Implement Lift Switch Adjustment
Refer to Figure 79, which depicts a model NTA3510 drill.
An implement lift switch on the drill turns seed metering
off when the implement is raised. To adjust the height at
which seed metering is turned off, first locate the lift
switch on the implement. See table below.
Do not place any part of body under implement while making
adjustments.
CTA4000 and CTA4000HD Lift Switch
Raise openers completely. Lock them up by moving the
FIELD/TRANS valve handle to TRANS. Loosen switch
mount bolts and slide switch up or down until the flexible
switch toggle makes contact with the top of the opener
sub-frame arm (toggle is bent up). Adjust the switch until
the toggle activates the switching.
NTA3010 and NTA3510 Lift Switch
Lower the implement until at a height where seeding
should start (usually just above ground). Turn off the
tractor and remove the key. Securely support implement
frame at this height with jack stands or blocks. Loosen
switch 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 not contacting
anything).
3N-4010HDA Lift Switch
Lower the implement until at a height where seeding
seeding should stop (usually just above ground). Turn off
the tractor and remove the key. Securely support
implement frame at this height with jack stands or blocks.
Loosen switch bracket bolts and slide switch up or down
until the flexible switch toggle makes contact with the
bottom of the implement rear parallel lift arm. Adjust the
switch until the toggle activates the switching.

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 wire color indicated in the table below, for
your implement.
