Setting Material Rates
Planting Rate
Adjusting the planting rate requires the following:
1. Monitor configuration:
The seed monitor must be set up with the correct
row count, row spacing and disc cell count. See the
Seed Rate Manual (SRM) and the DICKEY-john
®
Planter/Drill Control (PDC).
2. Preparing rows:
Correct seed disc selection and Y-tube settings are
required for correct rate. Meter shutter setting and
meter pressurization adjustments assure the rate.
See the SRM.
3. Ground speed calibration:
Seed monitor rate control and reporting is only as
accurate as the speed reported by the radar. See the
PDC manual.
4. Setting seed rate via seed monitor:
See the SRM and the PDC manuals.
5. Checking planting rate:
Although the seed monitor reports a computed
population based on seeds sensed, only an actual
furrow check provides certainty about the actual
seeding rate. See the SRM.
