Equipment Operation
Using the Shredder Hopper:
The Tow-Behind Shredder can pro-1.
cess dry or green organic material.
Green material will process easier
and faster than dry material. Soft
wood processes easier than hard
wood. Rotating the branch as you
feed it into the machine will improve
performance.
The Shredder Hopper (85) is located2.
at the top of the machine and is the
opening into which all materials to be
shredded should be fed.
(See Figure Y.)

SKU 65342 For technical questions, please call 1-800-444-3353. Page 15
Due to the wide variety of materials3.
that can be shredded, and their differ-
ent physical characteristics, only feed
limited quantities of any material into
the Shredder Hopper (85) at rst. The
amount and length of material can be
increased if you nd that the material is
being processed without any difculty.
Make sure not to overload the machine4.
by feeding too much material into the
Shredder Hopper (85) at one time. If
you hear the RPM’s (speed) of the
Engine decreasing, immediately stop
feeding material into the machine. Do
not resume feeding material into the
hopper until the Engine has returned to
full speed.
The maximum diameter of material5.
that can be shredded is 1”. Any ma-
terial larger than 1” diameter should be
fed into the Chipper Hopper (6).
Several small branches can be fed into6.
the Shredder Hopper (85) at one time
providing their combined diameter is
less than 1”.
Branches longer than three feet should7.
be cut to make them more manage-
able.
8. Use safety
equipment. Always
wear ANSI-approved
safety goggles, hearing protection, and
heavy duty work gloves.
Make sure the Tow-Behind Shredder9.
is located on a dry, at, level surface
capable of supporting the weight of the
machine, materials being processed,
the operator(s), and any additional
tools and equipment.
Make sure the machine is empty of10.
material prior to starting the unit.
Start the Engine (61), and allow it to11.
run at full speed. (Refer to previ-
ous instructions in this manual for
Engine starting and operation.)
Always stand clear and to the side of12.
the Discharge Chute located at the
bottom of the machine.
Without putting your hands into the13.
Shredder Hopper (85), slowly drop
the material into the Hopper. The
machine will pull the material in auto-
matically.
(See Figure Y.)
14. Never use
your hands to feed
material into the
Shredder Hopper (85). If necessary, use
a stick to push the branches, leaves, etc.
into the Hopper. (See Figure Y.)
Do not allow processed material to15.
build up in the Discharge Chute.
This may prevent proper discharge
and can result in kickback of material
through the Shredder Hopper (85).
(See Figure Y.)
Should the machine jam during16.
use, immediately turn off the En-
gine’s Power Switch. Wait until the
machine completely stops. Allow
the Engine (61) to completely cool.
Remove the Engine’s Spark Plug
Wire. Clear the jam. Re-install the
Spark Plug Wire. Then restart en-
gine and resume operation.
When nished, turn the Engine’s 17.
Power Switch to its “OFF” position.
Wait until the machine completely
stops. Allow the Engine to com-

pletely cool. Remove the Engine’s
Spark Plug Wire. Then clean out the
interior of the machine and its Dis-
charge Chute.
Using the Chipper Hopper:
The Chipper Hopper (6) is located1.
on the side of the machine and is
designed to chip the larger, heavier
materials that the Shredder Hopper is
not designed to handle.
(See Figure Y.)
The Chipper Hopper (6) can chip2.
branches and vines ranging in size
from 1” to 3” in diameter.
(See Figure Y.)
Make sure to cut the material into3.

before feeding them into the Chipper
Hopper (6).
Do not force material into the Chip-4.
per Hopper (6). If the machine does
not chip well, have a qualied service
technician sharpen or replace the
Chipper Knives and/or adjust the gap
between the Knives and Wear Plate.

very well. Short stubs that have not
self-fed into the Chipper Hopper (6)
can be pushed through with the next
branch to be chipped. Do not throw
remaining stubs or unchippable
knots into the Chipper Hopper.
Damage to the machine will result.
(See Figure Y.)
If branches are larger than 1” diam-6.
eter, feed only one branch at a time
through the Chipper Hopper (6).
(See Figure Y.)
Branches smaller than 1” diameter 7.
can be bundled together and fed
through the Chipper Hopper (6) at

der will cause the Engine (61) RPM’s
(speed) to decrease. If you hear the
Engine RPM’s decreasing, stop feed-
