See how it works: (This was taken at the Husker Harvest show at the cross flow cleaning demonstration unit)
Cross Flow cleaning system on 140 series Case IH combines:
This system will provide the necessary compensation when combining on side-hills. The Cross Flow system will help to prevent the one-sided sieve overload by providing side
strokes on the upper sieve moving the crop onward to the clean grain auger and then to the tank. The Cross Flow system detects the side-hill angle by a sensor located in the cab. The steeperthe side-hill, the more the upper sieve strokes towards the uphill side. The Cross Flow system is controlled by an electric actuator and the system will compensate for side-hill slope.
