WHEEL NUTS
Check ALL wheel nuts for correct torque setting. (5/8”-350 Ft-Lbs, 3/4”-500 Ft-Lbs, 22MM-
600 Ft-Lbs) Tighten as needed. Re-Check wheel nut torque settings during initial break in
period (during 1st, 2nd , 3rd loads, etc.), then periodically afterwards (every 10 hours of
use for rst 40 hours). Keep checking wheel nut settings until wheel nuts do not loosen.
If wheel nuts loosen and damage the surface of the wheel center, it will be impossible to
keep them tight. Failure to keep the wheel nuts tight could cause considerable damage to
the grain cart and surrounding. It is the Dealer’s responsibility to have wheel nuts torqued
to specication before delivery. Damage caused by failure to keep the wheel nuts tight is
not warrantable.
HITCH
Determine the hitch style of cart to be compatible with tractor. Tractor with hammer strap
(clevis type) should be used with grain carts equipped with a single prong (spade) hitch.
Tractors equipped with a single prong hitch (no hammer strap) should be used with grain
carts equipped with a double prong (clevis) 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.
POWER TAKE-OFF
Check for adequate clearance between telescoping PTO and tractor hitch. Suggested clear-
ance is 7 inches.
Check telescoping PTO for adequate extension. With the tractor hitched to the cart on at
level ground, the PTO should have approximately 10 inches extended from the collapsed
(shortest) length.
If equipped with a yellow Comer PTO, check the PTO slip clutch for correct adjustment for
all grain carts equipped with an 18”, 20”and 22” diameter auger. Standard spring length for
18” auger carts is 1-5/16” (overall spring length only, excluding the nut). For carts with 20”
and 22” diameter augers, tighten overall spring length to 1-1/4”. *All black Weasler clutches
are not adjustable.
HYDRAULIC CYLINDERS AND HOSES
Run all functions of the hydraulic cylinders and inspect ttings and seals for leakage. (use
cardboard or wood to check for hydraulic leaks)

Dealer Pre-Delivery Instructions Grain Cart
UPPER AND LOWER AUGERS
Raise the auger to the unload position. Run the auger from the PTO or optional hydrau-
lic motor. If the top auger is misaligned with the bottom auger, you will hear a ‘bang’ as
the upper auger realigns itself with the lower auger. This is normal as the top auger has
dropped to engage the lower auger. Be sure that the top auger engages the lower auger.
Check bearing at top of auger. Be sure to have approximately 1/8” to 3/16” of an inch gap
under/between top auger bearing. Some models have bearings inside and some models
have bearings outside of upper auger housing. If there is no gap under the bearing, or the
gap is greater than 1/8” to 3/16”, the bearing needs adjusted. See the Operator’s Manual for
instructions on how to adjust the Upper Auger Assembly.
GEARBOX
Check the gearbox oil level. The gearbox should be half full of oil. To check, remove the ll
plug, insert a “dipstick” (large plastic cable tie or similar) into the ll hole until it reaches the
bottom. Mark the dipstick at the ll hole. Oil should be half way on the dipstick. Grain carts
with 14” to 20” diameter augers have gearboxes that require 24 ounces of uid. Grain carts
with 22” diameter augers have gearboxes that require 96 ounces of uid. Add 80/90 weight
gear lube as necessary.
LIGHTING & SAFETY FEATURES
Check the tractor lighting system for functions. Plug the grain cart wire harness into the
tractor receptacle and check the cart lighting for correct functions. Note: The auger spout
light is activated through a mercury switch located at the harness connection under the
discharge spout. The auger spout light should automatically turn on when the auger is in
the unload position, and turn o when the auger is returned to the storage position. If the
auger spout light does not turn on or shut o properly, the mercury switch may need repo-
sitioned.
Check that the safety chains are properly installed. Use bolt-torque chart listed in owners
manual for correct torque value.
