Marker Extension
The diagrams in this section show marker extension dis-
tances for all supported row unit configurations of all
drills covered by this manual. Measure from the centerline of the outside row unit
present (not the outside row unit in use) on each side.
Reading a Marker Extension Diagram
Refer to Figure 72
Find the chart for your drill width (20ft or 25ft), row unit
Series (20 or 25), and row spacing.
The Figure title block identifies the drill model, size,
row unit type, default row count, default row spacing, and
whether the diagram applies to a modified row spacing.
Each illustration shows three drills, their tool bars repre-
sented by the horizontal lines
. The large arrows
show the direction of travel.
The small arrows show active row units. For modified
row spacings, the short vertical lines (no arrows) show
which row units to shut off.
Note that Left and Right extension dimensions may
not be the same, and can be substantially unequal.
