6. Reassemble the driveline halves and connect to tractor and rotary cutter. Raise and
lower rotary cutter again to be sure driveline does not bottom out in its shortest
position and has a minimum overlap of 6” in the longest position.
7. Install both driveline safety chains. One should be hooked in a hole on the outer
driveline yoke shield and to the tractor to restrict outer shield rotation. The second
one should be hooked in a hole on the inner driveline yoke shield and to the rotary
cutter to restrict inner shield rotation.
If determined that the driveline is too short for your tractor, contact your local dealer.
CAUTION: Always work with the driveline as straight as possible. This will
prolong its life and that of its components. It is advised not to work at an angle
greater than 15 degrees.
4.06 - Safety Shear Bolt
CAUTION: When this machine is equipped with a shear bolt driveline, for the
protection of the PTO and gearbox, never replace the shear bolt with anything
harder than a grade 2 bolt. All warranties will be void if a bolt harder than a grade
2 is used.
IMPORTANT: To install the driveline with the safety shear bolt, slide driveline yoke onto
gearbox input shaft. Install snap ring onto grove on input shaft. The snap ring is for
added security in case the shear bolt should break. Install ½”-13x3.5” grade 2 shear bolt
through yoke and input shaft and secure with ½” nut
