PRINCIPLE OF OPERATION
Two vertical spinning beaters at the rear of the spreader expel manure in a uniform spread pattern. Each beater is
driven by a hydraulic motor. A PTO driven hydraulic power supply on the spreader provides power to the beaters.
The hydraulic pump is two stage thereby supplying independent power to each beater motor.
A wide heavy duty belt covers the box floor. At the front of the spreader, this belt is attached to a sliding gate. At
the rear, this belt goes around a winged idler pulley and on the lower side is connected to a drive chain. At the
front of the spreader, this chain is driven by a hydraulic motor driving a planetary gear box and sprocket that is
powered by the tractor hydraulic system. See figure 1 page 19. Driving the belt toward the rear of the spreader
pulls the sliding gate rearward to move the load toward the beaters. A remote flow control in the tractor cab or
a manually adjustable flow control in the drive chain motor circuit regulates the speed the gate moves.
An end gate at the rear of the spreader is raised and lowered by two hydraulic cylinders, powered by the tractor
hydraulic system. See figure 5page 17. This gate must be lowered during loading to prevent packing of the material into
the beaters and to help prevent leakage during transport.

PRE OPERATION
UNDERSTAND THE CONTROLS
Rear Gate
The rear gate cylinders are hydraulically controlled
by a tractor spool valve. It is recommended that the
hoses be connected to the tractor so pulling the
spool valve lever back raises the gate and pushing
the valve lever forward closes it. Make it a habit to
connect the hoses the same so the Operator is fa-
miliar with this operation.
Sliding Gate
The unloading belt which moves the sliding gate is
powered by a hydraulic motor and planetary gear-
box. This motor is powered from the tractor
hydraulic system and started and stopped by the
tractor spool valve for the port to which this motor
is connected. It is recommended that the hoses
be connected to the tractor so pulling the spool
valve lever back starts the gate rearward and
pushing the valve lever forward returns the gate to
the front. The gate can be stopped by moving the
spool valve lever to the neutral detent. Make it a
habit to connect the hoses the same so the Opera-
tor is familiar with this operation.
When the sliding gate reaches the rear of the
spreader (see figure 5) it will bear against me-
chanical stops. The tractor hydraulic system will
sense increased hydraulic pressure and return the
spool valve to the neutral OFF position. The same
process occurs when returning the gate to the
front.
Rate Of Application
The rate of application is determined by how fast
the sliding gate and belt (floor) progresses toward
the rear of the spreader. This is regulated by a
manually adjusted flow control valve on the
spreader or a remote adjusted flow control valve in
the tractor. See figure 1.
The remote flow control knob is turned CW to in-
crease the rate and CCW to decrease the rate.
Completely CCW is OFF.
The manual flow control knob should be turned
CW to decrease the rate and CCW to increase the
rate. Completely CW is OFF.
NOTE: If the belt speed is too fast the material will
overload the beaters and cause them to stall and
the warning horn to sound.
Always turn power off when making this adjust-
ment. Start with a slow rate and then increase as
required. Once adjusted, the unloading rate will
remain constant for the same type of material. Fur-
ther application rate adjustment can be obtained
by regulating the tractor ground speed. The appli-
cation rate is not affected by engine RPM.
Spread Pattern
The spread pattern is affected by the speed of the
rotating beaters. The two beater hydraulic motors
are powered independently by a two stage hydrau-
lic pump on the spreader. This pump is powered
by the tractor PTO. The spreader is designed to
give a uniform spread pattern when the tractor
engine is operated at 1000 PTO RPM for typical
materials. Adjustment of the beater speed and
spread pattern is regulated by the engine speed.
TRACTOR DRAWBAR
Set tractor drawbar as shown in figure 2.
FAILURE TO SET DRAWBAR PROPERLY MAY
CAUSE SHAFT TO OVER EXTEND AND SEPA-
RATE OR BEND WHEN CORNERING OR
TRANSPORTING RESULTING IN DEATH OR
PERSONAL INJURY.
Spreaders are available for 1000 RPM drive line
only. Match tractor PTO with the spreader drive
line.

