High Lift Loaders
High lift loader require tractors with a long wheel base.
The rear wheels need to be set out all the way or prefer-
ably dual rear wheels and adequate ballast. (See ballast
calculations in your loader’s operator manual.)
The front wheels are
the fulcrum when
raising a load.
You must have
sufficient leverage and
ballast to offset the loader
in front of the front tires.
Extreme care and slow
speed must be used when
raising and dumping a load.
Monitor the load at all times.
Detach Loader Safely
Detach loader on a firm and level surface. Loader
may fall over if detach on unlevel or a soft surface.
Be sure people, live-
stock and pets are clear
of machinery.
Relieve hydraulic
pressure before
disconnecting
hydraulic hoses.
Avoid Rollover
Your tractor may rollover,
resulting in death or serious
injury. To avoid rollover:
• Travel at a slow speed;
• Carry loads close to the
ground;
• Avoid sharp turns and
sudden movements on slopes;
• Avoid holes, ditches and other obstructions which may
cause the tractor to rollover;
• Balance load so weight is evenly distributed and load is
stable;
• Be extra careful when operating on slopes and do not
operate on excessively steep slopes;
• Do not exceed the load capacity of your equipment;
• Be certain tractor tire spacing and rear ballast are correct
before using equipment;
• Approach large round or square bales on a slope
with the tractor facing uphill.
Avoid Power Lines & Underground Utilities
Death or serious injury
can result if equip-
ment comes near
or contacts power
lines.
Electrocution can
occur without direct contact.
Check clearance before raising equipment.
Have local utilities locate and
mark under ground wires,
cables, pipelines and
other hazards before
digging.
DO NOT leave the operator’s seat if any part of the
equipment contacts electric lines or cables.

Transport Loads Safely
Use the proper attachment to lift and carry the load.
Follow the instructions in the appropriate operator’s
manual for any loader attachments.
Carry loads low and slightly rolled back.
Travel SLOW and avoid slopes.
Avoid High Pressure Fluids
Escaping fluid under
pressure can penetrate
the skin causing serious
injury.
Avoid the hazard by re-
lieving pressure before
connecting or discon-
necting hydraulic lines.
Tighten all connections before applying pressure.
Search for leaks with piece of cardboard or wood. Protect
hands and body from high pressure fluids.
If an accident occurs, see a doctor immediately. Any fluid
injected into the skin must be surgically removed within a
few hours or serious infection may result. Doctors unfamiliar
with this type of injury should reference a knowledgeable
medical source.
DO NOT mount a valve with direct mount joystick inside
the tractor cab. Use only a remote cable inside cab.
Check the loader response to the control lever move-
ment. The loader should respond according to the
ASAE standards shown. If response is incorrect,
check the hydraulic hose connections at the trac-
tor and manifold and correct if necessary. 1-Lever
control functions are shown throughout the manual,
refer back to this section for operation regarding the
2-Lever control.

Prevent Falling Loads
ALWAYS secure the
load at the source.
Round bales, square
bales, posts, stones,
logs and other objects can fall
or roll from a raised loader or
attachment, which may crush
the operator or bystanders.
Handle all raised loads with
caution. Keep eyes on load
while raising or lowering.
• DO NOT carry items that may shift in the loader
bucket or attachment.
• DO NOT handle round or square bales unless the
loader is equipped with the proper bale handling at-
tachment.
• DO NOT handle bales with the pallet fork attachment.
• NEVER travel with a raised load.
• ALWAYS carry loads low and close to the ground.
Raised Loader
A raised loader can fall unexpectedly, resulting in
death or serious injury.
NEVER enter the area
under a raised
loader or
attachments.
Lower bucket or
attachments to the ground, place tractor transmission
in park, shut off engine and remove key before servic-
ing loader or attachments.
Detach loader from tractor to service the tractor.
The loader lift arms and attachments may be con-
trolled by mechanical controls, electrical controls, or a
combination of mechanical/electrical control devices.
Movement of the controls for the lift arms and the
attachments shall be of the NON-DETENTED TYPE,
except for the float position control, which may be held
in position by a detent. This does not apply to purpose
design automated functions e.g. return to dig.

