Abstract:
A combine harvester cleaning element and remote adjustment mechanism comprising:a plurality of adjustable louvers carried by a frame; an adjusting bar arranged normal to the louvers and being movable in a lengthwise direction of the adjusting bar; a powered actuator having a linearly movable output member fixed to the adjusting bar for moving the adjusting bar and holding the adjusting bar in a selected position whereby the louvers are set in a selected position between a fully opened position and a fully closed position; a control system for the actuator including a first sensor that generates an output signal when the output member is in a home position that corresponds to a known position of the louvers and a second sensor that generates a signal corresponding to the movement of the output member whereby the opening of the louvers can be determined by the extent of movement of the output member from the home position.
