Abstract
A hydrostatic transmission vehicle which is direction controlled by a speed controlled running assembly known as a motor-director running assembly and which has at least one further speed controlled driving running assembly. The motor-director running assembly is pivotable by means of a direction control system and its speed control system is coupled with that of each driving running assembly so that a speed which is coordinated with each driving running assembly is automatically applied to the motor-director running assembly when the vehicle is travelling in a straight line or turning.
