Blade Holder Removal &
Installation
Removal:

the way back to place the attachment
in a near vertical position. Secure the
front of the cutter with an overhead
hoist or prop a 4” x 4” under the front

Be cautious
during the following step. The blade
cutter could fall resulting in Minor
or Serious Injury. Stand to the side.
Remove cap, cotter pin and castle
nut that secure the holder to the
gearbox shaft. If holder cannot be
removed, start the skid steer and
place the cutter level and jar the
cutter on the floor or ground surface.
The holder should separate from the
gearbox flange. Repeat if necessary.
