MANDATORY SAFETY SHUTDOWN PROCEDURE
BEFORE unclogging, cleaning, adjusting, lubricating or servicing the unit:
1. Disengage the tractor PTO.
2. Shut off the tractor engine, remove the ignition key and take it with you.
3. Wait for all movement to stop.
4. Remove the Telescoping PTO Drive and ALL power connections from the tractor.
ONLY when you have taken these precautions can you be sure it is safe to proceed. Failure to follow the above
procedure could lead to death or serious bodily injury.
BEFORE ATTEMPTING TO OPERATE YOUR NEW SPREADER BE SURE TO READ THIS OWNERS
MANUAL AND FAMILIARIZE YOURSELF WITH THE MACHINE!! OBSERVE THE PRECAUTIONS IN THIS
MANUAL FOR SAFE OPERATION OF THIS MACHINE!!
Most farm accidents, like industrial, home and highway accidents, are caused by the failure
of some individuals to observe simple and fundamental safety rules or precautions. For this
reason farm accidents, just as other types of accidents, can be prevented by recognizing the
causes of accidents and doing something about them before an accident occurs.
Regardless of the care used in the design and construction of farm equipment, there are
many points that cannot be completely safe-guarded without interfering with accessibility
and efficient operation.
A careful operator is the best insurance against an accident.
The complete observance of one simple rule would prevent thousands of serious injuries
each year. That rule is:
“NEVER ATTEMPT TO CLEAN, OIL, OR ADJUST A MACHINE WHILE IN MOTION”.
-NATIONAL SAFETY COUNCIL

PRESSURIZED HYDRAULIC FLUID AND EQUIPMENT SAFETY
•Only adequately trained and qualified persons should work on hydraulic systems. You may
be severely injured or killed by being crushed under a falling piece of equipment. Always
have transport locks in place and frame sufficiently blocked when working on any implement.
•Hydraulic fluid escaping under pressure can have sufficient force to cause injury. Keep all
hoses and connections in good service condition. Failure to heed may result in serious
personal injury or death. Escaping hydraulic fluid under pressure can have sufficient pressure
to penetrate the skin causing serious injury. Avoid the hazard by relieving pressure before
disconnecting any lines or performing work on the system.
•Make sure hydraulic fluid connections are tight and all hydraulic hoses and lines are in good
condition before applying pressure to the system. Use a piece of paper or cardboard, NOT
BODY PARTS, to check for suspected leaks. Wear protective gloves and safety glasses or
goggles when working with hydraulic systems. DO NOT DELAY! If an accident occurs, see a
doctor familiar with this type of injury immediately. Any fluid injected into the skin or eyes
must be treated within a few hours or infection may result.
•Always secure equipment with solid supports before working on or under it. Never work under
equipment supported by hydraulics. Hydraulics can drop equipment if controls are actuated,
hydraulic lines burst, or pressure is lost while disconnecting lines. Either situation can drop
machinery instantly even when power to hydraulics is off. Do not attempt to disconnect a
hydraulic cylinder or hose while the system is under pressure!
•Check hydraulic hoses and fittings frequently. Brush and other debris can damage hoses and
fittings. Inspect and maintain equipment daily. Loose, broken, and missing hardware can
cause equipment to not perform properly and can result in bodily injury or death.
•Hydraulic systems and oil can be hot and cause burns. Before working on any system, wait
until the oil has cooled.
•Keep body and extremities away from areas such as pivot points and hydraulic cylinders.
Always secure equipment pivot points to assure they will not move when working on or near
them.

