ACCIDENTS
CAN BE PREVENTED
WITH YOUR HELP!
No accident-prevention program can be successful without the whole-hearted
cooperation of the person who is directly responsible for the operation of the equipment.
A large number of accidents can be prevented only by the operator anticipating
the result before the accident is caused and doing something about it. No power-driven
equipment, whether it be transportation or processing, whether it be on the highway, in
the harvest field, or in the industrial plant, can be safer than the person who is at the
controls. If accidents are to be prevented--and they can be prevented--it will be done
by the operators who accept the full measure of their responsibility.
It is true that the designer, the manufacturer, and the safety engineer can help;
and they will help, but their combined efforts can be wiped out by a single careless act
of the operator.
It is said that, "the best kind of a safety device is a careful operator." We, at
Unverferth Mfg. Co., Inc. ask that you be that kind of operator.
SAFETY PRECAUTIONS
Read this manual carefully before operating.
Never enter the grain cart while the auger is running.
Make sure PTO guard is kept in place.
Never allow anyone on the unit while moving through the field.
Be careful when moving unit near electrical lines with discharge auger up.
Never tow a loaded unit more than 8 m.p.h. or on a road.
Never exceed the maximum recommended hitch pin size which allows for
uneven terrain.
Make use of night-time lighting provided on your new cart.
Use caution when unloading on the go, while moving through gullies, wash-
outs, and uneven terrain.
Always check behind you before backing up.
Counter-weight your tractor front end.
Be careful on steep slopes. A loaded grain cart is hard to stop.
Do not fold or unfold auger while moving.
When auger is not in use, be sure to fold to the rest position.
Never unhook a grain cart while it is being loaded.
Turn the tractor power off and remove the key from the ignition before servicing
the attached implement.
Tow only an empty cart on-road and have a rated safety chain attached.

SET-UP FOR FIELD OPERATION
Your grain cart comes set-up with exception of wheel/tire installation, side extensions, ladder,
auger extension chute, electrical hook-up to tractor, and tire pressure check. If your
implement dealer has not set up the preceding items, the procedure is simple.
SIDE EXTENSION SET-UP
Refer to parts page in Section 2 for extension placement. Hardware is stored behind right
axle standard of grain cart.
1. Remove transport screws and set extensions
in their respective locations.
2. Secure extension through mounting lug holes
and holes provided in corners.
Folding Boards:
1. Rotate extensions up into position and secure
at corner holes.
2. Attach center support hardware.
3. Tighten all hardware, including hinge bolts.
AUGER EXTENSION CHUTE

JACK
Use jack to support an empty grain cart, never a loaded
grain cart.....always have a loaded grain cart hooked to
tractor. Remove jack from storage on inside of left frame
and install on mounting spud behind hitch. Important:
Return jack to storage location after cart is hitched to
tractor.
WHEEL NUTS
Check all wheel nuts for tightness before first load. Failure to do so may damage wheel nut
seats. Once seats are damaged, it will become impossible to keep nuts tight. Tighten nuts
to 400 ft. lbs. Re-tighten after first three loads and check periodically during first season of
use.
TIRE PRESSURE
The following is to be used as a general guide for tire inflation and figures can vary depending
on specific brand of tire used. It is important that tires are inspected after unit is loaded. The

