Abstract: A multiple row sugar cane harvester having automatic and independent control of multiple base cutters utilized to severe sugar cane stalks in adjacent rows. Position sensors sense the height of the base cutters relative to the chassis of the sugar cane harvester and feed the signals to a controller for adjusting the height to a preselected level. The base cutters are individually driven by hydraulic motors through individual hydraulic circuits and the operating pressure is sensed and fed to the controller for determining whether a choke condition exists. A load sensor is incorporated between the linkage and the sugar cane harvester chassis for determining whether the base cutters have ground contact to elevate the base cutters.

Abstract: A method and apparatus for controlling a height of an agricultural equipment component is described in which an average crop height is determined. In one embodiment, the agricultural equipment component is controlled to maintain a predetermined distance from a current top of crop level. If a current top of crop level cannot be determined, a virtual top of crop level is calculated using the average crop height value. The agricultural equipment component is controlled to maintain a predetermined distance from the virtual top of crop level. In another embodiment, the agricultural equipment component is controlled to maintain a predetermined distance from current ground level. If a current ground level cannot be determined, a virtual ground level is calculated using the average crop height value. The agricultural equipment component is controlled to maintain a predetermined distance from said virtual ground level. An ultrasonic sensor is also provided.

Abstract: A harvesting vehicle includes a header having a cutter bar, a crop transport draper and a reel mounted above the cutter bar to sweep the crop to the draper. The operation of the header is autonomously monitored and controlled to reduce operator loads or to run autonomously by detecting: reel wrapping; differential rates of flow of crop on the header at different locations; where the crop to be cut is at least partly lodged so that stems of the crop are not vertical; the presence of a crop streak of uncut or poorly cut crop behind the cutter bar and/or a band of disturbed soil behind the cutter bar. The detector is arranged to control ground speed, header height, reel height and operation.

Abstract: A tractor has hydraulically driven wheels at a cab end and castor wheels at an engine end. It can be driven cab forward in a working mode with a header on the forward end. It is rotated to engine forward in the transport position for more stable higher speed travel. There is provided a float module with adjustable and calibrated springs on the header which allows the header to float relative to the lift system on the tractor. The float force is adjusted by raising and lowering the lift system in dependence on an angle measurement of the lift position. The lift system includes a lift cylinder and tilt cylinder controlled to change cutter angle while maintaining a sight line to the cutter bar for the operator.
