SECTION 2: OPERATING INSTRUCTIONS
TRANSPORTING
Note: Always disengage PTO before raising woodchipper to transport position.
1. When raising the woodchipper to transport position, be sure that driveline does not
contact tractor or implement. Adjust and set tractor lift arms height so that the driveline
does not contact implement in the fully raised position.
2. Be sure to reduce tractor ground speed when turning, leaving enough clearance so that
the implement does not contact obstacles such as buildings, trees, or fences.
3. Select a safe ground travel speed when transporting from one area to another. When
traveling on roadways, transport in such as a way that faster moving vehicles may pass
safely.
4. When traveling over rough or hilly terrain, shift tractor to a lower gear.
DETAILED OPERATING INSTRUCTIONS
The WCBX62S woodchipper is designed to cut wood products 6” in size and smaller such as
brush, branches, small trees, and lumber into small chips that can be quickly turned into mulch
or just to aid in decomposition.
1. Park tractor with woodchipper outside on a level solid surface. Make sure there is room
to discharge chips into a pile directed away from people, animals, tractor, equipment,
buildings, and operator.
2. Set tractor engine speed at an idle, place tractor gear selector in park, and set park
brakes.
3. Rotate discharge chute to discharge product in the direction desired. See “Discharge
Chute Angle” on page 23 for detailed instructions.
4. Rotate deflector chute to direct product being discharged closer or farther away. See
“Deflector Chute Angle” on page 23 for detailed instructions.

15
5. With engine speed at a low idle, engage power take-off and then slowly increase engine
speed to 540 rpm.
6. Untangle product before inserting it into the feed chute. Slowly slide one piece at a time
into the feed chute toward the rotor knives.
7. To protect oneself, do not reach past the rubber skirt inside the feed chute. Instead use a
stick or branch to lightly push on the product as needed. If tractor engine starts to slow,
stop pushing on the product. Once engine speed returns, continue push lightly on
product but at a slower speed. Do not force feed product into the chipper.
8. Once woodchipper starts to self-feed, release product and allow rotor knives to pull
product in at its own speed. If knives will not pull product in, then refer to “Product self-
feed slowly or won’t self-feed at all” in the “Troubleshooting” chart on page 28.
9. Make any necessary corrections to the discharge chute angle and deflector chute to
finalize direction and location of chip pile.
10.Never leave woodchipper with unit running. Always lower engine speed to an idle,
disengage power take-off, shut tractor engine off and remove switch key before leaving
the work area. Disengage power take-off if foreign material such as glass, metal, or rocks
enters the chipper or if other emergencies arise. Shut tractor engine off, remove switch
key, and wait for moving parts to come to a complete stop before removing foreign
material. Inspect and make repairs before putting machine back into service.
HELPFUL OPERATING HINTS
The following hints will help keep the chipper running.
1. Be careful not to feed too much product at once, feed oversize product, feed wet
product, or feed product too fast. Doing so can plug the woodchipper.
2. Alternate leafy material with a not leafy hardwood piece. Hard wood pieces help clean
out leafy material. Keep alternating leafy material with hardwood pieces until leafy
material is processed.
3. Let leafy branches dry for a couple weeks before chipping them. Dry leaves will process
better.
4. Maintaining 1-1.5mm gap between ledger bar and rotor knives will keep knives wiped off,
prevent plugging, allow product to feed better, and keep wood chipping.
GENERAL OPERATING INSTRUCTIONS
•Now that you have familiarized yourself with the Operator’s Manual, property attached
your woodchipper to your tractor and adjusted the angle of tilt correctly, you are almost
ready to begin using your WCBX62S woodchipper.
•It is now time to do a running operational safety check. If at any time during this safety
check you detect a malfunction in either the woodchipper or tractor, shut tractor off
immediately, remove switch key, and make necessary repairs or adjustments before
continuing on.
•Make sure the tractor’s park brake is engaged, the tractor’s power take-off is disengaged,
and the driveline shaft is not in a bind. Start the tractor and then back the tractor throttle
off until the engine is at low idle.
•With the tractor running at an idle speed, make sure that the rear 3-Point control arms
will lower the woodchipper from transport to working position and back without putting
the driveline into a bind. Lower the woodchipper down to ground and engage the power

