ABSTRACT:
A skid steer vehicle has a chassis with four drive wheels suspended from the chassis that are damped by four damping cylinders. An electronic controller varies the damping of the cylinders in an automatic mode, based on certain operational parameters of the vehicle, and in a manual mode in response to operator selection of a desired degree of suspension damping.
