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

M o d e l M S 4 85 15 | P a g e
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. NO PTO ADAPTERS MAY BE USED.
•The spreader is designed to be towed by a CAT 3 drawbar with a Ø1-1/2” Pin Hole.
Ø2” Pins may be used with the articulating hitch option (with Ø1-1/2” insert removed).
•The front PTO driveline assembly is equipped with an 80° Constant Velocity Joint.
DO NOT EXCEED THE MAXIMUM 80° TURNING ANGLE
•The PTO drive shaft assembly is designed to operate with tractors conforming to the
standards shown on Figure 1.
•Test PTO travel by turning tractor in both directions. The telescoping driveline assembly
should meet the MIN-MAX dimensions shown in Figure 2.

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.
Use the following charts for calculating spreader gross weight and minimum tractor weight:

TRACTOR/TRAILER PLUG WIRING
The spreader is designed to work with a standard 7-Way, Round Pin Plug. For all lights and accessories to work
correctly, ensure that your tractor is wired as illustrated.
NOTICE!! Some tractors may not have all terminals wired from the factory. Spreader accessories such as the
Electric Gate Height Indicator and Reverse Apron Alarm are wired from our factory to utilize the accessory / 12V
terminal as a power source. Owners may choose to wire the tractor plug to a keyed power source or change the
wiring on the spreader plug to a different pin (such as the flood lights or tail / running lights).
HYDRAULICS
There are UP TO 3 hydraulic circuits on the spreader depending on options equipped.
1. One circuit powers the hydraulic metering gate. Gate is raised / lowered by (2) hydraulic cylinders
connected in parallel. Tractor couplers identified by green color grips.
2. The second circuit powers the hydraulic apron. The MS series pintle chain apron allows reverse operation
to free up clogs. Reverse hydraulics are plumbed through an orifice to run at a slow speed. DO NOT RUN
THE APRON IN REVERSE LONGER THAN NEEDED. An audible warning device at the front of the
spreader alerts the operator of reverse operation. Tractor couplers identified by yellow color grips.
3. The third circuit powers the hood on the combination beater attachment. Hood is raised / lowered by
(2) hydraulic cylinders connected in parallel. Tractor couplers identified by blue color grips.
Therefore, the tractor requires 2-3 sets of remote ports, operated by valves inside the tractor cab.
TRACTOR RELIEF SETTINGS SHALL NOT EXCEED 3000 PSI

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.
Optional Auto Apron Tensioner System
The optional automatic apron tensioner system utilizes (4) hydraulic cylinders at the front of the spreader to
maintain constant tension on the apron chain. When applying hydraulics to activate the apron, the cylinders extend
until they reach a minimum, preset PSI before the apron will start (forward and reverse). Check valves prohibit the
cylinders from retracting, however, a built-in pressure relief valve protects the cylinders from failure. System
pressure can be monitored via a pressure gauge at the RH Front of the spreader. A drain valve in the same
location is used to remove pressure and fluid from the system for maintenance. See page 28 for maintenance
information.
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. (Ø2” Optional)
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 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.

THE SPREADER.
LOADING
1. Check that the hydraulic end gate is closed, Figure 3.
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!
