Abstract:
In a harvesting machine including a crop intake arrangement that can be reversed in order to remove a jam or undesirable material, the crop intake arrangement including a crop intake-aiding component that is mounted for movement between a normal operating position, wherein it is located adjacent a path through which crop flows during normal operation for engaging said crop, and a non-operating position spaced away from said path, and an actuator coupled to said crop intake-aiding component for selectively moving it between said operating and non-operating positions, the improvement comprising: a sensor for detecting at least one of jam or undesirable material and producing a signal representative of said jam or undesirable material; and a control arrangement operatively coupled between said actuator and said sensor, and being responsive to said signal for causing said actuator to automatically move said crop intake-aiding component to its non-operating position before any reversal of the crop intake arrangement occurs, whereby said crop intake arrangement may then be reversed without any hindrance to the removal of the jam or undesirable material by said crop intake-aiding component.
