4�7 PTO DRIVELINE (IF
EQUIPPED)
A PTO drive line is supplied with the machine. To
accompany the variety of 3 point hitch geometry
available today, the drive line can be too long for some
machines or too short for others. It is very important
that the drive line be free to telescope but not to bottom
out when going through its working range. If the drive
line 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 drive line,
follow this procedure:
a. Clear the area of bystanders, especially small
children.
b. Attach the spreader to the tractor (see section
4.6) but do not attach the drive line.
c. Raise the machine until the input shaft is level
with the tractor PTO shaft.
d. Measure the dimension (A) between the locking
grooves on the tractor PTO shaft and the
machine input shaft.
e. Measure the same dimensions on the
compressed drive line.
f. If the compressed drive line dimension (B)
exceeds the machine dimension (A), the drive
line will have to be cut.
2� When cutting the drive line, follow this
procedure:
a. Subtract the machine dimension (A) from the
uncut drive line dimension (B) or (B-A=C).
b. Add 1 in. (25 mm) to dimension (C) to determine
the cut off dimension.
c. Use a hacksaw to cut dimension (C) from both
ends. Cut both the plastic tubes and the metal
cores.
d.
Use a file to remove the burrs from the edges
that were cut.
e. Assemble the two ends of the shaft.
f. Make sure the shaft can telescope freely. If it
does not, separate the two parts and inspect
for burrs or cuttings on the shaft ends. Be sure
it telescopes freely before installing.
g. Drive around, a correctly sized shaft should not
bottom out or come apart.
NOTE
Telescoping shaft
Should overlap at
least 6 in. (152 mm)
under load.