TIRES
All tires need to be inated to the specied air pressure given in the owners manual.

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 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 lling 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 suocation.
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. Make certain that all power is shut o before service
work is performed.

Initial Operation & 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 EP-80-90 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”. Dierent 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 drive line properly greased? Are all set screws in the bearings and U-joints tight? Has
the power-take-o 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 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

Operation Instructions
BE CERTAIN THAT ALL POWER IS SHUT OFF WHEN HOOKING UP TO TRACTOR OR CONNECTING HYDRAULIC LINES TO
TRACTOR.
Preparing the Grain Cart for Use: Model 812 and 24t-1 requires a 150+ HP tractor. Models 1012, 1112, 1122, and 31t-1
requires a 225+ HP tractor. Models 1222, and 1312 requires a 250+ HP tractor. Models 1412 and 1522 require a 300+ HP tractor.
IMPORTANT: Do NOT pull a loaded grain cart on highway. For incidental highway travel, observe the section below.
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 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/hr (20 mph) and do not tow loads more than 1.5 times the
pulling unit’s 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 on uneven or steep terrain, position non-scale wheel spindles at the furthest out setting.
IMPORTANT:
1) Connect grain cart hitch to tractor drawbar using a good quality hitch pin. Attach the safety chain to the tractor and through one
chain loop provided on either side of the grain cart frame as shown. Make sure the grain cart hitch properly matches the hitch of
the tractor. Use a single prong (spade) grain cart hitch with a tractor double prong (clevis) hitch. Use a double prong (clevis) grain
cart hitch with a single prong (spade) tractor hitch.
Safety Chain User Instruction
a) Secure the safety chain by looping it around the each side of the grain cart as shown and
connecting to the towing machine’s attaching bar.
b) Do Not allow any more slack than necessary for articulation.
c) Do Not use any intermediate support as the attaching point.
d) Store the safety chain by securing it around the main axle A-frame of the grain cart.
e) Replace the safety chain if one or more links or end ttings are broken, stretched or otherwise
damaged or deformed.
2) Attach the power-take-o shaft to the tractor. The PTO must have at least 10”of engagement. Check tractor drawbar for clearance
and length and adjust if necessary. Make sure the PTO does not bottom out when making sharp turns as it may bend the drive
shaft.
3) Make sure the jack stand is removed from the lower support position before the cart is moved. Never use the jack to support
a loaded grain cart.
4) Be sure that no debris or foreign objects are in the grain cart.
VERY IMPORTANT: Under no circumstance is it recommended to tow a loaded grain cart in excess of 8 mph.
WHEEL NUTS: Are the wheel nuts properly fastened? Torque to 700 Lbs.-Ft. for standard 22mm wheel studs and nuts. Torque
to 500 Lbs.-Ft. for 3/4” wheel studs and nuts. Torque to 350 Lbs.-Ft. for 5/8” wheel studs and nuts. Wheel studs and nuts
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 studs and nuts. Once the seats are damaged, it will become impossible to keep the lug nuts tight.
The drawing shows the proper way to mount 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. We recommend you inspect your wheel nuts to make sure they
are properly installed. Also, check the wheel nuts on a regular basis to ensure they are tight.
LIGHTING AND SAFETY DECALS: Are the rear, amber extremity lights properly positioned? Extend the lights within 16” (40,6cm)
of the left and right extremities of the grain cart. Is an SMV Emblem attached to the rear of the grain cart?
Are the lights working properly? Are all lights and reective decals clean, visible and properly placed?

Operation Instructions
CAUTION
• Do NOT operate the grain cart before reading and understanding the Operator’s Manual and ALL danger, warning and
caution signs.
• Be sure that a Slow-Moving-Vehicle emblem is attached to the rear of the grain cart.
• Never exceed 1,000 rpm on the PTO and driveline system.
• Never fold or extend the auger until the PTO has come to a complete stop.
• Never ll the grain cart unless the gate indicator is in the closed position.
