IMPORTANT SAFETY PRECAUTIONS

This symbol is used to call attention to safe­ty precautions that should be followed by
the operator to avoid accidents. When you
see this symbol, carefully read the message
that follows and heed its advice. Failure to
comply with safety precautions could result
in death or serious bodily injury.

In addition to the design and configuration of equipment, hazard control and accident prevention are dependent upon
the awareness, concern, prudence and proper training of personnel in the operation, transport, maintenance and stor
age of equipment. Lack of attention to safety can result in accident, personal injury, reduction of efficiency and worst of
all—loss of life. Watch for safety hazards and correct deficiencies promptly. Use the following safety precautions as a
general guide to safe operations when using this machine. Additional safety precautions are used throughout this man
ual for specific operating and maintenance procedures. Read this manual and review the safety precautions often until
you know the limitations.

THE TRACTOR

1. Read the tractor operator’s manual to learn how to operate your tractor safely. Failure to do so could result in seri­ous injury or death and equipment damage.

2. Use ROPS (Roll-Over Protective Structure) and seat belt equipped tractors for operator use in all loader operations.

3. Add wheel ballast or rear weight for stability.

4. Move wheels to the tractor manufacturer’s widest recommended settings to increase stability.

5. For better stability, use tractor with wide front axle rather than tricycle front wheels.

6. Move and turn the tractor at low speeds.

7. Stop tractor engine, place transmission in park (or neutral), engage parking brake, lower loader arms to ground,
cycle all hydraulic controls to relieve pressure, allow machine moving parts to stop, remove ignition key to prevent
unauthorized person from starting engine before dismounting tractor or servicing, repairing, or making adjustments
to the equipment.

8. Wear personal protective equipment (PPE), such as, but not limited to, protection for eyes, ears, lungs, head, hands
and feet when operating, servicing, or repairing equipment. Avoid wearing loose clothing or jewelry that may catch
and entangle on equipment moving parts.

THE LOADER

1. Read the loader operator’s manual to learn how to operate your loader safely. Failure to do so could result in seri­ous injury or death and equipment damage.

2. Become familiar with all the machine’s controls and all the caution, warning and danger decals affixed to the
machine before attempting to start or operate.

3. Improper use of a loader can cause serious injury or death.

4. Do not lift or carry anybody on the loader or in the bucket or attachment.

5. Never allow anyone to get under the loader bucket or reach through the booms when the bucket is raised.

6. Do not walk or work under a raised loader bucket or attachment unless it is is securely blocked or held in position

7. Avoid overhead wires and obstacles when loader is raised. Contacting electrical lines can cause electrocution.

8. Make sure all parked loaders on stands are on a hard, level surface.

9. Use a piece of cardboard or wood rather than hands and wear eye protection when searching for hydraulic leaks.
Escaping hydraulic oil under pressure can penetrate skin. If oil is injected into skin, it must be surgically removed
within a few hours by a doctor or gangrene may result.

5

10. Before disconnecting hydraulic lines, relieve all hydraulic pressure.

11. Do not tamper with the relief valve setting. The relief valve is pre-set at the factory. Changing the setting can
cause overloading the loader and tractor and serious operator injury may result.

12. Always wear safety goggles when repairing or servicing machine.

13. When servicing or replacing pins in cylinder ends, buckets, etc., always use a brass drift and hammer. Failure to
do so could result in injury from flying fragments.

14. Replace damaged or illegible safety decals. See decal page for required decals.

15. Do not modify or alter or permit anyone else to modify or alter the loader, any of its components or any loader
function without first consulting your local dealer.

OPERATING THE LOADER

1. It is the loader owner’s responsibility to instruct and have a person read operator’s manual, safety decals and
become familiar with machine controls before allowing them to operate loader.

2. Do not allow children to operate the loader.

3. Before starting or operating the equipment, make a walk around inspection and check for loose or damaged
components. Correct any deficiency before starting.

4. Keep the area of operation clear of all persons, particularly small children. The operator should cease operation
whenever anyone comes within the operating area.

5. Operate the loader from the “Operator’s Seat Only.”

6. Exercise caution when operating the loader with a raised loaded bucket, fork, or large round hay bale handling
attachments.

