Introduction
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 be-
fore 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 transport chain attached.

the tractor operator's manual before operating.
Do not wear loose fitting clothes, as they may
catch in moving parts.
Do not allow anyone to ride on the equipment.
Make sure everyone is clear before operating
machine or tractor.
Never play in or on the grain. Flowing grain
traps and suffocates victim in seconds.
Never attempt to operate implement unless you
are in driver’s seat.
Escaping fluid under pressure can penetrate the
skin causing serious injury. Relieve pressure
before disconnecting hydraulic lines or servicing
hydraulic system. See tractor operator's manual
for procedure to relieve pressure.
Use a piece of cardboard or wood to detect
leaks of hydraulic fluid under pressure. Correct
hydraulic leaks immediately.
Do not bend or strike high-pressure lines. Do
not install bent or damaged tubes or hoses.
Repair all oil leaks. Leaks can cause fires,
personal injury, and environmental damage.
Route hoses and lines carefully to prevent pre-
mature failure due to kinking and rubbing against
other parts. Make sure that all clamps, guards
and shields are installed correctly.
IF INJURED BY ESCAPING HYDRAULIC OIL,
SEE A DOCTOR AT ONCE, SERIOUS IN-
FECTION OR REACTION CAN DEVELOP IF
PROPER TREATMENT IS NOT ADMINISTERED
IMMEDIATELY.
Secure drawbar pin with safety lock and lock
tractor drawbar in fixed position.
All machinery should be operated only by trained
and authorized personnel.
To prevent machine damage, use only attach-
ments approved by the manufacturer.
Always shut tractor engine and hydraulic power
unit engine off and remove the keys from igni-
tion before servicing implements.

1-5
Safety
SAFETY
Be sure the tires are inflated to the recom-
mended pressure.
Always make certain everyone and everything
is clear of the machine before beginning op-
eration.
DO NOT allow ANYONE to enter or climb on
the Grain Cart during operation. If entry is
necessary, be sure P.T.O. is disengaged, chute
door is closed, tractor engine is off, the igni-
tion key removed and tractor brakes are locked
before entry.
TRANSPORTING
Comply with state and local laws governing
highway safety when moving machinery on
public roadways.
Use accessory lighting or warning lights when
transporting at night to adequately warn opera-
tors of other vehicles.
Regulate speed to road conditions. Maximum
speed should never exceed 20 m.p.h.
Make sure that SMV emblem, reflectors, and
lights are visible to approaching traffic.
Avoid contact with overhead utility lines. Electri-
cal shock can cause serious injury or death.
SERVICING/
MAINTENANCE
To avoid possible injury, lower the implement
to the ground before servicing.
Properly ballast the tractor before operating.
(See tractor operator’s manual.)
Regulate speed to field conditions, maintain
complete control at all times.
Use extreme care when operating close to
ditches, fences, or on hillsides.
Do not dismount from a moving tractor.
Check box for any debris or excess grain be-
fore each use.
Be sure that all safety shields are in place and
securely latched.
Do not work under an unsupported implement.
Use blocks or jackstands with a load rating equal
to or greater than the weight of the implement
for adequate support.

Safety
DRIVELINE SAFETY
Do not allow children near equipment that is
running or engaged.
Keep all guards and shields in good condition
and properly installed at all times.
Avoid personal attire such as loose fitting cloth-
ing, shoestrings, drawstrings, pants cuffs, long
hair, etc. that can be come entangled in a
rotating driveline.
Do not exceed 1000 rpm PTO speed.
Disengage the PTO, stop the tractor engine, and
remove key from ignition before making inspec-
tions, or performing maintenance and repairs.
Inspect the driveline, quick disconnect, overload
shear-bolt limiter or clutch, and shielding often.
Repair immediately. Use replacement parts and
attaching hardware equivalent to the original
equipment. Do not alter the original design of
the driveline.
Avoid excessively long hardware or exposed
and protruding parts which can snag and cause
entanglement.
Lubricate the driveline as recommended in the
MAINTENANCE section.
Keep hoses, wiring, ropes, etc. from dangling
too close to the driveline.
Install driveline and shields according to rec-
ommended lengths and attaching methods with
recommended hardware. The driveline shield
should rotate independently a full rotation and
telescope freely. The retaining chain must be
secured to the implement safety shield.
Attach offset drawbar hitch end in the down
position and use a recommended hitch pin with
a low head so that no interference occurs with
driveline during operation on uneven or terraced
terrain.
Be careful not to hit the driveline with tractor
tires when turning.
Due to variances in tractor drawbar design and
operating position, it is critical that proper
extended and collapsed lengths of the tele-
scoping PTO shaft be verified before first
operation. If the extended length of the PTO
shaft is not sufficient, it may become uncoupled
in operation and cause serious injury or death
from contact with uncontrolled flailing of PTO
shaft assembly components. Refer to the MAIN-
TENANCE section of this manual for detailed
instructions.

