Patent ID: 8051651

Claim:
An hydraulic system to power an implement associated with a support vehicle, comprising: a first hydraulic circuit including a first hydraulic pump with a low pressure and low flow output, a switch and a valve; wherein said switch and valve control the flow path of said pump; a second hydraulic circuit including a second hydraulic pump with a high pressure and high flow output, a switch and a valve; wherein said switch and valve control the flow path of said pump; a third hydraulic circuit including a third hydraulic pump with a high pressure and high flow output, a switch and a valve; wherein said switch and valve control the flow path of said pump; an operator control mounted to the vehicle at an operator location to selectively control said switches and valves to control the combination of said flow paths to achieve configurations of desired pressure and flow supplied to a powered implement; wherein a first configuration is selectable to provide low pressure and low flow output to the implement from said first hydraulic circuit; wherein 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; wherein a third configuration is selectable to provide high pressure and high flow output to the implement combining the output from said second and third hydraulic circuits; and, wherein a fourth configuration is selectable to provide low pressure and high flow output to the implement from said first, second and third hydraulic circuits.
