Seed Pool Recovery
When a seed meter has been starved of seed, the
back-flow of air through the open gate reduces
delivery air flow. This causes seed delivery to be
slow. If you start or resume planting with an empty
seed pool, the delivery flow may be too low to keep
the meter supplied. The steps below quickly prime
the meter by rebuilding the seed pool.
Normal: Filling Normal: Filled
Delivery Blockage or
Back-flow Starvation
Bridging: Screen Bridging: Gate
Seed pool at the gate
prevents back-flow of
meter pressurization air,
allowing seed to flow
from the delivery
system, filling the inlet
to the top of the air
release screen.
Once the inlet is filled to
the top of the air release
screen, the air flow from
the delivery system is
blocked. No further
seed arrives until
planting reduces the
backlog at the inlet.
No seed is arriving from
the manifold. Air back-
flow (1) is occurring.
Causes may include:
• low fan speed
• seed hose
blockage
• no seed available
• Y-tube closed
• meter never primed
Oversize matter in the
seed has caused a
bridge at the top of the
inlet. Air back-flow (1) is
occurring.
When the bridge is
released, the seed pool
will be insufficient to
prevent back-flow.
A bridge at the gate is
blocking flow. Causes
may include:
• oversize seed
• gate setting too low
• oversize matter in
seed

No action required.
Continue planting.
1. Correct the cause of
the blockage.
2. Perform a one-row
seed pool recovery.
3. Resume planting.
1. Close gate.
2. Disconnect hose at
the meter.
3. Tap on air release
screen and inspect.
4. Check seed pool for
foreign matter.
5. Perform a one-row
seed pool recovery.
6. Resume planting.
1. If the gate is at
suggested opening,
increase one notch.
2. Check the seed pool
for foreign matter.
3. Resume planting.
