The types of Safety Sign and locations on the equipment are shown in the illustration below. Good safety requires
that you familiarize yourself with the various Safety Signs, the type of warning and the area, or particular function
related to that area, that requires your SAFETY AWARENESS.
REMEMBER: If Safety Signs have been damaged, removed, become illegible or parts replaced without Signs, new
Safety Signs must be applied. New Safety Signs are available from your authorized distributor or factory.

Remove driveline shield bell. (Refer to page 19 for
instructions.)
Make sure the input shaft of the gearbox is greased.
This reduces the chance of the PTO shaft yoke from
galling to the input gearbox shaft if the shear bolt should
break.
Rotate driveline to align holes in yoke and shaft. Install
shear bolt and secure with locknut. Replace driveline
shield bell.
Disconnect driveline from tractor PTO.
It is necessary to gain access to bottom side of cutter
for blade removal. Raise cutter and block securely.
Align crossbar (3) with blade access hole in the cutter
deck. Remove nut (1) and lockwasher (2) then carefully
drive bolt (5) out of crossbar.
Insert blade bolt (5) through blade, align key on blade
bolt with keyway in blade beam and push blade bolt
through blade beam. Insert lockwasher (2) and nut (1)
through blade access hole in the cutter deck, install on
bolt (5) and tighten to 350 lbs.-ft.
Repeat for opposite blade.
Sharpen both blades at the same time to maintain bal-
ance. Follow original sharpening pattern. Do not sharpen
blade to a razor edge, but leave at least a
1 / 16 ” blunt edge.
Do not sharpen back side of blade.
Rotate blade beam (3) and repeat for opposite blade.
Always replace or sharpen both blades at the same
time.
Inspect blade bolt (5) for nicks or gouges; replace if any
are found. Insert bolt through blade. Blade should swivel
on bolt. Determine cause if it does not and correct.
Align blade beam (3) with blade access hole in the cut-
ter frame. Apply a liberal coating of Never Seez ® or
equivalent to blade bolt and blade beam hole. Make sure
blade is offset away from cutter.
Never Seez is a registered trademark of the
Never Seez Corporation.
W A R N I N G !
FAILURE TO USE CORRECT SIZE SHEAR BOLT
MAY CAUSE PERSONAL INJURY OR DEATH.
W A R N I N G !
FAILURE TO INSTALL RETAINING CLIP WILL
ALLOW DRIVELINE TO SWING FREELY IF BOLT IS
SHEARED CAUSING POSSIBLE INJURY OR DEATH.
IMPORTANT
If blade bolt (5) is seized in blade beam and extreme
force will be required to remove it, support blade
beam from below to prevent gearbox damage.
IMPORTANT
When sharpening blades, grind each blade the
same amount to maintain balance. Replace blades in
pairs. Unbalanced blades will cause excessive vibra-
tion which can damage gearbox bearings. Vibration
may also cause structural cracks to cutter.
IMPORTANT
Always use approved 1 / 2 ” NC x 3” grade 2 shear bolt
as a replacement part. Using a hardened bolt or
shear pin may result in damage to driveline or
gearbox.
IMPORTANT
Blade beam rotation is counter-clockwise when
looking down on cutter. Be sure to install blade cut-
ting edge to lead in counter-clockwise rotation.