• Never allow foreign object (shovels, etc.) to be placed inside the grain cart.
• Never engage the lugs and drive dogs on the augers when the system is moving at a high rate of speed.
• Never perform maintenance work or service the grain cart with the tractor running.
5) Attach the hydraulic lines to the tractor. Two hydraulic lines (green band) operate the inside gate mechanism. Connect these
lines to one service outlet on the tractor. Two hydraulic lines (yellow band) operate the folding mechanism of the auger. Connect
these lines to a second service outlet on the tractor. The remaining two hydraulic lines (red band) operate the hydraulic ow control
spout located at the end of the upper auger. Connect these lines to a third service outlet on the tractor. Make sure the air is bled
from the hydraulic cylinders and hoses.
6) Run the auger system EMPTY before loading grain into the tank for actual use. Make certain that the slip clutch is operating and
that the upper and lower augers are properly engaged.
7) Connect the lighting 7-prong connector end on the main wiring harness to the tractor electrical outlet. Make sure that all asher
and turn indicator lights are working properly before incidental highway travel.
1) With the gate indicator in the closed position, ll the tank with grain.
2) With the PTO disengaged, fold the discharge auger to the upright position.
3) IMPORTANT: After the upper auger is in the upright position, be sure to start the PTO at a SLOW RATE OF SPEED until the lugs
on the upper auger engage the drive dog on the bottom auger. Failure to follow this procedure may cause extensive damage to
both the drive dog and the drive line.
4) Increase the PTO speed and slowly open the inside tank gate until the gate indicator rod located above the upper auger is
halfway between the Open and Closed position. When grain begins owing from the discharge auger, continue to open the gate
to obtain the desired unload rate.
5) To stop unloading grain, return the inside tank gate to the closed position and allow the material inside the auger to unload.
For complete cleanout, gradually close the inside tank gate. Once the grain has ceased to ow, disengage the PTO and allow its
rotation to come to a complete stop. The upper auger is now ready to be returned to the stow position. IMPORTANT: Do Not Pull
the grain cart through the eld with the unloading auger in the upright position. Failure to return the auger to the lowered stow
position may damage the hinge and greatly reduce the life of the auger system.
WARNING
BE CERTAIN ALL POWER IS SHUT OFF WHEN SERVICING THE GRAIN CART
• Repack the bearings in the hub assembly once a year or as needed. Use a good quality LS EP2 Severe Duty, High Shock Load,
Lithium based Grease. Also check the seal for wear and replace if necessary.
• Check the grain cart periodically for cracks in welds and for other structural damage. Have cracked welds xed immediately.
Failure to do so could result in extensive damage to the grain cart and greatly reduce the life of the cart.
• Lubricate the slides on the clean-out door.
• Check all hydraulic hoses for wear and replace as necessary.
• Make sure all tires are properly inated. See INITIAL OPERATION AND MAINTENANCE in the Owner’s Manual for recommended
instructions for tire pressure. It is important that tires are inspected before and after unit loaded.
• Check PTO for wear of plates in the slip clutch. Replace if needed.
• Make sure that all guards and shields are in place before operating the grain cart.

Lubrication Service Schedule
IMPORTANT: Your grain cart has grease ttings at all critical points. These should be serviced before the grain cart is
put into operation.
WARNING: BE CERTAIN THAT ALL POWER IS SHUT OFF BEFORE SERVICING THE GRAIN CART
GEARBOX: Gearbox lubricant has been added to the gearbox
during nal assembly. Recheck the lubricant level before initial
operation of the grain cart, then periodically according to use. An
inspection plug is located in the center of the top of the gearbox
mount plate. To check the uid level, remove the vented inspection
plug and drain plug at the bottom of the gearbox. Drain the
lubricant. Return the drain plug and rell the gearbox with 24
ounces (0,71 liters) of gearbox lubricant. The gearbox is properly
lled when half full of lubricant. DO NOT OVERFILL. Use EP 80-90
gearbox lubricant or equivalent.