PRE-OPERATION
GENERAL
Read the entire Owner’s Manual before attempting to operate this manure spreader. Before attempting any
maintenance or repairs; always be sure all rotating parts have stopped and that the tractor is shut off. Disconnect
the PTO, relieve all hydraulic pressure and disconnect hydraulic hoses.
WARNING
NEVER OPERATE SPREADER WITH ANY GUARDS OR SHIELDS REMOVED.
FAILURE TO HEED MAY RESULT IN SERIOUS PERSONAL UNJURY OR DEATH.
1. Completely lubricate the unit as described in the LUBRICATION Section.
2. Check and tighten the wheel lug nuts if required.
3. Check and maintain the tire pressure according to the manufacturer’s recommendation.
4. Check the entire unit for loose bolts, damaged or loose hydraulic fittings and hoses or other damaged parts.
5. The tractor half of the PTO drive shaft assembly must be locked securely to the tractor output shaft.
TRACTOR HITCH AND PTO REQUIREMENTS
•This spreader is designed to be operated by a 1000 RPM PTO Output. (540 RPM Optional).
•The spreader is designed to be towed by a CAT 3 drawbar with a Ø1-1/2” Pin Hole.
•The PTO drive shaft assembly is designed to operate with tractors conforming to the industry standard
shown on Figure 1. The telescoping driveline must have an 8” minimum sleeve overlap when connected.
ADMA Recommendations:
A tractor drawbar equipped with a clevis hitch (hammer-strap) can cause interference with the PTO driveline
IID (implement input driveline). This interference can cause serious damage to the IID or the IID telescoping
members. The clevis hitch on the tractor must be removed.
If the implement (figure 2, top view) is attached to a tractor with a clevis hitch (hammer-strap) style drawbar, the
hammer-strap must be removed to prevent damage to the IID guarding or the IID telescoping members.
If the implement (figure 2, lower view) is attached to a tractor with an offset in the drawbar, be certain it is in
the down position to prevent damage to the IID guarding or the IID telescoping members.

TRACTOR TOWING SIZE REQUIREMENTS
The spreader does not have brakes, towing the spreader must be done safely. The ASAE (American Society of
Agricultural Engineers) specifies that the towing vehicle should weigh at least 2/3 as much as the loaded
implement to be reasonably safe towing at speeds up to 20 mph. This (20 mph) is also the maximum
recommended towing speed for the spreader.
The loaded weight of your spreader will naturally vary with the moisture of the manure and you must consider that
for your conditions. The loaded weight as specified by the spreader manufacturer is as follows:
Use the following charts for calculating spreader gross weight and minimum tractor weight:
HYDRAULIC SYSTEM
There are two hydraulic circuits on the spreader:
1. One circuit powers the hydraulic end gate.
2. The second circuit powers the hydraulic apron drive. A check valve is installed in this circuit to prevent
operating the apron in reverse. Also, the hydraulic motor has a built-in relief valve that is preset.
Therefore, the tractor requires two sets of remote ports with a minimum recommended flow of 15 GPM.
The hydraulic system is rated for 3000 PSI. Tractor relief settings should not exceed 2500 PSI!
The spreader ships from the factory setup for closed center systems.

