PTO Driveline Length Check
Due to variations in distances between tractor PTO
shafts and implement input shafts, drivelines may
need to be shortened or a longer shaft may be
required.
When fitting the implement to the tractor, the
PTO driveline, with telescoping sections, must
be inspected. When the sections are at the most
compressed operating position, the sections must
not “bottom out”.
At its shortest length, there must be at least 2 in.
(50.8 mm) of clearance between each section end
and opposite section end at the most compressed
operating position.
When the sections are at the most extended
position, there must be sufficient engagement
between the sections.
At its farthest operating extension, a minimum
section engagement of 33% of shaft length must
be maintained.
WARNING
AVOID INJURY OR DEATH
• Do NOT exceed the rated implement PTO speed.
• Stay clear of rotating driveline.
• Keep bystanders away.
• Keep hands, feet, clothing and long hair away.
• Keep PTO shields and all guards in place.
• Disengage PTO, move the tractor controls to
the Neutral position, stop the engine and make
sure all rotating components are stopped before
leaving the operator’s position.
• Do NOT service the tractor or implement with
the PTO engaged.
• Do NOT service the implement in a raised
position unless properly blocked and with all
rotating components stopped.
• Disengage PTO for road travel.
PTO Driveline Bottoming Out Check
Stop the engine and leave the operator’s position
(See “Leaving The Operator’s Position” in
Operation section).
Make sure the PTO driveline and all rotating
components have come to a complete stop before
leaving the operator’s position (if applicable).
Figure 18
1. Disconnect the PTO driveline from the tractor and
slide the PTO driveline together until fully retracted
(compressed).
2. Measure the retracted (compressed) length of PTO
driveline [Figure 18] .
3. Extend the PTO driveline 2 in. (50.8 mm) from the
retracted length and place a mark on the inner guard
at the end of the outer guard
[Figure 18].
4. Reattach the PTO driveline to the tractor PTO shaft.
5. Enter the operator’s position. Start the engine.
6. With the rear PTO DISENGAGED, raise and lower
the implement and watch the PTO driveline extend
and retract.
7. If the outer PTO driveline guard slides in (retracts)
over the mark at any point of travel, the PTO driveline
needs to be shortened.
