8.1 Driveline Length Modification

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.

8. 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, pull the driveline yoke collar back 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. OPS-R-0003_A

When attaching the Implement input driveline to the Tractor PTO, it is important that the

connecting yoke spring activated locking collar slides freely and the locking balls are seated

securely in the groove on the Tractor PTO shaft. A driveline not attached correctly to the Tractor PTO shaft

could come loose and result in personal injury and damage to the Implement.

(S3PT-17)

Before operating the Implement, check to make sure the Implement input 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. A broken drive line can cause personal injury.
