Singulated Planting Overview
The information in this section covers important setup
and checking information that applies to both:
Singulator Plus (wheel, at left in Figure 2) meters and
Finger Pickup meters (at right in Figure 2).
There are additional Sections for each meter. See also:
“Finger Meter Planting” on page 14 and
“Singulator Plus™ Meter Planting” on page 7.
Singulating planting employs the seed monitor in
“PLANTER CONTROL” mode. Volumetric planting uses
“GRAN SEED CONTROL” or “granular” mode, and is
covered at “Volumetric Meter Planting” on page 24.
Population Risk:
If the seed monitor is presently in GRAN SEED mode, follow
the setup instructions carefully. Switching between seeding
modes can cause some planter configuration values to be reset
to defaults that are incorrect for your planter.
Population Reference Information
Seeds per Unit
If only pounds/acre (kilograms/hectare) is known, obtain
the population count by multiplying the population weight
by the “Kernels per pound” value from the seed
container.
Seed Spacing
If only seed spacing is known, use the tables on
pages 5, 6 and 54 to determine population.
1. For your crop, determine your intended population, in
seeds/acre or seeds/hectare. If you know only the
population, the charts on page 5 and 54 correlate
population to seed spacing for several row spacings.
2. For your crop, population and desired field speed,
verify the suitability and setup of your meter type,
and seed wheel part number or finger count.
For Singulator Plus seed meters and wheels, details
and charts are found in “Singulator Plus™ Meter
Planting” on page 7.
For Finger Pickup meters, details and charts are
found in “Finger Meter Planting” on page 14.
