7.10 Shredder Knives
Observe shredder knife operation at each use. Sharpen every
50 hours of operation.
The shredder rotor has three sets of swinging knives. Each knife
has a beveled edge that cuts, chops and mulches material as it
moves around the rotor compartment through the chop block.
The chop block helps to break the material into smaller pieces
and turn it into mulch.
The sized opening in the divider at the top of the rotor keeps the
material inside the rotor housing until it becomes fine enough
to move through to the rotor paddles and expelled out the
discharge chute.
The shredder knives need to be sharp for the best performance.
Periodic inspection is recommended.

Shredder Knives, Changing
1. Open the upper rotor housing.
2. Manually turn the chipper rotor plate so that one set of
shredder knives is fully exposed.
3. Loosen the hammer retainer pin (3) that holds the set of
shredder knives and spacers to the shredder plate.
4. Slowly remove the bolt while catching the knives and
spacers as they become free.
5. Reverse the knife or replace with a new or sharpened knife.
When installing knives, make sure the sharpened knife edge
faces the direction of rotation (indicated by a decal on the
housing).
IMPORTANT! Make sure the knives and spacers are
installed in the correct sequence. Improper installation
decreases performance.

rotate freely.
