SAFETY RULES

A TTENTION! BECOME ALERT! YOUR SAFETY IS INVOL VED!

Safety is a primary concern in the design and manufacture of our products. Unfortunately , our efforts to provide
safe equipment can be erased by an operator’s single careless act. In addition, hazard control and accident
prevention are dependent upon the awareness, concern, judgement, and proper training of personnel involved in
the operation, transport, maintenance and storage of equipment.

Make certain that the operator(s), prior to operating is instructed in safe and proper use and reviews and
understands the manual(s) pertaining to this machine. Also make certain that the operator(s) reviews and
understands the operator’s manual of the tractor prior to hooking up or operating the grain cart.

Read this manual before you operate this machine. If you do not understand any part of this manual, or need
more information, contact the manufacturer or your authorized dealer .

SAFETY

Understand that your safety and the safety of other persons is measured by how you service, and operate this
machine. Know the positions and functions of all controls before you try to operate them. Make sure to check
all controls in a safe area before starting your work.

The safety information given in this manual does not replace safety codes, federal, state or local laws. Make
certain your machine has the proper equipment as designated by local laws and regulations.

A frequent cause of personal injury or death is from persons falling of f equipment and being run over. Do not
permit persons to ride on this machine.

Travel speeds should be such that complete control and machine stability is maintained at all times. Where
possible, avoid operating near ditches, embankments and holes. Reduce speed when turning, crossing slopes
and rough, slick or muddy surfaces.

Collision of high speed road traffic and slow moving machines can cause personal injury or death. On roads,
use flasher lights according to local laws. Keep slow-moving-vehicle emblem visible. Pull over to let faster
traffic pass.

Hydraulic oil leaking under pressure can penetrate skin and cause infection or other injury .
T o Prevent Personal Injury:

Relieve all pressure, before disconnecting fluid lines.
Before applying pressure, make sure all connections are tight and components are in good condition.
Never use your hand to check for suspected leaks under pressure. Use a piece of cardboard or
wood for this purpose.

If injured by leaking fluid, see you doctor immediately .
When transporting the grain cart, always keep the auger in stow position.
Use care when moving or operating grain cart near electric lines as serious injury or death can result from
contact.
Never adjust, service, clean, or lubricate grain cart until all power is shut off. Keep all safety shields in place.
Keep hands, feet, hair and clothing away from moving parts while unit is in operation.

The service ladder is for service work only . If you must climb into grain tank, be certain that all power is shut off
and then use extreme caution when climbing into grain cart.

Make sure that everyone is clear of equipment before applying power or moving the machine.
Make sure that the grain cart is fastened securely to the tractor by using a high strength hitch pin, clip and

safety chains. Make sure that the grain cart hitch properly matches the hitch type of the tractor. Use a single
prong (spade) grain cart hitch with a double prong (clevis) tractor hitch. Use a double prong (clevis) grain cart
hitch with a single prong (spade) tractor hitch.

Before filling the grain cart, make certain that no one is inside the grain tank. Never allow children or anyone in,
near, or on the grain cart during transport or during loading and unloading of grain. Be aware that moving grain
is dangerous and can cause entrapment, resulting in severe injury or death by suffocation.

Never operate the auger system with anyone inside of the grain tank. Hands, feet, hair, and clothing can fit
through the openings in and around the grate. Contact with the auger can cause severe injury or death. Make
certain that all power is shut off before service work is performed.

Before unhooking the grain cart from the tractor, be sure to properly block the wheels to prevent the cart from
moving.

INITIAL OPERA TION/MAINTENANCE

BE CERT AIN THA T ALL POWER IS SHUT OFF BEFORE SER VICING THE GRAIN CART .

Before the grain cart is put into service:
Have the safety instructions been read and clearly understood by the operator(s) of this machine?

