Drill Bit Method
A - Screw
B - Notch
C - Shank of 2.5 mm (3/32 in.) Drill Bit
D - Adjustment Tool
Loosen double eliminator screw (A). Double eliminator must
move freely.
-
Ensure double eliminator is set for ProMax 40 disk. (See INSTALL
DOUBLE ELIMINATOR in this section.)
-
Install a ProMax 40 disk in meter.
-
Turn handle clockwise to latch disk in place.
-
Rotate disk until screw (A) is centered in notch (B) of disk.
-
NOTE: Contact your John Deere™ dealer for adjustment tool
JDG10965.
Insert adjustment tool (D) or shank of a 2.5 mm (3/32 in.) drill
bit (C) into disk hole.
-
Position double eliminator against tool or drill bit, so highest
ridge on double eliminator is in light contact with tool or drill
bit.
-
Press firmly on disk, double eliminator, and cam nut. Tighten
screw so double eliminator cannot move.
-
Remove tool or drill bit. Double eliminator is now set for 50
percent hole coverage.
-
A setting with 50 percent hole coverage is optimal for most
sizes of field corn. For extremely small or large seeds, loosen screw
(A) and turn cam nut to increase or decrease hole coverage. The objective
is to adjust the double eliminator to dislodge one of two seeds covering
a single hole while allowing single seeds covering a single hole to
pass by undisturbed. When double eliminator is in position, tighten
screw.

A - Disk
B - Inspection Area
Seed disk must turn smoothly with light contact. A small
gap between seed disk and housing is acceptable. Seed must not pass
between disk and meter. To improve inspection process, place a small
amount of seed in meter.
Turn seed disk (A) by hand and inspect gap between disk and
meter in area (B). If disk turns too hard or if seed passes through
gap, adjust hub position. (See ADJUST METER HUB in this section.)
-
Close meter and attach to hopper using wing nuts previously
removed.
-
Set all rows the same.
-
Plant a short distance, then perform a field check to determine
seed delivery and meter performance. Adjust individual meters as necessary.
