DESCRIPTION
DESCRIPTION
This Chipper/Shredder is designed to grind, shred, and chip a variety of materials into a useable
processed material to enrich, beautify and landscape. Mounted on the front of the Steiner 4-wheel
drive articulated frame tractor enables the chipper/shredder to be used in a variety of locations.
Small materials such as leaves, yard and garden debris (cornstalks, plants, prunings, vines, etc.) can
easily be processed through the shredder inlet. Sticks and branches should be limited to 1-1/2 inches in
diameter and no longer than 24 inches to avoid excess whipping and wrapping. The processed material can
be placed in a compost pile or spread on the ground as mulch, giving a professionally landscaped look.
The chipper inlet can chip branches up to 4 inches in diameter. Several small branches can be grouped and
fed into the chute together. The chipper can reduce a pile of branches and brush into useful and attractive
decorative landscape chips.

CHIPPER/
SHREDDER
OPERATION
SHREDDING INSTRUCTIONS
1. Place material to be shredded (leaves, garden
debris, sticks and branches up to 1-1/2" diameter
and 24" long, etc.) into the hopper.
2. Feed material evenly into the shredder so that
the tractor does not lug down or the shredder
become clogged. If necessary, use the hopper
lid to push the material through the inlet guards.
If the machine becomes plugged it may be
necessary to remove the discharge shield and
screen to clean rotor. Branches or items that
plug or cause the machine to stall should be fed
slowly and carefully.
3. If equipped with a blower, it is recommended
to alternate between dry and green material to
avoid blower plugging.
CHIPPING INSTRUCTIONS
1. Select limbs that are up to 4 inches in diameter.
Trim side branches that do not t into the chipper
chute. Small diameter branches can be held
together in a bundle and fed in simultaneously.
2. Place limb, butt end rst, into the chipper chute
until it contacts the chipper blades. The actual
feed rate of the limb into the chipper will depend
on the type of material fed, and sharpness of the
cutting blades. Alternately insert and retract the
limb or insert continuously at a rate that will not
stall the tractor. Rotating the branch as it is fed
will improve cutting action. The chipping knives
will dull with use and require periodic sharpening.
Refer to Page 11 for instructions to sharpen
chipper knives.
STOPPING INSTRUCTIONS
Do not leave machine unattended, or attempt any
inspection or service unless the PTO is disengaged
and tractor engine is shut off. Allow machine to
come to a complete stop.
To stop machine proceed as follows:
1. Move tractor throttle to slow position.
2. Disengage PTO and shut off tractor engine.
3. Allow machine to come to a complete stop.
NOTE: The rotor is heavy and has inertia that will
make the rotor continue to turn for some time after
the tractor has been shut off. The stopping time can
be shortened by inserting a branch in the chipper
chute so that it contacts the knives and slows the
rotor to a complete stop.

MAINTENANCE AND ADJUSTMENTS
Before inspecting or servicing any part of the
machine, disengage PTO and make sure all
moving parts have come to a complete stop.
The chipping knives and shredding sections
are sharp! Use care when working on machine
to avoid injury.
SHARPENING CHIPPER KNIVES
It is recommended that the chipper knives are
sharpened every 5 to 15 hours of chipper operation,
depending on the type of wood fed into the chipper.
To remove the chipper knives for sharpening, rst
remove the discharge shield and the discharge
screen. Remove the two 5/16 inch retaining bolts
and pull the screen outward. Remove the knife
access cover. Rotate the rotor so that the bolts
holding the chipper knife are accessible. Remove
the two bolts holding the knife and the knife itself.
Repeat for all 4 knives.
Grind the knife at 45 degrees. (See Figure A) The
knives can be ground on a bench grinder or by a
professional. Be careful when grinding so that the
knife material does not get too hot and change
color, this will remove the knife’s special heat
treated properties. Use short grinding times and
cool with water. Try to remove an equal amount
off each knife to maintain balance. Replace the
chipper knives and tighten bolts to 20 foot pounds.
Replace the discharge screen.
ADJUSTING KNIFE CLEARANCE
The chipper knife should clear the chipping block
by 1/8 inch. (See Figure B) To adjust the knife
clearance, proceed as follows:
A. Remove the belt shield, discharge shield, and the
discharge screen. Remove the shaft cover on
the front side.
B. Loosen the two set screws holding the set collar
at the front rotor bearing. Loosen the set screws
holding the lock collars on the front and rear rotor
bearings.
C. Use a punch and hammer and tap the collars in
a direction opposite shaft rotation so they can
rotate freely.
D. Using a soft face mallet, tap the end of the
rotor shaft to obtain 1/8" clearance between
the chipper knife and the chipper block. (See
Figure B) Knife clearance can be checked at the
chipper inlet chute. Rotate the rotor and check
the clearance on all chipper knives.
E. When the clearance has been set, tighten the
eccentric lock collars on the bearings by rotating
them in the direction of shaft rotation. Using a
punch and hammer, “set” them with a positive
hammer tap. Tighten the lock collar set screws.
Slide the set collar against the front bearing lock
collar and tighten the two set screws.
F. Check the double drive belts for proper
alignment. It may be necessary to move the
pulley on the rotor shaft an equal distance the
rotor was moved.
G. Make sure all set screws are tight and replace
discharge screen and all shields which were
removed.

SHREDDER SECTIONS
The serrated self sharpening shredder sections are
designed to offer long life and can be reversed if they
become dull. To remove or replace the sections,
proceed as follows:
A. Remove discharge shield, discharge screen and
knife access cover.
B. Work with one section shaft at a time. Remove
the #10-24 bolt from the section shaft. The shaft
can be removed through the access hole.
C. Remove sections and section spacers. Be
careful to keep track of the order the spacers
were installed on the shafts so they can be
returned to the original locations. If the spacers
are not installed properly, the rotor will be out of
balance and also will not have proper shredding
action.
D. Reverse or replace sections and reassemble
into the rotor. Reinstall #10-24 bolt and locknut
through spacer and torque to 36 inch pounds.
E. Complete service of all 6 shafts and replace
the knife access cover, discharge screen and
discharge shield.
BELT REPLACEMENT
Check the condition of the double drive belts every
30 hours of operation or annually, whichever occurs
rst. Only replace belts in sets.
To replace belts proceed as follows:
A. Disengage PTO and stop engine.
B. Remove belt shields.
C. Remove belt idler spring and remove belts from
pulleys.
D. Remove 4 bolts attaching hitch assembly to main
frame and completely remove belts.
E. Place new belts around the hitch frame and
attach the hitch assembly to the main frame.
F. Position belts on the pulleys and attach the idler
arm spring.
G. Check the attachment drive belt and replace if
needed. Replace belt shields.
