Safety Rules
ATTENTION! BECOME ALERT! YOUR SAFETY IS INVOLVED!
Safety is a primary concern in the design and manufacture of our products. Unfortunately, our eorts 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. Also make certain that the operator(s) reviews and understands the operator’s manual of the tow vehicle
prior to hooking up or operating the gravity wagon.
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. COMPLY WITH ALL SAFETY WARNINGS AND CAUTIONS IN THIS MANUAL AND IN THE
COMBINE OPERATOR’S MANUAL
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. 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. Ensure 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 trac 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 trac pass.
6. Fasten the gravity wagon securely to the pulling vehicle using the proper hitch pin, clip, and safety chains.
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. Rims, hubs and bearings are designed for heavy loads at slow speeds. Also ensure slow moving vehicle emblem is attached to the
rear of the wagon.
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 wagon 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 all power is o and use extreme caution.
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 suocation.
15. Make sure that everyone is clear of equipment before applying power or moving the machine.
16. WARNING: BE SURE ALL LIGHTS ARE WORKING PROPERLY BEFORE HIGHWAY TRAVEL.

Initial Operation & Maintenance
Initial Operation
WARNING: Ensure all power is shut o before servicing the gravity wagon.
Before the gravity wagon is put into service, check the following items for safe operation:
• The track assembly for the door has proper lubrication for less wear on the sprocket and track and easier door operation.
• The SMV (Slow Moving Vehicle) sign is 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. The lower edge of the sign should be located 2-10 feet above the ground.
• The gravity wagon is properly attached to the running gear. If no rocking bolster is used, bolt all four corners (use 1/2”bolts
provided) of the gravity wagon 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.
• Check all braces, bolts, nuts, lug bolts, and lug nuts been checked to ensure they are properly fastened. The proper torque for the
wheel lug nuts is 350 ft lbs.
• All operators of this machine have read and clearly understand the safety instructions.
• All lights must work properly. All reective decals are clean, visible, and positioned correctly.
• Tires are properly inated. The following is to be used as a general guide for tire ination for cyclic use. Figures can vary depending
on specic 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:
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 wagon, make certain that no one is inside the grain tank. Never allow children or
anyone in, near, or on the gravity wagon 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 suocation.
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.
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 wagon.

Lubrication
Your gravity wagon has grease ttings at all critical points. These should be serviced before the gravity wagon is put into
operation each season.
HOW TO FLUSH OLD OIL OUT OF THE OIL BATH HUBS
Your gravity wagon is equipped oil bath hubs. Follow these steps to ush the oil bath hubs once per year.
1. Check the hub for leaks and wear. Replace components as necessary.
2. Roll the hub until the ll plug is on top.
3. Drain the hub by removing the cap.
4. After draining the old oil, use light weight motor oil to ush out remaining oil. There is no need to tilt the hub, the oil will ow
through the bearing easily.
5. Replace cap. Torque cap to 30-40 ft-lbs.
6. Replace oil with 80-90WT Sta-Lube from NAPA. This oil has a rust inhibitor additive.
HOW TO ADD OIL TO OIL BATH HUBS
IMPORTANT: Use Napa STA-Lube - GL5 80/90 WT with Rust Inhibitors FL2472 for the Oil Bath Hubs.
1. Use a 3/4”wrench to remove breather plug.
2. Add 80-90WT Sta-Lube oil from NAPA with an oiler hand pump. The recommended oil capacity in the hubs is 8 ounces.
3. Replace breather plug. First hand tighten, then use 3/4” wrench to make a 1/4”of a turn.
Routine Maintenance
WARNING: Ensure all power is shut o before servicing the gravity wagon.
• Check the gravity wagon periodically for cracks in welds and for other structural damage. Fix cracked welds immediately. Failure to
do so could result in extensive damage to the gravity wagon and greatly reduce the life of the unit.
• If equipped with uni-swivel auger, check all hydraulic hoses for wear and replace as necessary.
• Ensure all tires are properly inated. Refer to“Initial Operation & Maintenance” on page 11 for recommended tire pressures. It is
important that tires are inspected before and after unit loaded.
• Ensure all grease ttings have proper lubrication.
• Properly torque all lug nuts to 350 ft-lbs.
Your local, authorized dealer can supply genuine replacement parts. Substitute parts not provided by J&M Manufacturing may not meet
original equipment specications and may be dangerous.
When performing maintenance work, wear sturdy, rough-soled work shoes and protective equipment for eyes, hair, hands, hearing and
head. Follow instructions in this manual to ensure safe and proper maintenance and repair.
Store the gravity wagon in a dry, protected place. Leaving your gravity wagon outside, open to the weather will shorten its life.
Follow the procedure below when your gravity wagon is placed in storage for periods up to six months:
1. Remove all grain from inside the grain tank.
2. Wash or clean and completely lubricate the gravity wagon.
3. Touch up areas where paint may have worn away. Use a good quality primer paint, especially before re-applying graphite paint to the
interior slopes of the grain tank.
4. Clean the tires before storage. Inate the tires at regular intervals.
Storage Preparation

