Adjusting ContourMax
™
Wheels with Foot Switch
The ContourMax
™
wheels allow the header to mirror the contours of the ground, and can be adjusted between 25 mm
(1 in.) and 457 mm (18 in.) from the ground surface. A foot switch allows the wheel
’
s electronically actuated hydraulic
functions to be controlled from the combine cab.
DANGER
To avoid bodily injury or death from the unexpected startup or fall of the raised header, stop the engine, remove the
key from the ignition, and engage the safety props before going under the header for any reason. If using a lifting
vehicle, be sure the header is secure before proceeding.
