PL5800 Planter Table of Contents Index Operation
To increase meter pressurization:
1. Adjust hydraulic flow to meter pressure change.
2. Wait 5 to 10 seconds for the system to update
while you continue planting.
3. Continue making small decrease adjustments
until the reported population levels out at the
target value.
Doubles
If everything else is correct, and the overall average
population is running high, or there are double seeds
when doing a furrow check, the cause may be two
seeds in some disk pockets at delivery to the seed
tube. Decrease meter pressurization to correct this.
To decrease meter pressurizations:
1. Adjust tractor hydraulic flow.
2. Wait 5 to 10 seconds for the system to update
while you continue planting.
3. Continue making small decrease adjustments
until the reported population levels out at the
target value.
Fine Tuning Meter Pressurization
After several passes, if you are comfortable with the
planter operation, optimize the meter pressurization.
Do this during longer passes, so there are fewer
distractions.
1. Observe the current overall average population
reported by the monitor.
2. Adjust the meter pressurization down in small
increments, waiting 5 to 10 seconds between
adjustments, until skips occur. Not the pressure
where skips begin.
3. Restore the pressure to the initial value at step 1.
4. Adjust the meter pressurization up by small
increments until doubles occur. Note the
pressure at the which doubles begins.
If unable to adjust up to doubles, or if skips
happen instead, seed delivery is probably being
starved of iar.
Increase fan rpm and repeat limit search.
5. Adjust meter pressurization to a value halfway
between the limits established at step 2 and step
4. This is the ideal value for your crop, disk, and
population, providing equal margin against skips
and doubles. Record this value for future use.
Alternate Skips/Double Check
Small seeds (particularly milo), and high populations
(particularly soybeans), may not be sensed as skips
or doubles by the seed tube sensors, and watching
monitor population is unlikely to locate the pressure
limits. The following test can also be quicker for all
seeds:
1. After planting a few passes with initial settings,
remove the rain covers from several seed
meters. Use rows with a variety of seed hose
lengths and routes.
2. Make a meter pressurization adjustment, and
resume planting for pass or less.
3. Stop the planter motion but leave the fan running.
4. Inspect the seed disks closely. Look for empty
seed cells, skips, and cells with multiple seeds
(doubles).
5. Repeat steps 2 through 4 until limits are
established. Record the limits and calculate an
average.
6. Install the rain covers and plant with the
calculated average.

Planting Rate
Always check seed delivery rate before planting.
The seed monitor can count most singulated seeds,
but may not reliably the smallest seeds, such as
milo. It does not count individual volumetric seeds,
and several factors can cause large seed singulated
reports to be inaccurate (such as incorrect speed
calibration, Sensor Constant, or Gear Ratio setup).
Methods of rate checking are described in detail in
the Seed Rate manual. This is an overview of the
general process, which varies with the seed type and
planter meter drive type.
