WARNING! Avoid serious injury. Lower the brush cutter so both skid shoes are on the
ground, set the parking brake, stop the skid steer engine, and remove the
key before leaving the operator's seat. Be sure all rotation has stopped
before making any adjustments or repairs. If unit must be left raised for
maintenance, block the unit securely to prevent accidental release of the
lifting mechanism. Disconnect the hydraulic couplers.

REPLACING BLADES (GSE SERIES CUTTERS ONLY - 20-34 GPM)
When replacing, or sharpening the blades, the unit must be blocked securely off the
ground to gain access to the blades.
The blades should be inspected regularly (every 8 hours) to ensure they are sharp,
tightened correctly, and intact. Always replace all three blades at the same time and NEVER try
to weld or straighten damaged blades, as loss of blade integrity may result.
Removing Blades:
1. With unit securely blocked off the ground and hydraulic couplers disconnected, loosen
the capscrews on the blade access cover and swing cover open. See Figure #1
2. Position one of the blades under the
access panel and remove the roll pin
and special nut. You can now re-
move the blade mounting bolt and the
blade.
3. Repeat step #2 for the remaining
blades.
Installing Blades:
1. With unit securely blocked off the
ground and hydraulic couplers
disconnected, loosen the capscrews
on the blade access cover and swing
cover open.
2. Position the blade with the hex in
alignment with the hex profile in the
carrier, and either prop up in place or
have an assistant hold in place while
the special nut is installed onto the
bolt through the blade access panel.
Torque nut to 450 ft. lbs. and install
roll pin.
3. Repeat step #1 and #2 for the
remaining blades.
