Patent Number: 231646

Application Number: 506/DEL/2002

Abstract:

The invention relates to a hydraulic system for load compensated control of agricultural implements hitched to a tractor, which shows the problem of non-smooth and jerky movements under varying load conditions during lowering or lifting of agricultural implements hitched to the linkage end of a tractor. This is made possible by incorporating a six-way five position spool type direction control valve, having in-built flow control facility, in the hydraulic control system resulting in a novel integrated load compensated control system capable of providing smooth and non-jerky movement in an energy efficient manner to agricultural implements hitched to a tractor.
