IMPORTANT SAFETY PRECAUTIONS
This symbol is used to call attention to safe-
ty 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 seri-
ous 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. When operating loader directly off tractor remotes always remove or lockout detent on tractor’s hydraulic valves.
This allows levers return to neutral position when released.
4. Add wheel ballast or rear weight for stability.
5. Move wheels to the tractor manufacturer’s widest recommended settings to increase stability.
6. For better stability, use tractor with wide front axle rather than tricycle front wheels.
7. Move and turn the tractor at low speeds.
8. 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 serv ing, repairing, or making adjustments
to the equipment.
9. 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 seri-
ous 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

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.

OPERATING INSTRUCTIONS
CAUTION
DO NOT LIFT ROUND HAY BALES. ROUND
BALES CAN ROLL DOWN LOADER ARMS
CAUSING SERIOUS INJURY OR DEATH TO
OPERATOR.
3-1 GENERAL SAFETY
Only qualified people familiar with this 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. Check for ditches, stumps, holes or other
obstacles that could upset tractor or damage loader.
Fluid and/or weights for rear tires is recommended
for added stability. See tractor operator’s manual.
Three point hitch mounted weights are available from
your Bush Hog dealer. Always turn off tractor engine,
set parking brake and lower loader to ground before
dismounting tractor. See page 4 for additional safety
precautions.
3-2 OPTIONAL BUCKET LEVEL GAUGE ROD
An optional level indicator gauge rod (Figure 3-1) can
be used to determine bucket angle.Before beginning
work, observe the position of the gauge rod with
bucket flat on the ground. Raise boom to several dif-
ferent positions. At each position, level bucket then
observe gauge rod. Once familiar with the gauge rod
positions, operation of loader will be easier and more
efficient.
3-3 OPERATION
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.
The following text and illustrations offer suggested
loader and tractor operating techniques.
11
NOTE: Do not be concerned if the bucket is not com-
pletely filled during each pass. Maximum productivi-
ty 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.
FILLING THE BUCKET
Approach and enter the pile with a level bucket.
Ease lever back and toward you to lift and rollback
the bucket.
1-LEVER CONTROL
ROLLBACK LIFT
The lift and rollback of the bucket will increase
efficiency because...
DO THIS
... a level bucket throughout the lifting cycle resists
bucket lift and increases breakaway effort.

LIFTING THE LOAD
WARNING
DO NOT LIFT OR CARRY ANYONE IN THE
BUCKET OR ON ANY OTHER POSITION
OF THE LOADER OR LOADER ATTACH-
MENT. INADVERTENT MOVEMENT OF
THE LOADER OR ATTACHMENT COULD
RESULT IN SERIOUS INJURY OR DEATH
FROM FALLING OR CRUSHING.
CAUTION
MAKE SURE MATERIAL IN BUCKET CAN-
NOT 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.
When lifting the load, keep the bucket positioned to
avoid spillage.
CAUTION
DO NOT ATTEMPT TO LIFT BUCKET
LOADS IN EXCESS OF 625 LBS. FOR
THE 1846 OR 1000 LBS. FOR THE 2246.
CARRYING THE LOAD
Position the bucket just 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, 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.
FLOAT
SURFACE 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 possi-
ble for maximum efficiency. Loader lift and breakaway
capacity diminish as loading height is increased.
It is 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 pile sides 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.
13

PEELING AND SCRAPING
6”
BACKFILLING
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.
DO THIS
NOT THIS
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 trac-
tor.
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 approx-
imately 2” deep. Hold the depth by feathering the
bucket control to adjust the cutting lip up or down.
When the front tiress 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 con-
trol while at working depth. This will allow you to
concentrate on controlling the bucket angle to main-
tain 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. 14

Leave dirt in the bucket because dumping on each
pass wastes time.
Operate at right angles to the ditch. Take as big a
bite as the tractor can handle without lugging down.

DITCH
Leave dirt which drifts over the side of the bucket for
final clean-up.
Pile dirt on the high side for easier backfilling on a
slope.
HANDLING LARGE HEAVY OBJECTS
WARNING
Do not use front end loaders for handling large,
heavy objects such as large, round or rectangular
bales, logs and oil drums.
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.
3-4 TRANSPORTING
When transporting on road or highway, day or
night, use tractor flashing warning lights unless pro-
hibited by law. Carry load as low as possible main-
taining adequate ground clearance and visibility.
Reduce tractor ground speed when transporting a
load. Take extra care when traveling over rough
terrain or on slopes.
CAUTION
WHEN TRANSPORTING THE LOAD, KEEP THE
BUCKET AS LOW AS POSSIBLE TO RESIST TIP-
PING, IN CASE A WHEEL DROPS IN A RUT. THIS
WILL AVOID TIPPING AND POSSIBLE INJURY.
3-5 LOADER DETACHING AND STORAGE
NOTE
When loader hydraulics are disconnected
from tractor the tractor hydraulic circuit
must be completed. Failure to do so will
result in tractor hydraulic pump damage.
A. Remove parking stands from storage. Raise
boom and install as shown in Figure 2-1.
B. Lower boom until parking standss contact ground.
C. Extend bucket cylinders (dump) until cutting edge
of bucket is firmly on the ground.
D. Remove pin from front mounting bracket.
E. Remove nuts and clamps securing loader sub-
frame to rear mounting bracket. (Figure 2-4)
F. With tractor at IDLE SPEED carefully roll bucket
back until subframe raises off rear bracket.
G. Carefully activate boom cylinders until cross tube
is free of pressure within front bracket channel.
H. Disconnect hydraulic hoses.
I. Carefully back tractor out of loader.
J. Pin clamps back to subframe and place pin back in
front mounting bracket for storage.
K. Clean dirt and debris from loader. Dirt will hold
moisture and cause rust.
L. If loader is to be stored for an extended period of
time, perform lubrication per paragraph 4-2 Also apply a
coat of heavy grease to exposed cylinder rods to prevent
rusting.
WARNING
NEVER STAND UNDER LOADER WHILE
INSTALLING/REMOVING PARKING STANDS.
