OPERATION
7.1 Driveline Length Check
Raise mower and watch the Driveline as it
approaches the colored tape. If the distance
between colored tape and the end of the outer
shield tube is 2" or less, Drive Tubes should be
shortened per figure Op-10.
Always maintain 2" clearance when operated in
shortest working position. Shorten inner and outer
guard tubes equally. Shorten inner and outer sliding
profiles by the same amount that the shield tubes
were shortened. Round off all sharp edges and
remove burrs. Grease sliding profiles. Figure Op-
11_A.
Lower mower to lowest position possible. Turn off
the Tractor and apply Parking Brake. Apply a
second piece of colored tape to the Inner Shield 1/
8” from the end of the Outer Shield. Disconnect
Driveline from Tractor and then separate the two
Driveline halves. Check the distance from the new
piece of colored tape to the end of the inner profile.
If distance is less than 8" consult dealer to obtain a
longer Driveline. Driveline Tube engagement must
always exceed 8".
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. Push and pull the driveline back and forth
several times to ensure it is securely attached. A driveline not attached correctly to the
Tractor PTO shaft could come loose and result in personal injury and damage to the
Implement.

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
driveline can cause personal injury.