SECTION 2: SAFETY
BALLAST refers to cast weights or fluid added to rear tractor tires. Hitch ballast refers to a weight or an implement attached to the tractor three-point hitch.
GROSS VEHICLE WEIGHT (GVW)
is the sum of front and rear axle weight caused by the mass of the tractor, loader, attachment, payload, ballast and hitch ballast.
The operational ballast criterion has been met when
a minimum of 25% of the gross vehicle weight is
retained on the rear axle in a static condition on
level ground.
•A mass equivalent to the Lift Capacity maximum height
should be placed in the loader bucket, with the boom
raised until the bucket pivot pin is the same distance
from the ground as the boom pivot (farthest forward
position). The rear axle weight and gross vehicle weight
should be measured on hard level ground (+ 1o) under
these conditions. See Figure 1.
•Ballast must be added to the rear wheels and/or hitch
until the rear axle weight on level ground is a minimum
of 25% of the gross vehicle weight. Ballast added to
the rear hitch should be kept as low as practical.
•When a loader is used in a dedicated situation,
an operator may determine the appropriate ballast,
based on the maximum load to be carried.
•We recommend ballast, based on the criteria listed
in above and knowledge of the physical character-
istics of the tractor.
This engineering practice is intended as a guide to determine the minimum ballast and tread settings recommended for the operation of a front loader
mounted on a 2WD tractor or a tractor with front assist. These ballast and tread setting recommendations are intended to reduce the risk of vehicle over-
turn during typical operation.
The rear wheel width is the most important specification to the balance of your tractor loader operation.
Always use approved ROPS and fasten your seat belt.
Minimum tread settings are recommended to provide static stability on a side slope up to 15 degrees under
proper rear ballast conditions listed in above. If minimum tread settings are not available in your mounting
instructions, minimum rear tread settings should be selected from the following chart:
Minimum Tread Settings
STEP 1: Put weight in the bucket equiv-
alent to the lift capacity of the loader at
full lift height. The lift capacity
can be found in several locations:
• Operators manual
• Company Literature
• Visit us online at www.loaders.com
• Or Call Us at 712-423-2762
STEP 2: At the scale get the gross
vehicle weight (GVW) with the loader
raised so the bucket pivot pin is as high
as the boom pivot pin.
See Figure 1 .
Then weigh the rear axle (R).
STEP 3: Formulas to figure ballast.
GVW x 25% = Required Rear Axle
Weight (RRAW)
< IS LESS THAN > IS GREATER THAN
If R>RRAW = No Ballast Required
If R<RRAW = Ballast Required
Figure Rear Ballast Required (RBR):
RRAW - R = RBR
RBR x 133% = Ballast Required
Note:Since adding ballast increases the total
weight adding the difference will not be enough.
You need to add approximately 133% of the dif-
ference. Depending on where you add the ballast
in respect to the rear axle the amount of weight
may vary.
Determination of Ballast Three Simple Steps
TRACTOR
DAMAGE.
To avoid tractor damage use hitch ballast.
Failure to use ballast can cause the front axle
or other tractor components to be overloaded
during loader operation.
CRUSHING
HAZARD.
To prevent personal injury or death from trac-
tor loader roll-over, add the recommended
amount of ballast to the tractor. Always use a
ROPS and wear a seatbelt.

SECTION 4: OPERATION
1-LEVER CONTROL
ASAE standard S335.4 shown in illustration
Hydraulic Control Functions
Check the loader response to the control lever movement. The loader should respond according to the
ASAE standards shown. If response is incorrect, check the hydraulic hose connections at the tractor and
manifold and correct if necessary. 1-Lever control functions will be shown throughout the manual, refer back
to this section for operation regarding the 2-Lever control.
RAISE - Pull control lever rearward to raise the bucket
or attachment.
LOWER - Push control lever forward to lower the
bucket or attachment.
DUMP - Move the control lever to the right to dump the
bucket or attachment.
ROLLBACK - Move control lever to the left to roll the
bucket or attachment back after dumping.
FLOAT - The float position allows the bucket or attach-
ment to follow the contour of the surface. To place

Rotational Level Indicator Method of CALIBRATION
Flat Face Hydra-Snap™
THE ROTATIONAL LEVEL INDICATOR is used to
determine the attachment angle in relation to the surface.
Your loader is equipped with a multi-hose coupling, one handle Flat Face Hydra-Snap™ manifold.
The Flat Face Hydra-Snap™ is spill-free, couples under pressure, and saves time and environment.
Place transmission in park & relieve LIFT cylinder pressure
before connecting or disconnecting the Hydra-Snap™ manifold.
1. TO DISCONNECT:
Close #1 shut off valve.
Open #2relieve valve.
Rotate handle “slowly” to
disconnect. Store in the
parking location while
loader is dismounted.
Close cover to protect
ports from dust and debris.
2. TO CONNECT: Hold handle at 12 o’clock position and
rotate handle clockwise “slowly” until couplers and electronic
circuit engage. Close #2relief valve. Open #1shut off valve
to bucket cylinders. Mount the loader.
Note: See tractor Operator’s Manual for correct procedure. Some trac-
tors require engine to be off to relieve hydraulic pressure, while others
require it to be running.
Optional Synchronizer Bar
If your loader is equipped with a synchronizer bar mounted
between the remote control couplers, it allows them to work in
unison for quicker attachment swaps between jobs.