7. Avoid loose fill, rocks and holes. They can be dangerous for loader operation or movement.

8. Be extra careful when working on inclines.

9. Allow for the loader length when making turns.

10. Stop the loader arms gradually when lowering or lifting.

11. Use caution when handling loose or shiftable loads.

12. Carry loader arms at a low position during transport.

13. Lower loader arms, stop engine, and lock brakes before leaving the tractor seat.

14. Operate the loader controls only when properly seated at the controls.

15. Do not use loader for handling large, heavy objects such as logs, oil drums, etc.

16. Handling large, heavy objects is dangerous due to:
*Possibility of rolling the tractor over.
*Possibility of upending the tractor.
*Possibility of the object rolling or sliding down the loader arms onto the operator.

17. Use large round hay bale handler attachment with bale retaining devices (grapples, bale spears, clamps, etc.) to
handle large round hay bales. Failure to use retaining devices could allow round hay bales to roll or fall down
loader boom arms onto the operator causing serious injury or death and equipment damage.

WARNING

3-4 EXTERNAL LOADER AND/OR TRAC-

TOR VALVE.

NOTE

When properly installed, the tractor remote valve
or external valve control lever/levers will control
the loader hydraulic circuits as described below.
Refer to tractor Operator’s Manual for further
explanation of tractor remote control
lever/levers.

IMPORTANT
Contaminants in hydraulic fluid can cause valve
spools to stick. BE ALERT when operating
loader and follow your tractor Operator’s Manual
hydraulic fluid maintenance schedule.

3-5 LOADER MOUNTED CONTROL
VALVE EQUIPPED WITH SINGLE LEVER
CONTROL HANDLE OR TRACTOR
REMOTE VALVE EQUIPPED WITH SIN­GLE LEVER CONTROL HANDLE

If your loader utilizes a loader control valve equipped
with single lever control handle or tractor remote
valve equipped with single lever control handle, it will
function as shown in Figure 3-1.

3-7 NEUTRAL POSITION

The loader external valve provided by Bush Hog has
a “neutral position” which prevents movement of the
loader or attachment. When the control handle is
manually released from the work position, the valve
spool will return to the neutral position.

3-8 FLOAT POSITION

The loader external valve provided by Bush Hog has
a “float position” incorporated into the lift cylinder cir­cuit which allows the loader to float. This float fea­ture is important for satisfactory operation when
scraping, sweeping, leveling, or any job where it is
necessary to follow the contour of the surface. To
activate the float position, lower the bucket or attach­ment and push the control handle all the way for­ward into detent. The valve will stay in float detent
position until the operator manually pulls the control
handle out of detent position to deactivate float.

3-9 REGENERATIVE VALVE POSITION

When the handle is pushed all the way to the right,
it will go past the dump detent position into the
regenerative position. This position requires the
operator to hold it in place. This feature enhances
the performance and speed of the dump procedure.

3-10 LOAD SENSE LOADER VALVE

IMPORTANT
If your loader is equipped with a load sense type
control valve it may demonstrate the following
operation characteristic. Attempting to raise the
boom by finely feathering the control lever may
actually allow the boom to lower very slowly. To
prevent this from happening, move the control
lever far enough to ensure that the boom raises.

3-11 LOADER OPERATION

Before operating the loader, fully raise and lower the
boom three or four times. Then raise the loader
bucket approximately four (4) feet above the ground
and cycle the bucket two or three times. Lower the
bucket or attachment to the ground. Check the trac­tor hydraulic fluid level and fill as required. Refer to
the tractor Operator’s Manual for the proper
hydraulic fluid and the correct hydraulic fluid level.

Figure 3-1

3-6 LOADER MOUNTED SERIES CON­TROL VALVE EQUIPPED WITH SINGLE
LEVER CONTROL HANDLE

If your loader utilizes a loader mounted series con­trol valve equipped with single lever control handle, it
will function as shown in Figure 3-2.

Figure 3-2

IMPORTANT
Always keep the cylinders in a retracted position
when the loader is not in use to guard against
rust and contamination which may cause dam­age to the cylinder rods and hydraulic system.

3-12 REMOVING AIR FROM HYDRAULIC
SYSTEM

Repeat raising and lowering the loader boom and
bucket operations until all the air is removed from
the system and the system responds properly.

3-13 HOSE IDENTIFICATION

Metal lines on the loader are color coded. Check
loader functions. Refer to instruction sheets for
hydraulic valve option on your loader.

3-14 BUCKET LEVEL INDICATOR ROD

A bucket level indicator rod (Figure 3-3), located on
the bucket cylinder, can be used to determine bucket
angle. Before beginning work, observe the position
of indicator rod with the bucket flat on the ground.
The “kink” in the indicator rod should be located in
the bracket slot. If the kink is not in centered in the
slot, readjust the bracket. Refer to the assembly
instructions. Raise boom to several different posi­tions and operate the bucket cylinders. Observe the
indicator rod. Once familiar with the indicator rod
positions, operation of the loader will be easier and
more efficient.

