In the collapsed position the driveline should be approximately 2" from bottoming out to
prevent possible damage to the tractor or implement. When the PTO is in the maximum
extended position, the ideal minimum overlap of the two halves should be approximately
6" (see fig. 15).
If determined that the driveline is too long. Follow these procedures to adjust the length:
1. Separate the two driveline halves. Connect one half to the tractor PTO and the
other half to the mower.
2. Raise and lower the mower with the 3 point hitch to find the position where the
driveline is shortest. Hold the half shafts side by side and mark the desired length
on the outer female tube guard leaving a 1

2
" gap between the end of the guard
tube and bell guard.
3. Cut off both guard tubes the same amount as marked in step 2.
4. Shorten both drive tubes the same amount as guard tubes.
5. De-burr and clean filings from drive tubes and apply grease to outside of inner
telescoping tube.
Reassemble the driveline halves and connect to tractor and mower. Raise and lower
mower again to be sure driveline does not bottom out in its shortest position and has a
minimum overlap of 6" in the longest position.
CAUTION: Always work with the driveline as straight as possible. This will
prolong its life and that of its components. It is advised not to work at an angle
greater than 15 degrees.
4.07 - Transport
Before raising the mower for transport, the tractor top link must be adjusted so when
lifted, the rear of the machine is higher than the front (the mower's nose is tilted
downward). To do this, shorten the tractor top link until the top hitch plate is locked
forward and no longer able to pivot. This will keep the mower locked in position and
minimize the shaking and bouncing during transport which can damage the hitch or
frame.
When raising the mower be sure the PTO driveline does not hit either the mower or the
tractor. During transport the mower should not be lifted over 14"-16" from the ground.
CAUTION: Make sure PTO is disengaged and blades have stopped turning before
raising mower to full transport position.
Do not tow tractor and mower behind other vehicles. Use a properly equipped
trailer with heavy tie-downs for towing operations.
