Abstract
Abstract To correct lateral tilt of a sugar cane harvester, caused when the elevator at the rear of the harvester is swung to one side or the other, the rear wheels of the harvester are carried by a common axle which at one side is pivoted to the corresponding side of the main frame about an axis longitudinal with respect to the harvester, the other side of the main frame being raised or lowered, to correct tilt, by a hydraulic cylinder connected between the main frame and said pivoted axle.