Open and Closed Center Hydraulic Systems
•Most late model tractors use a Closed Center hydraulic system with a variable displacement pump which
only pumps oil as required. This system is commonly CCLS (Closed Center Load Sensing), also known
as PFC (Pressure and Flow Compensated). The ball valve on the spreader should be closed.
•Other tractors may have an Open Center hydraulic system with a fixed displacement pump which pumps oil
continuously. This type of system typically does not have adjustable flow control from the tractor cab. The
Excess Flow (EF or EX) port on the spreader valve allows the excess flow to return to the tractor. The ball
valve on the spreader should be open.
•Check with your tractor dealer if you are not sure of which system you have equipped.
TRACTOR HOOKUP
1. Check that area is clear, SLOWLY back up tractor to spreader and line up draw pin holes.
2. Shift tractor to neutral or park and set the brakes.
3. Hook the spreader hitch to the tractor drawbar with Ø1-1/2” secured hitch pin.
4. Raise the jack off the ground. Remove the jack hub pin and rotate the jack to the horizontal position or move to
secondary storage location and secure with the pin.
5. Connect the PTO drive shaft to the tractor PTO output shaft and be sure it is locked to the tractor PTO shaft.
6. Connect the 7-Pin electrical plug for the lights to the receptacle on the tractor.
7. Run the “twist hose” (if equipped) for controlling apron speed to the tractor cab where it can be operated.
8. Connect the hydraulic hoses from the spreader to paired remote ports on the tractor.
Apron Drive –(2x) 8M3K Ø1/2” ID Hoses Hydraulic Gate –(2x) 6M3K Ø3/8” ID Hoses
NOTICE! The spreader apron circuit has a check valve so that the apron may not be operated in the wrong
direction. If the hoses are reversed, the apron will not operate and the hoses should be switched.
TRANSPORTING
GENERAL
While towing the spreader, check for traffic constantly. Be sure you can see that no one is attempting to pass you
and that all traffic is sufficiently clear from you before making any turns.
Operating speed is dictated by the terrain over which you are traveling. Always use caution. Avoid traveling on
slopes or hills that are unsafe. Also beware of slippery conditions such as traveling over areas previously spread
with manure. If possible, avoid spreading over areas where manure has been previously applied.
If you will travel on public roadways and it is legal to do so, you must know all rules governing such operation. This
will include lighting and brake requirements in addition to traffic rules. You may also be required to install a safety
chain on the spreader.
CAUTION
REGULARLY CLEAN OFF THE REFLECTIVE TAPE
AT THE REAR AND SIDES OF THE SPREADER
WHEN TRANSPORTING IT ON THE HIGHWAY.
WARNING
DO NOT TOW AT SPEEDS GREATER THAN 20
MPH. FAILURE TO HEED MAY RESULT IN
SERIOUS PERSONAL INJURY OR DEATH.

16 | P a g e M o d e l V B 2 8 0
Safety Chain Use
A safety chain should be installed when traveling on public roads. The chain must be strong enough to hold the
weight of the loaded spreader. If using a grab hook at the end(s) of the chain to secure the chain to itself, a hook
latch must be installed. The length of the safety chain is not to be any longer than necessary to turn without
interference. If any chain links or attachment hardware are broken or stretched, repair before using. Store chain
so it does not corrode or become damaged. Do not use this chain for other implements because the strength and
length of chain may not be adequate. Identify this chain for use on this particular spreader.
CAUTION
A SAFETY CHAIN SHOULD BE INSTALLED TO
RETAIN THE CONNECTION BETWEEN
TRACTOR (OR OTHER TOWING VEHICLE)
AND SPREADER WHENEVER TRAVELING ON
PUBLIC ROADS. A SUGGESTED
ATTACHMENT IS ILLUSTRATED. FIGURE 4.
Highway Lights
The spreader comes standard with highway lights. Lights are recommended for any spreader operated on public
roadways and may be required by law. Be sure to plug the electrical plug into the tractor receptacle when hooking
up the spreader. Clean lights as needed to maintain visibility!
If your tractor does not have a receptacle for the electrical plug, then a SMV (Slow Moving Vehicle) sign must be
installed at the rear of the spreader.
NOTICE! The 7-Pin Plug is wired for separate turn and brake signals. Some vehicles may use the same wire for
turn and brake signals. In this case, the brake function will use the amber lights instead of the red lights. If towing
behind a vehicle with this wiring setup, a converter should be used to separate the turn and brake signals.

OPERATION
DANGER
NEVER ENTER THE SPREADER BOX FOR ANY
REASON WITHOUT FIRST DISCONNECTING
PTO SHAFT FROM TRACTOR. DO NOT ALLOW
OTHERS IN THE BOX. ROTATING BEATERS
CAN DISMEMBER OR KILL.
CAUTION
DO NOT USE JACK EXCEPT WHEN SPREADER
IS EMPTY. JACK WILL NOT SUPPORT ADDED
WEIGHT FROM LOAD. UNBALANCED WEIGHT
MAY RESULT IN UNEXPECTED “TIP UP” OF
THE SPREADER.
LOADING
1. Check that the hydraulic end gate is closed, Figure 5.
2. Park spreader for loading, shift the tractor to neutral or park and set the brakes.
3. Load manure into spreader EVENLY. Loading manure unevenly may cause tip-up or excessive hitch weight.
4. Approach spreader slowly and take care while maneuvering. Do not collide the bucket or loader with spreader.
5. Solid manure may be loaded at least level with the top of the box while semi liquid and liquid slurries will have
to be less than full in the spreader box. It is unlawful to allow slurry to splash or leak onto public roads!
WARNING
BE SAFE WHEN LOADING! IF LOADING WITH A SKID STEER,
CARRY LOADS LOW UNTIL YOU REACH THE SPREADER.
APPROACH SPREADER SLOWLY. EXCESSIVE SPEED AND / OR
SUDDEN STOPS MAY CAUSE SKID STEER TO TIP OVER!

