Abstract
A main valve and method assembling for use on a machine is disclosed. The main valve may comprise a body, a free wheeling valve, a bypass valve, a flow divider valve, a free wheeling pilot valve, and a flow divider bypass pilot control valve. Each valve may be disposed inside the body. The body may define a plurality of ports and channels between the valves. The free wheeling valve may be operable between a free wheeling mode and a drive assist mode. The bypass valve may have a flow dividing mode that permits fluid communication between the free wheeling valve and the flow divider valve, and a bypass mode that permits fluid communication between the free wheeling valve and first and second bypass channels.
