When fitting the mower to the tractor, the telescoping driveline must be inspected to ensure that at its most
compressed position, the profiles do not “bottom out”, and when at its farthest extended position, there is
sufficient engagement between the profiles to operate safely. At its shortest length, there must be at least
a 1” clearance between each profile end and opposite profile universal joint. At its farthest operating
extension, a minimum profile engagement of 10” must be maintained.
Shorten the driveline profiles as follows:
1. Remove the driveline from the tractor.
2. Raise and lower the mower to find the position
with the shortest distance between the tractor PTO
shaft and cutter gearbox. Shut down the tractor
and securely block the mower in this position.
3. Pull driveline apart and reattach yoke to PTO shaft.
4. Hold driveline sections parallel to one another and
measure back 1” from yoke of each shaft and place
mark on opposite section. Cut this length off with
a saw.
5. Round off all sharp edges and debur.
6. Thoroughly grease then reinstall the driveline.
7. Recheck for proper operation.
“
Bottoming Out” Check Procedure
1. Disconnect driveline from the tractor and slide the
profiles together until fully compressed.
2. Place a mark on the inner shield 1/8” from the
end of the outer shield.
3. Reattach the driveline to the PTO shaft.
4. Raise the mower and watch the driveline as it
approaches the mark. If the distance between the
mark and the end of the outer shield tube becomes
less than 2” at any point, the driveline must be
shortened.
7.2 Driveline Length Modification
Before operating the Mower, check to make sure the driveline will not bottom out or become
disengaged. Bottoming out occurs when the inner shaft penetrates the outer housing
until the assembly becomes solid-it can shorten no more. Bottoming out can cause serious
damage to the Tractor PTO by pushing the PTO into the Tractor and through the support
bearings or downward onto the PTO shaft, breaking it off.
WARNING!
Driveline in maximum compresses position.
