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.

GENERAL OPERATION

WARNING

 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.

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.

DB2796A

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.

To start the excavation, position backhoe as shown in
Figure 5 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.

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.

DB3390

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.

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

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.

HYDRAULIC HOSES AND FITTINGS

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.

Always back lock nut off and screw fitting all the way in
for fitting that use O-rings for sealing. Then hold in
position and tighten lock nut.

IMPORTANT

■ Fittings with O-rings and flange do not require

additional sealant, replace damaged O-rings.

LUBRICATION

WARNING

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

Do not let excess grease collect on or around parts,
particularly when operating in sandy areas. Figure 13
shows lubrication points for the backhoe.

It is recommended that all fittings be lubricated daily or
every eight hours of operation. In very wet or dry condi­tions, lubricate every four hours of operation. Use an
SAE multi-purpose type grease for all locations shown
unless otherwise specified. Be sure to clean fitting thor­oughly before using grease gun. One good pump of
most guns is sufficient.

Position backhoe for easy lubrication by placing boom
and dipper at 90° to each other with bucket cutting
edge vertical and teeth resting on ground. Lower stabi­lizers to lubricate cylinders.

HYDRAULIC PUMP REPAIR

There are two suppliers approved for backhoe pumps.
They are Cessna and Sundstrand. Either type of pump
may be used to supply hydraulic pressure for the back­hoe, but the components of the pumps are not inter­changeable. You must determine which pump you are
repairing and obtain the correct repair parts.

Repair of the pump is limited to shaft seal replacement.

HYDRAULIC VALVE REPAIR

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
Shock/Dampening Valves

Pressure settings on shock/dampening valves are pre­set 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.

Relief valve adjustment requires a test bench and
accurate gauges.

Adjusting System Relief Valve Pressure

A WARNING

Replacing Shock/Dampening Valves

It is not necessary to remove console valve from con­sole to replace shock/dampening valve cartridges.
Remove console cover and replace them. Be sure you
install valve cartridges set at the correct pressure.
Valves are all pre-set at 2400 psi.

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

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

Remove cap nut (2a), see Figure 17. Adjusting screw
(2c) has a hex socket - rotate screw clockwise to
increase pressure and counter-clockwise to decrease
pressure.

Start tractor PTO and set system relief valve pressure
at 2100 psi. When pressure is adjusted, shut tractor
PTO and tractor off. Replace cap nut (2a) on system
valve.

4BB 2500 psi

Segment Replacement

Relieve system pressure and remove valve from back­hoe. Remove tie rods and separate the valve sections.
See Figure 17.

Replace defective sections as necessary. Make sure
you install two spacers between each section of each
tie rod. Note the location of O-rings (7 & 8). They must
be placed in the location between valve sections as
shown in Figure 17.

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
13 lbs-ft. in an alternating sequence. Non-uniform or
excessive tightening can cause binding of spools. Fail­ure to attain the proper torque can result in leaks.
Always use a torque wrench.

SWING CYLINDER CUSHION OIL FLOW
(FIGURE 18 & FIGURE 19)

Swing Cylinder Operational Theory

Our swing cylinders are designed to cushion and
soften swing action.

51861 (Rev. 6/16/2006)

Cross sections are shown in Figure 19 to give you a
view of the internal workings of the cylinder. Cushion­ing action is obtained by incorporating restrictors in the
cylinders. When the boom is swung, the fluid is allowed
to flow normally until the cylinder nears the end of the
stroke, then fluid is forced through the restrictors to
obtain the cushioning action.

ASSEMBLY

DEALER SET-UP INSTRUCTION

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

A CAUTION

 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.

A lifting bar is provided to maneuver the backhoe while
it is on the pallet. While backhoe is on a pallet, do not
lift from any other point. When backhoe is removed
from the pallet, remove lifting bar and discard.

Remove lag screw from swing frame, rotate boom and
dipper and install swing lock pin. Open parts bag and
box and lay out parts to make identification easy. Refer
to parts lists and exploded view drawing.

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

Recommended torque values for hardware are given
on page 55.

IMPORTANT

■ When finished with assembly, the dealer is to

complete the check lists on page 34.

ASSEMBLY PROCEDURE

A WARNING

 It is recommended that power unit 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 systems in “locked up” posi­tion at all times.

 Refer to “Mounting Guide” (available from your
dealer) for some tractors not originally equipped
with 1” diameter pins.

 A minimum 20% of tractor and equipment
weight must be on tractor front wheels with back­hoe 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. When attaining the minimum 20% weight
on the front wheels, you must not exceed the Roll
Over Protection Structure (ROPS) weight certifica­tion. Weigh the tractor and equipment. Do not esti­mate.

Read instructions before starting assembly. You will
save yourself assembly time.

Move Seat Support Assembly

Move seat support assembly from the four forward
holes on main frame to the four rearward holes for
operation. It will be easier to do this before mounting
backhoe on tractor.

Bucket & Dipperstick Installation

Align dipperstick cylinder (4) with dipperstick (2) and
install pivot pin (6) as shown in Figure 20. Line up hole
in pivot pin (6) with hole in pivot bushing and secure
with clevis pin (8) and cotter pin (9).

Align bucket (3) with pivot bushings of bucket arm (5)
and dipperstick (2) and install pivot pins (7). Line up
hole in pivot pin (6) with hole in pivot bushing and
secure with bolts (10) and lock nuts (11).

A WARNING

A 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.

28 Assembly

 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.

IMPORTANT

■ Clean all hydraulic fittings and secure to pre-

vent foreign material from entering hydraulic fit­tings. On fittings using O-rings, no additional
sealant such as pipe dope or teflon thread tape
should be used. We recommend the use of teflon
thread tape on pipe threads. Be care when applying
teflon tape to prevent it from entering the hydraulic
system.

