Model 390 Page 9
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!!

Page 10 Model 390
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, 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 damaged
parts.
5. The tractor half of the PTO drive shaft assembly
must be locked securely to the tractor output shaft.
TRACTOR HOOKUP
Tractor Requirements:
1. The spreader is designed to be operated by a 540
rpm PTO tractor output. In addition, 1 set of tractor re-
mote hydraulic ports are required, to operate the apron
drive and a second set of ports will be required for an
optional hydraulic end gate.
2. The PTO drive shaft assembly is designed to oper-
ate with tractors conforming to the industry standard
shown on Figure 1 for 540 RPM PTO output.
Tractor Size
1. 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.
2. 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:

Tractor Hookup
1. Hook the spreader hitch to the tractor drawbar with
secured hitch pin conforming to the pin hole size in the
spreader hitch.

SPECIFICATION

Model 390 Page 11
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 2.
3. Connect the PTO drive shaft to the tractor PTO out-
put shaft and be sure it is locked to the tractor shaft.
4. If your spreader has an optional fine spread pan, tie
the rope control to a convenient place for operation
from the tractor seat.
Hydraulic Apron Drive
1. Connect the two hydraulic hoses for the apron drive
to a set of remote ports on the tractor. These are the
two hoses coming from the hydraulic flow control valve.
NOTE: One of the lines going to the flow control has a
check valve in it so that the apron cannot be operated
in the wrong direction. This line must be connected to
the tractor return port. If the hoses are reversed, the
apron will not operate and the hoses should be
switched, see Figure 3 or Figure 4.
2. A “control hose” is connected to the flow control lever
with the opposite end having a bracket to hook at a
convenient location on the tractor for operator conven-
ience. The flow control lever has a tension screw ad-
justment to regulate force to retain settings, see Figure
3 or Figure 4.
3. Connect the two hydraulic hoses for the end gate to
a second pair of tractor remote ports.
Hydraulic System
1. Most late model tractors use a Closed Center hy-
draulic 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 through the return hose
back to the tractor reservoir. If you are not sure of your
system, contact your tractor dealer.
2. The spreader is normally shipped with the apron
drive flow control valve plumbed for Open Centers as il-
lustrated on Figure 3. If you have a Closed Center,
close the ball valve as shown on Figure 4.

TRANSPORTING
1. 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 SERIOUS
PERSONAL INJURY OR DEATH.
2. 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 slippery conditions such as traveling over areas pre-
viously spread with manure. If possible, avoid spread-
ing over areas where manure has been previously ap-
plied.
3. If you will travel on public roadways and it is legal to
do so, you must know all rules governing such opera-
tion. This will include lighting and brake requirements in
addition to traffic rules. You may also be required to in-
stall a safety chain on the spreader.
4. Use Safety Chain:
CAUTION
A SAFETY CHAIN SHOULD BE INSTALLED TO RE-
TAIN THE CONNECTION BETWEEN TRACTOR (OR
OTHER TOWING VEHICLE) AND SPREADER
WHENEVER TRAVELING ON PUBLIC ROADS. A
SUGGESTED ATTACHMENT IS ILLUSTRATED ON
Figure 5.
1. 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.
2. The length of the safety chain is not to be any long-
er 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 18.

