Driveline Length Check - Schulte FX-520 Operator's Manual

7. DRIVELINE ATTACHMENT
Pivot the divider gearbox shield back, and out of
the way. Remove any tape from the gearbox shafts,
and any booklets from the driveline. Slide the
clamp end of the tractor driveline onto the divider
input shaft. Insert the clamp bolts supplied with the
tractor driveline and push the yoke until the
grooves line up and the bolts fall into place. Ensure
bolts are tightened with lock washers and nuts.
Connect the CV assembly to the tractor PTO. Pull
the driveline collar back and align the grooves
between the cutter driveline and Tractor PTO. Push
the driveline onto the Tractor PTO, release locking
collar and position the yoke until the locking collar
balls are seated onto the Tractor PTO shaft groove.
Swing the PTO support down, and out of the way so it does not interfere with the driveline during operation.
Failing to do so could cause severe damage to your driveline.
Pull and push the quick disconnect yoke several times to ensure that the yoke is connected
to the PTO shaft.
When attaching the PTO yoke to the Tractor PTO shaft, it is important that the clamping
cone is securely seated into the groove of the PTO shaft and properly tightened. A driveline
not attached correctly to the Tractor PTO shaft could slip off and result in personal injury
and damage to the cutter.

7.1 Driveline Length Check

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.
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 extension, a minimum
profile engagement of 6" must be maintained for a Constant Velocity (CV) tube type driveline and a minimum
engagement of 6" for non-CV solid shaft drivelines.
