IMPORTANT: Always check driveline length during initial setup and when connecting to
a different tractor.
In the collapsed position the driveline should be approximately 2” from bottoming out to
prevent possible damage to the tractor or implement. When the driveline is in the
maximum extended position, the ideal minimum overlap of the two halves should be
approximately 6”
(see fig. 11) .
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 shredder.
2. Raise and lower the shredder 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
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.
6. Reassemble the driveline halves and connect to tractor and shredder. Raise and
lower shredder 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 Authorized
Company Dealer.