16
take-off drive shaft. Check to make sure everything is running smoothly. If not, safely
shut the tractor down to make necessary corrections. If everything is in proper working
condition, you are ready to move to the work site.
•At the work site you should rotate the discharge chute to direct product away from the
operator, people, animals, equipment, and buildings. You should also adjust the deflector
chute to control the discharge product will be thrown.
•You are now ready to begin turning wood into chips. Make sure the tractor gear selection
is in park and park brakes are set. Set tractor engine rpm at a low idle and engage the
power take-off. Once the unit is running, increase power take-off speed to 540 rpm.
Dismount tractor and go to the rear to begin loading limbs and brush 4” and smaller into
the feed chute one at a time. You should release your grip once the product starts to self-
feed. Be careful not to reach past the rubber skirting in the feed chute. When necessary,
you should use a stick or board to push on objects beyond the rubber skirting. You will
immediately begin to see a generous stream of chips being rapidly ejected out of the
discharge chute to a predetermined location. If the chip pile is not developing where you
would like, then readjust discharge chute and deflector chute to redirect where the pile
will build. With a little practice, you will gain the required experience you need to help
you achieve the desired results you expect from your WCBX62S woodchipper.
•Whether you are done chipping, need to take a break, or just need to make a few
adjustments, always remember to reduce the tractor’s engine rpm, disengage the power
take-off, turn engine off, and remove the switch key.
UNHOOK WOODCHIPPER
See “Long Term Storage” on page 29 before unhooking and storing the woodchipper for long
periods or at the end of the season. Unhook woodchipper from tractor as follows:
1. See “Long Term Storage” on page 29 when storing unit for long periods or at the end of
the season.
2. Shut tractor down properly before dismounting. Refer to “Tractor Shutdown Procedure”
on page 14.
Refer to Figure 1-7 on page 15:
3. Pull back on driveline lock collar and hold while puling driveline yoke from the tractor
shaft.
4. If needed, adjust length of upper 3-Point center link until center hitch pin is loose and can
be removed.
5. Remove center safety lock pin and hitch pin from the chipper’s upper center clevis.
6. Move 3-Point link out of the way and reinstall hitch pin and safety lock pin in the chipper’s
center clevis for storage.
7. Remove linchpins form lower 3-Point hitch pins.
8. Move lower 3-Point arms out of the way and reinstall linchpins in chipper’s lower hitch
pins for storage.
9. Pull back on driveline lock collar and hold while pulling driveline yoke from the tractor
shaft. If possible, support driveline from upper center hitch pin or on a support block to
keep driveline out of the dirt.
10. If there is a slow-moving vehicle sign mounted on the back of the chipper and if it belongs
to the tractor, remove it from the chipper and insert if in the mounting bracket on the
back of the tractor.

CHECK LEDGER KNIFE CLEARANCE
To avoid serious injury or death: Knives and ledgers are sharp. ALWAYS wear gloves and eye
protection while inspecting and adjusting ledger clearance.
IMPORTANT: It is best to have two people available to check ledger knife clearance; or have in
place a way other than the pivot latch to securely
support the feed chute rotate up; or remove the
feed chute from the chipper lower frame.
Figure 3-3: View of Rotor Knife (#4) and Ledger
Knife (#5)
The knives (#4) cut best if knife ledger (#5) is
adjusted with 1mm to 1.5mm gap between
cutting edge of knives and knife ledger. The
larger the gap, the faster the product with self-
feed. Do not exceed 1.5mm gap.

18

5. Check gap between ledger knife (#5) and rotor knives (#4) as follows:
a. Manually rotate rotor (#2) until cutting edge of rotor knife (#4) is in line with top
inside edge of lower rotor housing (#16).
b. Measure and record distance between rotor knife (#4) and lower rotor housing
(#16).
c. Repeat steps 5a & 5b for the other 3 rotor knives.
d. Select the rotor knife (#4) closes to the inside wall of rotor housing (#16) and
rotate that rotor knife to be in line with ledger knife (#5).
e. Refer to Figure 3-4 on page 28: check gap between selected rotor knife (#4) and
ledger knife (#5). The gap should be between 1mm to 1.5mm and should be equal
distance along the full length of the ledger knife.
6. Manually rotate rotor (#2) one full turn to recheck all rotor knives (#4). Make sure all
rotor knives do not come in contact with the ledger knife (#5). If any rotor knife contacts
the ledger knife, then readjust ledger knife to clear that rotor knife by 1mm to 1.5mm.
7. Remove any tool or loose component that may have collected inside the rotor housing.
8. Rotate upper rotor housing (#15) closed and tighten bolt (#12) to the correct torque