OPERATION
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.
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.
LOADING
1. If you have an optional hydraulic end gate or fine
spread pan, be sure they are closed, Figure 6 and
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.
NOTE: It is unlawful to allow slurry to splash or leak on-
to public roads.
UNLOADING
WARNING
MAKE CERTAIN EVERYONE IS CLEAR OF EQUIP-
MENT BEFORE APPLYING POWER. FAILURE TO
HEED MAY RESULT IN SERIOUS PERSONAL INJU-
RY OR DEATH.
DANGER
KEEP AWAY AND KEEP OTHERS CLEAR OF RO-
TATING BEATERS AT REAR OF SPREADER. SERI-
OUS INJURY OR AMPUTATION COULD RESULT.
1. 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 uniform and
about the width of the spreader. 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.
2. Perform the following operations when you are
ready to begin spreading application on the field, de-
pending on the options your spreader is equipped with.
Hydraulic Apron Drive
1. Turn hydraulic power on with tractor hydraulic con-
trol and then start the apron chain. This is done from
the tractor by turning the flow control clockwise, locat-
ed at the front of the spreader. This control is operated
from the tractor by twisting the “hose control”, Figure 7.
“OFF” is when this control is rotated fully CCW. For
solid manure, start the apron at a slow rate of speed.
Start application onto the field. Increase speed of
apron chain for a heavier application.
2. There is a tension screw that can be adjusted to
regulate the force required to operate the flow control
valve, see Figure 3 or Figure 4.
3. Further control of the application rate is possible by
changing ground speed (transmission gear selection).
For optimum trouble free performance it is recom-
mended to operate at or near engine PTO speed.
4. When the spreader is unloaded, or when the ma-
nure level is below the beater, it is possible to stop the
beater by disengaging the PTO on the tractor. This al-
lows the spreader apron to continue without the beat-
ers running for clean out.
5. When the spreader is empty, stop the PTO and
then stop the apron chain so there is no chain slat un-
der the hydraulic end gate, FIGURE 8. Then close the
end gate.
Optional Fine Spread Pan
If the pan is left closed, the spread pattern will be thin-
ner, more even, and narrower than normal. If normal
spreading is desired, trip the pan by pulling the rope
control immediately after beginning the spread applica-
tion, see Figure 6.

Page 14 Model 390
Hydraulic End Gate
1. Open the end gate with the tractor hydraulic control,
FIGURE 8, and slowly engage the tractor PTO clutch.
This can be done while traveling forward to avoid a
heavier application at the edge of the field than de-
sired. The end gate must be completely open.
CAUTION
DO NOT OPERATE APRON CHAIN WITHOUT RAIS-
ING END GATE FIRST. FAILURE TO HEED MAY
RESULT IN EQUIPMENT DAMAGE.
2. Once the end gate has been fully opened, bring the
PTO up to speed and start application onto the field.
3. When the spreader is empty, stop the PTO and dis-
engage the hydraulic flow on the tractor so there is no
chain slat under the hydraulic end gate if so equipped,
FIGURE 8. Then close the end gate.
UNHOOK SPREADER FROM TRACTOR
1. Park the spreader, set tractor parking brake, and
turn off all power.
2. Park your spreader on level ground and place
blocks ahead of and behind the wheels before unhook-
ing from tractor.
3. If the fine spread pan was tripped, shut it by pulling
it back to the closed position where it will latch in place.
4. Do not unhitch a loaded spreader from the tractor
leaving it supported by only the jack.
5. Remove the PTO shaft from the tractor and the hy-
draulic hoses. Unhook the hitch.
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.

