PL5800 Planter Table of Contents Index Operation
To adjust the seed inlet gate, squeeze the tabs (1)
and move the gate up or down as necessary. There
are four settings for the gate (“I”, “II”, “III”, and “IIII”).
Setting “O” opens the gate for clean-out. Setting “X”
closes the gate and is commonly used for row shut-
off and meter re-fills.
The table is a general summary of gate settings.
Seed Pool Slopes
The best seed pool slope results in the most
consistent seeding with minimal skips and doubles.
The illustrations below are found to be the best seed
pool slopes for sample seeds.
If the suggested initial gate setting does not work for
your seed, adjust the seed inlet gate.
For medium size and smaller seeds that flow easily,
the slope runs from just above the 8:00 position on
the housing wall, forward and down to one or two
seeds deep at the base of the rear strip brush (1).
For medium size and larger, or heavily treated
smalled seeds that flow less easily, the slope runs at
or slightly above the 8:30 position on the housing
wall, forward and down to three to six seeds deep at
the base of the rear strip brush (1).
Keep the top left/rear end of the pool below the 9:00
position (meter horizontal center-line).
In general, the seeds at the base of the strip brush
need to be deep enough that no air escapes there,
and so that just enough seeds are present to begin
populating the cells.
Seed Meter Re-fill
Once planting is underway with the seed pools set, it
is occasionally possible for bridging at or above the
seed inlet to starve the meter of seed.
An empty meter causes a seed monitor “Row
Failure” alarm with a report of the row number.
Row numbers are counted from the left. The
outside row is row 1.
1. Stop and put the tractor in park. Leave the fan
running.
2. Locate the failed row, remove the rain cover, and
verify that the meter is empty. Note the gate
setting.
3. Temporarily open the gate one or two notches
wider.
a. If the problem was inlet bridging, seed should
flow into the meter immediately.
b. If inlet bridging is not the problem, little or no
seed flows into the meter with the gate open
wider. In this case, the problem is further up in
the seed flow.
Close the gate completely for about 15 seconds.
This prevents meter pressurization air from
