How to adjust a PTO driveline

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 figure on right). If determined that the drive line is too long, follow these procedures to adjust the length: separate the two drive line halves. Connect one half to the tractor PTO and the other half to the implement. Raise and lower the machine 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 guard tube leaving a 2" gap between the end of the guard tube and bell guard. Cut off both guard tubes the same amount as marked in step 2. Shorten both drive tubes the same amount as guard tubes. De-burr and clean filings from drive tubes and apply grease to outside of inner telescoping tube. Reassemble the drive line halves and connect to tractor and implement. Raise and lower implement again to be sure drive line does not bottom out in shortest position and has a minimum overlap of 6" in the longest position.
