Patent ID: 8667886

Claim:
A vehicle comprising: a chassis, a ground engaging device supporting the chassis, a hydraulic system supported by the chassis, the hydraulic system including a hydraulic cylinder including a housing and a piston assembly, the housing enclosing at least a portion of the piston assembly, the piston assembly including a piston head and a piston rod, the piston head including a bore-side surface and a rod-side surface opposite the bore-side surface, the housing and the bore-side surface defining a bore chamber, the housing and the rod-side surface defining a rod chamber, a pressure source in fluid communication with the bore chamber to provide pressurized fluid to the bore chamber, the pressure source being in fluid communication with the rod chamber to provide pressurized fluid to the rod chamber, at least one valve configured to regulate fluid communication between the pressure source and the hydraulic cylinder, and a control system coupled to the at least one valve to periodically alter the supply of pressurized fluid to the hydraulic cylinder based on a duty cycle the hydraulic cylinder in a a partial output mode, in which pressurized fluid is simultaneously supplied to both the bore chamber and the rod chamber of the hydraulic cylinder so that the pressurized fluid moves the piston assembly.
