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. Driving the belt toward the rear of the spreader
pulls the sliding gate rearward to move the load toward the beaters. 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. This gate must be lowered during loading to prevent packing of the material into
the beaters and to help prevent leakage during transport.

the warning horn to sound.
Start with a slow rate and then increase as
required. Once adjusted, the unloading rate will
remain constant for the same type of material.
Further application rate adjustment can be obtained
by regulating the tractor ground speed. The
application 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
hydraulic 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.
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
familiar with this operation.
Sliding Gate
The unloading belt which moves the sliding gate is
powered by a hydraulic motor and planetary
gearbox. 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 Operator is
familiar with this operation.
NOTE: Set the tractor hydraulic selective control
valve to 8 - 12 gallons per minute. To much
hydraulic flow will cause the floor belt and sliding
gate to stop and not move, to little flow will cause
the belt and sliding gate to move to slowly.
When the sliding gate reaches the rear of the
spreader it will bear against mechanical 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
remote adjusted flow control valve in the tractor.
See figure 1.
The remote flow control knob is turned CW to
increase the rate and CCW to decrease the rate.
Completely CCW is OFF.
NOTE: If the belt speed is too fast the material will
overload the beaters and cause them to stall and

TRACTOR DRAWBAR
Set tractor drawbar as shown in figure 2.
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
Spreader should be approximately level when
attached to tractor.
Trailer hitch has 4 positions.
FAILURE TO SET DRAWBAR
PROPERLY MAY CAUSE SHAFT TO OVER
EXTEND AND SEPARATE OR BEND WHEN
CORNERING OR TRANSPORTING RESULTING
IN DEATH OR PERSONAL INJURY.
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 450
FT/LBS, dry threads.
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 must be open
prior to engaging PTO (handle parallel with
valve housing).
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.

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 & MARKING
Hazard lights are standard equipment on the
spreader, When towing on roads extend the hazard
light brackets to the out position.
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.
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 a slow
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

storage bracket and connect the ends to a
tractor port. See Understand The Controls on
page 12 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 to a tractor port. See Understand The
Controls on page 12 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.
LOADING
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.
TRACTOR HOOKUP
See figure 4.
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

UNLOADING
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, begin forward motion.
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 enough to
clear the rear gate, 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.

ADJUSTING, LUBRICATING, OR SERVICING
THIS MACHINE.
1. The spreader must be thoroughly cleaned
periodically, especially if stored for extended
periods. 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.
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.
TURN OFF ALL POWER
DURING CLEANING AND INSPECTION. DO NOT
USE POWER TO MOVE ANY COMPONENTS OR
TO DISCHARGE MATERIAL WHILE CLEANING OR
INSPECTING.

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 should always be disconnected if
the spreader is not disconnected from the
towing vehicle.
LUBRICATION
Bearings
Grease 2 lower beater bearings and 2 belt pulley
bearings every 100 hours of operation with 2
pumps of grease. See figure 6.
PTO DRIVE SHAFT
1. The PTO drive shaft yoke cross bearings must
be greased, both ends of assembly. Grease
every 8 hrs of operation with one pump. See
figure 6.
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. See
figure 6.
PUT THE TRACTOR IN PARK, APPLY THE PARKING BRAKE, TURN OFF ENGINE
AND REMOVE IGNITION KEY BEFORE CLEANING, ADJUSTING, LUBRICATING OR SERVICING THIS
MACHINE. FAILURE TO HEED MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
MAINTENANCE
DISCONNECT PTO DRIVE SHAFT AND HYDRAULIC HOSES BEFORE CLEANING,
ADJUSTING, LUBRICATING, OR SERVICING THIS MACHINE.

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.
