Abstract

A system is disclosed for controlling the slope of an earth working machine which is propelled by at least four support means, for example tracks or wheels, wherein the slope of the distortable machine frame is adjusted with respect to these support means and wherein the control system particularly comprises a slope sensing means for controlling the slope across the rear end of the frame of the vehicle and a torsion sensing means for controlling the slope across the front end of the frame of the vehicle.
