Abstract:
A user interface for a position adjustment apparatus that controls the position of a position adjustable header implement relative to a surface, the interface comprising:a means for processing input data for selecting between and incrementing a stubble height mode and a pressure compensation mode of operation of the position adjustment apparatus, wherein the position adjustment apparatus positions the header implement in response to an output signal generated by the means for processing input data to maintain a selected stable height position or a selected compensation pressure; a mode control switch for inputting data to the means for processing input data, wherein the mode control switch permits selective activation of either the stubble height mode or the pressure compensation mode; a first increment key for inputting data to the means for processing input data, wherein the first increment key permits positive or negative incrementing of the mode selectively activated by the mode control switch; and wherein the mode control switch activates the mode selectively activated from the group of modes consisting of a stubble height mode and a pressure compensation mode, so that a first pressing of the first increment key results in the switch activating the stubble height mode, the user interface further comprising a second increment key for inputting data to the means for processing input data, so that a first pressing of the second increment key results in the switch activating the pressure compensation mode.
