hopper.
• With the vibration dampeners in the hopper mount holes from step 1, place the hopper on top of the unit. NOTE:
the slanted side of the hopper faces the discharge end of the shredder/chipper. Align the holes in the side plates
with the vibration dampeners.
• Push the four bolts up through the side plates and thread them into each vibration dampener until one or two
threads appear. Put the locknuts in place on top of the bolts coming up through the vibration dampeners. Hold the
locknut with a wrench and tighten the bolt until two threads are completely through the nut. DO NOT OVER
TIGHTEN AS THIS WILL DAMAGE THE VIBRATION DAMPENER AND POSSIBLY LEAD TO FURTHER
DAMAGE TO YOUR MACHINE.
11
INSTALLATION
• Many tractors permit direct mounting to the lower support pins on the frame of the shredder/chipper. If the lower
hitch arms on your tractor do not have enough inward adjustment to attach to the lower support pins, a pair of pin
extensions may be required to allow proper mounting of the shredder/chipper to the tractor.
• The P.T.O. drive shaft provided with this machine is sized to fit a standard category 1 P.T.O. (1 3/8” x 6 spline).
• The P.T.O. shaft on the tractor that is to use this shredder/chipper must rotate clockwise
P.T.O. from the rear of the tractor. If the P.T.O. rotates counterclockwise, you must have your tractor modified by
installing a gear box to reverse the direction of rotation.
• Depending on the mounting dimensions of the tractor, it may be necessary to have your dealer or yourself modify
the length of the P.T.O. drive shaft that is included with this shredder/chipper. Instructions follow for this
procedure.
• This machine is designed to operate at 540 RPM only. Do not operate at a faster speed that may cause serious
injury to the operator or bystanders and could cause damage to the machine that will not be covered under
warranty.

14
SECTION III - OPERATION
THIS TRACTOR SHREDDER/CHIPPER ATTACHMENT HAS BEEN DESIGNED TO OPERATE
ON CATEGORY 1 TRACTORS.
THIS MACHINE IS DESIGNED TO OPERATE AT 540 RPM ONLY!
DO NOT OPERATE AT A FASTER SPEED. THIS CAN CAUSE SERIOUS INJURY TO THE
OPERATOR OR BYSTANDERS AND COULD CAUSE DAMAGE TO THE MACHINE THAT
WILL NOT BE COVERED UNDER WARRANTY.
THE SHREDDER/CHIPPER IS DESIGNED TO BE RUN WITH THE WEIGHT OF THE UNIT ON
THE GROUND. SHREDDING OR CHIPPING WITH THE UNIT OFF THE GROUND CAN
RESULT IN INJURY TO YOURSELF OR OTHERS.
Operation Notes
• To activate the shredder/chipper, engage the P.T.O. with the tractor running at idle. Gradually increase
engine speed until you achieve a P.T.O. speed of 540 RPM.
• Proper rotor speed is 2200 RPM +/- 200 RPM.
• When viewed from the operator zone, the rotor and flywheel turn in a clockwise direction. This rotation pulls
branches into the shredder/chipper.
• Always wear protective gloves and safety glasses during operation of the shredder/chipper.
• If it becomes necessary to push material into the chipper hopper, only use a wood stick, never your hands or
anything steel.
• Never assume you know where the knife is. You don’t know where it is. Always keep hands out of all feed
hoppers.
• Keep area of discharge clear of people, animals, buildings, glass or anything else that will obstruct clear
discharge, cause injury or damage.
• If the cutting mechanism strikes a foreign object or if your machine should start making an unusual noise or
vibration, immediately stop the tractor and wait for all moving parts to come to a complete stop. After the
machine has come to a complete stop proceed as follows:
• Inspect for any damage.
• Repair or replace any damaged parts before restarting and operating the machine.
• If the machine should start to vibrate abnormally, immediately stop the tractor and wait for all moving parts to
come to a complete stop and inspect for the cause. Vibration is generally a warning sign of trouble.
