MODEL: VB375
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.
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 many thousand serious injuries
each year. That rule is “NEVER ATTEMPT TO
CLEAN, OIL, OR ADJUST A MACHINE WHILE
IN MOTION”.
-NATIONAL SAFETY COUNCIL
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!!

MODEL: VB375
Page 12
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
INJURY 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
dam- aged 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
The spreader is designed to be operated by a
1000 RPM PTO tractor output (Standard).
The PTO drive shaft assembly is designed to
operate with tractors conforming to the industry
standard shown on figure 1 for 1000 RPM PTO
output.
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 pre-
vent 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 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 con- sider that for your conditions. The
loaded weight capacities as specified bythe
spreader manufacturer are as follows:
Tractor Towing Size Requirements
Use the following chart for calculating the
minimum tractor weight.
HYDRAULICSYSTEM
General
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, one set for the hydraulic apron drive and
one set for the hydraulic end gate.
Three types of hydraulic operating systems are
available for the apron drive on the spreader.
1. The Manual Flow Control system has an
adjustable flow control valve on the spreader
which is manually controlled bytwisting a
“control hose” which 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. See Figure 3.

FIGURE 3. MANUAL APRON CHAIN FLOW
CONTROL
2. An Electric Flow Control system is available to
replace the “control hose” described above.
This system has a motorized flow control valve
on the spreader and an electric control box
placed on the tractor is used to control this
valve. See Figure 4.
3. The Standard system utilizes tractor lever flow
control. This system requires that the tractor
have an adjustable flow control lever
(rabbit/turtle) operated valve, there is no
adjustable flow control valve on the spreader
when this option is purchased.

FIGURE 4. OPTIONAL ELECTRIC FLOW VALVE
CONTROLLER
Set Up for Open Or Closed Center Hydraulic
Systems
1. Most late model tractors use a closed center
hydraulic system which only pumps oil as
required. Some other tractors may have an
open center system which pumps oil
continuously, in which case provision must be
made to allow excess flow back to the tractor
reservoir. If you are not sure of your system,
contact your tractor dealer.
2. Spreaders with manual or electric control are
shipped from the factory, set up for open center
tractors. To convert for a closed center, close the
ball valve by rotating the handle perpendicular to
the valve as illustrated on Figure 5.
3. Spreaders with tractor lever operated flow control
(no flow control valve or ball valve on spreader)
are shipped from the factory set up for closed
center. If you require Open Center, then a
conversion must be made as illustrated on
Figure 6.
NOTICE! For tractors with closed center system and
load sensing that has a priority flow circuit that is
manually adjustable, the ball Valve must be open.
This is not a tractor lever operated system.
ELECTRIC CONTROL INSTALLATION FOR
OPTIONAL ON-BOARD FLOW CONTROL SYSTEM
1. Locate the controller on the tractor where it is
easily accessible to operate.
2. Connect the electrical leads to the tractor’s
12VDC power source.
3. When hooking up the spreader, connect the
controller to the motorized control valve at the
“twist-lock” connector.

TRANSPORTING
General
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.
WARNING
BE SURE THE SLOW MOVING VEHICLE SIGN IS
INSTALLED ON THE REAR OF THE SPREADER
FOR TRANSPORTING ON ROADWAYS. KEEP
THIS SIGN AND ALL REFLECTIVE DECALS
CLEAN. FAIL- URE TO HEED MAY RESULT IN
SERIOUS PER- SONAL INJURY OR DEATH.
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 SERI-
OUS PERSONAL INJURY OR DEATH.
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 slip-
pery 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 le-
gal 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
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 AT-
TACHMENT IS ILLUSTRATED.
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.
Safety chain designed for this spreader can be
ordered on page 23.
Use of Lights
Highway lights are standard for your spreader. Lights
are recommended for any spreader operated on
public roads and may be required by law.
If equipped with lights, plug the electric plug into the
tractor trailer electrical receptacle when hooking
spreader to tractor.

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.
TRACTOR HOOKUP
FIGURE 7. SPREADER HOOK UP
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.
1. Hook the spreader hitch to the tractor
drawbar with 1 3/8” secured hitch pin.
2. Raise the jack off the ground. Remove the
jack hub pin and rotate the jack to horizontal
storage position and secure with the pin,
figure 7.
3. Connect the PTO drive shaft to the tractor
PTO output shaft and be sure it is locked to
the tractor shaft.
4. Connect the hydraulic hoses from the
spreader to remote ports on the tractor.
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.
5. If you have an optional on board flow control
with electric control system, plug the twist lock
connectors together. See figure 5.
LOADING
1. Check that the end gate is closed, figure 8. When
the spreader is parked for loading, shift the
tractor to neutral or park and set the brakes. The
moisture content of the manure will determine
how full the spreader can be loaded so that no
manure spills out.
2. You will probably be able to load solid manure
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.
NOTICE! It is unlawful to allow slurry to splash or leak
onto public roads.

UNLOADING
DANGER
KEEP AWAY AND KEEP OTHERS CLEAR OF RO-
TATING BEATERS AT REAR OF SPREADER.
SERI- OUS INJURY OR AMPUTATION COULD
RESULT.
WARNING
MAKE CERTAIN EVERYONE IS CLEAR OF
EQUIP- MENT BEFORE APPLYING POWER.
FAILURE TO HEED MAY RESULT IN SERIOUS
PERSONAL IN- JURY OR DEATH.
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 uni-
form and about 30 feet wide or more for cattle
manure and about 20 feet wide for poultry manure.
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.
CAUTION
DO NOT OPERATE APRON CHAIN WITHOUT
RAISING END GATE FIRST. FAILURE TO HEED
MAY RESULT IN EQUIPMENT DAMAGE.
1. When you are ready to begin spreading
application on the field, slowly engage the
tractor PTO clutch and then increase PTO to
operating speed.
2. Open the hydraulic end gate, figure 8, 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 Fully Open and the
PTO is up to speed, engage the apron.
4. For standard non flow control systems, regulate
the apron speed with the tractor hydraulic
system adjustable flow control lever
(rabbit/turtle icons).
5. For electric flow control, turn the electric controlto
“ON”. Turn the knob CW to increase or CCW to
decrease application rate. Return switch to “OFF”
when spreading is completed, figure 4.
6. For solid manure, start the apron at a slow rate of
speed.
7. 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 can 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.
8. 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.
9. When the spreader is empty, stop the PTO.
10. Stop the apron chain so there is no chain slat
under the hydraulic end gate, Figure 8. Then close
the end gate.
MANDATORY SAFETY
SHUTDOWN PROCEDURE

REAR-AUTOMATIC OVER RUNNING
CLUTCH
(See figure 9)
1. If the PTO drive becomes over loaded, the clutch
will disengage, causing an audible clattering
noise.
FIGURE 9. AUTOMATIC OVER RUNNING CLUTCH
2. If the clutch disengages, stop tractor hydraulic
flow. Disengage the PTO and allow it to coast
down. The clutch will re-engage at slow speed
if the over load has subsided.
3. At slow speed, re-engage the PTO and allow
the beaters to run freely. Restart the hydraulic
flow and resume operation.
4. 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. A foreign object such as a rock
may be found to be the cause of over load.
5. When the clog has been cleared, restart the
tractor and at idle speed, engage the PTO until
the beaters fun freely. Increase the PTO speed
and then engage the hydraulic flow to operate
the apron drive and resume operation.
MANDATORY SAFETY SHUTDOWN
PROCEDURE
BEFORE unclogging, cleaning, adjusting, lubricating
