Problem Cause Solution Page(s)
No Load Inlet valve and/or 735 gallon
tank discharge valve closed Open valve(s).
32 or 33
Insufficient pressure at
source Elevate source or use pump.
19
Inlet filter completely clogged Clean filter. 27
In cold weather, inlet plumb-
ing may be frozen Move cart to warm space or wait for warmer weather.
Slow Load Inlet filter partially clogged Clean filter. 27
Insufficient pressure at
source Elevate source or use pump.
19
Solids in mix too large for
inlet filter Reconsider using this material. Although you could top-
load it, or replace the 12 mesh filter with a 6 mesh, no
standard orifice plate sizes are apt to be large enough
to pass this material at the row drops.
Tank Level
Lower at
Field Material sloshed out breather
vent in transport Fill tank at field, or to less than half full prior to transport,
and/or drive slower, brake more gently or chose a
smoother route.
Leak due to damaged or
loose hose/fitting Inspect entire cart plumbing system for leaks. Repair as
needed.
No Flow in
Field Pump not yet primed Prime the pump. Otherwise, at low application rates, it
may take some time/distance to clear the air from a
completely dry implement inlet and boom system.
20
One or more valves closed Check that tank discharge, cart outlet and implement
inlet valves are all open.
20
Material depletion Stop and check sight gauge 18
Pump strainer completely
clogged Clean pump strainer. Also check mesh size vs. material
requirements.
27
Pump inoperative Check pump sprockets, chain, range and scale setting.
Check for internal pump failure. For a pump other than
Great Plains ground drive, also check monitor settings,
cable harness, fuses, clutches, etc.
a
Cold weather: material too
viscous for strainer and/or
orifice plates. Material might
be entirely frozen. Wait for warmer weather. Increasing pump strainer
mesh and orifice plate sizes to compensate for cold gel-
ling may produce uneven application rates.
All material dumping at relief
valve Check and adjust the relief valve. If not set too low, ori-
fice size is likely to small for material viscosity or solids.