• Disengage the P.T.O. drive shaft when leaving the operating position.
• Disengage the P.T.O. when moving the shredder/chipper.
• When feeding material into this equipment, be extremely careful that pieces of metal, rocks, or other foreign
objects are not included. Personal injury or damage to the machine could result.
• Adjust the baffle plate to direct the discharge material down and away from the shredder/chipper. The
discharge end of the machine has three holes for different discharge direction.
• If you shred or chip without any type of screen in place, be certain the baffle plate is held away from the rotor
with one of the screen and baffle rods. Failure to do this will allow the baffle plate to swing backward into the
grinding chamber and become damaged by the rotation of the rotor and hammers.
15
SECTION IV – SHREDDING & CHIPPING
THIS SHREDDER/CHIPPER WAS DESIGNED FOR SHREDDING LEAFY GARDEN OR
ORGANIC MATERIAL AND CHIPPING LIMBS OR BRANCHES. NEVER USE THIS MACHINE
FOR ANY OTHER PURPOSE AS IT COULD CAUSE SERIOUS INJURY.
CONTACT WITH INTERNAL ROTATING HAMMERS WILL CAUSE SERIOUS PERSONAL
INJURY. DO NOT PUT HANDS, FACE, FEET OR CLOTHING INTO THE SHREDDER HOPPER,
CHIPPER CHUTE, DISCHARGE OPENING OR NEAR THE DISCHARGE AREA AT ANY TIME.
MAINTENANCE AND SERVICE SHOULD ONLY BE PERFORMED AFTER THE TRACTOR
ENGINE IS OFF, THE P.T.O. DRIVE SHAFT IS DISCONNECTED, AND ALL MOVING PARTS
HAVE COME TO A COMPLETE STOP. USE ONLY A WOODEN STICK TO CLEAR JAMMED
MATERIAL AFTER ALL MOVING PARTS HAVE STOPPED COMPLETELY.
SAFETY FIRST
• Always wear protective gloves and safety glasses during operation of the shredder/chipper.
• Never allow your hands or any part of your body or clothing inside the feed hoppers or
discharge area of the shredder/chipper.
• Keep all protective guards and warning labels on the machine and in good working
condition.
• Always stand clear of the discharge area when the shredder/chipper is running.
• Keep your face and body back from the feed hoppers to avoid being struck by any material
that may bounce back.
• Keep proper balance and footing while operating the shredder/chipper.
• If it becomes necessary to push material into the feed hoppers, only use a wood stick, never
your hands or anything steel.
• Never assume you know where the chipper knife is. You do not know where it is.
• Keep area of discharge clear of people, animals, buildings, glass or anything else that will
obstruct clear discharge, cause injury or damage. Wind can also change discharge
direction, so be aware.
• Always keep hands out of the feed hoppers.
• Never operate the shredder/chipper without the chipper hopper in place.
• Do not transport the shredder/chipper with the P.T.O. engaged.
PROCESSING MATERIAL
• Your shredder/chipper can process dry or green material.
• Green material will process quicker and easier than dry material.
• Soft wood processes easier the hard wood.
• Your operator experience will teach you how different materials shred and chip.
• Your operator experience will teach you how fast you can process different materials.
• Most materials process well with the standard screen.
16
• When chipping branches, sometimes a tail will be left at the end of a branch. To avoid this,
rotate the branch as it is fed into the chute.
• Rotating the branch as you feed it into the machine will improve chipping performance.
• Optional screens are available for both greater and less reduction of the material being
processed through the shredder hopper.
USING THE SHREDDER HOPPER
• The shredder hopper is located on the top of the unit and is the opening into which all materials to be shredded
should be fed. Most organic materials can be shredded. A flex guard, or blowback shield is secured to the
hopper. Material must be pushed past this flap using a wooden stick in order to enter the main chipper-shredder
chamber where revolving steel hammers do the shredding. The blowback shield is an important feature. It
prevents kickback of materials! Do not use your machine unless the blowback shield is securely fastened
in place.
