The conventional circuits for tractor loader backhoes generally consist of fixed displacement pump and valves that bypass excess flow resulting in poor efficiency. Poor machine controllability, high operator actuating forces, lack of pressure compensation and other problems have warranted development of better hydraulic circuits. These and many more handicaps are overcome in Vickers new design of sectional directional valves assisted by a load sensing variable displacement pump. An overview of possible alternate circuits is presented here with a description of the features of a new CMX sectional valve and its application in a tractor loader backhoe circuit.