The text and illustrations on the following pages
offer suggested loader and tractor operating
techniques.

CAUTION

BEFORE LEAVING THE TRACTOR SEAT,
LOWER ATTACHMENT OR LOADER BOOM
TO GROUND, STOP ENGINE, LOCK
BRAKES, RELIEVE HYDRAULIC PRES­SURE, AND REMOVE KEY.

FILLING THE BUCKET
Approach and enter the pile with a level bucket.

Loaders with 1-lever control, ease lever back and
toward you to lift and rollback the bucket.

Loaders with 2-lever controls, ease both levers back
to lift and rollback the bucket.

The lift and rollback of the bucket will increase effi­ciency because...

...a level bucket throughout the lifting cycle resists
bucket lift and increases breakaway effort.

NOTE; Do not be concerned if the bucket is not
completely filled during each pass. Maximum produc­tivity is determined by the amount of material loaded
in a given period of time. Time is lost if two or more
attempts are made to fill the bucket on each pass.

LIFTING THE LOAD

WARNING

DO NOT LIFT OR CARRY ANYONE IN THE
BUCKET OR ON ANY OTHER PORTION OF
THE LOADER OR LOADER ATTACHMENT.
INADVERTENT MOVEMENT OF THE
LOADER OR ATTACHMENT COULD
RESULT IN SERIOUS INJURY OR DEATH
FROM FALLING OR CRUSHING.

MAKE SURE MATERIAL IN BUCKET CAN­NOT ROLL OUT AND DOWN ON TRACTOR
WHEN BUCKET IS RAISED TO FULL
HEIGHT. KEEP CLEAR OF OVERHEAD
OBSTRUCTIONS SUCH AS TREES, LIMBS
OR POWER LINES WHEN RAISING THE
BUCKET

CAUTION

When lifting the load, keep the bucket positioned to
avoid spillage.

CAUTION

DO NOT ATTEMPT TO LIFT BUCKET
LOADS IN EXCESS OF CAPACITIES
LISTED IN TABLE 1-1 TECHNICAL SPECI­FICATIONS.

16

CARRYING THE LOAD

Position the bucket as low as possible below the
level of the tractor hood for maximum stability and
visibility, whether the bucket is loaded or empty.

Use extreme caution when operating the loader on a
slope and keep the bucket as low as possible. This
keeps the bucket and tractor center of gravity low
and will provide maximum tractor stability.

CAUTION

OPERATING THE LOADER ON A HILLSIDE
IS DANGEROUS. EXTREME CARE IS
RECOMMENDED.

DO THIS NOT THIS

When transporting the load, keep the bucket as low
as possible to avoid tipping, in case a wheel drops in
a rut.

NOT THIS

DO THIS

DUMPING THE BUCKET

Lift the bucket high enough to clear the side of the
vehicle. Move the tractor in as close to the side of
the vehicle as possible, then dump the bucket.

LOWERING THE BUCKET

After the bucket is dumped, back away from the
vehicle while lowering and rolling back the bucket.

OPERATING WITH FLOAT CONTROL

During hard surface operation, keep the bucket level
and put the lift control in the float position to permit
the bucket to float on the working surface. If
hydraulic down pressure is exerted on the bucket, it
will wear faster than normal.

FLOAT

The float will also prevent the mixing of surface
material with stockpile material. The float position
will reduce the chance of surface gouging when
removing snow or other material.

LOADING FROM A BANK

Choose a forward gear that provides sufficient
ground speed for loading

Exercise caution when undercutting high banks. Dirt
slides can be dangerous. Load from as low as possi­ble for maximum efficiency. Loader lift and break­away capacity diminish as loading height is
increased.

It’s important to keep the bucket level when
approaching a bank or pile. this will help prevent
gouging the work area.

Another method for large dirt piles is to build a ramp
approach to the pile.

If the piles are too high and liable to cause cave-in,
use the loader to break down the sides until a slot
can be cut over the top.

Sidecutting is a good technique for cutting down a
big pile.

18

PEELING AND SCRAPING BACKFILLING

6”

Use a slight bucket angle, travel forward, and hold the
lift control forward to start the cut. Make a short, angle
cut approximately 6” deep and break-out cleanly.

With the bucket level, start a cut at the notch approx­imately 2” deep. Hold the depth by feathering the
bucket control to adjust the cutting lip up or down.
When the front tires enter the notch, adjust the lift
cylinder to maintain proper depth.

