Row Spacing Data Legend
Refer to Figure 125
Find the chart for your drill width (15ft, 20ft or 25ft) and
row spacing. A 25-foot example is shown above.
, : The heading and title block identify the drill
model, size, row unit type, default row count, default row
spacing, and whether the diagram applies to a standard
or modified row spacing.
: Span is the dimension between the centerlines of the
left and right outside row units. If all are active, only a sin-
gle “Span” value is given. If some are inactive, a “Base-
line Span” for all rows is given, as well as an “Active
Span” for just the rows in use. You may need this data for
modified row spacings not shown.
: Swath is the average width of successive planted
passes. Swath times distance traveled is area planted.
Swath is always wider than the [Active] Span.
: Row Spacing
Shows standard or “Active” row spacing.
For “TRS” models, with all row units in use, a
“Swath-Averaged Row Spacing” is given, as the Pair and
Split row spacings are dissimilar. The gap between
passes is somewhat arbitrary. The data in this manual
was developed to make all TRS swaths a consistent 10in
average row spacing across the planted area.
: Each illustration shows three drills, their tool bars
represented by the horizontal lines.
: The large top arrow shows drill centerline the direc-
tion of travel. This is always drill centerline, and not nec-
essarily the center of the presently active row units.
: Solid lines with arrows across the tool bar show
active row units.
: Dashed lines without arrows across the tool bar
show inactive row units.
, :Marker Extension values are shown separately
for left and right side opposing passes. They may not be
the same, and can be substantially unequal, particularly
for modified spacings.
For setting marker extension, measure from the mark to
the centerline of the outside row unit on each side,
whether that row is active or not. Measure to the outside
row unit of a twin pair.
Note: Opposing passes are presumed for these exten-
sion values. For concentric passes, only one
marker side is used. Measure from drill centerline
to the mark, and set the extension to the Swath
value
for your configuration.