UNLOADING
The rear beaters have been designed and tested to provide the best spread pattern for most liquids and semi-
solid manure. However, the pattern will vary for each specific condition. The factors that contribute most to
differing patterns will be moisture content and the amount and length of bedding material. For most typical
conditions, the spread pattern should be uniform and about 30 ft wide or more. Plan your spreading patterns so
you do not have to travel over previously spread manure which will be slippery, resulting in poor traction. Traction
on wet grass is also poor. When the resulting pattern may require that you overlap during spreading, use
precautions on slopes and hills where you will experience a loss of traction by traveling over ground with
previously spread manure.
DANGER
KEEP AWAY AND KEEP OTHERS CLEAR OF
ROTATING BEATERS AT REAR OF
SPREADER. SERIOUS INJURY OR
AMPUTATION COULD RESULT.
WARNING
MAKE CERTAIN EVERYONE IS CLEAR OF
EQUIPMENT BEFORE APPLYING POWER.
FAILURE TO HEED MAY RESULT IN SERIOUS
PERSONAL INJURY OR DEATH.
CAUTION
DO NOT OPERATE APRON CHAIN WITHOUT
RAISING END GATE FIRST. FAILURE TO HEED
MAY RESULT IN EQUIPMENT DAMAGE.
WARNING
DO NOT OPERATE SPREADER WITH ANY GUARD
OPEN OR MISSING. ROTATING PARTS CAN
DISMEMBER OR KILL.
When you are ready to begin spreading application on the field:
1. Slowly engage the tractor PTO clutch and increase RPM to proper PTO operating speed. DO NOT engage the
PTO at operating speed!
2. Open the hydraulic end gate to the desired height by applying the tractor hydraulic lever. This can be done
while traveling forward to avoid a heavier application at the edge of the field than desired.
3. Once the end gate is open and the PTO is up to speed, engage the hydraulic apron.
See page 18 for detailed operation of your spreader’s hydraulic apron.
4. For solid manure, start the apron at a slow rate of speed.
5. Start application onto the field. Increase the speed of apron chain for a heavier application.
NOTICE! Do not feed frozen manure at a rate too fast. The apron drive may feed faster than the
beaters can expel the material. When frozen chunks are present, reduce apron speed to
approximately 1/3, to allow the beaters time to grind the chunks into small pieces.
6. Further control of the application rate is possible by the relationship of tractor engine speed to ground speed
(transmission gear selection). For optimum trouble free performance it is recommended to operate at or near
engine PTO speed.
7. When the spreader is empty, stop the PTO. A clattering noise may be heard coming from the over-running
clutch, this is normal as the beaters coast to a stop.
8. Stop the apron chain, then close the end gate.

