Refer to Figure 13
At the parameter 4 screen (Row Width), enter the row
spacing of the drill (in inches or cm, to 0.1 precision).
Use the base row spacing, even if re-configuring for twin
row or split row operation.
Use the exact row spacing from the charts beginning on
page 176. If the chart shows a “swath-averaged”
spacing, use that figure. It accounts for irregular spacing
on TRS models and extra inches at wing joints. For
example, on a 64-row 7.5 inch (nominal spacing) drill,
the swath-average spacing is 7.56 in, or 7.6 in.
The monitor console uses Row Width, plus the
auto-detected row count, to calculate an Implement
Width. IMP WIDTH can vary slightly from the actual, due
to round-off. For a 64-row 7.6 in drill, it computes 0486.4,
which is about half a percent too wide.
Refer to Figure 15
If, at the parameter 5 screen, the computed Implement
Width is not precise, you can override it to the value from
the charts beginning on page 176.
In the example at right, the computed “0486.4” has been
revised to the exact chart swath width of 484 inches.
If you operate with rows shut down for twin- or skip-row,
revise the Implement Width to the chart value for that drill
configuration. You do not need to alter the Row Spacing
parameter (the console accounts for the active row
configuration in the Split Row setup screen).
Refer to Figure 15
The parameter 9 screen configures which rows are
operating. The factory default is Pattern 00 (all rows).
This is correct for single-row (all rows), factory twin-row
and all-row TRS operations.
If you operate with rows shut down for twin- or skip-row,
change the Pattern number based on a comparison of
the pattern table in the DICKEY-john manual, and the
active rows from the charts beginning on page 176.
Also revise the Implement Width to the chart value for
that drill configuration. You do not need to alter the Row
Spacing parameter (the console accounts for the row
configuration in the Split setup screen).
