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 will be necessary to shorten the PTO
driveline to match your specific tractor. Use the
following procedure to shorten the driveline.
1. Raise the 3-point hitch so the attachment gearbox
input shaft is in line with the tractor PTO shaft.
This position is produces the shortest distance
between the gearbox and tractor PTO shafts.
Shut down the tractor, leaving the attachment in
this position. 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 end approximately 3” short of the universal
joint shield on the opposite section. If the shaft is
too long, measure 3” back from the universal joint
and mark it on the opposite end. Do this to both
ends of the driveline.
IMPORTANT:
Do not cut the driveline until steps
4 and 5 have been completed.
4. Remove the blocks from under the attachment.
Raise and lower the attachment to determine the
position with the greatest distance between the
gearbox and tractor PTO shafts. Shut the tractor
off, leaving the attachment in this position.
Securely block the attachment in this position.
INSTRUCTIONS FOR SHORTENING THE DRIVELINE
5. Hold the driveline sections parallel to each other
and check for a minimum 6” of overlap. Overlap
will be the distance between the marks made in
step 3.
6. If the driveline needs to be cut, remove the
marked section of the driveline and shield using a
hack saw.
7. Apply multi-purpose grease to the inside and
outside of both driveline ends and slide them
together.
8. Raise and lower the attachment to check that the
driveline assembly does not jam at any point. If it
does, cut equal amount off of each end, making
sure there is always at least 6” of overlap.
9. Check the full range of intended motion of the
attachment and make sure the swinging drawbar
on the tractor does not contact the driveline at any
point. If necessary, the drawbar can be moved
forward or removed on most tractors (refer to your
tractor’s operator’s manual).
