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 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 storage 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 manual 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. It is recommended that tractor be equipped with Rollover Protective System (ROPS) and a seat belt be used for 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.
4
SAFETY PRECAUTIONS CONTINUED
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 or fork.
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.

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.
BUCKET LEVEL INDICATOR
BLI (bucket level indicator) rod has been preassembled to loader linkage pin at the factory.
BLI (bucket level indicator) must be adjusted during
initial loader set up. Adjust the BLI as follows:
Position the bucket level on the ground. Loosen the
BLI clamp holding the BLI tube, and align the BLI
tube so that it is flush with end of the BLI rod, then
retighten BLI clamp. When operating loader, use the
attachment cylinder controls to align the BLI rod so
that it is flush with the end of the BLI tube. This will
inform the operator that the bucket and/or attachment bottom is level with ground. Refer to Figure 4.
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.
Bucket Level
Indicator
INITIAL LOADER OPERATION
Before operating the loader, fully raise and lower the
boom two or three times. Then raise the loader
bucket approximately four (4) feet above the ground
and cycle the bucket cylinders 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 Manual for
the proper hydraulic fluid and the correct hydraulic
fluid level.

REMOTE HOSES SUPPORT
THIRD CYLINDER TUBE KIT
(OPTIONAL)
After installing loader onto tractor, raise the loader to
full height, stop engine, lock brakes, and remove
key. Then gather remote hoses and install nylon tie
through hose support hole located in right hand
loader subframe. Secure hoses as shown. This will
allow remote hoses to be supported by loader frame
instead of loader steel tubing. Refer to Figure 5.
Install two steel tubes to inside of right hand loader
boom. Then connect the two hoses and fittings to
the front of the steel tubes. Refer to Figure 6 for further installation instructions.

Tighten hardware to torque values as specified in
the Torque Chart, page 43 unless otherwise specified.
IMPORTANT: Lower the loader boom to the
ground and relieve pressure in loader hydraulic
lines prior to doing any service or maintenance
operations on the tractor or loader.
Check the tractor hydraulic fluid level as specified in the tractor Operator Manual.
With the engine off and the bucket on the ground,
inspect all hoses for cuts or wear. Check for signs of
leaks and make sure all fittings are tight.
NOTE: When checking hydraulic system fluid
level, the loader boom must be on the ground
with the bucket or attachment resting flat on a
level surface.

5. OPERATING INSTRUCTIONS
OPERATION
GENERAL SAFETY
The loader should be operated with the tractor
engine running at 1200-1700 rpm. Excessive speeds
are dangerous and may cause bucket spillage and
unnecessary strain on both the tractor and loader.
Only qualified people familiar with this operator’s
manual should operate this machine. Operator
should wear hard hat, safety glasses and safety
shoes. The operator should read, understand and
practice all safety messages shown on the caution,
warning and danger decals affixed to the loader to
avoid serious injury or death. It is recommended that
tractor be equipped with Rollover Protective System
(ROPS) and a seat belt be used per tractor manufacturer’s recommendations. Check for ditches,
stumps, holes or other obstacles that could upset
tractor or damage loader. Always turn off tractor
engine, set parking brake and lower loader to ground
before leaving tractor operator’s seat.
When operating in temperatures below 30°F, run the
tractor engine belolw 1200 rpm until the hydraulic
fluid temperature exceeds 30°F.
The following text and illustrations offer suggested
loader and tractor operating techniques.
BUCKET LEVEL GAUGE ROD
The bucket level gauge rod (Figure 4, page 13) can
be used to determine bucket angle. Before beginning work, observe the position of gauge rod with
bucket flat on ground. Raise boom to several different positions. At each position, level bucket, then
observe gauge rod. Once familiar with the gauge rod
positions, operation of the loader will be easier and
more efficient.
16
FILLING THE BUCKET
Approach and enter the pile with a level bucket.
...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.
Loaders with 1-lever control, ease lever back and
toward you to lift and rollback the bucket.
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.
CAUTION
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
Loaders with 2-lever controls, ease both levers back
to lift and rollback the bucket.
When lifting the load, keep the bucket positioned to
avoid spillage.
The lift and rollback of the bucket will increase efficiency because...
CAUTION
DO NOT ATTEMPT TO LIFT BUCKET
LOADS IN EXCESS OF CAPACITIES
LISTED IN TECHNICAL SPECIFICATIONS.
17
CARRYING THE LOAD
DUMPING THE BUCKET
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.
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.
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.
LOWERING THE BUCKET
After the bucket is dumped, back away from the
vehicle while lowering and rolling back the bucket.
CAUTION

ROLLBACK
RAISE
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
Sidecutting is a good technique for cutting down a
big pile.
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.
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.
FLOAT
SURFACE MATERIAL
LOADING FROM A BANK
Choose a forward gear that provides sufficient
ground speed for loading.
Another method for large dirt piles is to build a ramp
approach to the pile.
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.
19
PEELING AND SCRAPING
BACKFILLING
6”
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.
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.
IMPORTANT: To prevent damage to cylinders:
(1) Do not backgrade with bucket cylinders extended.
(2) Always backgrade with valve in float position.
DO THIS
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.
Approach the pile with a flat bucket.
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
NOT THIS
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.
For faster loading, minimize the angle of turn and
length of run between pile and spreader.
20
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 OR BUCKET WITH 4
TINE GRAPPLE.
Leave dirt in the bucket because dumping on each
pass wastes time.
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.
DITCH
SOIL PILE
BACK GRADING
When back grading, the angle between the bottom
of the bucket and the ground must not be more than
15 degrees. Refer to Figure 1.
Operate at right angles to the ditch. Take as big a
bite as the tractor can handle without lugging down.
Failure to follow these instructions could cause
loader attachment cylinders to fail and void warranty.
DITCH
Leave dirt which drifts over the side of the bucket for
final clean-up.
