Implement Lift Switch Adjustment
Refer to Figure 97 and Figure 98
An implement lift switch
on the drill turns seed
metering off when the implement is raised. To adjust the
switch activation height, first locate the lift switch on the
implement (centre section, right parallel arms).
Do not place any part of body under implement while making
adjustments.
Wings must be tilted down, and may be folded forward to
ease access to the switch. Lower the openers until at a
height where seeding should start (usually just above
ground). Turn off the tractor and remove the key.
Securely support centre section sub-frame 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 rear.
Loosen bracket bolts and slide switch up or down
until the flexible switch toggle is just past the point at
which the switch is actuated (flexible switch toggle
deflected down).
Note: The implement lift switch has three wires (black,
red and green). In order for the switch to work
properly, 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 red wire.
