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

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 540 RPM PTO Output. (540 RPM Standard / 1000 RPM Optional).
The PTO drive shaft assembly is designed to operate with tractors conforming to the industry standard
shown on Figure 1. The telescoping PTO driveline must have a 5” 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.
Therefore, the tractor requires two sets of remote ports with a minimum recommended flow of 12 GPM.
The spreader comes standard with a Manual Flow Control system for operating the apron. The system has an
adjustable flow control valve on the spreader which is manually controlled by twisting the “control hose.”
The hose is connected to the flow control valve on the spreader and the opposite end of the hose is fitted with a
handle to operate from the tractor seat. The flow control lever on the spreader has a tension screw adjustment to
regulate force to retain settings. See Figure 3 on Page 14.

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).
•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.
Spreader Setup
See Figure 3.
•The spreader, with its standard Manual Flow Control
system, may be used for all types of hydraulic
systems by opening or closing the ball valve located
on the return port of the adjustable flow control valve.
•If your tractor does not have adjustable flow control,
the ball valve must be open, allowing excess flow to
return to the tractor. Apron speed should be regulated
using the equipped “twist hose”.
•If your tractor has adjustable flow control, the ball
valve should be closed. You may move the flow
control valve to max speed and use the tension screw
to lock it in place. You may also opt to remove the
“twist hose” as hydraulic flow / apron speed can
already be adjusted from the tractor.
•A secondary flow control valve on the spreader
regulates apron speed and limits the flow to 7.5 GPM.
Excess flow is returned to the tractor.
TRACTOR HOOKUP
1. 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 1 3/8” 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 electrical plug for the lights to a receptacle on the tractor.
7. Run the “twist hose” 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 in it 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.
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.
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.

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 BEATER
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 or splash to 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 the width of the spreader. 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.
2. Open the hydraulic end gate, Figure 7, 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.
•For manual flow control systems, regulate apron speed using the “twist hose” control. Turn handle CW to
increase apron speed or CCW to decrease.
•For tractor operated flow control, the flow control on the spreader should be set to max speed. Adjust apron
speed using tractor lever or other controls.
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. WARNING
AS THE SPREADER NEARS EMPTY, DEBRIS THAT IS NORMALLY
BLOCKED BY THE LOAD MAY FLY FORWARD TOWARD THE TRACTOR.
LOWER HYDRAULIC END GATE AS NEEDED TO BLOCK DEBRIS FROM
BEING THROWN FORWARD. FAILURE TO HEED MAY RESULT IN SERIOUS
PERSONAL INJURY OR DEATH.
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 so there is no chain slat under the hydraulic end gate, then close the end gate.

18 | P a g e M o d e l M 3 2 8 0
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.
MAINTENANCE, ADJUSTMENTS, & LUBRICATION
WHEEL & TIRE MAINTENANCE
WHEELS: Check after first hour of towing and periodically thereafter. The wheel studs should be torqued to 170
foot pounds in a crisscross pattern.
TIRE PRESSURE: 425-65R Recommended Pressure: 45 - 90 PSI MAX
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.
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.

M o d e l M 3 2 8 0 19 | P a g e
CLEANING AND STORAGE
Before storing this spreader for an extended period of time, perform the following:
1. Allow the spreader to completely clean out the last load.
2. Thoroughly hose off all manure from the outside of the spreader and the inside of the box, particularly getting
the end gate mechanism clean. The water can be drained into your manure storage pit or if the gate is left
closed, the water can be taken to the field and spread.
3. If pressure washing spreader, be careful not to wash directly on or too close to any bearing seals. The high
pressure can destroy the seal and force water into the bearing causing it to rust and fail. Avoid pressure
washing painted areas of the spreader too closely as the pressure can strip paint on scratched areas.
4. Manure is very acidic and should not be left on painted areas for a long period of time because it will lift paint
from the metal. Unpainted metal will corrode causing holes to rust through metal guards or even fall off the
machine. If this should happen, guards must be replaced immediately.
5. After cleaning, lube the spreader to exclude moisture from bearings and prevent condensation from forming
during storage.
6. Inspect all elements and check for parts that need repair or replacement. Performing these tasks now will
guarantee that the spreader is ready for use at the beginning of the next season.

ADJUSTMENTS
Apron Chain
A1. The apron chain is adjusted by (4) adjuster screws located on the front of the box frame. Adjust the
screws until the chain is sagging approximately 5” below the frame at the chain’s lowest point. When
there is no more adjustment left on the adjuster screws, loosen the nuts on the screws and push the
screws in as far as they will go. Then remove a link from each chain and readjust the apron chain.
NOTICE! Tightener screws need to be adjusted equally in order for chain to run centered on front rollers.
Roller Chains
A2. The main beater drive chain is tensioned by a spring-loaded idler. Periodically check tension.
Spring should be stretched approximately 1-1/2” to 2” (9-1/2” – 10” Total Length).
Adjust anchor bolt if more tension is needed. Check that the tensioner arm is able to move freely.
A3. The upper beater drive chain is tensioned by a spring-loaded idler. Periodically check tension.
Spring should be stretched approximately 1-1/2” to 2” (6-1/2” – 7” Total Length).
Adjust anchor bolt if more tension is needed. Check that the tensioner arm is able to move freely.
Front V-Belt Drive
A4. -Check front V-Belt tension frequently during first 24-48 hours of operation and periodically thereafter.
The belt is automatically tensioned by a spring loaded idler. Check that arm is able to move freely.
Spring should be stretched approximately 1-1/2” to 2” (9-1/2” – 10” Total Length).
-Inspect and clean belt of foreign material which may cause slippage. Never apply belt dressing as this will
damage the belt and cause early failure.
LUBRICATION
NOTICE! Spreader must be sitting level for an accurate oil check. To check oil levels, park spreader on level
ground and use jack to raise / lower the spreader until it is completely level.
L1. Maintain oil level and quality in apron drive gear reducer at the check level plug / sight glass.
When required, drain and refill with SAE 85-140 EP gear lube or Synthetic SAE 75-90 gear lube. (5.7 qt.)
L2. Maintain oil level and quality in beater drive gear box at the check level plug / sight glass.
When required, drain and refill with SAE 85W-140 Synthetic gear lube. (1.4 qt. / 45 fl. oz.)
L3. Grease front input shaft bearings. 2 locations: LH side of Input Shaft / PTO shield. 1 pump every 8 hours.
L4. Grease side shaft bearings. 6 locations: 1 in Front Drive Case, 5 along RH side. 1 pump every 8 hours.
L5. Grease apron shaft bearings. 3 locations: 1 at each end of apron shaft on outer bearing housings.
Center bearing by remote grease line on LH side of spreader. 1 pump every 8 hours.
L6. Grease beater shaft bearings. 4 locations: 1 at each end of both the top and bottom beaters.
L7. Oil roller chains with light weight machine oil. Oil should be applied every 8 hours or as often as necessary
to prevent the bearing area of the chain from becoming dry.
L8. Grease Axle Shafts. 2 locations on each side of spreader by remote lines. 10 pumps every 8 hours.
L9. Grease Gate Pivot Bolts. 1 on each side of spreader. 2 pumps every 8 hours.
L10. Grease the Over-Running Clutch by slot on LH Side of Input Shaft / PTO Shield. 3-4 pumps every 8 hours.
