BlaDE HOlDER REMOVal
1. Follow all steps in the “Pre-maintenance
& Repair Steps”. see page 5
2. tilt the CHOPPeRRR deck at a near vertical
angle. Carefully and securely position a 4” x
4” post, or equivalent strength strut, under
the rear portion of the CHOppERRR deck. In
lieu of using a 4” x 4” post or other strut, the
front portion of the rotary cutter’s deck can
be leaned against the trunk of a large tree
and allowed to stay in such position until the
blade holder is removed. If the latter method
is chosen, remember to scotch or chock the
skid steer loader’s tires with a brick, log or
other appropriate strength item.
3. Remove the cotter pin and castle nut that
secures the blade holder to the gearbox. Be
careful in performing this step, as it is possible
that the blade holder will fall and cause bodily
damage.
4. Restart the skid steer loader’s engine and
slowly but firmly strike (if required) the bottom
portion of the rotary cutter’s deck on the
ground. Repeatedly strike the rotary cutter on
the ground until the blade holder falls off.
