REPLACING BLADES
When replacing, changing, 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 both blades at the same
time and NEVER try to weld or straighten damaged blades, as loss of blade integ-
rity may result.
Removing Blades:
1.
With unit securely blocked off the ground and hydraulic couplers discon-
nected, loosen the capscrews on the blade access cover and swing cover
open.
WARNING! Avoid serious injury. Lower the rotary cutter to the ground, set
the parking brake, stop the skid-steer engine, and remove the
key before leaving the operator's seat. If unit must be left
raised for maintenance, block the unit securely to prevent
accidental release of the lifting mechanism. Disconnect the
hydraulic couplers.
2.
Position one of the blades under the
access panel and remove the cotter
pin and special nut. You can now
remove the blade mounting bolt and
the blade.
3.
Repeat step #2 for the remaining
blade.
Installing Blades:
1.
With unit securely blocked off the
ground and hydraulic couplers dis-
connected, loosen the capscrews on
the blade access cover and swing
cover open.
2.
Position the blade with the key of the
mounting bolt in alignment with the key
way, 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
cotter pin.
3.
Repeat step #1 for the second blade.
