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 640 Ft.-Lbs. for standard 22mm wheel studs and nuts. Torque to 400
Ft.-Lbs. for 3/4" 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 reflective decals clean, visible and properly placed?
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 1312 grain carts require a 250+ 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 each side of the grain cart as shown and
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 fittings are broken, stretched or otherwise
2) Attach the power-take-off 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.
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 flow 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.
