Row Implement Adjustments
Frame-Mounted Coulters (Option)
Coulters are factory-installed if ordered with the
implement, and are configured for in-row operation at
knife or tine shoe depth. They can be set for fixed or
limited castering.
Coulter depth is adjusted via the shaft
, at the tool bar
clamp. Loosen the U-bolt nuts
. Slide the shaft up or
down. Check coulter-to-knife/tine alignment. Re-tighten
nuts.
For in-row, adjust the coulter depth for a running depth
at the bottom of the knife or tine shoe, or about
3
/
4
in (19mm) below application level.
For fields where frequent sharp turns are unavoidable,
you can reduce coulter plowing by allowing the coulter to
caster at the pivot casting. Loosen the jam nuts at
.
Loosen the set screws just enough to allow the casting to
swivel. Re-tighten the jam nuts. Do not remove the
center stop screw.
Refer to the Vantage I manual (204-376M) for further
coulter adjustments.
Coulter arms normally operate resting on their down
stops. They ride up and compress the springs briefly as
obstructions are encountered.
Do not adjust the spring
tension
. If you service a coulter, reset the spring
tension to the factory length of:

Sensor Adjustment
The proximity sensor on the left-hand side of the front
of the machine is for starting the gull winging process.
This sensor should be set to activate by the upper lift
arm. Once the arm passes the sensor, the gull winging
process will begin. The rear proximity sensors are
located near the wing hinges. They control the height or
angle of the gull winging process.
All three sensors should be given between 1/8-1/4”
clearance.
To adjust, loosen the hardware securing the sensor,
then slide the sensor up or down in the bracket. The
further the sensor is raised in the bracket the more
delayed the gull winging process will be. Once the
sensor is set to the desired position, secure the sensor
with hardware. Test this configuration by lifting and gull
winging the wings of the machine. If you want gull
winging to delay or hasten the process more, make
further adjustments until satisfied.