• Due to the wide variety of materials that can be shredded, and their very different physical characteristics, only
feed limited quantities of any material into the hopper at first. The amount and length of material can be increased
if you find that the material is being processed without any difficulty. Your judgment and operator experience is
very important. Be sure not to overload the machine by feeding too much material into the hopper at one time. If
you hear the RPM’s decreasing, stop feeding material into the machine at once. Do not resume feeding the
machine until it has returned to full speed.
• The maximum diameter of material that can be shredded is 1 ½”. Any larger material should be fed through the
chipper-hopper. Material larger than 1 ½” can cause serious damage to any of the internal parts of the chippershredder chamber. The unit should be inspected after every use for bent hammers, missing spacers, damage to
the screen or any other obvious problems. If damage occurs, the rotor assembly can become unbalanced causing
excessive vibration. If used in this state, damage can occur. Do not use the machine if vibration is present.
Vibration is generally a warning sign of trouble.
• Several small branches can be fed into the shredder-hopper at once providing their combined diameter is less
than 1 1/2”. Branches longer than three feet should be cut to make them more manageable. Green materials
should be allowed to dry, or processed in small batches with dry materials to avoid winding around the rotor
assembly.
MATERIALS BEST SUITED FOR SHREDDING
• Leaves
• Roots
• Grass clippings
• Straw
• Hay
• Small branches
• Flowers
• Soil
• Garden debris
• Hedge clippings
• Kitchen Waste
• Manure
• Corn Stalks
• Palm frond tops
• Potato vines
• Tomato vines
• Paper
NOTE - The hammers within the chipper-shredder chamber can tug suddenly at material
being fed into the shredder-hopper. Do not hold on tightly to branches and vines, and don’t
feed material straight down into the hopper with your arm pointing downward toward the
opening. Instead, keep your arms parallel to the ground and several inches above the top
edge of the hopper.
17
USING THE CHIPPER HOPPER
• This chipper-hopper is mounted on the side of the machine and is designed to chip the larger, heavier materials
that the shredder-hopper isn’t designed to handle. Branches fed into the chute are turned into “chips” by the
revolving chipper knife mounted on a flywheel. The chipper-hopper can chip branches and vines ranging in size
from 1” to 4 ½” in diameter. Cut your materials into manageable lengths before feeding them into the chipper.
Note: The chipper hopper must be securely bolted to the side of your equipment before using the
machine!
• The chipper is designed to draw the complete limbs in through the chipping area. Do not force material into the
chipper. If the machine does not self-feed, the chipper knives need replaced or sharpened or the gap between the
knives and the wear plate needs adjusting.
• Extremely hard knots will not process very well. Short stubs that have not self-fed through the chipper can be
pushed through with the next branch to be chipped. DO NOT THROW REMAINING STUBS OR UNCHIPPABLE
KNOTS INTO THE SHREDDER-HOPPER. DAMAGE WILL RESULT.
• Cut chipping material into manageable lengths of no more than five or six feet long before chipping them.
• Overloading the shredder/chipper will cause the rotor speed to decrease. If you hear the RPM’s decreasing, stop
feeding material into the machine until the machine has returned to full speed.
• Normally the branches will feed themselves into the chipper-hopper if trimmed to an appropriate size. Once the
self-feeding starts, release the branch quickly to avoid ripping from your hands.
MATERIALS BEST SUITED FOR CHIPPING.
• Branches, vines or stalks from 1 ½” to 4 ½” in diameter.
18
USE COMMON SENSE WHEN USING YOUR SHREDDER/CHIPPER.
• LEARN TO RECOGNIZE THE CHANGE IN THE SOUND OF YOUR MACHINE
WHEN IT IS OVERLOADED.