1. Make sure the flow control door is in the closed position before loading into the
cart.
2. Engage PTO at a low RPM; increase tractor RPM to desired speed.
3. Open the flow control to desired rate.
4. Use the flow control opening to slow the rate of the flow rather than the tractor's
RPM. NOTE: If overload causes the clutch to slip (standard PTO drive) or
motor to stall (hydraulic drive), stop auger immediately. Excessive heating of the
clutch will require replacement of internal parts. Close flow control door and
relieve auger unload pressure by opening bottom pit dump door to remove some
grain from auger.
5. It is not advisable to disengage the auger with the flow control open. Excessive
start-up torque may result, putting stress on the cart driveline and your tractor.
6. Properly identify the tractor remotes as to hook-up the flow control and auger
fold. A mix-up can damage the auger drive system.
7. Under any circumstances, DO NOT enter the cart with the auger or tractor
running.
8. When folding the auger into the unloading position, make sure you have given
sufficient time for the cylinder to rotate the bell crank into an over-center
position.
9. It is strongly advised that the unloaded auger always be returned to the transport
position when not in use.
OPERATION IN FIELD
TRACTOR HOOK-UP
HYDRAULIC HOOK-UP
-- Properly identify the hoses for the auger fold and the flow control operation.
-- It is advisable to use the hydraulic control lever closest to the operator (most
commonly known as control lever No. 1) to activate the flow control.
-- Make sure sufficient counter-weight is used on the tractor's front-end.
-- Move draw bar into closest position for even terrain.
-- Make sure draw bar length and PTO telescoping limits are adequate for
uneven terrain, gullies, rice levees etc.
-- Never exceed the maximum recommended hitch pin size which allows for
uneven terrain. See Chart below.
-- Install hardened washer of hitch pin diameter between bottom of swivel ball
and tractor draw bar.

The auger fold linkage is adjusted at the factory and under normal operating conditions
should not require adjustment. Disassembly for service or slight wear in the linkage pins may
necessitate the need for adjustment. The 1/8" compression dimension is necessary for a good
seal at the auger flanges and snap locking at the end of the cylinder stroke.
1. Fold the upper auger into the operating position and clamp flanges to secure.
2. Extend hydraulic cylinder slightly (1/8") to relieve load. Remove T-Bar yoke pin.
3. Retract cylinder to end of stroke.
4. Rotate T-Bar yoke as necessary to position rockshaft arm hole approximately 1/8" past T-
Bar yoke holes when T-Bar linkage and rockshaft arm are in a straight line.
5. Extend cylinder slightly again to line up holes in T-Bar yoke and rockshaft arm. Install pin
and secure with nut. Remove temporary clamp before cycling auger fold operation.
6. Retract hydraulic cylinder. Check for sealing at auger tube flanges and for "straight-line
lock snap" of linkage. Cycle linkage by fully lowering and raising auger tube. Recheck
linkage. Readjust as necessary.

HYDRAULIC AUGER OPERATION
For PTO & DIRECT DRIVE Applications
250946
1. Initial start-up: Flow Door is to be closed.
2. With flow door closed, engage hydraulic motor with maximum oil flow from
tractor. NOTE: Free running auger oil pressure will range 500 PSI or less.
3. The pressure gauge will register system work load as flow door is opened.
Slowly open flow door to #1 setting on auger tube decal gauge. While
monitoring the auger discharge rate and hydraulic pressure, gradually increase
flow door opening to approximately 2 - 2 1/2 setting. Watch the pressure gauge
and stop opening door once pressure reaches 2000 PSI.
4. Peak performance is obtained by matching your highest continuous auger
rpm to the flow door opening setting. It is necessary to initially monitor the
auger speed and adjust the flow door UP or DOWN to arrive at the optimum
output performance. If the flow door is opened too wide, the oil pressure will
rise, but the GPM and the hydraulic motor RPM could slow down - resulting in
less auger output. Also if the tractor has a higher GPM output, it is possible that
the flow door could be opened wider and still maintain performance.
5. Bushels-per-minute output depends on the following factors:
a. Oil flow (GPM) from tractor.
b. Flow door opening setting.
c. Grain moisture content.
6. The hydraulic motor is capable of handling 32 to 35 GPM. If extra hydraulic
ports are available on the tractor, it is possible to increase oil flow to the
hydraulic motor by teeing together two pressure ports to the single pressure
hose, and teeing two hoses from return hose to the tractor return ports.

