uncut driveline dimension (B)
When cutting the drive line, follow this
procedure:
6. Subtract the machine dimension (A) from the uncut
drive line dimension (B) or (B–A = C).
7. Add one inch (25 mm) to dimension (C) to
determine the Cut Off dimension.
8. Use a hacksaw to cut dimension (C) from both
ends. Cut both the plastic tubes and the metal
cores.
