Most farm accidents, like industrial, home and high-
way 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 acci-
dent occurs.
Regardless of the care used in the design and con-
struction of farm equipment, there are many points
that cannot be completely safe-guarded without in-
terfering 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
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!!
lAlways Wear Eye Protection When Operating Or Servicing Spreader.
lBe Sure All Movement Has Stopped, The PTO Is Disconnected, The Tractor Is Shut Off And The Ignition Key
Is Removed Before Servicing The Spreader Or Components.
lEscaping Hydraulic Fluid Under Pressure Can Penetrate The Skin And Cause Serious Injury. Relieve All Pres-
sure From The Hydraulic System Before Connecting Or Disconnecting The Lines Or Making Repairs. Check
All Hoses And Fittings Before Start-up And Periodically During Operation.
lNever Make Any Alterations Or Modifications To This Equipment.
FAILURE TO HEED MAY RESULT IN SERIOUS PERSONAL INJURY OR DEATH

PRE-OPERATION
GENERAL
Read the entire Owners 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, dis-
connect 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.
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 (ham-
mer-strap) can cause interference with the PTO
driveline IID (implement input driveline). This interfer-
ence 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 guard-
ing 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 maxi-
mum 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 capacities as
specified by the spreader manufacturer are as follows:

SOURCE: ASAE
NOTICE! Heaped loads have significantly higher capaci-
ties resulting in increased weight and higher center of
gravity, requiring extra precaution during operation.
THEORY OF OPERATION
The spreader rear beaters are driven directly by the
tractor PTO.
The spreader rear end gate and the apron are hydrau-
lic driven. A single set of hydraulic hoses connected to
the tractor hydraulic system is used.
A directional valve is incorporated in the spreader hy-
draulic system which directs hydraulic flow to the rear
end gate only, when the gate is closed. With the gate
closed, applying the tractor hydraulics will open the
gate and as the gate opens, the directional valve is
acted upon by the gate arm and will direct hydraulic
flow to automatically start the apron drive motor.
When unloading is complete, the tractor hydraulic le-
ver is reversed to lower the gate and when the gate is
closed, the directional valve will stop hydraulic flow to
the apron motor. Furthermore, a check valve in the
apron motor circuit will prevent the apron drive motor
from running backwards. The check valve will also
prevent incorrect apron operation if the hydraulic
hoses are accidentally reversed at the tractor.
HYDRAULIC SYSTEM
General
There are two hydraulic systems available for this
spreader. Both systems are shipped for tractor closed
center hydraulics. If using a tractor with open center
hydraulics, instructions to convert the spreader system
to open center are given on page 13. Most late model
tractors are closed center systems. If in doubt, contact
your tractor dealer for information.
The standard spreader hydraulic system does not in-
clude an on board flow control to regulate the apron
speed. Instead, the tractor must have an adjustable
flow control lever (turtle/rabbit icons) and this lever is
used to regulate the spreader apron speed.
If your tractor does not have adjustable flow control,
then your spreader must be equipped with the optional
on board flow control system. This system includes a
motorized flow control to regulate the spreader apron
speed. The motorized valve is adjusted by an electric
control box placed in the tractor cab and connected to
the tractor 12 VDC power source. See figure 5.
MODEL: VB750 Page 12

CONVERTING A SPREADER FROM
CLOSED CENTER TO OPEN CENTER
WARNING
ESCAPING HYDRAULIC FLUID UNDER PRESSURE
CAN PENETRATE THE SKIN AND CAUSE SERIOUS
INJURY. RELIEVE ALL PRESSURE FROM THE
HYDRAULIC SYSTEM BEFORE CONNECTING OR
DISCONNECTING THE LINES OR MAKING
REPAIRS. CHECK ALL HOSES AND FITTINGS
BEFORE START-UP AND PERIODICALLY DURING
OPERATION.
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 reser-
voir. This is done by converting your spreader to open
center as instructed in the following.
If you are not sure of your system, contact your tractor
dealer.
Page 13 MODEL: VB750
FIGURE 3. TO CONVERT ON NON FLOW CONTROLLED CLOSED CENTER SYSTEM TO OPEN CENTER

NOTICE! For tractors with closed center system and
load sensing that has a priority flow circuit that is man-
ually adjustable, your spreader must have the optional
on board flow control and it must be converted to an
open center system. This is not a tractor lever oper-
ated system.
To Convert Standard Non Flow Controlled Closed
Center System To Open Center
See figure 3 for instructions in suggested numbered
sequence.
A new elbow fitting is required, see page 52 for part
numbers.
To Convert Optional On Board Flow Controlled

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.
Use Safety Chain
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 ON FIGURE 6.
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 or-
dered on page 24.
Use Lights
Optional lights (see page 48) are offered for your
spreader. Lights are recommended for any spreader
operated on public roads and may be a requirement.
If equipped with lights, plug the electric plug into the
tractor trailer electrical receptacle.

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
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 two hydraulic hoses from the
spreader a set of remote ports on the tractor.
NOTICE! The return line on the spreader apron motor
has a check valve in it so that the apron can not be
operated in the wrong direction. If the hoses are re-
versed, 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 lok connec-
tors together. See figure 5 for mounting instruc-
tions.
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
FIGURE 7. SPREADER HOOK UP
FIGURE 8. HYDRAULIC END GATE,

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, re-
sulting 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 applica-
tion 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. When the end gate begins to open, the apron
drive will start automatically.
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 optional on board flow control with electric con-
trol box, turn the electric control to “ON”. Turn the
knob CW to increase or CCW to decrease applica-
tion rate. Return switch to “OFF” when spreading is
completed, figure 5.
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 recom-
mended to operate at or near engine PTO speed.
9. When the spreader is empty, stop the PTO.
10. Reverse the tractor hydraulic lever. This will close
the gate and stop the apron.
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.

CAUSE SERIOUS INJURY OR DEATH.
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.
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.
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.
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 neces-
sary 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 trac-
tor 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
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.

ADJUSTMENTS
Apron Chain
The apron chain is adjusted by (4) adjuster bolts
located on the front of the box frame, figure 13. Adjust
the 1-1/8” bolts so the chain is elevated above the
plastic slide rails for 36” as illustrated on figure 10.
When there is no more adjustment left on the adjuster
screws, loosen the nuts on the bolts and push the
bolts in as far as they will go. Then remove a link from
each chain and readjust the apron chain
NOTICE! Chain must run centered on the front nylon
rollers.