Operation
CAUTION! ALWAYS USE TRANSPORT
CHAIN WHEN TRANSPORTING IMPLE-
MENTS. FAILURE TO USE A TRANSPORT
CHAIN COULD CAUSE PERSONAL INJURY
IF CART BECOMES DISENGAGED.
Always use intermediate chain support when
connecting grain cart directly to a tractor. DO
NOT use the intermediate chain support as
the chain attaching point. Fig. 6 shows how
the transport chain must be installed between
tractor and grain cart.
Transport chain should have a minimum rat-
ing equal to the gross weight of implement
and all attachments. Use only ASAE approved
chains. Allow no more slack in chain than
necessary to permit turning.
CAUTION! REPLACE TRANSPORT
CHAIN IF ANY LINK OR END FITTING
IS BROKEN, STRETCHED, OR DAMAGED.
DO NOT WELD TRANSPORT CHAIN.
HITCHING TO TRACTOR
DRAWBAR CONNECTION
This cart is intended to be hitched to a trac-
tor drawbar. Do not attempt to hitch to any
other location on the tractor other than the
drawbar.
The cart is equipped standard with a single
tang hitch. A hitch pin between 1-1/2" or 2"
diameter must only be used with a clevis-
type tractor drawbar. An optional hammer
strap is available if your tractor has a single
tang drawbar.
NOTE: The use of a smaller diameter hitch pin
will result in additional clearance between the
hitch and pin. This additional clearance may
cause accelerated pin wear, tractor and cart
hitch wear, along with more pronounced jolting
from the cart during transport operation.
WARNING! DO NOT STAND BE-
TWEEN THE CART AND TRACTOR
WHEN HITCHING. ALWAYS ENGAGE PARK-
ING BRAKE AND STOP ENGINE BEFORE
INSERTING HITCH PIN.
After inserting drawbar pin, secure drawbar
pin with a locking device to help prevent
uncoupling during use.
Use jack to support an empty grain cart,
never a loaded grain cart.....always have a
loaded grain cart hooked to tractor.
IMPORTANT: Mount jack in storage location
indicated after cart is hitched to tractor.

HYDRAULIC CONNECTIONS
IMPORTANT: When coupling hydraulic hoses
to ports on tractor, be sure that coupler ends
are clean of dust, dirt and debris. Failure to do
so could contaminate hydraulic system result-
ing in excessive wear and possible failure.
Clean hydraulic hose couplers before connect-
ing to tractor. For convenience it is recom-
mended to connect the flow door circuit hoses
to tractor implement coupler #1, auger spout
circuit hoses to coupler #2, and attach auger
fold circuit to coupler #3.
This unit is equipped with color bands at-
tached to the hydraulic hoses. This will help
in identifying the hose function and correct
hook up.

ceptacle, an SAE J-560 seven-point socket
can be purchased from your Unverferth dealer
(Part number 92824).
The wiring schematic for this cart, shown in
the maintenance section, complies with ANSI/
ASAE Standard S279.11/SAEJ137. Although
most newer tractors conform to this standard,
many older tractors can have a slightly differ-
ent electrical function than standard. Because
of this, always verify correct electrical function
before using this cart.
OPTIONAL LIGHT MODULE
In some areas, the lights may be required to
flash in the specific pattern described in ASAE
S279.10. In these areas, use the Enhanced