Refer to Pump Mounting Bracket Installation in next
section and attach mounting bracket (3) to pump with
bolts (14) and lock nuts (13). Install tapered knobs (11)
to control handles as shown in Figure 21.

A lifting bar is provided to maneuver backhoe while it is
on the pallet. While backhoe is on a pallet, do not lift
from any other point. When backhoe is removed from
pallet, remove lifting bar and discard.

Remove lag screws from rear of backhoe and remove
backhoe from skid.

ATTACHING BACKHOE TO TRACTOR

Use either 540 or 1000 rpm PTO speed; never exceed
the rated pump rpm.

Only mount this backhoe on 50 hp or greater, Category
2 and 3 tractors with 2000 lb. minimum lift capacity and
with original equipment high-strength top link pin of at
least 1" diameter or approved top link brackets and
pins available form your WOODS dealer for some trac­tors not originally equipped with 1" diameter pins.

Service hydraulic reservoir by filling to full mark on dip­stick (approximately 9-1/2 to 10 U.S. gallons). When
backhoe is mounted and cylinders are filled, it will be
necessary to add fluid to reservoir. System capacity is
approximately 14 U.S. gallons.

IMPORTANT

■ Fill with clean oil. Do not mix oil types or

grades.

51861 (Rev. 6/16/2006)

Assembly 29

Contamination will shorten the life of hydraulic system
components. Change oil and filter after first 20 hours of
operation and then every 200 hours of operation.

ENGAGE PTO AND RUN AT IDLE FOR 5 MINUTES,
THEN CHECK OIL LEVEL. Add Fluid as necessary.

Position backhoe on level surface. Back tractor up as
near as possible to center of backhoe. Refer to Figure
23 and select a pump mounting that will work on you
specific tractor.

The bracket is designed to slip over the tractor draw­bar. The best installation is to place bracket down and
offset toward tractor. Offset may be reversed if interfer­ence occurs.

For tractors with a non-standard drawbar, it may be
necessary to enlarge pump bracket opening. Bracket
may be inverted and retained on top link bar. Make
sure pump is retained, whichever mounting configura­tion is used.

A WARNING

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

When pump is positioned, check that all hoses and fit­tings are positioned to avoid contact with other compo­nents.

Make sure backhoe controls are in centered neutral
position.

With backhoe hydraulic pump securely mounted and
tractor PTO and transmission in neutral, start tractor
engine idling. Engage PTO very carefully and allow
pump to start smoothly.

Figure 22. Pump Mounting Bracket Installation

Very little engine power is required to power the
hydraulic system in this mode. Should engine pull
down excessively, check plumbing hook-up for
reversed lines or a control lever stuck in an operating
position.

A 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.

 Never use 3-point mounted backhoe on tractor
equipped with cab or ROPS unless 3-point hitch

Saf-T-Lok
and adjusted. (Refer to Danger decal in Safety
Decal section.)

IMPORTANT

■ There may be more than one hole provided in

tractor top link attachment bracket; select the hole
that most evenly distributes the load between top
link bracket and its mounting bolts. See Figure 25.

Note that the maximum width between tractor top link
attachment plates must not exceed 2-1/2". This is to
prevent excessive bending loads on the top link pin.
Pin must be located in one of the positions shown.

32 Assembly

Figure 26. Saf-T-Lok Adjustment

With backhoe main frame vertical, refer to Figure 26,
align double and single top link bars and bolt together
using widest spread between bolts as possible. It may
be necessary to move main frame slightly off vertical
plane to align holes of top link.

Mount Saf-T-Lok diagonal bars to hole in top link bar as
close to tractor as possible; do not mount further than
6-3/4" away from tractor. Cut end of Saf-T-Lok diagonal
bars off to obtain mounting space if necessary. Place
two spacer washers between double top link bar when
mounting Saf-T-Lok diagonal bars.

Check distance from center of boom pivot pin and
ground to be sure there is from 11" to 14" clearance.
Check that console is nearly vertical with the ground.

51861 (Rev. 6/16/2006)

Make sure you meet minimum clearance distances
between ROPS or tractor cab. Required head clear­ance must take priority. Refer to Danger decal on
page 10. Make any adjustments required.

1. The bolt center distance attaching the diagonal
brace to the top link must not be more than 6-3/4"
from the tractor top link pin.

2. The bolts joining the two halves of the top link must
not be less than 2-1/2" apart.

3. The vertical distance between the attachment point
for the lower lift arms and the top link pin must not
be less that 12".

When clearance distances are verified and attachment
is complete, tighten hitch pin nuts to 600 ft-lbs. and
secure with cotter pin. Hitch pin nuts may be easier to
torque if the backhoe is removed from tractor.

Mount backhoe to tractor and tighten bolts attaching

Saf-T-Lok
top link bars together to 450 ft-lbs.

Safety Chain Installation

A DANGER

 Do not operate backhoe unless there is ade­quate operator clearance as shown on safety
decal. (Refer to Danger decal in Safety Decal sec­tion.)

Secure backhoe to tractor by inserting safety chain
through lower lift arm bracket (21) or wrapping around
tractor axle (22). The preferred attachment is through
bracket (21). Remove as much slack from chain as you
can.

A WARNING

 Make sure safety chain is properly connected
and secured to tractor.

Make sure tractor lower lift arm stabilizers (blocks or
chains) are positioned to prevent lift arms and backhoe
from swaying.

Secure hydraulic hoses between pump and backhoe
with nylon ties to prevent them from contacting sharp
objects.

Check hose positioning carefully through full range of
swing cylinder movement.

Fully extend and retract all cylinders several times to
purge all air from the hydraulic system. Retract all cylin­der and fill hydraulic reservoir to full mark on dipstick.