SPRING LOADED UPPER AUGER BEARING: Service the
grease tting on the upper auger bearing (located at the top
end of the upper auger assembly) after every 8 hours of use.
Lubricate the springs and retaining bolts on the bearing before
prolonged storage of the grain cart.
AUGER FOLDING MECHANISM: One grease tting is located on
the pivot pin of the folding auger. This tting should be serviced
after every 8 hours of use. Service the grease tting on the hanger
bushing assembly (top end of the lower auger assembly) after every
8 hours of use or as needed.
PTO & DRIVELINE: The grease ttings on the
PTO should be serviced after every 8 hours of use.
Service the grease ttings on each of the drive
bearings and also the universal joint after every 8
hours of use.

Removing Dirt from the Restrictors on the Hydraulic Cylinder
After the rst hour of operation, the slip-disc clutch on the PTO should be checked for overheating. After the rst hour, the slip-
disc clutch should be checked weekly or anytime there is excessive slippage of the friction discs. The slip-disc clutch should be
checked for moisture, which could cause corrosion on the drive plates. If the grain cart has been idle for an extended period of
time, or in wet weather, check to make sure that the friction lining plates are not rusted or corroded together. The friction lining
plates are 1/8”(0,32cm) thick new. They should be replaced after 1/32” (0,08cm) of wear to ensure proper operation.
IMPORTANT: If the machine has never been used or has not been operated for one (1) season, the following is recommended.
When the grain cart has been idle for an extended period of time, it is important to check the slip-disc clutch to make sure that it
will slip when an obstacle or load heavier than the torque setting is encountered. Use the following procedure to make certain
that the slip-clutch will slip and give the overload protection required.
1. Loosen the nut on the springs until the springs can rotate, yet remain secure on the bolts.
2. Place a mark on the outer plate of the slip-disc clutch.
3. Securely attach the PTO and the grain cart to the tractor and start the tractor.
4. Engage the PTO for several seconds then quickly disengage it.
5. Turn the tractor o.
6. The friction lining plates should have been broken loose or “slipped”. Check the marks placed on the outer plates of the slip-
disc clutch. If the marks are aligned, the friction plates are not working properly.
7. Adjust the nuts on the springs to set the spring compression height to 1.27 inches (3,23cm).
WARNING
MAKE SURE THAT ALL POWER IS SHUT OFF BEFORE ADJUSTING THE FLIGHTING ASSEMBLY.
If the drive-dog and hanger assembly are becoming excessively hot during unloading, the lower ighting and/or hanger may need
adjusting. The hanger bushing assembly has elongated holes where it attaches to the outer tube assembly. Loosen the two 3/8”
bolts on the hanger bushing assembly. Adjust the hanger either up or down and vertically center it between the ighting and drive
dog. Re-tighten the bolts. Make certain that the ighting center and drive-dogs do not rub the hanger bushing assembly, causing
them to become hot.
If the hanger can no longer be adjusted by moving it up or down on the elongated holes, both the hanger bushing assembly and
the lower ighting will have to be removed. After removing them from the tube assembly, place a shim [between 1/8” (0,32cm) to
3/16” (0,48cm) thick] where the gearbox and the spline coupler (welded to the lower ighting). Replace the lower ighting and
reattach the hanger to the tube assembly. Readjust the hanger assembly. NOTE: The bottom of the lower ighting is not attached
to the gearbox with any bolts or set screws but may be‘frozen’ fast. Be careful when removing the lower ighting from the gearbox.
For easier removal of the lower ighting, keep the gearbox at the bottom intact, remove the 2 3/8” bolts from the hanger bushing
assembly and pull the lower ighting o of the gearbox.
After adjusting the lower ighting, move the upper auger to the unload position and check the upper ighting for readjustment.
