ABSTRACT:
A hydraulic system with dual pumps for tractor brake, steering, and loader valves wherein one of the pumps is connected directly with the tractor brake valve, and the system is arranged to have the hydraulic flow go from the brake valve to a pressure compensating valve which is connected with the steering valve, and the other pump is also connected with the pressure compensating valve and thus with the steering valve. As such, the output of both pumps can be directed to the steering valve and subsequently also to the loader valves which control the earth-handling bucket and clam and the like.
