Flow management of a hydraulic system

A hydraulic system for a work vehicle comprising:

• a first pump having a first swashplate, the first pump providing a first flow in a first circuit to a first plurality of selective control valves, the first circuit having a first pressure;
• a first load sense circuit connected to a first load sensing compensator of the first pump, the first load sense circuit having a first load sense pressure;
• a supplemental pump having a supplemental swashplate, the supplemental pump providing a supplemental flow to a supplemental circuit, the supplemental pump operating at a lower flow in a standby condition and a higher flow in a use condition, the supplemental circuit having a supplemental pressure;
• a supplemental load sense circuit connected to a supplemental load sensing compensator of the supplemental pump, the supplemental load sense circuit having a supplemental load sense pressure;
• a first supplemental valve having a first position preventing flow and a second position allowing flow from the first load sense circuit to the supplemental load circuit, the position of the first supplemental valve based in part on a first pressure differential between the first pressure and the first load sense pressure;
• and
• a first valve selectively enabling flow from the supplemental circuit to the first circuit when the supplemental pressure is equal to or greater than the first pressure.
