Bolt Torque Chart
TIGHTENING WHEEL NUTS: Standard 3/4” wheel studs and nuts should be tightened to torque 400 ft-lbs. During initial operation of
the grain cart 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.
Always tighten hardware to these values unless a dierent torque or tightening procedure is listed for specic application. Fasteners must
always be replaced with the same grade as specied in the manual parts list. Always use the proper tool for tightening hardware. Make
sure fastener threads are clean and you start thread engagement properly. Use these values when tightening all bolts and nuts with
the exception of wheel nuts.

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 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 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
J&M Mfg. Co., Inc. 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 o 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 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.
Hydraulic oil leaking under pressure can penetrate skin and cause infection or other injury. To prevent personal injury,
• Relieve all pressure, before disconnecting uid 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 uid, see your doctor immediately.
When transporting the grain cart, always keep the auger in the stow position.
Use care when moving of operating the grain cart near electric lines as serious injury or death can result from contact.
Never adjust, service, clean, or lubricate the grain cart until all power is shut o. Keep all safety shields in place. Keep hands, feet, hair
and clothing away from moving parts while the grain cart is in operation.
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 cart.
Make sure that everyone is clear of equipment before applying power or moving the machine.
Make sure the grain cart is fastened securely to the tractor using a high strength hitch pin, clip and safety chains. Make sure 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. Be sure the tractor pin is at least 1/4”smaller
in diameter than the pin hole in the grain cart hitch to ensure enough free movement when traversing through uneven terrain.
Before lling the grain cart, make certain 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 suocation.
Never operate the auger system with anyone inside the grain tank. Hands, feet, hair and clothing can t through the openings in and
around the grate. Contact with the auger can cause severe injury or death. Ensure all power is shut o before service work is performed.
Before unhooking the grain cart from the tractor, be sure the jack stand is properly mounted and in place and the wheels are properly
blocked to prevent the cart from moving.

Initial Operation and Maintenance
WARNING
BE CERTAIN THAT ALL POWER IS SHUT OFF BEFORE SERVICING 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 lled with SAE 80W-90 gearbox lubricant?
• Have all nuts, bolts, bearings and braces been properly fastened?
• Has the PTO been checked for proper overlap?
IMPORTANT: Has the slip clutch on the PTO been serviced? If the slip clutch is left unchecked, damages to the power-take-o and drive
shaft may result. Before using the grain cart, loosen the bolts around the slip clutch. Make sure the friction plates turn free of each other
and are not corroded together. Re-tighten the tension bolts. Run the auger system EMPTY and check for proper engagement of the slip
clutch.
CHECK PTO OVERLAP LENGTH. Overlap length may vary depending on the tractor model and hitch setting. Try to obtain the greatest
possible overlap without bottoming out in the extreme operating conditions. Too much overlap may cause the PTO to bottom out and
damage the driveline. Not enough overlap may cause the PTO front and back halves to separate. From the fully compressed (shortest)
length the PTO should be telescoped (extended) between 10”and 22”. Dierent PTO lengths may need to be purchased to accommodate
your terrain. A 4”shorter or a 10”longer PTO can be ordered through your dealer from J&M Manufacturing.
GREASE BEARINGS: Are all bearings on the driveline properly greased? Are all set screws in the bearings and U-joints tight? Has the
PTO shaft been properly greased at all points including the cross bearings? Has the universal joint at the gearbox been greased? Have all
grease points at the auger hinge area, including the hanger bushing assembly been greased?
TIRE PRESSURE: Are the tires 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:
