GENERAL INFORMATION
The purpose of this manual is to assist you in operating
and maintaining your stump grinder. Read it carefully. It
furnishes information and instructions that will help you
achieve years of dependable performance. These
instructions have been compiled from extensive field
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.
The illustrations and data used in this manual were current at the time of printing but, due to possible 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 notification.
Throughout this manual, references are made to right
and left directions. These are determined from the
operator’s position in the tractor seat.

AFETY RULE
S
ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
Safety is a primary concern in the design and
manufacture 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 configuration of
equipment, hazard control and accident prevention are dependent upon the awareness, concern, judgement, and proper training of
personnel involved in the operation, transport,
maintenance, and storage of equipment.
It has been said, “The best safety device is an
informed, careful operator.” We ask you to be
that kind of operator.
TRAINING
Safety instructions are important! Read all
attachment 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.
PREPARATION
Check that all hardware is properly installed.
Always tighten to torque chart specifications
unless instructed otherwise in this manual.
Always wear relatively tight and belted clothing
to avoid getting caught in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head;
and respirator or filter mask where appropriate.
Make sure attachment is properly secured,
adjusted, and in good operating condition.
Power unit must be equipped with ROPS or
ROPS cab and seat belt. Keep seat belt securely
fastened. Falling off power unit can result in death
from being run over or crushed. Keep foldable
ROPS system 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 properly
installed and in good condition. Replace if damaged.
OPERATION
Know your controls and how to stop engine and
attachment quickly in an emergency.
Operators must be instructed in and be capable
of the safe operation of the equipment, its attachments, and all controls. Do not allow anyone 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 safety goggles.
Hydraulic fluid under pressure can easily penetrate
skin and will cause serious injury or death.
Make sure that all operating and service personnel know that if hydraulic fluid penetrates skin, it
must be surgically removed as soon as possible 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.
SG100 Safety Rules (Rev. 6/16/2006)
Do not allow bystanders in the area when operating, attaching, removing, assembling, 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 away from equipment.
Do not operate or transport equipment while
under the influence of alcohol or drugs.
Operate only in daylight or good artificial light.

SAFETY RULES
ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
(Safety Rules continued from previous page)
Avoid contact with electrical wires.
Keep hands, feet, hair, and clothing away from
equipment while engine is running. Stay clear of all
moving parts.
Always comply with all state and local lighting
and marking requirements.
Never allow riders on power unit or attachment.
Power unit must be equipped with ROPS or
ROPS cab and seat belt. Keep seat belt securely
fastened. Falling off power unit can result in death
from being run over or crushed. Keep foldable
ROPS system in “locked up” position at all times.
Always sit in power unit seat when operating
controls or starting engine. Securely fasten seat
belt, place transmission in neutral, engage brake,
and ensure all other controls are disengaged
before starting power unit engine.
Shift tractor transmission into park or neutral
and set brakes before engaging PTO and grinding.
Do not operate PTO during transport.
Do not operate auxiliary hydraulics during
transport.
Look down and to the rear and make sure area
is clear before operating in reverse.
Use extreme care when working close to fences,
ditches, other obstructions, or on hillsides.
Do not operate or transport on steep slopes.
Do not stop, start, or change directions sud-
denly on slopes.
Use extreme care and reduce ground speed on
slopes and rough terrain.
Before performing any service or maintenance,
lower equipment to ground or block securely, turn
off engine, remove key, and disconnect driveline
from tractor PTO.
NEVER GO UNDERNEATH EQUIPMENT. Never
place any part of the body underneath equipment
or between moveable parts even when the engine
has been turned off. Hydraulic system leak-down,
hydraulic system failures, mechanical failures, or
movement of control levers can cause equipment
to drop or rotate unexpectedly and cause severe
injury or death.
• Service work does not require going underneath.
• Read Operator's Manual for service instruc-
tions or have service performed by a qualified
dealer.
TRANSPORTATION
A minimum 20% of tractor and equipment
weight must be on the tractor front wheels when
attachments are in transport position. Without this
weight, tractor could tip over, causing personal
injury or death. The weight may be attained with a
loader, front wheel weights, ballast in tires or front
tractor weights. Weigh the tractor and equipment.
Do not estimate.
Reduce transport speed to avoid bouncing and
brief loss of steering control.
Always comply with all state and local lighting
and marking requirements.
Never allow riders on power unit or attachment.
Turn off power to unit before transporting.
Do not operate or transport on steep slopes.
Do not operate or transport equipment while
under the influence of alcohol or drugs.
MAINTENANCE
Service and maintenance work not covered in
OWNER SERVICE must be done by a qualified
dealership. Special skills, tools, and safety procedures may be required. Failure to follow these
instructions can result in serious injury or death.
Before performing any service or maintenance,
lower equipment to ground or block securely, turn
off engine, remove key, and disconnect driveline
from tractor PTO.
Do not modify or alter or permit anyone else to
modify or alter the equipment or any of its components in any way.
Always wear relatively tight and belted clothing
to avoid getting caught in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head;
and respirator or filter mask where appropriate.
Do not allow bystanders in the area when operating, attaching, removing, assembling, or servicing equipment.
Make sure attachment is properly secured,
adjusted, and in good operating condition.
Never perform service or maintenance with
engine running.

BE CAREFUL!
Use a clean, damp cloth to clean safety decals.
Avoid spraying too close to decals when using a pressure washer; high-pressure water can enter
through very small scratches or under edges of decals causing them to peel or come off.
Replacement safety decals can be ordered free from your Woods 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.