MAINTENANCE, LUBRICATION & ADJUSTMENTS
WARNING
DISCONNECT PTO DRIVE SHAFT AND HYDRAULIC
HOSES BEFORE CLEANING, ADJUSTING OR SER-
VICING THIS MACHINE. FAILURE TO HEED MAY
RESULT IN SERIOUS PERSONAL INJURY OR
DEATH.
DANGER
IT IS NOT SAFE TO CLEAN OR SERVICE THE
SPREADER WITH POWER OPERATING. PTO DRIVE
AND HYDRAULICS MUST BE DISCONNECTED.
WHEELS: Check after first hour of towing and pe-
riodically thereafter. The wheel studs should be torqued
to 170 foot pounds, in a crisscross manner.
TIRE PRESSURE:
22.5x8.25, recommended pressure 45-60 psi max.
W14Cx16.1, recommended pressure 36 psi max.
425-65R, recommended pressure 45-90 psi max.
WARNING
NEVER INFLATE BEYOND RIM OR TIRE MAN-
UFACTURER’S APPROVED PSI RATING. WHILE IN-
FLATING, STAY OUT OF THE TRAJECTORY &
STAND CLEAR OF TIRE/WHEEL ASSEMBLY. A TIRE
BLOW OUT OR RIM/WHEEL FAILURE CAN CAUSE
SERIOUS INJURY OR DEATH.
CLEANING AND STORAGE
Before storing this spreader for an extended period of
time, perform the following:
1. Allow the spreader to completely clean out the last
load.
2. Hose off all manure from the spreader, particularly
getting the end gate and spread pan mechanisms
clean. The water can be drained into your manure stor-
age pit or if the optional gate is left closed, the water
can be taken to the field and spread.
3. If pressure washing spreader, be careful not to
wash directly on or close to bearing seals. The high
pressure can destroy the seal and force water into the
bearing causing it to rust and fail. Avoid pressure wash-
ing painted areas of the spreader too close with washer
as the pressure can strip paint on scratched areas
caused from scraping clean.
4. Manure is acidic and should not be left on painted
areas for a long time because it will lift paint from metal.
Unpainted metal will corrode causing holes to rust
through metal guards or even fall off the machine. If
this should happen, guards must be replaced immedi-
ately.
WARNING
DO NOT OPERATE SPREADER WITH ANY GUARD
OPEN OR MISSING. ROTATING PARTS CAN DIS-
MEMBER OR KILL.
5. After cleaning, lube the spreader to exclude mois-
ture from bearings and prevent condensation from
forming during storage. Apply oil to roller chain drives.
6. This is a good time to inspect all adjustments and
check for parts that need repair or replacement. Per-
forming these tasks now will guarantee that the
spreader is ready for use at the beginning of the next
season.
LUBRICATION
Maintain oil level in the apron drive gear reducer
at the check level plug, located at rear drive. When re-
quired, refill with SAE 85-140 Moly Fortified gear lube
or Synthetic SAE 70-90 gear lube. Figure 11.
Maintain oil level in the beater drive gear reducer
at the check level plug. When required, refill with SAE

necting the PTO shaft with the front roller chain drive.
Grease these bearing one pump, every 8 hours. Figure
10.
Lubricate the PTO universal joints with 1 pump of
grease every 8 hrs. Lubricate the telescoping members
of the drive shaft with 4-8 pumps every 8 hrs. Figure
10.
Grease the beater clutch, two pumps every 8
hours. NOTE: This clutch is used only for “over run”
when the PTO is stopped, preventing damage to the
tractor. Figure 11.

SHEAR PIN HUBS
1. The spreader drive train is protected with a shear
pin hub at the front end of the side drive shaft. If the
shear bolts shear, determine cause of overload and
correct.
2. Realign holes in sprocket and shear pin hub and re-
place bolts. Snug lock nuts only enough to remove all
slack. Do Not Tighten completely.
Use 3/8x1-1/4" Grade 2 bolts and 3/8" lock nuts
only. Figure 12.
ADJUSTMENT
Apron Chain
The apron chain is adjusted by (2) adjuster
screws located on the front of the box frame. Adjust the
screws so there is no chain sag on the return side and
chain is never closer than 5" to the spreader axle.
When there is no more adjustment left on the adjuster
screws, loosen the nuts on the screws and push the
screws in as far as they will go. Then remove a link
from each chain and readjust the apron chain. Figure
10.
Roller Chain Adjustment
The front, main beater drive chain is automatically
tensioned with a spring loaded tensioner. Proper chain
tension is 1/2 to 3/4" of deflection at midspan on the
loaded chain strand. The automatic tension can be ad-
justed with the spring eye bolt. Figure 12.
The upper beater drive chain is automatically ten-
sioned with a spring loaded tensioner. Proper chain
tension is 1/2 to 3/4" of deflection at midspan on the
loaded chain strand. The automatic tension can be ad-
justed with the spring eye bolt. Figure 9.
