The purpose of this manual is to assist in setting up,
operating and maintaining your backhoe. 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 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 in-line
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.

Figure 1. Backhoe Directions

Throughout this manual, references are made to right,
left, forward and rearward directions. These are deter­mined from the backhoe operator seat position facing
rearward as shown in Figure 1.

■ Some illustrations in this manual show the

backhoe with safety shields removed to provide a
better view. The backhoe should never be operated
with any safety shielding removed.

Terms for backhoe components have some variations
throughout the industry. We use SAE designations as
shown in Figure 2.

INSTALLATION

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.

SAFETY RULES

ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!

 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

BH6500/7500/9000_SR (Rev. 6/23/2006)

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.

 Never allow children or untrained persons to
operate equipment.

PREPARATION

 Check that all hardware is properly installed.

CAUTION

The operator is responsible for the safe operation of
the backhoe. The operator must be properly trained.
Operators should be familiar with the backhoe, the
tractor, and all safety practices before starting opera­tion. Read the safety rules and safety decals on pages
7 to 11.

 Never put backhoe into service unless backhoe
manufacturer's 3-point hitch Saf-T-Lok

START AND STOP OPERATION

 Operate tractor PTO at 540 RPM. Do not exceed.

An optional tractor-driven PTO pump supplies hydraulic
pressure for backhoe operation. Instructions for engag­ing and disengaging the PTO are in your tractor man­ual. Learn how to disengage PTO quickly should an
emergency occur.

Never exceed 540 rpm. Operating the pump in excess
of 540 rpm will cause overheating and equipment dam­age.

GENERAL OPERATION

 Place and keep 3-point lift quadrant lever in low­ered position at all times.

 If tractor is equipped with draft sensing control,
set control to “HEAVY” (minimum sensitivity) posi­tion.

 Do not use backhoe for craning; it is primarily
designed for digging. Mechanical failures such as
hose rupture will cause a load to drop suddenly.

 Never allow children or untrained persons to
operate equipment.

 When operating controls, always sit in backhoe
seat.

 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.

 Consult local utilities before working. Know
location of all underground cables, pipelines, over­head wires, and other hazards in working area and
avoid contact.

 A minimum 25% 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.

12 Operation

Figure 1. Backhoe Swing Area.

MAN0450 (10/28/2005)

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 1, 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

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.

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 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.

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.

CONTROL HANDLE OPERATION

Refer to Figure 2.

Assume your position in the operator's seat.

When engaging optional PTO-mounted pump, engine
rpm should always be low. Once engaged, engine rpm
may be increased to desirable operation speed (not to
exceed 540 rpm).

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.

Operate the control levers, swinging the boom several
times to practice control. Do not operate the swing
more than 45 degrees each way the first few times.
Gradually increase arc.

MAN0450 (10/28/2005)

Figure 2. Operator’s Controls (Typical View)

Operation 13

After becoming familiar with the backhoe operation,

WARNING

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.

BH80-X SWING SPEED CONTROL

The swing speed control valve is located on the back
side of the console on BH80-X backhoes only. This
controls the speed of the swing cylinders and allows for
easier operation in tight areas. Turn knob to the right to
Decrease swing speed and to the left to increase swing
speed.

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.

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.

START EXCAVATION

 Consult local utilities before working. Know
location of all underground cables, pipelines, over­head wires, and other hazards in working area and
avoid contact.

Figure 3. Starting Position

To start the excavation, position backhoe as shown in
Figure 3 for maximum breakout force.

Actuate the dipper cylinder to start digging. Approxi­mately halfway through digging cycle, start bucket curl
while continuing crowding dipper in. Should bucket
stall, raise boom slightly.

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.

Figure 4. 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

Refer to Figure 5.

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.

14 Operation

MAN0450 (10/28/2005)

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.

Figure 9. Tractors with Open-Center Valves

MECHANICAL THUMB (OPTIONAL)

The mechanical thumb is used for grabbing objects
and securing them between the thumb and the bucket.

Become familiar with the geometry and extra weight
the thumb adds to the backhoe before operating. Large
heavy objects such as rocks and logs can increase
momentum when pivoting backhoe to the side. DO
NOT make sudden stops and starts. Be extremely
careful lifting and moving long items such as poles or
tree limbs which may extend beyond the normal back­hoe operating area.

Improper usage can also damage the thumb or back­hoe. DO NOT use the thumb to rake material, push or
pull material, use the side of the thumb to move mate­rial, use as a lifting devise with chain or rope, or as a
pry bar to dislodge objects.

Place thumb in operating position by selecting an
appropriate pin location on the telescoping tube.
Rotate the bucket to hold material against the thumb.

When normal backhoe operation is required, place
thumb in storage position. Remove pin, rotate thumb
up against dipper, and insert pin to lock thumb into
position.

PRE-OPERATION CHECK LIST

RELIEF VALVE

BH70-X

This valve is pre-set at the factory to prevent system
pressure from exceeding 2030 psi. Do not attempt to
reset the valve for open-center hydraulic systems. If
valve is malfunctioning, replace it with an authorized
factory replacement part or have service done by a
qualified dealer.

