Abstract
A hydraulic system for a work vehicle includes a first pump with a first swashplate providing a first flow in a first circuit and a second pump with a second swashplate providing a second flow in a second circuit. A supplemental pump with a supplemental swashplate provides a supplemental flow to a supplemental circuit. A first valve selectively enables flow from the supplemental circuit to the first circuit. A second valve selectively enables flow from the supplemental circuit to the second circuit. A controller determines to operate the supplemental pump in one of a standby condition and a use condition based in part on a first angle of the first swashplate and a second angle of the second swashplate.
