Standard 5/8” wheel bolts should be tightened to torque 350 Ft.-Lbs. During initial operation of the gravity wagon and then checked
for proper torque 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 correct tire pressure for the 165-225 x135 tire is 85 PSI.

Safety Rules
ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
• Safety is a primary concern in the design and manufacture of our products. Unfortunately, our eorts 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, judgment, 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.
• 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 RULES
1. Understand that your safety and the safety of other persons
are 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.
2. 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.
3. A frequent cause of personal injury or death is from persons falling
o equipment and being run over. Do not permit persons to ride on
this machine.
4. 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.
5. Collision of high speed road trac and slow moving machines can
cause personal injury or death. On roads, use asher lights according
to local laws. Keep slow-moving-vehicle emblem visible. Pull over to let
faster trac pass.
6. Make sure that the implement is fastened securely to the tractor
/truck by using the proper hitch pin, clip and safety chains.
9. IMPORTANT: Use caution when transporting. Be alert of the
transport unit’s overall width when approaching obstacles, such as
post signs and poles, along the road. Check the transport width of
the unit to ensure clearance before entering bridges.
10. Do not allow anyone to stand between tongue or hitch and
towing vehicle when backing up.
11. Choose the most level route possible when transporting across
elds.
12. Never adjust, service, clean, or lubricate gravity box until all
power is shut o.
13. Keep all safety shields in place. Keep hands, feet, hair, and clothing
away from the moving parts while the unit is in operation.
14. The service ladder is for service work only. If you must climb into
the grain tank, be certain that all power is shut o and then use
extreme caution when climbing into the grain tank. Never allow
anyone in, near or on the gravity box during transporting or unloading grain. Moving grain is dangerous and can cause entrapment,
resulting in severe injury or death by suocation.
15. Make sure that everyone is clear of equipment before applying
power or moving the machine.
7. Before unhooking the implement from the towing unit, be sure
to properly block the wheels to prevent the implement from moving.
8. Never overload the wagon. Overloading the wagon is dangerous
and can cause extensive damage. Never add more sideboards to the
gravity box than what is recomended, as the box is not designed to
carry the additional weight. Do NOT exceed speeds in excess of 20 MPH.
Rim, hubs and bearings are designed for heavy loads at slow speeds.
Also be sure slow moving vehicle emblem is attached to the rear of the
wagon.
14. COMPLY WITH ALL SAFETY WARNINGS AND CAUTIONS IN
THIS MANUAL AND IN THE COMBINE OPERATORS MANUAL
WARNING: BE SURE ALL LIGHTS ARE WORKING PROPERLY
BEFORE HIGHWAY TRAVEL.

Initial Operation / Maintenance
WARNING BE CERTAIN THAT ALL POWER IS SHUT OFF BEFORE SERVICING THE GRAVITY BOX.
Before the gravity box is put into service:
Has the track assembly (opens door) been lubricated for less wear on the sprocket and track and for easier door operation.
Has the SMV (Slow Moving Vehicle) Emblem been positioned with a point of the triangle upward and as near to the rear and
centered or as near to the left of center of the unit as practicable? Is it located two to ten feet above the ground measured
from the lower edge of the emblem?
Has the gravity box been properly attached to the running gear? If no rocking bolster is used, bolt all four corners (use 1/2”
bolts provided) of the gravity box runners to the running gear. (If the box is used in rough terrain, bolt a minimum of two
corners and chain (or cable) the remaining corners to allow more box exibility.
Have all braces, bolts, nuts, lug bolts, and lug nuts been checked to ensure that they are properly fastened?
NOTE: The proper torque for the wheel lug nuts is 350 ft lbs.
Have the safety instructions been read and clearly understood by the operator(s) of this machine.
Do the lights work properly? Are all reective decals clean and visible? Are they positioned correctly?
Are the tires properly inated? The following is to be used as a general guide for tire ination for cyclic use. Figures can vary
depending on specic brand of tire used. It is important that tires are inspected before and after the unit is loaded. The
tire should stand up with no side wall buckling or distress as the tire rolls. Do Not Exceed The Tire Pressure Indicated
Below:
Tire Size psi
BRAKING SYSTEM REQUIREMENTS
WARNING Tow Loads Safely
Stopping distance increases with speed and weight of towed loads, and on slopes. Towed loads with or without brakes that
are too heavy for the tractor or are too fast can cause loss of control. Consider the total weight of the equipment and its load.
For towed equipment WITHOUT brakes, the following is recommended:
Do NOT tow equipment that does not have brakes at speeds over 32 km/h (20 mph); or that, when fully loaded, has a mass
(weight) over 1.5t (3300 lb) and more than 1.5 times the mass (weight) of the towing unit.
For towed equipment WITH brakes, the following is recommended:
Do NOT tow equipment that has brakes at speeds over 40 km/h (25 mph); or that, when fully loaded, has a mass (weight) more
that 4.5 times the mass (weight) of the towing unit.
Ensure the load does not exceed the recommended weight ratio. Use additional caution when towing loads under adverse
conditions, when turning and on inclines.
WARNING
Before lling the gravity box, make certain that no one is inside the grain tank. Never allow children or anyone in, near, or on
the gravity box during transport or during loading or unloading of grain. Be aware that moving grain is dangerous and can
cause entrapment, resulting in severe injury or death by suocation.
After hauling corrosive materials such as fertilizers, be sure to wash out the grain tank to prevent premature rusting. Bare
spots on metal should be primer coated before applying the outer surface paint.
385/65R22.5 70
425/65R22.5 85
Check the box periodically for cracks in welds and for other structural damage. Have cracked welds fixed immediately.
Failure to do so could result in extensive damage and greatly reduce the life of the gravity box.
