Planting Rate Overview
The information in this section covers important setup
and checking information that applies to the Air-Pro
®
meter in singulated planting.
Singulated Rate Setting Summary
1. For your crop, determine your intended population, in
seeds/hectare. If you know only the seed spacing or
population in kg/ha, consult the conversion formula
below.
2. For your crop, population and desired field speed,
select the correct seed disk:
“Air-Pro® Meter Disk Selection” on page 4
3. Set meter rate (page 11).
4. For staggered twin row, time row pairs using:
“Sprocket Indexing (Stagger)” on page 24
5. Set initial seed inlet shutter per seed rate chart.
6. Set initial meter pressurization per page 6, 7.
7. Verify your planting rate per the instructions at:
“Checking Planting Rate” on page 8. If the results
are consistent with your setup, plant the crop.
Population Reference Information
Seeds per Unit
If only population weight (kilograms/hectare) is known,
obtain the population count by multiplying the population
weight by the “Kernels per kg” value from the seed
container.

Meter Pressurization
Refer to the Operator Manual for the procedure for fine
tuning meter pressurization.
Start with pressures from below and on page 7, which
are based on crop, and for corn, seed shape and density.
Note: These are suggested initial (starting) pressures.
Adjust them up or down per the procedure in the
Operator Manual.
Corn: Reading a Pressure Chart (below, next page)
1. Pick the chart based on seed shape (flat, round).
Example: round corn
2. Pick a line based on seed size (large, small).
Example: large round corn, the right line below
3. Find the seed density on the bottom scale.
Example: 2800 seeds/kg
4. Read the suggested starting pressure on the left
scale, where the line (example shown as dotted
gray) intersects the density.

Checking Planting Rate
Singulated seed charts are based on cleaned and sized
seed singulated with the recommended disk. Extreme
seed size variations, foreign material and tire pressure
can affect the planting rate.
Any material difference between chart and field rates
implies a mechanical malfunction, a planter setup error,
unsuitable planting conditions (such as excessive tire
slippage) or extremely worn planter components. You
can verify your setup and planter performance by
measuring seed placement and spacing over a relatively
short distance.

Checking Singulated Rates
1. Determine the sample distance to check. Find your
row spacing in the table at right.
2. Note the number of rows to sample. Adjust the
planting depth to a shallow setting on one or two
outside rows (per table). Tie up the press wheel
arms with wire or bungee to prevent furrow closure.
3. Configure the planter for the chart rate, using the
chart settings for sprockets.

4. Plant at the desired planting speed for slightly more
than the computed sample run length.
5. Measure off the sample distance, balanced in
between where seeding started and stopped.
6. Count the number of seeds over the distance
measured. Also note the consistency of the seed
spacing.
7. Compute the rate for a full hectare.
For a 1/1000th sample, multiply the counted seeds
by 1000.
8. If the field and chart rates vary by more than a few
percent, re-check planter setup, including meter disk
or cell count, air system, tire size, tire pressures,
sprocket setup, chain slack, etc. If seed spacing is
irregular, this suggests a seed delivery problem, and
not a rate setup problem.
9. While planting, pay attention to the seed monitor. In
addition to confirming the single-row furrow check, it
will also provide field rate data on all the other rows,
and alert you to any irregularities or stoppages.

a If the sample size is less than 100 seeds, you may want
to double or triple the number of rows sampled, so as to
increase the precision of the count.

Planting Rate
Setting the seeding rate requires the following steps:
1. monitor setup
2. seed disk selection,
3. drive speed Range sprockets,
4. Transmission sprockets,
5. inlet shutters
6. meter pressurization,
7. checking seeding rate.
All rate adjustments are performed at the left end of the
planter. There are no adjustments at the ground drive
assembly. Changes in seed rate do not affect fertilizer
rate.
1. Rate: Monitor configuration:
The seed monitor must be set up with the
• correct row count,
• correct row spacing,
• speed calibration and;
• expected population limits, in order to have accurate
rate reports and useful alarms.
See the DICKEY-john® Planter Monitor operator (PM)
manual.
If you only plant with the factory configuration of the
planter, you never need to update row count and
spacing. If any rows are unused, adjust the monitor
setup.
Speed calibration must be done prior to first use, and
re-calibration is recommended periodically, particularly if
soil conditions change.
Null4:
Figure 4
Monitor Setup Screen
31809
2. Rate: Disk Selection:
Select seed disks per page 4 and page 5. See Operator
manual for installation. Disks are specific to crops. Some
crops have multiple disks available, to cover both seed
varieties, and different populations within disk rpm limits.
Disks have a high and low rpm limit, which also
corresponds to a high and low field speed limit. The
charts account for these limits.
See “Air-Pro® Meter Disk Installation” in the Operator
manual.
If any rows are unused, install special blank disks. See
“Row Unit Shut-Off” in Operator manual.

3. Rate: Range Sprockets
Range sprockets provide coarse control of seed rate.
Refer to Figure 6 and Figure 7
All Seed Rate charts specify a DRIVING and DRIVEN
sprocket combination for the Range. Crops with more
than one range are noted as “LOW RANGE” or
“HIGH RANGE” at the top of the chart.
To change Range:
a. Rotate the idler plate against the spring to

disengage the idler.
Remove the chain.
b. Remove pins from shaft ends at DRIVING and
DRIVEN sprockets, as well as at storage shaft.
c. Exchange sprockets so that new DRIVING and
