Problem
Cause
Solution
Sweep stops travelling around
the bin
Sweep isn’t adjusted correctly
and is hitting a high spot on the
aeration floor
Sweep drive wheel isn’t func-
tioning properly (stripped gears,
sheared bolts, loose bearing
that holds sprocket in place
etc…)
Drive wheel rubber is worn
down
Obstruction in sweep
Adjust sweep in 2 places: Drive
wheel and upper gearbox plate
Ensure all bolts are in place and
tightened, sprocket and gears
are in place and not stripped,
bearing is tightened.
Replace rubber drive wheel or
rubber treads
Remove obstruction
Poor product flow from sweep
Sweep is touching floor or drive
wheel is not adjusted properly
Obstruction in sweep
Damaged or bent flighting
Adjust sweep and ensure drive
wheel is in working condition
Remove obstruction
Repair or bend flighting back to
original shape. If this doesn’t
work, replace flighting
Underfloor auger is unable to
move the grain that the sweep
is dumping into the center hop-
per
Obstruction in center hopper
Intermediate hoppers are open,
flooding the underfloor auger
Flighting is not timed correctly
on the underfloor auger
Remove obstruction
Close intermediate hoppers
Pull out underfloor flighting,
ensure that it is timed correctly
(flighting must make a continu
-
ous spiral)
Underfloor system stops when
moving product
Electric motor belts are not tight
enough
Electric motor is not large
enough to power entire system
Obstruction in underfloor auger
Tighten belts
Replace electric motor with a
larger model
Remove obstruction
Grain is flowing over backboard
of sweep
This is normal, and the grain
will be swept up on the second
pass of the sweep
No solution needed. Part of
normal operation
