Implement Lift Switch Adjustment
Refer to Figure 96 and Figure 97
An implement lift switch
on the drill turns seed meter-
ing off when the implement is raised, by commanding
a
a
linear motor to retract the ground drive arm. To adjust the
switch activation height, first locate the lift switch on the
implement (center section, right rear parallel arms).
If changes have been made to tool bar height (page 26),
or if the switch was removed for any reason, it needs to
be adjusted for activation height.
Pinch / Crush Hazards:
Shut off tractor and remove key while adjusting switch. Do not
place any part of body under implement or near moving parts
while checking adjustments.
Wings must be unfolded to prevent lift lock from engag-
ing. Lower the openers until at a height where seeding
should start (usually just above ground). Turn off the trac-
tor and remove the key. Securely support center section
tool bar at this height with jack stands or blocks.
Loosen switch pivot screws . Adjust switch angle so
that toggle is level, or slightly tilted up to the right.
Loosen bracket bolts and slide switch up or down
until the flexible switch toggle is just past the point at
which the switch is activated (flexible switch toggle
deflected up).
Note: The implement lift switch has three wires (black,
red and green). In order for the switch to work prop-
erly, the correct two leads must be connected to the
lift switch extension cable.
The extension cable black lead always connects to
the switch black wire. The extension cable red lead
must connect to the switch green wire.
a. The contact drive also disengages on Master SW Time-out (master switch ON, but ground speed 0 for a period of time greater than
specified in the configuration menus). If the variable Rate Kit option is installed, and the seed monitor is in either of
GRAN SEED CONTROL or GRAN FERT CONTROL, the Master Switch must also be ON for ground drive to engage.
