Leveling Controller

The electronic leveling controller (A) is located
behind the inspection door on the operator's
platform above the leveling manifold. The
controller processes slope information and
outputs signals to the hydraulic leveling valve.
When auto leveling is activated the leveling
controller levels the chassis up to a maximum
slope of 27%.

Header Tilt Manifold

Located on the left side of the feeder house is the
header tilt manifold. This manifold diverts flow
to the cylinder in the feeder house pivoting the
header. The hydraulic valve fully integrates with
the combine's electronics to provide auto lateral
tilt. If the combine was originally equipped with
Contour Master then the stock valve is used to
control the header tilt.
Overcarriage Position Indicator
Attached to the overcarriage and undercarriage
is the position indicator (C).
indicator outputs a signal to the controller
of
the overcarriage position relative to the
undercarriage. This also acts as a maximum
level indicator. When the combine is nearing
maximum level the controller reduces the amps
to the leveling valve decreasing the hydraulic
flow. This provides for smooth leveling when
achieving maximum level.
Header Position Sensor
Located on the right side of the transition is
the header position indicator (D). It utilizes a
linkage between the face plate and the transition
to indicate the header position relative to the
combine. The position is then displayed in the
corner post of the cab.