NOTE: Credit card can be used to set gap. Tolerances in manufacturing vary due to weld pull. Set
closest rotor knife to ledger with 1mm shim and lock ledger in place. Rotate rotor and check all
other rotor knives for clearance.
1. Loosen bolts (#3).
2. Place 1mm to 1.5mm shim between knife edge and knife ledger. Do not exceed 1.5mm.
3. Adjust knife ledger against the shim. Hold ledger in this position to tighten bolts (#3) in
step 4 below.
4. Tighten GR8.8 ledger bolts （#3）to the correct torque. See “Bolt Torque” on page 30.
5. Continue with step 6 under “Check Ledger Knife Clearance” on page 20 & 21.
SECTION 4: MAINTENANCE AND LUBRICATION
GENERAL MAINTENANCE INFORMATION
Proper servicing and adjustments are key to the long life of any implement. With careful
inspection and routine maintenance, you can avoid costly downtime and repair.
Check all bolts and pins after using the unit for several hours and on a regular basis thereafter
to ensure they are tight and secured. Lubricate components on schedule.
To avoid serious injury or death:
•Work only in areas that are well ventilated.
•Never operate an engine in a closed area without venting the exhaust fumes.
•Exhaust fumes will cause asphyxiation and can lead to death.
•Always secure equipment with solid, non- concrete supports before working under it.
Never go under equipment supported by concrete blocks or hydraulics. Concrete can
break, hydraulic lines can burst, and/or hydraulic controls can be actuated even when
power to hydraulic is off.
•Always disengage power take-off before lifting implement up, and never operate
implement in the raised position.
•Objects can be thrown at high speed toward
•people or animals.
•Always disconnect driveline from the tractor before servicing the drivetrain and
component powered by the drivetrain. A person can become entangled in the drivetrain
if the tractor is started, and the power take-off is engaged.

20
To avoid serious injury or death:
•Do not operate woodchipper with an out-of-
•balance rotor, damaged or worn knives. Internal parts can work loose or break at high
speeds. Always replace all blades at the same time.
•Perform scheduled maintenance. Check for loose hardware, missing parts, broken parts,
structural cracks, and excessive wear. Make repairs before putting the implement back
into service.
ROTOR KNIVES
•Do not operate woodchipper with an out-of- balance rotor, damaged or worn knives.
Internal parts can work loose or break at high speeds. Always replace all blades at the
same time.
•Wear eye protection and gloves while inspecting, removing, sharpening, and replacing
knives.
•Knife bolts must be tightened to the correct torque value. Not doing so can damage the
chipper and cause bodily injury.
•Torque values for the knife bolts are provided under “Bolt Torque” on page 30.
IMPORTANT: Replace knives with original knives only. All knives must be replaced at the same
time. Not replacing knives at the same time will result in an out of –balance condition that can
contribute to premature bearing breakdown and create structural cracks in the chipper housing.
Refer to Figure 3-3 on page 20.
ROTOR KNIFE ACCESS
1. Make certain gear selector is in park and park brake is set. Disengage power take- off,
shut tractor engine off, remove switch key and wait for all moving parts to stop before
working on this machine.
2. Disconnect driveline from tractor power take-off shaft.
3. Remove bolt (#12), spring washer (#13), plain washer (#14).
4. Rotate upper rotor housing (#15) up until upper housing is opened completely. Do not
drop upper rotor housing and discharge chute.
5. When finished servicing rotor knives, rotate upper rotor housing down and secure with
bolt (#12).
ROTOR KNIFE MAINTENANCE
1. Manually rotate one of the rotor knives to the top.
2. Unscrew bolts, spring washer and plain washer as well as rotor knife.
3. Rotate the remaining rotor knives to the top and remove them.
4. Examine bolts, spring washer and plain washer as well as rotor knife for damage and
replace it with new one if needed.
5. Inspect rotor knives for wear. Reverse knife if unused cutting edge is still sharp, re-
sharpen knives if both edges are dull, and replace knives if both edges are ground so far
that the proper gap between rotor knife and ledger knife cannot be achieved.