 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.

HYDRAULIC HOSES AND FITTINGS

IMPORTANT

■ Fittings with O-rings and flange do not require

additional sealant; replace damaged O-rings.

Hydraulic hoses are severely worked on a backhoe.
Examine them daily and replace if necessary. Hose
routing is very important. Make certain hoses can move
freely, without kinking, and cannot be damaged or cut
by backhoe action.

When tightening hoses and fittings, always use two
wrenches: one to hold hose and one to tighten fitting.
This will prevent hose from twisting and kinking.

WARNING

The information in this section is written for dealer ser­vice personnel. The repair described here requires
special skills and tools. If your shop is not properly
equipped or your mechanics are not properly trained in
this type of repair, it may be more time and cost effec­tive to replace complete assemblies.

 Keep hands and body away from pressurized
lines. Use paper or cardboard, not hands or other

 Adjustment of system relief pressure must be
done by a qualified, experienced dealership. Incor­rect adjustment can result in system failures and
serious personal injury.

No individual parts are available for relief valve.
Replace entire assembly if required.

Pressure Setting Adjustment

NOTE: Before changing the pressure setting on the

valve, determine tractor hydraulic system pressure.
Many tractors do not create 2000 psi. If your tractor
does not create 2000 psi, changing the relief valve set­ting will not improve the backhoe performance.

To adjust relief valve setting, place a 3000 psi pressure
gauge in the line attached to the valve inlet (IN) port.
Remove cap from top of main relief (1, Figure 13). Turn
adjusting screw clockwise to increase pressure and
counter clockwise to decrease pressure. Start tractor
and set throttle for full engine speed. Move right stabi­lizer control lever to raise stabilizer to transport position
and hold the lever so full pressure builds. Adjust screw
to attain 2000 psi. Shut off tractor and replace cap.

Port Relief Valves

Pressure settings on port relief valves are preset at the
factory. Although they are adjustable, they must not be
reset in the field using backhoe hydraulic system. An
incorrect setting could cause hydraulic pump to fail or
backhoe cylinder rods to buckle.

 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.

ADJUST CONTROL VALVE LINKAGE

WARNING

Reconnect control linkage to valve.

Relief valve adjustment requires a test bench and
accurate gauges.

Control handles should be positioned as shown.

When completing a maintenance function on the valve,
perform a functional test by placing control handles in
their various positions and make certain the correct
operation occurs corresponding to the decals on the
operator's console. Pay specific attention to the float
position of the boom. Do not operate backhoe if func­tions differ from the decal.

If the functions differ from the decal, check to make
sure control linkage is correctly installed and check
plumbing schematics to make sure hoses are correctly
connected.

Adjusting System Relief Valve Pressure

 Adjustment of system relief pressure must be
done by a qualified, experienced dealership. Incor­rect adjustment can result in system failures and
serious personal injury.

NOTE: Before changing the pressure setting on the

valve, determine tractor hydraulic system pressure.
Many tractors do not create 2000 psi. If your tractor
does not create 2000 psi, changing the relief valve set­ting will not improve the backhoe performance.

Place a pressure gauge in the pump pressure line at
the relief valve. When installing pressure gauge, be
sure to use steel fittings that will withstand working
pressure up to 5000 psi.

Remove cap nut (6a). Adjusting screw (6c) has a hex
socket - rotate screw clockwise to increase pressure
and counter-clockwise to decrease pressure.

Start tractor and engage PTO (for pump kits) set throt­tle at PTO speed. Set system relief valve pressure at
2470 psi. When pressure is adjusted, shut tractor PTO
and tractor off. Replace cap nut (6a) on system valve.

HYDRAULIC VALVE REPAIR

Refer to Figure 15.

Valve repair should be accomplished in a clean work
place. Individual components for many of the assem­blies are not available as repair parts. This will simplify
repair and allow you to replace complete assemblies.

Pressure Settings on Port Relief Valves

Pressure settings on port relief valves are pre-set at
the factory. Although they are adjustable, they must not
be reset in the field using backhoe hydraulic system.
The backhoe pump will separate or crack if system
pressure exceeds the maximum.

Replacing Port Relief Valves

It is not necessary to remove valve from console to
replace port relief valve cartridges. Remove console
cover and replace them. Be sure you install valve car­tridges set at the correct pressure. Valves are similar
and can be easily mixed up.

Segment Replacement

Relieve system pressure and remove valve from back­hoe. Remove tie rods and separate the valve sections.

Replace defective sections as necessary. Make sure
you install two spacers between each section of each
tie rod. Note the location of O-rings (9 & 10). They must
be placed in the location between valve sections as
shown in Figure 15.

