Abstract
A hydraulic system for use in a work vehicle with a powered implement is disclosed. In one embodiment, the hydraulic system may include a first hydraulic circuit including a first hydraulic pump with a low pressure and low flow output, switch and valve; a second hydraulic circuit including a second hydraulic pump with a high flow and high pressure output, switch and valve; and a third hydraulic circuit including a third hydraulic pump with a high flow and high pressure output, switch and valve. The first, second, and third circuits each include an output selectively combinable with each other by an operator control which controls the switch and valve configurations. The hydraulic system has several configurations. A first configuration is selectable to provide low pressure and low flow output to the implement, a second configuration is selectable to provide high pressure and high flow output to the implement from one of said second and third hydraulic circuits, a third configuration is selectable to provide high pressure and high flow output to the implement combining the output from the second and third hydraulic circuits, and a fourth configuration is selectable to provide low pressure and high flow output to the implement from said first, second and third hydraulic circuits.