IMPORTANT: To prevent drive line damage,
adjust tractor drawbar to recommended setting.
Disengage tractor PTO before turning.
Adjust Trailer Hitch Clevis
Spreader should be approximately level when
attached to tractor.
Adjust clevis by changing hole location on trailer
tongue.
PRE OPERATION CHECKLIST
1. Carefully study and understand this manual.
2. Do not wear loose-fitting clothing, which may
catch in moving parts.
3. Always wear protective clothing and substantial
shoes.
4. Keep wheel lug nuts or bolts tightened to
specified torque.
5. Assure that agricultural implement tires are
inflated evenly and at proper pressure.
6. Give the unit a visual inspection for any loose
bolts, worn parts or cracked welds, and make
necessary repairs. Follow the maintenance safety
instructions included in this manual.
7. Check to see that no obstructions are present in
the spreader prior to start up.
8. Be sure that there are no tools lying on or in the
spreader.
9. Do not use the unit until you are sure that the
area is clear, especially children and animals.
10. The ball valve in the suction line and the return
line must be open prior to engaging PTO (handle
parallel with valve housing). (See Page 42
RESEROIR TANK)
11. Because it is possible that this spreader may be
used in dry areas or the presence of
combustibles, special precautions should be
taken to prevent fires and fire fighting equipment
should be readily available.
12. Don’t hurry the learning process or take the unit
for granted. Ease into it and become familiar with
your new spreader.
13. Practice operation of your spreader and its
attachments. Completely familiarize yourself and
other operators with its operation before using.
14. Securely attach to towing unit. Use a high
strength, appropriately sized hitch pin with a
mechanical retainer.
15. Do not allow anyone to stand between the tongue
or hitch and the towing vehicle when backing up
to the spreader.
HIGHWAY AND TRANSPORT
OPERATION
1. Adopt safe driving practices:
2. Always drive at a safe speed relative to local
conditions and ensure that your speed is low
enough for an emergency stop to be safe and
secure. Keep speed to a minimum.
3. Reduce speed prior to turns to avoid the risk of
overturning.
4. Avoid sudden uphill turns on steep slopes.
5. Always keep the tractor in gear to provide engine
braking when going downhill. Do not coast.
6. Do not drink and drive.
7. Comply with state and local laws governing
highway safety and movement of farm machinery
on public roads.
8. Use approved accessory lighting, flags and
necessary warning devices to protect operators of
other vehicles on the highway during daylight and
night time transport.
9. The use of flashing amber lights is acceptable in
most localities. However, some localities prohibit
their use. Local laws should be checked for all
highway lighting and marking requirements.
FIGURE 2. TRACTOR DRAWBAR

10. 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.
11. When driving the tractor and spreader on the
road or highway at night or during the day, use
flashing amber warning lights and aslow moving
vehicle (SMV) identification emblem.
12. Be sure the slow moving vehicle sign is installed
on the rear of the spreader for transporting on
roadways.
13. Plan your route to avoid heavy traffic.
14. Be a safe courteous driver. Always yield to
oncoming traffic in all situations, including narrow
bridges, intersections, etc.
15. Be observant of bridge loading ratings. Do not
cross bridges rated lower than the gross weight
at which you are operating.
16. Watch for obstructions overhead and to the side
while transporting.
17. Make allowances for increased length and weight
of the spreader when making turns, stopping the
unit, etc.
18. Install safety chains as illustrated on figure 3.
This is a requirement for travel on public
roadways. They are installed to retain the
connection between tractor (or other towing
vehicle) and spreader whenever traveling on
public roads.
Lighting and Marking
It is the responsibility of the customer to know the light-
ing and marking requirements of the local highway au-
thorities and to install and maintain the equipment to
provide compliance with the regulations. Add extra
lights when transporting at night or during periods of
limited visibility.