13
Bleeding the Brake Lines
METHOD ONE (requires two people)
1. Close all bleed screws
2. Start with the wheel furthest from the master cylilnder. Slip a transparent bleed hose on the bleeder stem and place the other end of
the hose in a clean container which is partially lled with uid at all times.
3. The rst person depresses the brake plunger SLOWLY. This should take 3-5 seconds. Next, the second person opens the bleed screw.
He then closes the bleed screw BEFORE the rst person SLOWLY releases the plunger. This should again take 3-5 seconds. Continue
process until there is no evidence of air in the bleed hose.
4. Repeat for remaining wheels working from the longest to the shortest distance from the master cylinder. Top o master cylinder as
needed to prevent reintroducing air into the lines.
METHOD TWO (one person)
1. Attach bleed hose to rear wheel as in method one. Open bleed screw. SLOWLY depress plunger (3-5 seconds). Repeat until line is air
free. Close bleed screw. Top o master cylinder as needed to prevent reintroducing air into the lines.
Repeat with remaining wheels.
DANGER: Contamination with dirt, water, petroleum products or other materials may result in brake failure or costly repairs.
Adjusting the Brake Master Cylinder
1. Use a 9/16”wrench to remove the (2) 3/8” x 1” serrated hex head bolts and
shield.
2. Loosen the 1/2”nut on the plunger pin. Use a 3/4” wrench.
3. Rotate the plunger rod to adjust. The braking plunger system should have
approximately a 1/4” of play when adjusted for level road travel. For more
aggressive braking action turn the plunger rod counterclockwise. This will
lengthen the assembly. For less aggressive braking action turn the plunger rod
clockwise. This will shorten the assembly.
DANGER: Do not adjust all the play out of the plunger system. This will
cause the brakes to be activated at all times and overheat the drums,
causing failure.
NOTE: This braking system is designed to assist the pull vehicle in braking,
not to take the place of it.
4. Tighten the 1/2”hex nut to keep plunger rod in place.
5. Put the shield back on and tighten both 3/8” x 1” SF hex bolts.
3/8” x 1” Hex Bolt

Adjusting the Brakes
The brake adjustment nut is located behind a slot at the bottom of the backing plate. Tighten the nut until you cannot rotate the wheel
by hand, then back o the adjustment 18 to 20 notches.
IMPORTANT: When adjusting drum brakes, rotate the wheel and drum in a forward rotation only.

Gravity Wagon Trail Adjustment
• Ensure the tongue bolt is as tight as possible without over restricting the vertical motion of the hitch.
• An extra washer (shown below) can be added if the nut is tightened so far that it runs out of threads before the tongue bolt is as tight as
possible.
• Ensure all tires are properly inated. Refer to“Initial Operation & Maintenance” on page 11 for recommended tire pressures.
• If either of the front tires look to be excessively worn or unevenly worn they should be rotated with a less worn rear tire, if possible.
• Toe the front tires inward 3/16” on front from rim to rim (acceptable range for tired to be toed insward is 1/8” to 1/4”). For directions
on how to adjust the toe-in, follow the steps below.
• Ensure the inner tongue bolt (shown below) is tightened enough to mitigate slop but still allow the inner tongue to slide in and out of
the outer tongue. It is acceptable to see the outer tongue squeezed inward by the inner tongue bolt for a slop-free t.

Adjusting Running Gear Toe-In
1. Position the tongue in the straight and horizontal position. Measure both“L1”locations. Once both locations are the same length, move
to the next step.
2. Measure both“L2”locations. Adjust both tie-rods to ensure both measurements are equal.
3. Measure“L3”and“L4”distances. L3 should be set 3/16”smaller than L4 by adjusting the tie-rods in equal amounts.
4. Measure both“L2”locations again to ensure they are the same. If L2 lengths are dierent, repeat the process.
