PRE-MaINTENaNCE & REPaIR STEPS
prior to performing any repair or maintenance
work on your CHOPPeRRR, make sure that the
following steps are aLWaYS followed:
1. Visually verify that the lock-down pins are fully
engaged through the quick attach.
2. Release the pressure on the rotary cutter’s
hydraulic hoses.
3. turn the skid steer loader engine off.
4. Disconnect the hydraulic hoses that connect
to the skid steer loader.
BlaDE REMOVal
1. Follow all steps in the “Pre-maintenance &
Repair Steps” at the top of this page.
2. SLOWLY rotate the blade carrier until the
blade-attaching nut is aligned in the access
hole.
3. From the top of the deck, insert a socket
through the access hole onto the blade nut.
Remove the nut and insure that the blade
drops to the ground. Repeat the process for
the remaining blades.
4. after the nuts have been removed and the
blades have dropped, back up the skid
steer loader and CHOppERRR to retrieve the
blades.
5. after retrieving the blades, lower the
CHOppERRR back to the ground and shut the
skid steer loader engine down.
6. Inspect the blades for damage and deter-
mine if the blades need to be sharpened or
replaced.
Safety Note: When sharpening or replacing the cut-
ting blades, all blades must be either sharpened or
replaced to ensure proper blade balancing. NEVER
mix sharpened blades with new blades.
BlaDE INSTallaTION
1. Follow all steps in the “Pre-maintenance
& Repair Steps” at the top of this page.
2. tilt the front of the CHOPPeRRR up.
3. Securely position a 4” x 4” post, or equivalent
strength strut, under the front of the CHOP-
pERRR and SLOWLY rotate the blade carrier
until the blade-attaching nut is aligned in the
access hole. In lieu of using a 4” x 4” post or
other strut, the rotary cutter 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 appro-
priate strength item.
4. Insert the bolt up through the hole in the
blade and the blade holder. Insert the lock-
washer and nut through the access hole and
hand-tighten.
5. use the socket to finish tightening the nut
through the access hole that is located on top
of the deck. The nut should be tightened with
a torque wrench to 200 ft-lbs.
6. Carefully remove the 4” x 4” or other strut and
lower the CHOppERRR to the ground.
