GENERAL INFORMATION
The purpose of this manual is to assist you in operating
and maintaining your grinder. Read it carefully. It fur-
nishes information and instructions that will help you
achieve years of dependable performance. These in-
structions have been compiled from extensive eld
experience and engineering data. Some information
may be general in nature, due to unknown and varying
operating conditions. However, through experience
and these instructions, you should be able to develop
procedures suitable to your particular situation.
■Some illustrations in this manual show the
grinder with safety shields removed to provide
a better view. The equipment should never be
operated with any safety shielding removed.
The illustrations and data used in this manual were
current at the time of printing. However, due to possi-
ble inline production changes, your machine may vary
slightly in detail. We reserve the right to redesign and
change the machines as may be necessary without
notication.
Throughout this manual, references are made to right
and left directions. These are determined from the op-
erator’s position in the tractor seat.

TRAINING
■Safety instructions are important! Read all at-
tachment and power unit manuals; follow
all safety rules and safety decal information.
(Replacement manuals and safety decals are
available from your dealer. To locate your
nearest dealer, check the Dealer Locator at
www.WoodsEquipment.com, or in the United
States and Canada call 1-800-319-6637.) Failure
to follow instructions or safety rules can result in
serious injury or death.
■If you do not understand any part of this manual
and need assistance, see your dealer.
■Know your controls and how to stop engine and
attachment quickly in an emergency.
■Operators must be instructed in and be capa-
ble of the safe operation of the equipment, its
attachments, and all controls. Do not allow any-
one to operate this equipment without proper
instructions.
■Keep hands and body away from pressurized
lines. Use paper or cardboard, not hands or
other body parts to check for leaks. Wear safe-
ty goggles. Hydraulic uid under pressure can
easily penetrate skin and will cause serious in-
jury or death.
■Make sure that all operating and service person-
nel know that if hydraulic uid penetrates skin,
it must be surgically removed as soon as possi-
ble by a doctor familiar with this form of injury
or gangrene, serious injury, or death will result.
CONTACT A PHYSICIAN IMMEDIATELY IF FLUID
ENTERS SKIN OR EYES. DO NOT DELAY.
PREPARATION
■Check that all hardware is properly installed.
Always tighten to torque chart specications
unless instructed otherwise in this manual.
■Always wear relatively tight and belted clothing
to avoid entanglement in moving parts. Wear
sturdy, rough-soled work shoes and protec-
tive equipment for eyes, hair, hands, hearing,
and head; and respirator or lter mask where
appropriate.
■Make sure attachment is properly secured, ad-
justed, and in good operating condition.
■Power unit must be equipped with ROPS or
ROPS cab and seat belt. Keep seat belt secure-
ly fastened. Falling off power unit can result in
death from being run over or crushed. Keep
foldable ROPS systems in “locked up” position
at all times.
■Make sure all safety decals are installed.
Replace if damaged. (See Safety Decals section
for location.)
■Make sure shields and guards are proper-
ly installed and in good condition. Replace if
damaged.
OPERATION
■Do not allow bystanders within 25 feet of the
area when operating, attaching, removing, as-
sembling, maintaining, or servicing equipment.
■Consult local utilities before working. Know
location of all underground cables, pipelines,
overhead wires, and other hazards in working
area and avoid contact.
■Do not put stump grinder into service unless
all shields and guards are in place and in good
condition. Replace if damaged.
■Keep bystanders at least 100 feet away from
equipment.
■Do not operate or transport equipment while
under the inuence of alcohol or drugs.
■ Operate only in daylight or good articial light.
■Avoid contact with electrical wires.
■Keep hands, feet, hair, and clothing away from

all moving parts.
■Always comply with all state and local lighting
and marking requirements.
■Never allow riders on power unit or attachment.
Safety is a primary concern in the design and man-
ufacture of our products. Unfortunately, our efforts
to provide safe equipment can be wiped out by an
operator’s single careless act.
In addition to the design and conguration of
equipment, hazard control and accident preven-
tion are dependent upon the awareness, concern,
judgement, and proper training of personnel in-
volved in the operation, transport, maintenance
and storage of equipment.
It has been said “The best safety device is an in-
formed, careful operator.” We ask you to be that
kind of operator.

anti-sway links to prevent stump grinder from
moving during operation.
■Make sure lift cylinder is completely retracted
before backing up to a stump. If cylinder is ex-
tended, debris guard may get pushed into the
cutting wheel and be destroyed.
1. Power for operating the stump grinder is supplied by
the tractor PTO. Know how to stop the tractor and
stump grinder quickly in an emergency.
2. Position stump grinder above stump to be removed
with the main frame crossbrace on the ground and
the cutting wheel in the raised position.
3. Engage PTO at low engine rpm to minimize stress
on the drive system and gearbox. With PTO en-
gaged, increase PTO speed to 540 rpm and
maintain throughout grinding operation.
4. Activate lift cylinder to lower the cutting wheel onto
the stump to desired depth.
NOTE: The amount of material removed may vary
depending on tractor size and hardness of wood.
5. Start cutting wheel on left edge of stump and slow-
ly activate swing cylinder to begin grinding. Cutting
wheel can pivot 44-degrees from side to side.
6. With pass across stump completed, lower cutting
wheel on the right edge of the stump and slowly
activate the swing cylinder to the left. The cutting
wheel has cutting teeth on both sides to perform the
cut.
NOTE: If stump is too large to remove in one pass, re-
position tractor and start operating procedures over.
■Lift cylinder must be completely retracted to
avoid driveline damage before raising 3-point
lift arms.
■Always raise cutting head to avoid pushing
the debris guard into the cutting wheel during
repositioning.
When nished grinding stump, disengage PTO, raise
lift cylinder, and raise stump grinder main frame off the
ground with the 3-point lower lift arms.
STUMP GRINDER STORAGE
1. Lower stump grinder with 3-point lower lift arms until
main frame crossbrace is on the ground. Activate lift
cylinder and lower cutting head to the ground.
2. Disconnect driveline from tractor and place in stor-
age bracket.