When assembling valve sections, use care when torqu­ing nuts on tie rods. This must be done in steps - that is
to say, gradually increasing the tightening torque up to

MAN0450 (10/28/2005)

Dealer Service 25

13 lbs-ft. in an alternating sequence. Non-uniform or
excessive tightening can cause binding of spools. Fail-

ure to attain the proper torque can result in leaks.

General Hydraulic Repair Information

The only repair parts available for these cylinders are
seal kits. If damage occurs to one of the cylinder com­ponents, replace the cylinder.

Inspect inside of cylinder barrel and rod surface for any
scratches or scouring. Small scratches can be
removed with fine crocus cloth. If scratches cannot be
repaired, replace entire cylinder.

Assemble

NOTE: Before ordering seal kits, check stamping on

barrel. Part numbers ending with either "E" or "J"
require specific seal kits. See parts page 45 for correct
seal kit number.

A clean working area is essential for any hydraulic
repair.

All parts must be carefully cleaned before reassembly.
We recommend that when repairing hydraulic compo­nents, you always replace existing seals with new
ones. Clean all components in solvent and blow dry
with low pressure air.

GENERAL ASSEMBLY INSTRUCTIONS

Backhoe assembly is the responsibility of the WOODS
dealer. The backhoe should be delivered to the owner
completely assembled, lubricated and adjusted for nor­mal operating conditions.

Set backhoe up as received from the factory with these
instructions and illustrations.

The backhoe must only be mounted with a tractor 3­point hitch using WOODS 3-Point Mount kit or a
WOODS sub-frame kit. See WOODS 3-Point Mount
manual for mount installation instructions.

 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.

When mounting this backhoe on a tractor using a sub­frame mount, special assembly instructions (which are
contained in another manual furnished with the sub­frame) apply to some of the assembly procedures.

The backhoe is shipped partially assembled. Assembly
will be easier if components are aligned and loosely
assembled before tightening hardware.

NOTE: References to right, left, forward and rearward
directions are determined from the backhoe operator
seat position facing rearward.

 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.

STABILIZER INSTALLATION

Remove stabilizer arms from pallet.

Remove pivot pins (27) from their shipping position.
Attach stabilizer arm (20) to main frame (3) with pivot
pin (27) and secure with snap ring (67).

Attach stabilizer cylinder (5) to stabilizer arm with pivot
pin (25) and secure with two cotter pins (38).

Figure 18. Backhoe Directions

 Keep all persons away from operator control
area while performing adjustments, service, or
maintenance.

 Only mount this backhoe on Category 1 tractors
with 800 lb. lift capacity at 24" behind 3-point lift
arm hitch balls.

 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.

TACT A PHYSICIAN IMMEDIATELY IF FLUID
ENTERS SKIN OR EYES. DO NOT DELAY.



Make sure shields and guards are properly

installed and in good condition. Replace if damaged.

Power to the backhoe can be supplied directly from the
tractor hydraulic system. A hydraulic requirement of 5­7 gallons per minute and 2000 PSI (BH70-X) or 2400
psi (BH80-X) is necessary to operate the backhoe effi­ciently. 3/8" diameter hoses (SAE 100 R1 with 2500
PSI working pressure) should be used to connect the
hydraulic source to the backhoe valve. These hoses
must be long enough to allow ease of removal or
attachment of backhoe. Hoses must include external
shielding to prevent oil from spraying on operator if
hose fails.

Open-Center

Refer to Figure 21.

Remove the console cover from the backhoe to gain
access to control valve (1). Connect 3/8" hoses (2 & 3)
to the backhoe inlet and outlet ports. Install couplers (4)
compatible to the tractor on opposite end of the 3/8"
hoses. Determine the direction of flow and connect
tractor pressure hose (6) to the inlet side of the control
valve (under left foot rest).

Note: The backhoe will not function if oil is routed back­wards through the valve. Connect the tractor return
hose (5) to the control valve outlet port. Tighten all fit-

Assembly 31

tings securely. Start engine and run at low rpm. Acti­vate hydraulic circuit and check for leaks.

TION

On tractors with non-standard drawbars, it may be nec­essary to modify pump bracket by enlarging the open­ing. Bracket may also be inverted and retained on the
top link bar. Whatever mounting is used, it is important
that pump be restrained from rotating.

 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.

 Make sure spring-activated locking pin or collar
slides freely and is seated firmly in tractor PTO
spline groove.

Attach pump mounting plate (18) to pump with bolts
(19) and nuts (20), Figure 22.

Check all hydraulic fittings and lines to be sure they are
tight and free of kinks and twists.

SEAT INSTALLATION AND ADJUSTMENT

The seat may be adjusted fore, aft, up and down for
operator comfort. It is necessary to use the two adjust­ments together. Moving the seat down also moves it
forward, moving it up also moves it rearward. The fore
and aft adjustment may be used with the up and down
adjustment to obtain desired position. Never operate
the backhoe unless manufacturer's 3-point hitch Saf-T­Lok Limiter or sub-frame has been installed, adjusted
and operator's area (shown in decal 1011992, see
decal page 11) is free from obstructions.
