Driveline Length Check - Alamo A60 Operator's Manual

9.1 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 operating extension, a
minimum profile engagement of 9" must be maintained.
"Bottoming Out" Check Procedure
• Disconnect driveline from the tractor and slide
the profiles together until fully compressed.
• Place a mark on the inner shield 1/8" from the
end of the outer shield.
• Reattach the driveline to the PTO Shaft.
• 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. OPS-R-0004_A