• BECOME FAMILIAR WITH SUCCESSFUL OPERATING CONDITIONS AND
AVOID THOSE THAT CAN OVERLOAD AND DAMAGE THE MACHINE.
• IF THE MACHINE BECOMES JAMMED BY OVERLOADING OR ANY OTHER CAUSE,
STOP THE MACHINE IMMEDIATELY.
• IF YOU JAM THE MACHINE AND DO NOT DISENGAGE THE P.T.O., IT CAN DAMAGE
THE MACHINE. THIS DAMAGE CAN BE COSTLY AND IT MAY NOT BE COVERED
UNDER WARRANTY. FOR THIS REASON, IT IS IMPORTANT THAT YOU
IMMEDIATELY DISENGAGE THE P.T.O. IF THE MACHINE BECOMES JAMMED.
• ONLY YOUR OPERATOR EXPERIENCE WILL TELL YOU HOW FAST TO FEED
MATERIAL TO BE PROCESSED.
• CHECK TO SEE THAT THE FLYWHEEL WILL TURN FREELY BEFORE YOU START
THE SHREDDER/CHIPPER.
• VISUALLY CHECK CHIPPER KNIFE FOR DAMAGE EACH TIME YOU USE YOUR
SHREDDER/CHIPPER.
• CHECK KNIFE CONDITION, WEAR PLATE CONDITION, GAP SETTING AND THE
NUTS AND BOLTS THAT HOLD THE KNIFE IN PLACE FOR TIGHTNESS EVERY
8-10 HOURS OF OPERATION.
• DO NOT ALLOW PROCESSED MATERIAL TO BUILD UP WITHIN 3” OF DISCHARGE
CHUTE OPENING. MOVE SHREDDER/CHIPPER OR PILE AS NEEDED. FAILURE TO
DO THIS COULD RESULT IN UNNECESSARY JAMMING OF THE MACHINE.
• TO MOVE PILE OF PROCESSED MATERIAL, USE SPADE, RAKE, OR LONG HANDLE
TOOL. NEVER
USE YOUR HANDS OR FEET!
19
SECTION V - MAINTENANCE AND STORAGE
IMPORTANT: The knife should be checked for sharpness and the bolts attaching them to the flywheel for
tightness every 8-10 hours of operation.
IMPORTANT: Every time you perform maintenance or any kind of service or check on the knife, be sure to
check the gap between the knife and wear plate for proper setting.
If the cutting mechanism strikes any foreign object or if your machine should start making an unusual
noise or is vibrating, stop the engine and disconnect the P.T.O shaft before you:
a. Inspect and examine for damage.
1. When not in use, your shredder/chipper should be stored out of the reach of children.
2. After every 8 hours of operation, lubricate the chipper side and drive side bearings. To do this, wipe all dirt, etc.,
3. When the steel chipping knife needs replacing or sharpening, refer to the section on removal, sharpening and re-
4. Care must be exercised when sharpening the knife to maintain the correct bevel and a straight edge. Refer to
b. Repair o replace any damaged parts before restarting and operating the machine.
from the grease fittings with a clean cloth, then apply no more than 3 shots of quality general-purpose grease with
a hand-pumped grease gun. Over lubrication can also damage bearings. Also, check the bearing collar set
screws regularly to be sure they are tight. If they are loose, reset them with Loctite 243, obtainable at any
hardware store.
installation.
sharpening directions. When you install a knife, the clearance between the knife and wear plate must be checked
and set. This clearance or gap should be set to 1/16” (see figure 1).
FLYWHEEL
CHIPPER KNIFE
WEAR PLATE
1/16" GAP
Figure 1
5. To adjust this clearance, loosen the three ¼” nuts and bolts holding the wear plate in place. The wear plate can
be slid up or down (in or out) to achieve the correct gap setting. Tighten the nuts and bolts when the wear plate is
in the correct position. Be certain the flywheel rotates without hitting anything before starting the chipper.