Has the gearbox been properly filled with EP-80-90 gearbox lubricant?
Have all nuts, bolts, bearings, and braces been properly fastened?
IMPORTANT: Has the slip clutch on the PTO been serviced? If the slip clutch is left unchecked, damage to

the power-take-off and drive shaft may result. Before using the grain cart, loosen the bolts around the slip
clutch. Make sure that the friction plates turn free of each other and are not corroded together. Retighten the
tension bolts. Run the auger system EMPTY and check for proper engagement of the slip clutch.

Check the PTO overlap length. Overlap length may vary depending on tractor model. Try to obtain the
greatest possible overlap without bottoming out in the maximum operating condition. T oo much overlap may
cause PTO to bottom out and damage driveline. See OPERATING INSTRUCTIONS for recommended
overlap.

Are all bearings on the drive line properly greased? Are all set screws in the bearings and U-Joint s tight? Has
the power-take off been properly greased at all points including cross bearings? Has the universal joint at the
gearbox been greased?

Has the hanger bushing assembly at the auger hinge been greased and have all grease points at the hinge area
been greased?

TIRE PRESSURE - Are the tires properly inflated? The following is to be used as a general guide for tire
inflation for cyclic use. Figures can vary depending on specific brand of tire used. It is important that tires
are inspected before and after unit is loaded. S tart with the minimum pressure indicated. The tire should
stand up with no side wall buckling or distress as tire rolls. Do Not Exceed Maximum Recommended Tire

Pressure.

Tire Size Pressure

23.1 x 26 38 psi

24.5 x 32 38 psi

30.5 x 32 33 psi

35.5 x 32 32-42 psi
900/60-32 35-45 psi

18.4 x 38 37 psi

20.8 x 38 35-40 psi

20.8 x 42 37 psi

WHEEL NUTS - Are the wheel nuts properly fastened (torque to 490 Lbs.-Ft. for standard 22 MM wheel studs
and nuts)? They should be checked after each load during initial operation of the cart and then after
every 10 hours of use. Failure to do so may damage wheel nut seats. Once seats are damaged, it will
become impossible to keep nuts tight.

The drawing shows the proper ways of mounting the wheels using Budd-type nuts. The
wheels supplied with your Grain Cart have straight holes and the Budd nuts will be mounted
according to Figure 1. Wheels that are improperly installed on the grain cart, resulting in
product failure, will nullify warranty and shift the burden of liability to the owner/operator of
the equipment. We suggest that you inspect your wheel nuts to make sure that they are
properly installed. Also, check the wheel nut s on a regular basis to ensure they are tight.

VERY IMPORT ANT:

Under no circumstances is it
recommended to tow a loaded grain
cart in excess of 8 m.p.h.

LIGHTING AND SAFETY DECALS - Are the rear, amber extremity lights properly positioned? Extend light s
within 16” of the left and right extremities of the grain cart. Is a SMV Emblem attached to the grain cart?

Are the lights working properly? Are all reflective decals clean and visible? Are they positioned correctly?

OPERA TING INSTRUCTIONS

BE CERT AIN THAT ALL POWER IS SHUT OFF WHEN HOOKING UP TO TRACTOR OR CONNECTING
HYDRAULIC LINES TO TRACTOR.

Preparing the Grain Cart for Use (see tractor recommendation for grain cart model below):

Model 1075-18R, 1075-22R, 1050-18 or 1050-22 Grain Cart requires a 4WD tractor.

IMPORTANT: Do NOT pull loaded grain cart on highway. For incidental highway travel,

observe the section below.
Tow Loads Safely

Stopping dist ance increases with speed and weight of towed loads, and on slopes. T owed loads with or without
brakes that are too heavy for the tractor or are towed too fast can cause loss of control. Consider the total
weight of the equipment and its load.

Observe these recommended maximum road speeds, or local speed limits which may be lower:

Road Travel (grain cart empty) - Do not travel more than 32 km/h (20 mph) and do not tow

loads more than 1.5 times the tractor weight.

Ensure the load does not exceed the recommended weight ratio. Use additional caution when towing

loads under adverse surface conditions, when turning, and on inclines.

WARNING: For greater stability in uneven or steep terrain, position wheels at the furthest out

axle setting.
