Maximum Weight Of Baled Hay
10% of ration by weight.
ROUGHAGE LENGTH
The mixer is designed to mix complete rations including
roughages which fall within the following length limits.
1. At least 75% of the material is 1-1/2 inches or
shorter.
2. Less than 20% of the material exceeds 2-1/2
inches.
3. Maximum fiber length does not exceed 4 inches.
USE OF BALED HAY
Oswalt mixers are designed to blend feed ingredients
with “dry hay” to obtain a total mixed ration. Dry hay
will have less than 20% moisture. A simple hand test
on three stems of hay will tell you if the hay should be
put into the mixer.
Reach into the core of the bale and remove 3 stems of
hay. Try to bend and break these 3 stems when hold-
ing them between the thumb and forefinger of both
hands. If they snap and break easily the mixer will pro-
cess the hay fairly easily. If the hay is NOT very brittle
and you have to twist, tug, pull, and pinch to break it
apart, you have a “tough hay” condition. Weather and
plant varieties, etc., can generate these conditions.
Conditions That Cause Abnormal Tough Hay
·High Moisture Content (20% plus)
·High Density Bales
·High Grass Content
·Outdoor Storage
·Long Stem Length
·Use of Hay Preservatives
FINE STEM GRASS HAY WITH LENGTHS OVER 16
INCHES Are Not Recommended because they tend to
wrap around the augers unless they are extremely brit-
tle.
When in doubt, throw in a half bale of the questionable
feed to insure hay breaks apart and does not wind or
wad.
If, in your judgement, the baled hay quality comes
within the definition of “tough hay” per above, then it’s
recommended you process the bale to shorter length
prior to adding to the mixer.
LOADING
The loading sequence depends on the type of feed be-
ing used. For this reason, we offer a few suggested
loading sequences to maximize mixer performance
and avoid equipment failure.
NOTE: When is doubt, throw in a half bale of the
questionable feed to insure hay breaks apart and does
not wind or wad in the mixer.
For a ration utilizing “dry hay” the ingredients can be
all added at one time and then mixed. The ingredients
should be added with the mixer stopped to avoid over
processing. The ingredients should be added in the
following order: all dry ingredients (corn, soybeans,
cottonseed, etc.) then the hay, and the remaining ma-
terials last. When all ingredients have been added,
the mixer can be started and mixing completed.
If adding all the materials at once causes mixing prob-
lems or if you have a “tough hay” condition, then add
the ingredients using the following sequence. With the
mixer stopped, add all dry ingredients. The introduc-
tion of the dry ingredients first helps the mixer break
up the hay. Next turn on the mixer and add the hay.
Hay should be broken apart and added at the drive
end of the mixer. Allow the dry materials and hay to
mix until the flakes of hay are broken up. Then add
the remaining materials and complete the mixing. If
this process causes over processing of the ingredi-
ents, shut off the mixer after mixing the hay and dry in-
gredients and restart and complete mixing after all
remaining ingredients have been added.
Page 15

If this process causes mixing problems associated with
the hay, then it is recommended that the hay be pro-
cessed to a shorter length prior to adding to the mixer.
A J-Star bale cutter is recommended to accomplish
this.
NOTE: Round bales should not be incorporated di-
rectly into the mixer without first being processed.
MIXING TIME
Normal mixing time after the last ingredient has been
added.
Trailer 5 min. @540 RPM
Stationary 10 minutes
Total run time (filling, mixing, and discharging) should not ex-
ceed 15 minutes per batch for a trailer and 30 minutes for a
stationary. Use of baled hay in the mix will increase the mix
time for a trailer by 5 minutes and a stationary by 10 min-
utes.
SHEAR PIN
The shear pin assembly is located at the back of the
mixer just in front of the oil bath drive housing, see figure
1.
Extra shear bolts are located in a holder on the right
side of the rear structure, see figure 2.
TRACTOR HYDRAULIC SYSTEM
RECOMMENDATIONS
10 GPM Minimum 15 GPM Maximum
1200 to 1600 PSI Operating Range
Hydraulic system should be self purging.
TRACTOR DRAWBAR
See tractor drawbar as shown in figure 3.
Failure to set drawbar properly may
cause shaft to over extend and separate or bend when
cornering or transporting. Resulting in death or per-
sonal injury.