6. If the gap between the wear plate and the knife is not set correctly, you will have excessive vibration when
chipping and the blade will seem to be dull. This should be checked every 8-10 hours of operation.
7. If at any time it becomes necessary to disassemble the chipper for repairs, the chipper disk must be re-installed in
exactly the same position on the rotor shaft.
20
REMOVAL, SHARPENING AND RE-INSTALLATION OF CHIPPER KNIFE
HOW TO REMOVE THE KNIFE
• Stop the tractor engine and disengage the P.T.O. driveshaft.
• Open the access cover on the chipper basic machine.
• Rotate the chipper disk until the three countersunk screws attaching the knife to the flywheel are visible
through the access door.
• Clean out the heads of the allen screws with an awl or sharp tool.
• Insert a 3/16” allen wrench into the heads of the screws.
• While applying pressure with the allen wrench, apply heat from a propane torch to the screws to break loose
the Loctite on the screws.
• Remove the heat once the screws have loosened.
• Remove all three allen screws in this manner.
KNIFE SHARPENING
• You should never attempt to sharpen the chipper knife freehand.
• It is extremely important that the 45-degree angle be maintained consistently for proper performance.
• The chipper knife should be taken to a machine shop for proper sharpening.
• Excessive heat generated during the sharpening process will damage knives and weaken the metal. Be sure
the knife is not overheated.
KNIFE INFORMATION
• The chipper knife should be checked routinely for sharpness.
• Using a dull knife will decrease performance and cause excessive vibration that will cause damage to the
shredder/chipper.
• How many times a knife can be sharpened is determined by how much material needs to be taken off to
sharpen or to compensate for dents or gouges.
• A new chipper knife has 5/16” measurement between the short side bevel edge and the knife mounting holes.
See figure 2.

21
• The knife should never be sharpened to the extent that more than 3/32” is taken off this measurement.
• Once this measurement is below 7/32” (see figure 3) the knife should be replaced.
• If you are unable to remove dents or gouges with these guidelines, replace the knife.

KNIFE INSTALLATION
• Clean chipper disk where knife is going to be attached.
• Visually inspect the chipper disk slot and knife mounting area and be sure they are clean and that the knife will
be able to mount flush against the chipper disk.
• Visually inspect and clean the knife.
• Apply Loctite 243 to the screws that hold the knife in place.
• Hand tighten the knife to the chipper disk. If you are installing a new knife, use the new hardware that comes
with the knife when attaching it to the chipper disk.
• Tighten the center bolt.
• Tighten the outer bolt.
• Tighten the inner bolt.
• Double-check all three for tightness one more time.
WEAR PLATE
• The wear plate should have a square edge and be free of dents or gouges.
• The wear plate can be sharpened by hand, but as with the knife, do not overheat during the sharpening
process. This will change the characteristics of the steel and it should be replaced.
• Check the gap between the knife and wear plate every time any adjustments are done to either piece, or every
8-10 hours of operation.
22
AFTER ANY BLADE OR WEAR PLATE MAINTENANCE OR ADJUSTMENT, ROTATE THE
CHIPPER DISK BY HAND. WATCH AND LISTEN CAREFULLY FOR ANY UNUSUAL NOISES,
CLICKING OR VIBRATION. IF ANY OF THESE ARE DETECTED, INSPECT THE MACHINE
FOR DAMAGE, REPAIR OR REPLACE ANY DAMAGED PARTS AND CHECK FOR ANY
LOOSE PARTS AND RETIGHTEN.
KNIVES MUST BE CHECKED AND MAINTAINED!
KNIVES MUST BE SHARP!
BE SURE TO REINSTALL THE KNIFE CORRECTLY AND DOUBLE CHECK FOR
TIGHTNESS!
HAMMERS
When the hard steel hammers of the rotor assembly become dull or round on the cutting edge, they
may be rotated or reversed. These hammers have four cutting edges that may be used before
