the tractor and cutter 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 cutter driveline.

Move the tractor rear tires wider apart to limit the tractor turning radius.
Position the cutter 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.
