Material Rates Overview
Details of seed and fertilizer rate setting are found in the
Adjustments
section, and rely on data from the Seed
Rate Manual.
Rate setting controls are different for each box, but inde
-
pendent for each box. Some boxes have more than one
control.
Basic rate settings are found in the Seed Rate Manual
(part number , normally located in the Manual
-
Pak™
enclosure at front center of drill).
All chart rates, for all boxes, are approximate. strongly
recommends calibration of each box to the material to be
applied.
Seeding Depth Overview
Setting nominal planting depth, and achieving it
consistently, is affected by multiple adjustable drill
functions, which can interact. From greatest to least
effect they are:

Coulter Height
(page 17)
The coulters prepare soil ahead of the openers, and
are typically set slightly deeper than the openers.
The openers thus only need to open the tilled shaft
into a V
-
shaped furrow. The openers cannot gener
-
ally run deeper than the coulters, and running them
too close to coulter depth may result in uneven seed
depth.
Opener Depth
(Press Wheel Height) (page 37)
Using the T
-
handle, in no
-
till conditions, opener
depth can be set near, and at any level above
coulter depth.
In soft or conventionally tilled soil, the opener disc
depth is more independent of the coulters.
Row Unit Down Pressure
(Spring) (page 35)
In most conditions, the factory spring setting is suffi
-
cient to make a consistent furrow in the coulter
-
pre
-
pared soil. In extremely heavy conditions, with the
coulters running at the desired depth, the openers
may be making a furrow of inconsistent depth.
Rather than increase the coulter depth, you can
increase opener down force at the row unit springs.
Never back up with openers in the ground. To do so may cause
damage or opener plugging.
