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.