3RD CUT , 4TH CUT, ETC.

Make additional passes until the desired depth is
reached. During each pass, only use the bucket con­trol while at working depth. This will allow you to
concentrate on controlling the bucket angle to main­tain a precise cut.

LOADING LOW TRUCKS OR SPREADERS FROM
A PILE

For faster loading, minimize the angle of turn and
length of run between pile and spreader.

Backgrade occasionally with a loaded bucket to
keep the working surface free of ruts and holes.
Hold the lift control forward in float position so the
full weight of the bucket is scraping the ground.
Use only the heel of the bucket while backgrading.

IMPORTANT: To prevent damage to cylinders:
(1) Do not backgrade with bucket cylinders extended.
(2) Always backgrade with valve in float position.

Approach the pile with a flat bucket.

Poor methods actually move no more dirt and make
it more difficult to hold a level grade.

Do not use the bucket in the dumped position
for bulldozing or backgrading. This method,
shown above, will impose severe shock load­ings on the dump linkage, the bucket cylinder,
and the tractor.

HANDLING LARGE HEAVY OBJECTS

WARNING

Do not use front end loaders for handling
large heavy objects such as logs or oil
drums. Handle large round hay bales only
when loader is equipped with Bush Hog
Bale Spear Attachment.

Handling large heavy objects can be
extremely dangerous due to:

★ Possibility of rolling the tractor over.
★ Possibility of upending the tractor.
★ Possibility of the object rolling or sliding

down the loader arms onto the operator.

3-15 BALE SPEAR OPERATION

The bale spear (Figure 3-4) is intended for handling
large round bales. Before operation, set tractor
wheels to tractor manufacturer’s widest recommend­ed settings and add ballast as necessary to provide
adequate stability for handling round bales. It is rec­ommended that tractor be equipped with a ROPS
and seat belts. Approach bale from downhill side
with tractor in low gear. Run spears all the way

into bale with long spear as close to center as
possible. Lift bale just high enough for adequate
ground clearance to transport, maintaining good
visibility. Always carry load as low as possible
when transporting, for improved stability. Use

low gear on downhill grades. Unload round bales on
a level surface.

★ NEVER USE FORK LIFT ATTACH-

MENT TO LIFT OR SUPPORT
PEOPLE.

★ TRANSPORT LOADS LOW AND

SLOW.

★ AVOID CONTACT WITH POWER

LINES.

The fork lift attachment (Figure 3-5) is intended for
handling palletized material. It is recommended that
tractor be equipped with ROPS and seat belts. Use
the loader dump cylinders to give the forks the
desired tilt. Position the forks on their support rods to
the desired width so that the load will be carried
approximately equal on each fork. Position load as
far back as possible.

3-17 TRANSPORTING

When transporting on road or highway, day or night,
use tractor flashing warning lights unless prohibited
by law. Carry load as low as possible maintaining
adequate ground clearance and good visibility.
Reduce tractor ground speed when carrying a load.
Take extra care when traveling over rough terrain or
on slopes.

WHEN TRANSPORTING A LOAD, KEEP
THE ATTACHMENT AS LOW AS POSSIBLE
TO RESIST TIPPING IN CASE A WHEEL
DROPS IN A RUT.

5-2 TRACTOR BALLAST

Tractor weignt bracket may be left in place on cer­tain tractor models with loader mounted. Front trac­tor weights can only be used when the loader is
parked. Weights must be removed before remount­ing loader or serious damage will occur to loader or
tractor front axle due to excessive weight.

The use of adequate rear counterweight to counter­balance for maximum loader capacity is required for
safe loader operation. Weight added to the rear of
the tractor provides better traction and easier, more
efficient loader operation.

IMPORTANT
Do not exceed the maximum load capacity of the
tires on your tractor. Refer to the Tire and Wheel
Specifications in your Tractor Operator’s Manual
for more information.

IMPORTANT
This loader has both standard and metric fasten­ers. Verify that the proper fasteners are placed in
the correct locations. Do not tighten any bolts
firmly until all components are attached onto the
tractor.

tion shown in Fig. 1 if necessary for better access to the controls). If the tractor has a

floor matt, use the support mount as a template and mark the area around the base of the
support mount where it contacts the matt. Cut the matt on the marked area and remove the
cut out piece of matt.

4. It will be necessary to remove the support mount from the support tube to perform this step.
Position support mount on the cab floor board and use the mount as a template. Drill four

3/8” holes in line with the four slotted holes in the support mount. Mark the center of the 1
1/4” hole in the support mount on the floor board as close as possible to the hole in the sup-

port mount. Use a hole saw and cut a 1

1/4” hole that aligns with the large hole in the sup

port mount (Refer to Fig. 1).

