INSTALLATION
Hydraulics must be connected as instructed in
this manual. Do not substitute parts, modify, or
connect in any other way.
TRAINING
Safety instructions are important! Read all
attachment and power unit manuals; follow all
safety rules and safety decal information. (Replace-
ment 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 capable
of the safe operation of the equipment, its attach-
ments, and all controls. Do not allow anyone to
operate this equipment without proper instruc-
tions.
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 person-
nel 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 gan-
grene, serious injury, or death will result. CON-
TACT A PHYSICIAN IMMEDIATELY IF FLUID
ENTERS SKIN OR EYES. DO NOT DELAY.
Never allow children or untrained persons to
operate equipment.
PREPARATION
Check that all hardware is properly installed.
Always tighten to torque chart specifications
unless instructed otherwise in this manual.
Air in hydraulic systems can cause erratic oper-
ation and allows loads or equipment components
to drop unexpectedly. When connecting equipment
or hoses or performing any hydraulic maintenance,
purge any air in hydraulic system by operating all
hydraulic functions several times. Do this before
putting into service or allowing anyone to
approach the equipment.
Make sure all hydraulic hoses, fittings, and
valves are in good condition and not leaking before
starting power unit or using equipment. Check and
route hoses carefully to prevent damage. Hoses
must not be twisted, bent sharply, kinked, frayed,
pinched, or come into contact with any moving
parts. Operate moveable components through full
operational range to check clearances. Replace
any damaged hoses immediately.
After connecting hoses, check that all control
lever positions function as instructed in the Opera-
tor's Manual. Do not put into service until control
lever and equipment movements are correct.
Your dealer can supply original equipment
hydraulic accessories and repair parts. Substitute
parts may not meet original equipment specifica-
tions and may be dangerous.
Set tractor hydraulic relief valve at 2500 psi (170
bars) (17,000 kPa) to prevent injury and equipment
damage due to hydraulic system failure.
Do not connect a low-pressure hydraulic hose
into a high-pressure system—it will burst the hose.
Do not use a high-pressure hose in place of a low-
pressure hose—it is possible to rupture the valve.
Always wear relatively tight and belted clothing
to avoid entanglement in moving parts. Wear
sturdy, rough-soled work shoes and protective
equipment for eyes, hair, hands, hearing, and head.
Make sure attachment is properly secured,
adjusted, and in good operating condition.
(Safety Rules continued on next page)
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 preven-
tion 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.

ASSEMBLY INSTRUCTIONS
DEALER SET-UP INSTRUCTIONS
Assembly of this Rear Blade is the responsibility of the
WOODS dealer. The 50 Series Rear Blades are
shipped fully assembled. The 60 Series Rear Blades
are shipped partially assembled and will need the
mechanical or hydraulic adjustment kits assembled.
All Rear Blades should be delivered to the owner com-
pletely assembled, lubricated, and adjusted for normal
conditions.
Complete the Dealer Checklist on Page 25 when set-
up is complete and the Rear Blade is delivered to the
Owner.
Before dismounting power unit or performing
any service or maintenance, follow these steps:
disengage power to equipment, lower the 3-point
hitch and all raised components to the ground,
operate valve levers to release any hydraulic pres-
sure, set parking brake, stop engine, remove key,
and unfasten seat belt.
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
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 person-
nel 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 gan-
grene, serious injury, or death will result.
CONTACT A PHYSICIAN IMMEDIATELY IF FLUID
ENTERS SKIN OR EYES. DO NOT DELAY.
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 under-
neath implement.
• Read Operator's Manual for service instruc-
tions or have service performed by a qualified
dealer.
Always wear relatively tight and belted clothing
to avoid entanglement 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.
Tighten all bolts, nuts, and screws to torque
chart specifications. Check that all cotter pins are
installed securely to ensure equipment is in a safe
condition before putting unit into service.
