Optimal crop flow begins with the front attachment. CLAAS front attachments are equipped with the CONTOUR and AUTO CONTOUR automatic front attachment guidance systems in order to ensure that the cutterbar always follows the ground contours precisely.
You can set the required cutting height conveniently via CEBIS.
Cutterbars with CONTOUR adjust automatically to ground irregularities along the direction of travel. AUTO CONTOUR goes one step further, additionally enabling automatic compensation for surface irregularities across the direction of travel.

Sensor bands under the cutterbar are deflected by the undulations and trigger the actuation of the corresponding cutterbar rams.