The POWER BEYOND KIT is only required if connecting to an open center tractor hydraulic system. The use of a
power beyond kit allows the connection of the Bush Hog optional control valve to the tractor hydraulics without using the
remote controlled outlets on the tractor. It’s purpose is to protect the normal return port of the Bush Hog valve from back
pressure. Connection to the tractor remove provides this protection through the tractor remote control valve.

Bush Hog now provides two styles of Walvoil optional control valves: one for standard mounts and one for cable control.
The illustrations show both valves and the hose routing for both. The fittings required to connect the hoses to both
valves are provided in the kit. The power beyond plug for each valve is included in the valve kit ordered separately.

Three lines must be connected to the tractor system. Each line serves a specific purpose and proper plumbing is
essential. The proper location for the connections to the tractor hydraulic system must be obtained from the tractor man­ufacturer or local tractor dealership.

LINE A - PRESSURIZED SUPPLY LINE — Supplies oil from the pump to the pressure port of the control valve.
This line is the pressurized supply line to the valve when the handle on the optional control valve is activated to
move the boom or bucket cylinder.

LINE B - PRESSURIZED RETURN LINE TO TRACTOR SYSTEM — Returns oil to the tractor system when the
optional control valve is in the neutral position. This line will feel any back pressure generated by operation of
any other tractor system hydraulic function.

LINE C - NON PRESSURIZED RETURN LINE — Returns oil to the tractor system when the optional control
valve is activated to extend or retract the boom or bucket cylinders. This line must be connected to the tractor
system to provide a DIRECT

return of the oil to the tractor sump or oil supply tank.

HOSE AND COUPLER ASSEMBLY

The three hydraulic hoses are supplied with reusable couplings for one end while the other end has permanently
installed couplings. The hose length must be determined for your tractor model.

BE SURE

TO MAKE HOSES LONG ENOUGH to attach to tractor when loader is disconnected from tractor and is on its

leg stands.

1. Attach permanent coupler ends of hose to fittings, installed in the pressure, sump and power beyond ports of the
valve. The long hose should be attached to the sump port. See back page for instructions on installing reusable
coupling.

2. Determine required length of each hose, attach reusable couplings to hoses per instructions shown.

3. Install the three adaptors furnished into the hoses on the reusable coupling end. Place the 3/4” JIC end of the

adaptor to hose.

4. Attach two quick coupler female ends to adaptors on the pressure hose and the sump hose. Install a quick coupler
male end, to return pressurized return inlet hose (power beyond hose).

5. Attach two quick coupler male ends to pressure hose and sump hose from tractor. Attach one quick coupler female
end to tractor return outlet.

DISCONNECTING LOADER VALVE FROM TRACTOR

The pressurized supply line, A, and the pressurized return line (power beyond port) must be connected when the loader
valve is removed from the tractor. Insure female and male quick couplers are installed per paragraph 4 above. Failure
to make this connection will result in damage to the tractor hydraulic system.

DESCRIPTION

The hydraulic self-leveling option is designed to be incorporated into Bush Hog’s standard loader hydraulic circuit. A dual self­level valve controls flow throughout the system so as to maintain a nearly constant position of the loader attachment relative
to the ground. The valve performs this function in both the raising and lowering mode. The bucket (or other attachment) may
be operated at any time, independent of the self-level valve, giving the operator the ability to reposition it throughout the work
cycle.

: IF THE LOADER ATTACHMENT ROLLS COMPLETELY BACK WHILE LOWERING THE BOOM, DOWNWARD

NOTE
MOTION WILL CEASE; ROLL THE ATTACHMENT FORWARD TO CONTINUE LOWERING.

ADJUSTMENT

Since the same self-level valve is used on different Bush Hog loaders, adjustment of the valve may be required when installed
on one particular loader or the other to obtain a preferred performance. There are two separate adjustment screws, one for the
raising mode and one for the lowering mode. Remove the dust cap to access the adjustment screw and loosen the jam nut
prior to adjusting. Adjustments should be made in 1/4 turn increments to achieve the desired motion according to the following
logic:

RAISING: Clockwise - More Rollback

Counterclockwise - More Dump

LOWERING: Clockwise - More Dump

Counterclockwise - More Rollback

Being a “needle valve” type adjustment, a point is reached when backing the adjustment screw out further (counterclockwise)
has no effect. The maximum effective range of adjustment in this situation is approximately 2-3 turns.
