Abstract
A vehicle, especially a tracked vehicle, which is turned by imparting a speed differential to the drive wheels on opposite sides of the vehicle, is provided with a control member or lever which cooperates with four control-pressure transmitters. The transmitters are oriented symmetrically with respect to the manually operated member so that in its neutral position all four of the control pressure transmitters are ineffective. Each of two opposite control-pressure transmitters are connected with one side each of the respective servomotors controlling hydrostatic transmissions for the wheels. The other two transmitters are each connected to the opposite sides of the servomotors.
