J&M 818 - Manual (Page 9)

OPERATING 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 818 Grain Cart requires a 150 hp tractor (minimum).
IMPORTANT: Do NOT pull 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 it’s 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
around the A-frame of the cart 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 no more slack than necessary for articulation (maximum 11 inches)
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 fi ttings are broken, stretched or otherwise
damaged or deformed.
2) Attach the power-take-off shaft to the tractor. The PTO must have at least 12” (0,31m) 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 ban) operate the inside gate mechanism. Connect
these lines to one service outlet on the tractor. Two hydraulic lines (yellow ban) operate the folding mechanism of the
auger. Connect these lines to a second service outlet on the tractor. The remaining two hydraulic lines (red ban) operate
the hydraulic fl 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 fl asher and turn indicator lights are working properly before incidental highway travel.
