Now that you have set up your chipper shredder
for operation, get aquainted with its controls and
features. These are described below and illustrated
on this page. This knowledge will allow you to use
your new equipment to its fullest potential.
Chipper Chute
Allows twigs and small branches up to 3" in diam-
eter to be fed into the impeller for chipping. See
Figure 9.
Hopper Assembly
Allow leaves and small branches up to 1/2 diameter
to be fed into the impeller for chipping and shred-
ding. Material can be raked into hopper assembly
by lowering the hopper assembly. See Figure 9.
Release Rod
The release rod is located on the impeller bracket
assembly and it is used to release or lock the hop-
per when raising or lowering. See Figure 9.
Tow Bar (if Equipped)
Use the tow bar to tow the chipper shredder behind
a tractor to a job site. See Figure 9.
