Seed Rate
Seed rate on this family of drills is controlled by:
•
selection of seed meter, and seed wheel or finger
count, and
•
the rate set on the hydraulic drive console.
About Hydraulic Drive Rate
Before it can control seed rate, the hydraulic drive
console must be:
•
configured with information about your drill and
intended planting speed,
•
configured with a calibration number for the seed,
meter and rate range, and;
•
calibrated to fine-tune the seed rate calibration
number and ground speed radar. Calibration is
essential for volumetric seeds, because the seed
metered by each meter wheel revolution varies with
the seed.
Calibration is described starting on page 42.
With those steps completed, field seeding rate is
controlled manually by adjusting the target
“set=
” rate
using the /
arrow buttons. Rate can also be controlled
by a pre-loaded “recipe” or an external GPS controller.
In field operation, the hydraulic drive console displays:
set=
the currently active desired seeding rate
out=
the current system seeding rate
spd=
(over number), the current speed
Seeding Depth
Seeding depth
is controlled by one or more of:
•
frame-mounted coulter depth
(if present),
•
unit-mounted coulter depth (if present),
•
side depth gauge wheel (Series dependent), and;
•
and press-wheel height
(Series dependent).
Adjust frame height first (page 72), then make row unit
adjustments. Each opener Series is covered separately:
10 Series
10HD Series
20 Series
25 Series