LUBRICATION INFORMATION
1. Do not let excess grease collect on or around parts,
particularly when operating in sandy areas.
2. Use a lithium grease of #2 consistency with a MOLY
(molybdenum disulde) additive for all locations un-
less otherwise noted.
NOTE: Be sure to clean ttings thoroughly before
attaching grease gun. One good pump of most
guns is sufcient when the lubrication schedule is
followed.
3. Grease stump grinder pivot points every 8 hours.
Gearbox Lubrication
For gearbox, use a high quality gear oil with a viscosity
index of 80W or 90W and an API service rating of GL–
4 or GL–5.
Fill gearbox until the oil runs out the side plug on gear-
box. Check gearbox daily for evidence of leakage, and
contact your dealer if leakage occurs.
Driveline Lubrication
1. Lubricate the driveline slip joint every eight oper-
ating hours. Failure to maintain proper lubrication
could result in damage to the U-joints, gearbox, and
driveline. See Figure 5.
2. Lower stump grinder to ground, disconnect driveline
from tractor PTO shaft, and slide halves apart but
do not disconnect from each other.
3. Apply a bead of grease completely around male half
where it meets female half. Slide drive halves over
each other several times to distribute grease.

ken, or excessively worn. Excessively worn cutting
edges greatly decrease cutting efciency.
■Never operate the stump grinder with missing
teeth.
1. Use a 15/16 socket wrench and remove the 5/8"
jam nuts as shown in Figure 6.
2. Remove hex nut from tooth and remove tooth.
3. When installing new teeth, torque the 5/8" jam nuts
to 170 lbs-ft (230 N-m).
Figure 6. Tooth Installed
SLIP CLUTCH ADJUSTMENT
The slip clutch is designed to slip so that the gear-
box and driveline are protected if the cutter strikes an
obstruction.
A new slip clutch or one that has been in storage over
the winter may seize. Before operating the grind-
er, make sure it will slip by performing the following
operation:
1. Turn off tractor engine and remove key.
2. Loosen eight 10 mm cap screws (6) to remove all
tension from pressure plate (5). Springs should ro-
tate freely.
3. Place a mark on edge of lining rings (3).
4. Hold anged hub (4) solid and rotate driveline to
make sure clutch slips. Check marks on edge of lin-
ing rings to see if they have moved.
5. If clutch does not slip freely, disassemble and clean
surface of anged hub (4), ange yoke (1), and
pressure plate (5).
6. Reassemble clutch.
7. Tighten springs (7) until they are compressed to the
1.26 inches shown in Figure 7.
8. If a clutch continues to slip when the springs are
compressed to the 1.26 inch dimension, check
lining rings (3) for excessive wear. Rings are 1/8"
when new. Replace rings after 1/32" wear to ensure
proper operation.

CYLINDER SERVICE
The cylinders are designed to be reliable and easy
to service. If a cylinder should malfunction during the
warranty period, return the complete cylinder assem-
bly, without disassembling, to your authorized service
department or contact your authorized service depart-
ment for instructions. Unauthorized disassembly of a
cylinder in the warranty period will VOID WARRANTY.

Figure 18. 1021509 Hydraulic Cylinder
Lightly coat rod threads with hydraulic oil and slide
O-ring (3A) over threads and into groove. Completely
clean threads of hydraulic oil, apply Locquic Primer
7649 and Loctite 242 to the rod threads, and thread
piston (6) onto rod (1) with the two holes in the piston
orientated away from the rod. Torque the piston (6) to
100 lbs-ft.
Compress wear rings and piston seals and carefully in-
sert piston and rod assembly into barrel. Use care to
prevent damage while installing. Carefully screw rod
guide (5) into barrel (8) using a spanner wrench, or
carefully use a punch and hammer.
SWING CYLINDER REPAIR
Repair to cylinders is limited to replacing seals, wear
rings, and O-rings. Replacing rod, barrel, or pistons is
not cost effective. Purchasing a complete cylinder is
more economical.
Disassembly
Remove retaining ring (G) from barrel (2). Slide rod
assembly (3) out of barrel. Inspect inside of cylinder
barrel and rod surface for any scratches or scouring.
Small scratches can be removed with ne crocus cloth.
If scratches cannot be repaired, replace entire cylinder.
Clamp tube end of rod assembly in vise. Use a small
torch to heat nut (4) and break down the thread-locking
compound. Remove nut. Remove piston (5) and rod
guide (1) from rod assembly. Clean threads on rod as-
sembly and nut. Discard all seals.

Assembly
Lubricate new seals with clean oil. Install O-ring (D)
and back up ring (E) in the outer groove of guide (1).
Note the position of the backup ring. Install rod seal
(F) in inner groove of rod guide. Note that the lips of
the seal should be toward the piston side of the guide.
Install wiper (H) with lip pointed outward from guide.
Slide rod guide onto rod assembly.
Install O-ring (B) and seal (A) on piston (5). Apply oil to
threads on rod assembly. Slide O-ring (C) over threads.
Install piston. Apply permanent type thread-locking
compound to rod threads and install nut. Torque nut to
125-135 lbs-ft.
