Chipper/Shredder

Chipping
• Select limbs that are up to 5 inches in
diameter; trim branches that will not
fit into the chipper chute. Smaller
branches can be bunched and ran
through together.
• Place limb, butt end first, into the chip-
per chute until it touches the chipper
knives.
The feed rate of the limb into the chip-
per depends on the material and
sharpness of the chipper knives.
The operator can feed the limb by
alternately inserting and retracting the
limb or continuously feeding it, so long
as it doesn’t kill the engine or the trac-
tor. By rotating the limb you can im-
prove the cutting action of the chipper.
• The chipping knives will become dull
at varying times depending on the
wood material used. Periodic sharpen-
ing of knives will be required. Refer to
the Service & Maintenance section for
sharpening instructions.
Shredding
• Feed material such as grass, leaves,
garden refuse, and branches up to
1” in diameter and 36” long into the
shredder hopper.
• Use a leaf tamper, branch or similar
object to push light material into shred-
ding chamber.
• Feed material at an even pace to
avoid plugging or lugging of the Chip-
per/Shredder. If the shredder should
become plugged, refer to the service
section of the manual before clearing
plugged material. Branches or material
that cause plugging or slow opera -
tion should be fed at a slower pace to
avoid plugging.
SAFETY WARNING!
• Never leave the machine unattend-
ed, or attempt service or inspec-
tion unless the machine has come
to a complete stop, the engine has
been shut off, and the spark plug
has been disconnected.
• On PTO units, make sure the PTO
and the tractor engine has been
shut off and the machine has come
to a complete stop.
NOTE: To avoid entanglement with material
going into the shredder hopper it is suggested
to use a throwing motion when feeding mate-
rial.