TRAILER OPERATION
PTO ENGAGEMENT
Avoid high speed sudden engagement of the mixer.
Doing so may cause the shear pin to shear.
CORNERING
Sharp cornering with the pto engaged is not recom-
mended. If it is necessary to mix when cornering, it
should be done at reduced speeds and wide corners
only.
DISCHARGING FEED
The discharge door and conveyor tilt are hydraulically
actuated using the tractor’s remote hydraulic system.
The discharge door and conveyor tilt are sequenced
so when the tractor’s remote hydraulic control lever is
moved one way the conveyor will tilt out and the door
will open. The reverse will happen when the lever is
moved in the other direction. Two hydraulic ports on
the tractor are required.
A hydraulic motor is used to run the discharge con-
veyor chain using the tractor’s remote hydraulic sys-
tem. Moving the tractor’s remote hydraulic control one
way will cause the chain to move in the discharge di-
rection. Moving the lever in the opposite direction will
not move the chain due to a check valve in the mixer
hydraulic system. Two hydraulic ports on the tractor
are required.
To discharge feed, move the hydraulic valve lever on
the tractor to open the door and tilt the conveyor. Move
the other lever to start the conveyor chain. Start the
pto. The discharge rate can be controlled by the posi-
tion of the door and the transmission gear selected.
Reverse this sequence when through discharging.
SCALE SWING MOUNT
The scale head is mounted to a swing arm. The swing
arm is designed to allow scale head viewing from ei-
ther side of the mixer or from the tractor just by rotat-
ing the scale arm before loading or unloading starts.
As a convenience a chain is attached to a scale swing
mount. The chain is used to swing the mount arm from
one side of the mixer to the other.
OPTIONAL SINGLE VALVE CONVERSION
This conversion is used when the tractor has only two
remote hydraulic ports. A control valve is mounted on
the mixer and a rope is attached to the valve handle.
Moving the tractor’s remote hydraulic control lever will
start the conveyor chain in motion. With the tractor
lever still moved the rope is pulled to shift the valve on
the mixer. Shifting this valve tilts the conveyor out and
opens the door. To close the door and tilt the conveyor
back the lever on the tractor must be shifted opposite
and the rope pulled.
SCALE SYSTEM
Refer to the operation book supplied with the scale in-
dicator head.
Page 17

TRANSPORTING
A safety chain should be installed to
retain the connection between the tractor (or other
towing vehicle) and mixer if the hitch connection would
separate; whenever traveling on highways. A sug-
gested attachment is illustrated on figure 4.
The chain must be strong enough to hold the weight of a
loaded mixer. If using a grab hook at the end to secure
the chain to itself, a hook latch must be installed as illus-
trated.
The length of the safety chain is not to be any longer than
necessary to turn without interference. If any chain lengths
or attachment hardware are broken or stretched, repair
before using. Store chain so it does not corrode or be-
come damaged. Do not use this chain for other imple-
ments because the strength and length of chain may not
be adequate. Identify this chain for use on this particular
mixer.
The ratio of the loaded mixer weight compared to the
weight of the towing tractor or other vehicle must not
be greater than 1.50.

STATIONARY OPERATION
MOTOR CURRENT
An ammeter should be installed in the line where it can
monitor motor current. It may be necessary to adjust
the amount of feed that is processed in the mixer to
obtain an amp draw equal to or less than the full load
motor current rating.
DISCHARGING FEED
Manual Operator
To open the discharge door, first pull back on the lock
pin, see figure 5. This pin is positioned close to the
hand wheel hub. With the pin pulled back turn the pin
handle 90 degrees and release. The pin will now stay
disengaged and the hand wheel can be turned to the
desired open position.
When the door is open far enough, turn the pin handle
back 90 degrees and rotate the hand wheel until the
pin drops into the nearest lock hole.
Electric Door Operator
A electric motor drive linear actuator opens and closes
the mixer discharge door. The actuator motor is con-
trolled by a dealer installed switch. Moving the switch
in one direction opens the door and in the other direc-
tion closes the door. The middle position is off, keep-
ing the door in the current position. The actuator can
be stopped in any position to control the flow of feed.
The actuator will “free wheel” at each end of its total
stroke.
NOTE: Always open and close discharge door with the
mixer running. This will prevent high material pressure
against the door which may stall out the actuator mo-
tor.
SCALE SYSTEM
Refer to the operation book supplied with the scale in-
dicator head.

Discharge Conveyor Height
The discharge chute height can be set by positioning
the stop pin in the desired hole of the fold limiter bar,
see figure 6.
Discharge Chute Folding
Folding of the discharge chute is controlled by the ad-
justment of the threaded pivot on the side of the con-
veyor and position of the spring underneath the
conveyor, see figure 7.
Threading the pivot out of the end of the pivot bar will
make the chute fold closed more when the conveyor is
tilted up for storage. Threading the pivot into the pivot
bar will cause the chute to fold down more when dis-
charging feed. If the chute does not rotate down when
conveyor is lowered, move the spring mount so the
spring is stretched longer.
Conveyor Drive Chain
There are adjusting nuts on each side of the conveyor.
Tighten or loosen these nut to allow approximately
1-1/4 inches between the bottom of the chain flight and
the conveyor pan when the chain is pulled up at the
center of the conveyor, see figure 8.
