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 12” must be maintained.
7.1 Driveline Length Check
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!
7. DRIVELINE ATTACHMENT
The driveline yoke and tractor PTO shaft must be dirt
free and greased for attachment.
To connect the mower driveline to the tractor PTO output
shaft, twist driveline yoke collar and align the grooves
and splines of the yoke with those of the PTO shaft.
Push the driveline yoke onto the PTO shaft, release
the locking collar, and position the yoke until the locking
collar balls are seated onto the PTO shaft. Push and
pull the driveline back and forth several times to ensure
a secure attachment.
WARNING!
When attaching the PTO yoke to the Tractor PTO shaft, it is important that the spring
activated locking collar slides freely and the locking balls are seated securely in the groove
of the PTO shaft. A driveline not attached correctly to the Tractor PTO shaft could slip off
and result in personal injury and damage to the cutter.
