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 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.
5
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, 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.

LEVER CONTROL HANDLE
WARNING
ESCAPING HYDRAULIC FLUID UNDER
PRESSURE CAN HAVE SUFFICIENT FORCE
TO PENETRATE SKIN, CAUSING SERIOUS
PERSONAL INJURY. BEFORE APPLYING
PRESSURE TO SYSTEM, BE SURE ALL
CONNECTIONS ARE TIGHT AND THAT
LINES, TUBES, AND HOSES ARE NOT DAMAGED. FLUID ESCAPING FROM A VERY
SMALL HOLE CAN BE ALMOST INVISIBLE.
USE A PIECE OF CARDBOARD OR WOOD,
RATHER THAN HANDS, TO SEARCH FOR
SUSPECTED LEAKS. IF INJURED BY
ESCAPING FLUID, SEE A DOCTOR AT
ONCE. SERIOUS INFECTION OR REACTION
CAN DEVELOP IF PROPER MEDICAL
TREATMENT IS NOT ADMINISTERED IMMEDIATELY.
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
3-7 NEUTRAL POSITION
3-4 EXTERNAL LOADER AND/OR TRACTOR VALVE.
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.
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.
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.
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.
3-9 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.
Figure 3-1
14
3-10 LOADER OPERATION
3-12 HOSE IDENTIFICATION
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.
Metal lines on the loader are color coded. Check
loader functions. Refer to instruction sheets for
hydraulic valve option on your loader.
3-13 BUCKET LEVEL INDICATOR ROD
A bucket level indicator rod (Figure 3-3), located on
the loader frame, can be used to determine bucket
angle. Before beginning work, observe the position
of indicator rod with the bucket flat on the ground.
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.
CAUTION
BEFORE LEAVING THE TRACTOR SEAT,
LOWER ATTACHMENT OR LOADER BOOM
TO GROUND, STOP ENGINE, LOCK
BRAKES, RELIEVE HYDRAULIC PRESSURE, AND REMOVE KEY.
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.
The text and illustrations on the following pages
offer suggested loader and tractor operating
techniques.
3-11 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.

The text and illustrations that follow offer suggested loader and tractor
operating techniques.
FILLING THE BUCKET
Approach and enter the pile with a level bucket.
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.
Ease lever back and toward you to lift and rollback
the bucket.
NOT THIS
1-LEVER CONTROL
ROLLBACK
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.
LIFT
16
LIFTING THE LOAD
CAUTION
OPERATING THE LOADER ON A HILLSIDE
IS DANGEROUS. EXTREME CARE IS
RECOMMENDED.
WARNING
DO NOT LIFT OR CARRY ANYONE IN THE
BUCKET OR ON ANY OTHER POSITION
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
DO THIS
NOT THIS
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.
When transporting the load, keep the bucket as low
as possible to avoid tipping in case a wheel drops
into a rut.
NOT THIS
When lifting the load, keep the bucket positioned to
avoid spillage.
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.
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.
LOWERING THE BUCKET
After the bucket is dumped, back away from the
vehicle while lowering and rolling back the bucket.
FLOAT POSITION
LOWER
DUMP
1-LEVER
CONTROL
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.
ROLLBACK
17
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.
FLOAT
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.
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 is important to keep the bucket level when
approaching a bank or pile. This will help prevent
gouging the work area.
18
PEELING AND SCRAPING
BACKFILLING
DO THIS
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.
NOT 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.
IMPORTANT: To prevent damage to cylinders:
(1) Do not backgrade with bucket cylinders extended.
(2) Always backgrade with valve in float position.
3RD CUT , 4TH CUT, ETC.
Approach the pile with a flat bucket.
DO THIS
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.
19
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.
Leave dirt in the bucket because dumping on each
pass wastes time.
★ Possibility of the object rolling or sliding
down the loader arms onto the operator.
3-14 TRANSPORTING
DITCH
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 visibility.
Reduce tractor ground speed when transporting a
load. Take extra care when traveling over rough
terrain or on slopes.
SOIL PILE
CAUTION
WHEN TRANSPORTING THE LOAD, KEEP THE
BUCKET AS LOW AS POSSIBLE TO RESIST TIPPING IN CASE A WHEEL DROPS IN A RUT. THIS
WILL AVOID TIPPING AND POSSIBLE INJURY.
Operate at right angles to the ditch. Take as big a
bite as the tractor can handle without lugging down.
NOTE
DITCH
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.
3-15 FORK LIFT OPERATION (M246 ONLY)
WARNING
TO AVOID SERIOUS INJURY OR DEATH:
★ NEVER LIFT LARGE ROUND HAY
BALES OR OTHER LOADS ON THE
FORK LIFT ATTACHMENT THAT
COULD ROLL BACK ONTO TRACTOR OPERATOR AREA.
★ NEVER USE FORK LIFT ATTACHMENT TO LIFT OR SUPPORT PEOPLE.
★ TRANSPORT LOADS LOW AND SLOW.
★ AVOID CONTACT WITH POWER LINES.
Leave dirt which drifts over the side of the bucket for
final clean-up.
The fork lift attachment (Figure 3-4) 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.
Pile dirt on the high side for easier backfilling on a
slope.
20
3-16 QUICK HITCH OPERATION (M246 ONLY)
Figure 3-4
Fork Lift Attachment
The quick hitch (Figure 3-5) is designed to allow
easy mounting and dismounting of skid steer
attachments from loader. With attachment on flat,
level surface, mount as follows:
Tilt quick hitch slightly forward at top and slowly
