SAFETY RULES
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.
INSTALLATION
Hydraulics must be connected as instructed in
this manual. Do not substitute parts, modify, or
connect in any other way.
After connecting hoses, check that all control
lever positions function as instructed in the Operator's Manual. Do not put into service until control
lever and equipment movements are correct.
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.
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 gan-
grene, serious injury, or death will result. CONTACT 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 operation 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.
After connecting hoses, check that all control
lever positions function as instructed in the Operator's Manual. Do not put into service until control
lever and equipment movements are correct.
Protective hose sleeves must cover all hydraulic hoses within 20 inches of the operator and be
secured onto metal hose fittings. Replace hoses or
sleeves if damaged or if protective sleeve cannot
be properly positioned or secured.
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.
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 spring-activated locking pin or collar
slides freely and is seated firmly in tractor PTO
spline groove.
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.

When operating controls, always sit in backhoe
seat.
Mechanical failures such as a hose rupture will cause a
load to drop. Lifting a heavy load with the dipper, then
operating the boom, could cause boom to drop. In
either case, if anyone is in the operating area (maximum reach of bucket) as shown in Figure 3, serious
injury or death could occur.
Do not dig with backhoe unless stabilizers are down
and on a firm surface. Stay clear of steep areas or
excavation banks that are soft or could give way.

Figure 3. Backhoe Swing Area.
POSITION THE MACHINE
Before operating in an unfamiliar area, walk around the
full length of the proposed site and check for hidden
holes, drop-off or obstacles that could cause an accident.
Lower stabilizers until they carry the weight of the backhoe. If tractor is equipped with a front loader, place the
bucket flat on the ground. Lower loader lift arms until
weight is removed from front tractor tires.
Level the machine using stabilizers and front loader
before starting to dig.
Stability is very important when operating backhoe in
the extreme swing positions as this causes weight
transfer.
When engaging optional PTO-mounted pump, engine
rpm should always be low. Once engaged, engine rpm
may be increased to desirable operation speed.
When becoming familiar with backhoe controls, start
with a lower rpm.
Before operating, perform a functional test by placing
control handles in their various positions and making
certain correct operation occurs, matching decals on
operator's console. Pay specific attention to the float
position of boom. Do not operate backhoe if functions
differ from decal; serious injury or death could occur.
It is not difficult to become a successful operator. Control lever operating decals (shown in Figure 4) are next
to the operating control levers. Study these decals;
they will assist you in becoming familiar with the controls.
Pushing handle 1 forward will lower left stabilizer; pulling back raises it.
Pushing handle 2 forward will lower right stabilizer;
pulling back raises it.
Pulling left control back (toward A) raises boom; pushing it forward (toward C) lowers it. Full forward (toward
C) is the float position.
Moving left handle left (toward B) swings boom left;
moving it right (toward D) swings boom right.
Pulling right control back (toward E) moves dipper
down and toward operator; pushing it forward (toward
G) moves it up and away from operator.
Moving right handle left (toward F) curls bucket toward
operator; moving it right (toward H) extends bucket out
away from operator.
CONTROL HANDLE OPERATION
Refer to Figure 4.
Assume your position in the operator's seat.
51861 (Rev. 6/16/2006)
Operate the control levers, swinging the boom several
times to practice control. Do not operate the swing
more than 45° each way the first few times. Gradually
increase arc.

After becoming familiar with the backhoe operation,
practice coordinated use of the controls in a safe open
area at reduced engine speed. Gradually increase
engine speed as the technique is mastered.
Operate backhoe gently and smoothly. Avoid swinging
boom into mainframe. Sudden stopping or jerking
could result in serious damage to tractor and backhoe.

Strive to develop a smooth digging cycle. Avoid abrupt
or jerky movements. This is accomplished by operating
two or more controls at the same time and not allowing
the cylinders to reach the limit of travel.
Should you become confused during operation, simply
let go of the controls. The valve control handles will
automatically return to neutral.
START EXCAVATION
WARNING
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 use down pressure on the boom when starting
to dig, as this will lift the machine and move it out of
alignment with the work.
FILL BUCKET
Control bucket attitude throughout digging cycle to
keep teeth parallel to bottom of excavation. This will
provide best penetration angle and minimize dragging
and scraping bucket through the ground.
Penetration depth is determined by soil condition and
type.
Only use dipper and bucket during the digging cycle.
As the dipper moves the bucket through the soil, curl
bucket to maintain proper bucket position.
At the end of the pass, or when bucket is full, curl
bucket completely, lift bucket from excavation and
swing boom to dump site.
DB3391
Figure 5. Starting Position
14 Operation
To obtain a cleaner trench and avoid material buildup
directly in front of backhoe, extend dipper and curl
bucket completely while starting to lift it out of the excavation. This will allow excess material to fall back into
the excavation.

SIDE SLOPE TRENCHING / EXCAVATING
WARNING
Be careful when swinging loaded bucket on hillside. Always dump spoil on uphill side of backhoe
to minimize rollover possibility.
Figure 6. Fill Bucket
DUMP AND RETURN CYCLE
Keep the swing-dump-return cycle as brief as possible.
Keep dipper moving outward and start boom swing as
soon as the bucket clears the excavation. Continue
extending dipper and, as you approach the spoil pile,
start to dump bucket.
When bucket is empty, dipper and bucket are in position to resume digging upon return to the excavation.
TRENCHING AND EXCAVATING
Trenching is the most basic backhoe digging operation.
Other operations are variations of this basic function.
To maintain a level trench bottom, set bucket at proper
approach angle and while crowding dipper-stick in,
continually move bucket curl lever to maintain correct
cutting angle. At the same time, place boom control in
the full forward (float) position and keep the bucket in
the same plane.
When handle is placed in the float position, pressure
on both sides of boom cylinder is released.
When operating on a side slope, the backhoe must be
positioned using one of these two methods as shown in
Figure 8 or Figure 9.
When operating on a side slope, always place the
trench spoil on the uphill side.
DB3388
Level the machine on side slope using the stabilizers.
Figure 8. Level with Stabilizers
When leveling with a cutout, cut a level pad for the
uphill side of the machine and place spoil on the downhill side as shown in Figure 9.
UPHILL
Spoil from
Level Pad
Digging near center of swing so material may be
dumped on either side will produce good results. Never
dig near stabilizers.
Continue the trench by moving machine along trench
centerline away from existing excavation. Move
machine approximately one-half the effective backhoe
reach. Moving too far will require excessive down pressure for digging and hand clean-up of trench bottom.

