Row Hopper Planters
The following illustration shows rear cross sections of the seed meter in normal and row-failed conditions.
Normal: Filled Bridging: Inlet Gate Bridging: Seed Inlet Empty Hopper
Inlet is filled to hopper.
Seeds move down slowly
singulated by the meter.
A bridge at the seed inlet
gate is blocking flow.
Causes may include:

oversize seed

gate setting too low

oversize matter in seed

excessive or sticky seed
treatment

excess meter pressure
Oversize matter in seed has
caused a bridge at the top
of the inlet. Causes may
include:

oversize seed

oversize matter in seed

excessive or sticky seed
treatment
No seed arriving from
hopper. Causes may
include:

seed run-out
If hopper is empty, air
back-flow (1) is also
occurring, which can reduce
meter pressurization at
other rows.
