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 disk cell count. See the
Seed Rate Manual (SRM) and the DICKEY-john
®
Planter/Drill Control (PDC).
2. Preparing rows:
Correct seed disk 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.
Height Switch Adjustment
The implement name includes a sensing switch
that
signals the seed monitor (and activates the optional
hydraulic meter drive), when the product is lowered for
planting. The switch is located at the rear cross tube on
the implement name’s left side.
Although factory-preset for typical planting conditions,
Great Plains recommends adjusting this switch for your
exact field conditions and planting depth.
Crushing Hazard:
Exercise extreme caution when adjusting the switch.
1. Lower the product to the height at which seed
delivery is to begin.
2. Loosen bolt
holding switch bracket
to plate
.
3. Move bracket forward or rearward so that switch
toggle arm makes contact with rear cross tube
.
4. Tighten nuts.
Switch is in “Neutral” position when planting. Switch is
“Activated” when raised.
