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 1½” 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.
6. 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.
7. Install both driveline safety chains. One should be hooked in a hole on the outer
driveline yoke shield and to the tractor to restrict outer shield rotation. The second
one should be hooked in a hole on the inner driveline yoke shield and to the
implement to restrict inner shield rotation.
If determined that the driveline is too short for your tractor, contact your local dealer.
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.
