WARNING!
When attaching the PTO yoke to the Tractor PTO shaft, it is important that the spring
activated locking collar slides freely and the locking balls are seated securely in the groove
of the PTO shaft. A driveline not attached correctly to the Tractor PTO shaft could slip off
and result in personal injury and damage to the cutter.
IMPORTANT: Do not operate the PTO with the flex arm in the transport position for extended periods of time. This
may cause driveline vibration and will accelerate universal joint wear.
IMPORTANT: DO NOT use a non-CV tractor shaft. Driveline damage will occur when turning the implement.
For mowers equipped with a Constant Velocity (CV) driveline, the maximum turning angle between the tractor and
mower must be determined to ensure the joint angle does not over-extend which can cause CV joint damage.
Constant Velocity joints enable the driveline to operate smoothly with no vibrations and clattering at angles up to
70°. Angles greater than 80° can result in mechanical damage to the CV joint and mower driveline.
The Constant Velocity joint must be lubricated every 8 hours of operation as specified in the Maintenance Section.
Failure to properly lubricate the joint will result in accelerated wear and joint component failure.
CV Driveline Maximum Angle Check Procedure
1. With the mower attached to the tractor and the driveline disconnected from the tractor PTO stub make a
hard left turn until there is approximately a 1" clearance between the left rear tractor tire and mower frame or
tongue.
2. Stop and completely shut down the tractor. Place the tractor in Park and apply the Parking Brake before
dismounting.
3. Check the CV joint at this maximum turning radius by holding the driveline yoke above the PTO shaft and then
angle the CV joint to its maximum angle. A minimum difference of 10 degrees between the center line of the
yoke and the PTO shaft must be maintained to ensure the joint will not be over angled. If the joint cannot be
angled at least 10°, there is a potential problem of over-angling the joint while making sharp turns.
4. Solutions: To ensure the joint is not damaged, check the following:
-Check the drawbar length to ensure that it is at the proper length for the RPM speed of the mower.
-Move the tractor rear tires wider apart to limit the tractor turning radius.
-Position the mower at multiple angles and perform the above procedure. Determine the sharpest turning
radius that maintains a safe operating angle and note this position to the operator.

DANGER!
Do not turn so sharp or lift mower so high to produce a severe "knocking" of the Driveline
which will cause accelerated wear and breakage of drive train components and could result
in possible injury from the separated Driveline sections. (SRM-4)
