The tractor must be equipped with
working PTO shield. Never adjust or move the
driveline when connected to the tractor and the
tractor’s PTO drive is engaged to avoid serious
injury or death.
In some cases, it may be necessary to shorten the
PTO assembly to match your particular tractor. This
is done as follows:
1. Fully raise the stump grinder cutting wheel and
swing the stump grinder to be centered. This
position gives the shortest distance between the
tractor and gearbox shafts. Shut down the
tractor, leaving the attachment in position of
shortest distance between the shafts. Securely
block the attachment in this position.
2. Pull the driveline apart. Attach the outer (female)
section to the tractor PTO shaft. Make sure the
driveline is locked into place.
3. Hold the driveline sections parallel to each other
to determine if they are too long. Each section
should stop approximately 3” short of reaching
the universal joint shield on the opposite section.
If the shaft is too long, measure back 3” from the
universal joint and mark it on the opposite end.
Do this on both ends of the driveline.
IMPORTANT: Do not cut until steps 4 and 5 are
completed.
4. Raise and lower the stump grinder cutting wheel
and swing side to side to determine the position
with the greatest distance between the PTO shaft
and the gearbox input shaft. Shut the tractor off,
leaving the stump grinder in the position of
greatest distance between the shafts. Securely
block the attachment in this position.
5. Hold the driveline sections parallel to each other
and check for a min
imum overlap of 6”. Overlap
will be the distance between the marks.
INSTRUCTIONS FOR SHORTENING THE DRIVELINE
6. If the driveline needs to be cut, remove the
marked section of the driveline and shield with a
hack saw.
7. Apply multi-purpose grease to the inside and
outside of both driveline ends and slide them
together.
8. Install the driveline on the tractor and stump
grinder.
9. Raise, lower, and swing the stump grinder cutting
wheel to check that the PTO assembly does not
jam. If it does, cut equal amount off from each
end.
10. Check and make sure the swinging draw bar on
the tractor does not contact the driveline. The
draw bar can either be moved forward or
removed on most tractors (refer to your tractor’s
owner’s manual).