SECTION 4: OPERATION
Two types of leveling systems available for loaders:
• Standard
• Level UP Advantage™
STANDARD - self-leveling requires the operator to
level the load as it is raised.
Ease the single lever control back and
away from you to lift and level the load
as it is raised.
LEVEL UP ADVANTAGE™ - the hydraulic load level-
ing system automatically levels the load as the loader
is raised.
The operator simply pulls back on the
control lever and the load will raise and
remain level.
Lifting The Load
Loader Operation
Refer to the tractor operator’s manual for a safe RPM to
run the tractor engine.
Fill The Bucket From A Pile
Approach and enter the pile straight in with a level bucket.
Ease the control lever back and toward you simultane-
ously to raise and rollback the bucket to breakaway the
load from the pile.
Raise and rollback the bucket to increase
your efficiency when filling the bucket.
A level bucket throughout the lifting cycle resists lifting
and will require more power to break away.

To prevent damage
to loader and/or
tractor:
• Stop loader
gradually
when lowering
heavy loads.
• NEVER drop a load
and “catch” hydraulically.
• Hydraulically stopping a load after it has gained downward
momentum can damage the loader and/or tractor.
Handle all raised loads with caution. Keep eyes on load
while raising or lowering to be sure the load does not fall
out of the back of the bucket.
NEVER travel with a
raised load. Raise the
load when approaching
equipment. Keep loads
close to work area to
minimize travel time.
Keep loading area level
to prevent rollover. Do not raise load higher than required
while dumping.
Dump the load by moving the control level
outward.
After dumping the load, back away and
move the single lever control forward and
inward to lower and rollback the bucket.
CARRY LOAD LOW DON’T CARRY HIGH
Dumping The LoadCarrying The Load
Position the load as low as possible below the level of the
tractor hood for maximum stability and visibility.
Use extreme caution when operating on a slope. Keep
the load as low as possible. This keeps the center of
gravity low and provides maximum tractor stability.
To prevent
electrocution:
• NEVER let

CRUSHING HAZARD.
To prevent tractor roll over:
• Travel at slow speed;
• Carry loads close to the ground;
• Avoid sharp turns and sudden
movements on slopes;
• Balance load so weight is
evenly distributed and load
is stable;
• Avoid holes, ditches and other obstructions which
may cause the tractor to rollover;
• Be extra careful when operating on slopes and do not
operate on excessively steep slopes;
• Do not exceed the load capacity of your equipment;
• Be certain tractor tire spacing and rear ballast are
correct before using equipment;

Backfill and Backgrade
BACKFILLING -
To reduce the risk of a
trench caving in, keep
tractor tires back from
the trench, the same
distance as the depth
of the trench.
Approach pile with level bucket.
Operate at right angles to trench
taking as much material
as tractor and loader
can handle.
BACKGRADING - Backgrade with heel of bucket only, or
use optional BACKDRAG BLADE. Place control lever in
float position so bucket follows the contour of the surface.
Angle the bucket slightly, move forward slowly and lower
the bucket to start the cut.
When the bucket has penetrated the material, level the
bucket and move forward until the bucket is full. Use
the bucket control lever to control the
depth of the cut. Use FLOAT to
reduce down pressure and
wear on the cutting edge
when scraping.
Make additional passes until desired depth is reached.
During each pass, use only the
bucket cylinder control while at
working depth to control the
bucket angle to maintain
a precise cut.
Peeling and Scraping
While working on a hard surface, level the bucket and
place control lever in float detent. This will allow the
bucket to “float” and follow the surface contour.
To place control lever in float, lower bucket or attachment
and push control lever fully forward into detent. The
control lever will remain in detent until manually pulled
back out of detent to deactivate float. Using float will also
prevent surface gouging and the mixing of the surface
material with the stockpile material.
Operating With Float Control
TIP Pushing with the material in the bucket will save time.
To prevent electrocution:
• NEVER let equipment near or
contact power lines.
• Electrocution can occur with-
out direct contact.
• ALWAYS check clearance before raising equipment.
• DO NOT leave operator’s seat if any part of
equipment contacts power lines or cables.
• ALWAYS have local utilities
locate and mark underground
wires, cables, pipelines and
other hazards before digging.
ELECTROCUTION
HAZARD.
DANGER
Example: If the trench is 3
feet deep (B), the tractor tires
must stay 3 feet (A) from the trench.
• Backfilling and backgrading with the bucket dumped
may damage the bucket control cylinders.
• If bucket hits a solid object while INCORRECTLY
positioned, you will damage your cylinders, linkage
and/or cutting edge.
• Backfill and backgrade with the bucket level.