ADJUSTABLE UNLOADING CHUTE (OPTIONAL)
250957
INSTALLATION:
1. Remove existing chute.
2. Fold overlap and snap four end snaps.
3. Slide chute over outlet shroud with
overlap towards hitch.
4. Install top and bottom strips over chute
and fasten with existing capscrews,
flatwashers and locknuts.
5. To adjust to desired length, unsnap
overlap, roll chute on outside and snap
in place.
SCALE WEIGHING PROCEDURE
Turn scale on and let it warm-up at least 15 minutes.
Zero balance scale by pushing the "Net/Gross" button, and then the "Zero" button
within 3 seconds. This should be done where cart is going to be unloaded (on level
ground if possible).
Load cart and let scale total up weight. When cart is full drive up to truck and stop.
After scale settles on a number, push the "Tare" button. Scale indicator will show zero.
Now start unloading cart. When truck is full or cart is empty, the negative amount
shown on scale is actual product in truck.
Now push the "Net/Gross" button. This will put the scale back into the gross
weighing mode again. If the cart has grain in it yet, it will tell you how much weight is
left on the cart. You can now load the cart again and repeat the same unloading pro-
cess. You should try to get the cart empty a few times during the day so you can rebal-
ance the scale.

To avoid injury do not clean, adjust, unclog, or
service PTO driven equipment when the tractor en-
gine is running.
Never exceed the recommended operating speed for
the particular equipment in use.
PTO drive shafts must only be used for their in-
tended purpose.
PTO drive shafts, clutches and freewheels are de-
signed for specific machine types and power require-
ments. They must not be replaced by other models.
NOTE: The tractor and implement manufacturers'
operating instructions.
Ensure that the PTO shaft is securely connected.
This Safety Alert Symbol means Attention!
Become Alert! Your safety is involved!
OPERATING THE PTO
When finishing operation of PTO driven equipment,
shift PTO control to neutral, shut off the engine and
wait until the PTO stops before getting off the tractor
and disconnecting the equipment.
Do not wear loose clothing when operating the power
take-off, or when near rotating equipment.
When operating stationary PTO driven equipment,
always apply the tractor parking brake lock and block
the rear wheels front and back.
PTO SHAFT & CLUTCH
A. Only use a completely shielded drive
system:
PTO drive systems with complete
shielding, include the tractor master
shield and implement shielding installed
all the time. If any component of the
shield system has been removed for
any reason it, or a repair part, must be
installed before operation.
BB. Note the maximum operating length LB!
Try to obtain the greatest possible overlap without
bottoming out in the maximum operating condi-
tion. In its working position, the PTO drive shaft
should not be extended by more than half the
telescoping member overlap P

D. Lubrication (Figs. D1 - D6)
Lubricate with quality grease before starting work and every 8 operating hours.
Clean and grease PTO drive shaft before each prolonged period of non-use.
Molded nipples on the shield near each shield bearing are intended as grease
fittings and should be lubricated every 8 hours of operation!
Telescoping members must have lubrication to operate successfully regardless
of whether a grease fitting is provided for that purpose! Telescoping members
without fittings should be pulled apart and grease should be added manually.
Check and grease the guard tubes in winter to prevent freezing.
D1 D4D2 D3
F. Length adjustment (note: maximum operating
length LB). (Figs. F1 - F4)
1. To adjust length, hold the half-shafts next to each
other in the shortest working position and mark
them.
2. Shorten inner and outer guard tubes equally.
3. Shorten inner and outer sliding profiles by the
same length as the guard tubes.
4. Round off all sharp edges and remove burrs.
Grease sliding profiles.

G. Chains (Figs. G1 - G3)
NOTE: The chain is intended to prevent the shield
from rotating against non-moving parts and thereby
preventing shield damage. A properly installed chain
will increase the service life of the shield.
1. Chains must be fitted so as to allow sufficient
articulation of the shaft in all working positions.
Care must be taken to be sure that chain does not
become entangled with drawbar hitch or other
restrictions during operation or transport of
machine.
2. The PTO drive shaft must not be suspended from
the chain.
J. To dismantle guard: (Figs. J1 - J4)
1. Remove locking screw.
2. Align bearing tabs with cone pockets.
3. Remove half-guard.
4. Remove bearing ring.
G2
2. Friction clutches:
When overload occurs, the torque is limited and
transmitted constantly during the period of slip-
ping. Short-duration torque peaks are limited.
Prior to first utilization and after long
periods out of use, check working of disk
clutch.
a. Tighten nuts until friction disks are released.