1. Back tractor so draw bar aligns with spreader
hitch. Put tractor in PARK, set park brake and
turn off engine before dismounting.
2. Connect the spreader hitch to the tractor drawbar
with a 1-1/4” hitch pin. The hitch pin must have a
security clip or retainer to prevent it from
accidentally coming out of the hitch.
3. Install safety chain around tractor drawbar
support and secure with safety latched grab
hook. See figure 3.
4. Crank the spreader jack completely up.
5. Remove the pair of hydraulic hoses coming from
the spreader hydraulic pump from their storage
bracket and connect the ends a tractor port. See
Understand The Controls on page 13 for
recommended connection.
6. Remove the pair of hydraulic hoses coming from
the spreader rear gate hydraulic cylinders from
their storage bracket and connect the ends a
tractor port. See Understand The Controls on
page 13 for recommended connection.
7. Unhook the PTO storage chain from the slotted
storage bracket and slide the PTO drive shaft
yoke onto the splined tractor PTO shaft. Be sure
the yoke securely snaps onto the retention
groove of the tractor shaft.
8. Connect the PTO Guard anchor chain to the
anchor loop on the spreader hitch.
9. Place the PTO storage chain back in the slotted
storage bracket so it does not dangle.
10. Remove wheel chocks.
NEVER OPERATE SPREADER
WITH ANY GUARDS OR SHIELDS REMOVED. FAIL-
URE TO HEED MAY RESULT IN SERIOUS PER-
SONAL INJURY OR DEATH.
LOADING
SPREADER MUST BE HITCHED
TO TRACTOR FOR LOADING. THE JACK CAN NOT
SUPPORT THE LOADED SPREADER WEIGHT
AND/OR UNEXPECTED “TIP UP” OF THE
SPREADER CAN RESULT.
1. Park the spreader for loading. Put the tractor in
PARK or NEUTRAL and apply the parking brake.
2. Close the hydraulic rear gate before loading.
3. It is unlawful to allow any manure spillage to
occur on public roadways. Be sure rear gate is
fully closed and sliding gate scrapers are
adjusted so no liquid leakage occurs. Do not
heap load such that manure is allowed to fall off
spreader during transporting on roadways.
4. Load the spreader. The moisture content will
determine how full it can be loaded. See
SPECIFICATIONS for capacity. Solid manure
can generally be loaded level to slightly heaped.
High moisture slurries are heavier and loading
may be limited.

BEATERS CAN CRUSH, DISMEMBER OR KILL.
CLEAR THE AREA OF ALL
PERSONS BEFORE BEGINNING OPERATION.
1. Engage the tractor PTO to start the beaters and
increase engine speed to 1000 PTO RPM.
2. Raise the hydraulic rear gate completely up. See
figure 5.
3. Start the sliding gate.
4. When material begins discharging from the
beaters and the spreading light comes on begin
forward motion.
NOTE: Performing the preceding steps while moving
forward will minimize heavy discharge onto the field
during startup.
5. Plan application onto the field so that you do not
travel over previously spread manure which is
slippery. Travel cautiously on hills and slopes.
Proceed up and down slopes instead of along
them.
SHUT DOWN
1. When the load has been discharged, the
hydraulic control to the sliding gate will return to
neutral, OFF. Allow the beaters to operate for a
few seconds to clear out any remaining material
and then stop the PTO.
2. Start the sliding gate to return to the front of the
spreader. When it reaches the front the hydraulic
control to the sliding gate will return to neutral,
OFF.
3. Once the sliding gate moves forward to the stop
position, completely close the rear gate.
UNHOOK THE TRACTOR
1. Park the spreader on level ground. Put the tractor
in PARK, set the park brake, and turn the engine
off before dismounting.
2. Place wheel chocks in front and in back of two
spreader wheels on opposite sides to prevent the
spreader from rolling after the tractor is
unhooked.
3. Remove the PTO drive shaft yoke from the
splined tractor PTO shaft. Unhook the PTO
storage chain from the slotted storage bracket
and pivot the PTO drive shaft up and into the
storage bracket. Reconnect the storage chain in
the slotted storage bracket to secure the PTO
shaft.
4. Remove the hydraulic hose ends from the tractor
hydraulic ports and store the hose ends in the
slotted hose storage brackets to keep them from
dragging on the ground. See figure 4.
5. Crank the spreader jack down until the spreader
hitch lifts off the tractor draw bar.
6. Remove the hitch pin.
7. Unhook safety chain from tractor drawbar
support. See figure 4.
8. Slowly drive the tractor away from the spreader.
STORAGE AND CLEANING
DISCONNECT PTO DRIVE SHAFT AND
HYDRAULIC HOSES BEFORE CLEANING,
ADJUSTING, LUBRICATING, OR SERVICING THIS
MACHINE.
1. The spreader must be thoroughly cleaned for
extended storage. Manure is acidic and will
damage paint and cause rusting of metal
components.