from being run over or crushed. Keep foldable
ROPS system in “locked up” position at all times.
WARNING
Never leave equipment unattended with engine
running or with bucket in raised position. Always
engage swing and boom transport locks, relieve
system pressure by operating controls, and
remove ignition key before leaving equipment.
Transport and Swing Lock Installation
IMPORTANT
■ Before operating backhoe, disengage transport
lock bar and store swing lock pin. Push transport
lock bar down fully to prevent damage.
Engage transport lock by fully retracting boom and dipper. Position transport latch plate (1), located on right
side of swing frame, over transport lock pin (2). Secure
with safety pin (4). See Figure 10.
Center boom from side to side and install swing lock
pin (6) through plates (8) and swing frame (7). Place
swing lock pin (6) in storage hole (9) when not in use.
DP1
Always raise stabilizers before transporting backhoe.
REMOVING AND STORING BACKHOE
DANGER
The only time the backhoe may be operated
from a position other than the operator seat is during backhoe attachment and removal. Operator
must:
• Read Mounting Kit Manual instructions on
attaching and removing backhoe and use
extreme care.
• Always stand between rear tire and backhoe
stabilizer arms or along side of tractor to avoid
being trapped should the boom swing control
be accidentally activated.
WARNING
Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.
Figure 10. Transport and Swing Lock Installed
3-Point Hitch Saf-T-Lok
Center the boom, install swing lock pin, then extend
boom and dipperstick. Rest bucket on the ground.
Lower stabilizers to take backhoe weight off of tractor.
Remove pin that attaches top link to tractor. Remove
lower 3-point arms from backhoe. Place blocks under
mainframe and raise stabilizers to lower backhoe mainframe onto blocks. Block backhoe as necessary to
make it stable.
Disconnect hydraulic pump from tractor and store off
ground. Slowly drive tractor away from backhoe.

CLEANING
After Each Use
● Remove large debris such as clumps of dirt, grass,
crop residue, etc. from machine.
16 Operation
51861 (Rev. 6/16/2006)
Inspect machine and replace worn or damaged
●
parts.
● Replace any safety decals that are missing or not
readable.
___ Check that there are no leaks in the hydraulic
system. Before operating, all hydraulic hoses
must be routed properly and not be twisted,
bent sharply, kinked, pulled tight or frayed.
Periodically or Before Extended Storage
● Clean large debris such as clumps of dirt, grass,
crop residue, etc. from machine.
● Remove the remainder using a low-pressure water
spray.
1. Be careful when spraying near scratched or torn
safety decals or near edges of decals as water
spray can peel decal off surface.
2. Be careful when spraying near chipped or
scratched paint as water spray can lift paint.
3. If a pressure washer is used, follow the advice
of the pressure washer manufacturer.
● Inspect machine and replace worn or damaged
parts.
● Sand down scratches and the edges of areas of
missing paint and coat with Woods spray paint of
matching color (purchase from your Woods
dealer).
● Replace any safety decals that are missing or not
readable (supplied free by your Woods dealer).
See Safety Decals section for location drawing.
___ During inspection, check that all nuts and bolts
are secure and clevis pins are properly cotter
pinned.
___ Be sure special heavy-duty top link, provided
with backhoe, is installed.
___ Make sure only original equipment high-
strength top link pin, provided with tractor, is
used to attach top link to tractor.
___ Use a 1" x 5" grade 5 bolt to mount top link to
backhoe.
___ Make sure tractor lower lift arm stabilizers
(blocks or chains) are positioned to prevent lift
arms and backhoe from swaying.
___ Place all backhoe controls in neutral position
before starting tractor engine.
___ Check hydraulic reservoir level.
___ Remove transport lock bar from the boom.
Push transport lock bar down fully to prevent
damage.
PRE-OPERATION CHECK LIST
(OWNER'S RESPONSIBILITY)
The operator should perform the following check list
before operating the backhoe.
___ Check that backhoe is properly and securely
attached to tractor.
___ Make sure all hydraulic connections are tight
and all hydraulic lines and hoses are in good
condition before engaging tractor PTO.
___ Place and keep 3-point lift quadrant lever in
lower position at all times.
___ Set draft sensing control to “heavy” (minimum
sensitivity) position. The minimum sensitivity
setting indicates to the tractor lift system that a
heavy load is being applied to the lift arms and
will minimize the potential for the lift arms to
raise. Raising lower lift arms would apply
greater loads to the Saf-T-Lok
braces, which is not desirable.

CAUTION
The information in this section is written for operators
who possess basic mechanical skills. If you need help,
your dealer has trained service technicians available.
For your protection, read and follow the safety information in this manual.
WARNING
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.
Before working on backhoe, extend boom and
dipperstick and place bucket on ground. Make sure
that all system pressure has been relieved by operating controls before maintenance, service, or disconnecting any hydraulic lines.
