A hydrostatic steering unit was designed for agricultural tractor and its performance was evaluated at different values of front wheel inflation pressure and toe-in under stationary condition. In field condition, tests were performed at different values of front wheel inflation pressure, toe-in, front axle load and forward speeds. The hydrostatic steering performance was also compared with that of mechanical steering under the above conditions. The steering effort of hydrostatic steering was observed to be only 1/8th of the mechanical steering.