WARNING
MAKE SURE THAT ALL POWER IS SHUT OFF AND THE UPPER AUGER TUBE IS IN THE DOWN POSITION BEFORE
REMOVING THE RESTRICTORS
Remove restrictors from the 90 degree street elbow on the hydraulic cylinder. Remove dirt from the tting to allow hydraulic
oil to ow through the restrictor. Reattach the restrictor to the street elbow. Use teon sealant tape or equivalent on the
threads of the restrictor before re-attaching.
If the restrictor continues to plug with dirt, replace the restrictor or lter the hydraulic oil in your system.

Adjusting the Upper Flighting
WARNING
MAKE SURE ALL POWER IS SHUT OFF BEFORE ADJUSTING THE FLIGHTING ASSEMBLY
If the upper and lower augers to do not properly separate during the unfolding sequence, the upper ighting may need adjusting.
Before making adjustment to the upper ighting, check to see if the lugs and drive dogs on the auger assemblies are locking
together. If they are not locked together, check to see if dirt is in the restrictor or if a faulty check valve on the hydraulic cylinder
used to raise and lower the upper auger assembly may be causing the problem. If dirt is in the restrictor, see “Removing Dirt From
Restrictors On Hydraulic Cylinders” below.
Fold the upper tube assembly into the upright position. Position the upper ighting in the engaged position with the lower ighting.
Locate the four-hole ange bearing on the top of the upper auger tube housing. With the upper ighting in the engaged position,
check the spacing between the upper bearing and the upper tube housing. There must be an 1/8” (0,32cm) space between the
base of the four-hole ange bearing and the upper tube housing. If there is NOT a space between the bearing and the upper tube
housing, or if there is more than 1/8” (0,32cm) space, the upper ighting will need to be adjusted. To adjust the upper ighting,
loosen the 1 1/4” hex nuts both above and below the four-hole ange bearing. Move the 1 1/4” hex nuts up or down the threaded
shaft on the top of the auger ighting shaft until the bearing moves to approximately 1/8” (0,32cm) above the base of the upper
tube housing. When the four-hole ange bearing is properly located, tighten both 1 1/4” hex nuts together to secure the bearing
position.
If the upper and lower ighting still does not separate properly during the folding sequence, a small bevel may need to be removed
from the inside of the lugs where they engage the drive dogs on the auger assemblies. Grind approximately 1/8” (0,32cm) from the
corner of the lugs where they touch against the drive dogs.
IMPORTANT: When the grain cart is not going to be used for a period of time, store the cart in a dry, protected place. Leaving
your grain cart outside, open to the weather will shorten it’s life.
Follow the procedure below when your grain cart is placed in storage for periods up to six months.
1. Cover electronic monitor (if equipped) with plastic before washing the grain cart. Wash or clean and completely lubricate
the grain cart. See the lubrication service section in this manual.
2. Remove all grain from inside the grain tank, auger tube assemblies, and at the clean-out door.
3. Check the gearbox oil and replace with new EP 80-90 gearbox lubricant or equivalent if necessary.
4. 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.
5. Retract all hydraulic cylinders to prevent the piston rods from rusting.
6. If the grain cart is equipped with an electronic weigh system, fully charge the battery to prevent freezing. Disconnect the
negative (-) ground cable at the battery to prevent possible discharge.
7. Clean the tires before storage. Inate the tires at regular intervals.
8. Open the clean-out door at the base of the grain tank.
9. Loosen the Slip Clutch Tension Bolts.
1. Check the gearbox to make sure it has the appropriate amount of oil.
2. If equipped with an electronic scale system, check the battery and make sure that it is fully charged. Reconnect the negative
(-) cable.
3. Inate the tires to the correct operating pressure.
4. Close the clean out door at the base of the grain tank.
5. Make sure all safety shields are in the proper position.
6. Tighten the Slip Clutch Bolts on the PTO until the spring length is 1.27 inches (3,23cm).
