Abstract
In a switching arrangement for the hydraulic drive of a full-track vehicle, in which arrangement at least one drive motor is associated with each respective endless ground-engaging track at both sides of the longitudinal axis of the vehicle, there are provided for the drive motors located at both sides of the longitudinal axis of the vehicle, a common source of pressurized fluid and a valve arrangement by which the drive motors can be connected with the common source of pressurized fluid in series for moving the tracks in the same sense and in parallel for moving the tracks in a mutually opposing sense, and by which each drive motor can, if required, separately be supplied with pressurized fluid.