MANDATORY SAFETY SHUTDOWN PROCEDURE
BEFORE unclogging, cleaning, adjusting, lubricating or servicing the unit:
1. Disengage the tractor PTO.
2. Shut off the tractor engine, remove the ignition key and take it with you.
3. Wait for all movement to stop.
4. Remove the Telescoping PTO Drive and ALL power connections from the tractor.
ONLY when you have taken these precautions can you be sure it is safe to proceed.
Failure to follow the above procedure could lead to death or serious bodily injury.
Hydraulic Apron, Speed Control Options
Standard Flow Control: The standard system utilizes the tractor’s flow control. This system requires that the
tractor have an adjustable flow control lever or knob. There is no adjustable flow control
valve on the spreader with this option.
Manual Flow Control: The manual flow control option has an adjustable flow control valve on the spreader.
Flow is adjusted by twisting the “control hose” from the tractor cab. The tractor end of
this hose is fitted with a handle. Turn CW to increase flow, turn CCW to decrease flow,
referencing the speed indicator at the front of the spreader. Use the set screw on the
valve to adjust tension or retain settings.
Electric Flow Control: The electric flow control option has an electro-proportional valve on the spreader. Flow is
adjusted using the control box from the tractor cab. Plug control box into a 12 VDC power
source, flip switch to “ON”, and use the rate control knob to adjust hydraulic flow. The
valve is normally closed, and requires power to open. The valve is equipped with a
manual override in case of electrical issues. To manually open the valve, remove the
acorn nut located on the valve, and turn the override screw in.
UNHOOKING FROM TRACTOR
1. Park the spreader, set tractor parking brake, and turn off all power.
2. Park your spreader on level ground and place blocks ahead of and behind the wheels.
3. Remove jack pin and move to vertical position, raise jack until hitch is not resting on tractor drawbar.
4. DO NOT UNHITCH A LOADED SPREADER LEAVING IT SUPPORTED BY ONLY THE JACK!
5. Disconnect the PTO shaft, hydraulic hoses, electrical plug, and safety chain. Remove pin.

The wheel studs should be torqued to 297 foot pounds in a crisscross pattern.
TIRE PRESSURES: 425-65R Recommended Pressure: 65 PSI
1600R20 Recommended Pressure: 75 PSI
19L x 16.1 Recommended Pressure: 25 PSI
600/55 x 26.5 Recommended Pressure: 50 PSI
Wheel Hub Lubrication
Remove the wheels and hubs annually. Clean out old grease and repack bearing cones with quality EP grease.
Put a ¼” film of grease on the bearing cups and reassemble. If your hubs have grease zerks, do not lube them.
Grease builds up in the hub and will eventually damage the seal when expansion from heat occurs.
Lock Ring Rim
Removing, replacing and repairing industrial tires and rims with lock rings can be dangerous without proper tools,
equipment and training to perform this service. It is recommended that this work be performed only by a qualified
tire repair shop.
WARNING
NEVER INFLATE BEYOND RIM OR TIRE
MANUFACTURER’S APPROVED PSI RATING.
WHILE INFLATING, STAY OUT OF THE
TRAJECTORY & STAND CLEAR OF TIRE/WHEEL
ASSEMBLY. A TIRE BLOW OUT OR RIM/WHEEL
FAILURE CAN CAUSE SERIOUS INJURY OR
DEATH.
DANGER
IF THE LOCK RING SHOULD BLOW OFF, IT AND
OTHER PARTS COULD FLY OFF WITH ENOUGH
FORCE TO INJURE OR KILL A PERSON. NEVER
STAND IN THE POTENTIAL BLOW OUT AREA
AND KEEP OTHERS AWAY.
AUTOMATIC CLUTCH
In the event that the beater drive becomes overloaded (such as with a clog), the clutch on the rear drive assembly
will automatically disengage, causing loss of power to the beaters and an audible clattering noise.
If this happens, perform the following:
1. Immediately stop hydraulic flow to the apron. Disengage the PTO and allow it to coast down. The
clutch will re-engage at a slow speed if the overload has cleared.
2. AT SLOW SPEED, re-engage the tractor PTO and allow the beaters to run freely. Increase RPM,
restart hydraulic flow to the apron, and resume operation.
3. If the clutch will not re-engage, then the beaters are still over loaded or plugged. It will be necessary
to manually unplug the beaters to remove the clog. PERFORM SAFETY SHUTDOWN PROCEDURE!! A
foreign object such as a rock may be found to be the cause of over load.
4. Once the clog has been cleared, return to step 2.