2. Allow the spreader to completely unload.
3. Return the sliding gate to the front of the
spreader.
4. To clean the spreader, raise the rear gate.
TURN OFF ALL POWER DURING
CLEANING AND INSPECTION. DO NOT USE
POWER TO MOVE ANY COMPONENTS OR TO DIS-
CHARGE MATERIAL WHILE CLEANING OR IN-
SPECTING.
5. Hose off manure from the outside and inside of
the spreader. Completely clean manure from
moving mechanisms such as the beaters, winged
pulley, sliding gate, chain drive and rear gate.
Remove accumulation in confined areas or
pockets that trap manure.
6. Avoid directing high pressure spray directly on
bearings, seals and flow control valve.
7. Keep high pressure spray moving on painted
surfaces. Sustained spray on cracks or scratches
in paint can result in paint peeling.
8. Allow machine to dry.
9. Lower rear gate completely down before storing
spreader.
10. Inspect the spreader for loose connections,
damaged hydraulic hoses or connections and for
other damaged components. Repair if necessary
so the spreader is ready for future operation.

MAINTENANCE
PUT THE TRACTOR IN PARK, APPLY THE PARKING BRAKE, TURN OFF ENGINE AND
REMOVE IGNITION KEY BEFORE CLEANING, ADJUSTING, LUBRICATING OR SERVICING THIS MA-
CHINE. FAILURE TO HEED MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
READ THE FOLLOWING BEFORE
WELDING ON THIS MACHINE
1. When welding on your spreader, do not allow the
current to flow through the ball bearings or the
roller chains. Ground directly to the item being
welded.
2. The alternator shouwwld always be disconnected
if the spreader is not disconnected from the tow-
ing vehicle.
LUBRICATION
Bearings
Grease 2 lower beater bearings and 2 wing pulley
bearings every 100 hours of operation with 2 pumps of
grease. See figure 6.
PTO Drive
1. The PTO drive shaft yoke cross bearings must be
greased, both ends of assembly. Grease every 8
hrs of operation with one pump.
2. There is also a zerk at the center of the shaft
assembly to grease the telescoping shafts. It is
accessible through a slot in the guard. Grease
every 8 hrs of operation with 4 pumps.
Drive Chain Planetary Gearbox
(See figure 7)
Oil Specification: Mobil Delvac Synthetic Gear Oil
75W-90.
There is a check plug half way up on the gearbox.
Maintain the oil level to this check plug. Fill plug is lo-
cated on the top of the gearbox.
DISCONNECT PTO DRIVE SHAFT AND HYDRAULIC HOSES BEFORE CLEANING, AD-
JUSTING, LUBRICATING, OR SERVICING THIS MACHINE.

HYDRAULIC SYSTEM
(See figure 8)
1. Oil Specification: CITGO Transgard Tractor
Hydraulic Fluid - Material Code 633310001
2. Capacity: 40 gallon
3. Maximum allowable operating temperature
240_F.
4. Check the oil level in the reservoir daily. It should
be maintained 1” from the top level on the sight
gauge.
5. Oil is added through a filter screen inside the filler
neck. Before filling, remove the screen, inspect
and clean if required.
6. Carefully clean dirt from the return filter head and
element. Replace the filter element every 500 hrs
of operation.
7. Drain reservoir and refill with new oil every 2000
hrs or annually, whichever occurs first. If the oil
becomes contaminated and appears milky
colored, replace immediately.
8. Every 100 hrs of operation, inspect all hydraulic
hoses, hose connections, pump seals and motor
seals for leakage. Tighten loose connections and
replace damaged components.
9. A ball valve is provided at the bottom of the
reservoir where the suction hose is connected.
Turn this valve off to service hydraulic
components. This prevents draining of the
reservoir, however it is necessary to catch the oil
that drains from disconnected hoses into a
suitable container for proper disposal. Always
check and refill the reservoir as required when
servicing is completed.
Rear Gate Flashing
(See figure 9)
1. Swinging gate flashing strips are clamped to both
vertical ends of the rear gate frame. These strips
must bear against the vertical box sides to
minimize leakage.
2. To adjust, loosen the six 3/8" carriage bolts
clamping the flashing.
3. Move the flashing strips so they contact against
the box wall and retighten bolts.
