Frame Level
Other than “Eyebolt Adjustment” on page 20, there is
no specific setup adjustment for leveling the wings to the
center section. When beginning planting, check frame
level with row units in level ground.
If one or both wings are angled up or down, check and
adjust the following items:
• opener sub-frame adjustment: all gauge wheel trun-
nions in same frame pivot holes - see “Opener-Sub-
frame Adjustment” on page 39
• weight transfer setting - see “Adjusting Weight
• opener pivot height: all openers pivoting in same hole
at their mounts (possibly excepting rows in tire tracks)
- see page 41
• opener press wheel height: all row units set the same -
• opener spring down-force: all row units set the same
(possibly excepting rows in tire tracks) - see page 41
Implement Lift Switch Adjustment
Refer to Figure 39
(which, for clarity, depicts the switch region without openers
or gauge wheel)
An implement lift switch on the implement turns seed
metering off when the implement is raised. To adjust the
height at which seed metering is turned off, follow these
steps:
1.
Do not place any part of body under implement while
making adjustments.
2.
Locate the implement lift switch
on the front center
of the mainframe.
3.
Raise openers completely and lock them up by set-
ting Transport/Field valve handle to TRANS.
4.
Loosen switch mount bolts
and slide switch up or
down until actuator
makes contact with the lift arm
and switch is reliably toggled on (up).
5.
Tighten bolts.
Note: Do not set the switch to come on too low. The lift
arm can ride up and down over irregular ground,
and an early switch could result in patches of no
seeding.
If eyebolt adjustment is changed (see page 20), re-check
implement lift switch.
Note: For reference, the ADC2350 lift switch wiring is:
Black (switch COM) to black (extension)
Red (switch N.C.) to red
Green (switch N.O.) not connected
Circuit open when drill is raised
