Abstract

A tandem running gear on a self-propelled agricultural machine, in particular a combine, where in the front a drive axle (1) and on both sides thereof swing arms (3, 3A) are disposed under the chassis (2). The swing arms (3, 3A) can be charged by hydraulic work cylinders (8, 8A) in such a way that a respectively preset wheel load distribution between the drive wheels (5, 5A; 6, 6A) and the steered wheels (7, 7A) is attained using a measuring and control device for the hydraulic device.
