Introduction
This manual covers the following tasks for 60-foot
three-section Yield-Pro®Planters equipped with Air-Pro
seed meters:
• setting and checking seed rate for singulated crops
• applying liquid fertilizer from optional tanks on-board
the planter, or from a trailing cart.
This manual is your guide to planter adjustments for
achieving specific seed population targets. It also
includes information you may need to properly setup and
adjust a separately provisioned fertilizer tank and pump
system.
Although some setup/adjustment material herein is
repeated from the Operator’s Manual, you need to be
thoroughly familiar with planter operations and
adjustments before applying this Seed Rate manual and
its table data.

Rate Setting Overview
Setting Planting Rate
There are five or six steps to obtaining the desired
number of seeds per acre, depending on row
configuration. This data applies to the Air-Pro
when planting at one
1. For your crop, determine your intended population, in
seeds/acre or seeds/hectare. If you know only the
seed spacing or pounds/acre (kg/hectare), consult
the charts on page 2 through page 4.
2. For your crop, population and desired field speed,
verify the suitability and setup of your seed disk:
See “Air-Pro® Meter Disk Selection” on page 5.
3. Set initial seed inlet shutter per seed rate chart.
Set initial meter pressurization per page 8, 9.
4. Sprocket index for staggered twin-row
Twin-row planters, with certain crops, get maximum
benefit with precise seed spacing between adjacent
rows. See “Indexing Fine Adjustment” on page 25.
5. Set meter rate
This is done via the seed monitor. Once data about
your planter is entered, you select the seed rate
directly. Consult the manual for the seed monitor.
6. Check planting rate
See “Checking Planting Rate” on page 10.

meter
Setting Fertilizer Rate
If your planter is equipped with one or both optional
fertilizer manifold systems, it does not include the tank.
If the planter has a Type 2b (formerly referred to as a
“starter”) manifold, it may rely on an off-planter pump, or
may use one or two ground drive pumps on the planter.
See “Ground Drive Fertilizer Rate” on page 42 for
ground drive pump configuration.
If the planter has a Type 3
“hi rate”) manifold, it relies on an off-planter pump,
typically the pump on a Great Plains PFC1600 or
PFC2000 tank cart.
Rate setting for the cart pump is found in the cart’s
Operator manual.
Rate is controlled by the pump. Consistent distribution
requires using the correct size orifices in the manifolds. If
the orifice size is too large, flow may not be even across
all rows. If the orifice size is too small, material may be
dumped at the relief valve.
See “Fertilizer Rate” on page 39 for orifice information.

Operator manual, under Setup topic “Fertilizer
Connections”.

Population Reference Information
Seeds Per Unit
If only pounds/acre (kilograms/hectare) is known, obtain
the population count by multiplying the weight by the
“Kernels per pound” value from the seed container.
Example: Milo
Target rate: 4.5 pounds/acre
Seed density: 14500 seeds/pound
Population: = Rate × Density
= 4.5 × 14500, or:
65250 seeds/acre
Seed Spacing
If only seed spacing is known, use the tables on the next
five pages to determine population.

Meter Pressurization
Refer to the Operator Manual for the procedure for fine
tuning meter pressurization.
Start with pressures from below and on page 9, which
are based on crop, and for corn, seed shape and density.
Note: These are suggested initial (starting) pressures.
Use the seed monitor console to adjust them up or
down per the procedure in the YP2425A Operator
Manual.
Corn: Reading a Pressure Chart (below, next page)
1. Pick the chart based on seed shape (flat, round).
Example: large round corn
2. Pick a line based on seed size (large, small).
Example: the right line below
3. Find the seed density on the bottom scale.
Example: 1260 seeds/pound
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 and foreign material can affect the
planting rate.
Any material difference between chart and field rates
implies a mechanical malfunction, a planter setup error
or extremely worn planter components. You can verify
your setup and planter performance by measuring seed
placement and spacing over a relatively short distance.
The columns to the right provide example data for a rate
check, in U.S. customary units and a similar example
metric units.
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. For populations above 100 000 seeds/acre, use a
sample size of 1/1000th acre.
For populations below 100 000 seeds/acre, use a
sample size of 1/200th acre.
4. Configure the planter for the chart rate, either using
the chart settings for sprockets, or, with hydraulic
drive, selecting the rate on the seed monitor.

5. Plant at the desired planting speed for slightly more
than the computed sample run length.
6. Measure off the sample distance, balanced in
between where seeding started and stopped.
7. Count the number of seeds over the distance
measured. Also note the consistency of the seed
spacing.
8. Compute the rate for a full acre or hectare.
For a 1/1000th sample, multiply the counted seeds
by 1000.
For a 1/200th sample, multiply the counted seeds by
200.
9. 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, hydraulic drive setup, chain
slack, etc. If seed spacing is irregular, this suggests
a seed delivery problem, and not a rate setup
problem.
10. 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.

Sample size:
1/1000th ac
Plant for approximately:
25 feet
Measure the central:

USc Example:

Planting Rate
Singulated planting employs the seed monitor in
“PLANTER CONTROL” mode.
Hydraulic Drive Meter Rate
Hydraulic drive meter rate is set directly on the seed
monitor in the tractor. Consult the monitor manual for
detailed instructions, which may vary slightly over time
with firmware updates to the monitor system.
Enter/update your planter configuration (width/row-count,
single-row/twin, disk cell count, etc.). Once entered,
specify the population directly in seeds/acre or seeds/ha.
Enter meter RPM limits for your disk (pages 13-20).
Note: For consistent results, and least meter wear, do not
exceed the recommended ground speed.
For step 1 through step 4, any needed data not provided
in this manual can be found in one or more of:
DICKEY-john
®
Quick Start Guide
Planter Operator Manual
Refer to the DICKEY-john®IntelliAg® Planter/Drill
Control Operator’s Manual for details on setup item.
Note: The monitor must be in User Level 2 to change
some of these parameters.
1. For a crop not previously planted with this planter,
create a “Material Name” for the crop. Selecting a
named material is a required step in later screens.
2. Verify, and as needed setup or update the “Material”
record for the singulated seed to be planted.
The table at right lists the parameters that need to be
reviewed or set. <angle bracket> values are your
choice/preference when not from meter rpm chart.
3. Verify, and as necessary setup or update the
“Channel” assigned to the planter’s hydraulic drive.
If the monitor resets to defaults, Gear Ratio may be
incorrect.
Count rows individually for “# Seed Rows”. A twin
pair (if both openers are in use) counts as 2 rows.
“Channel Width” is swath.
4. In the Material Library screen, makes sure that the
Material (SOYBEANS in our example) is assigned to
the Channel (CH 1 in our example) which controls
the planter’s hydraulic drive.
5. Perform a Valve Calibration for the control channel.
6. Switch the seed monitor from Setup/Configuration
mode to Operate mode. Load seed. Move the planter
to the field.
