Abstract
A hydraulic circuit may be used for controlling a plurality of hydraulic implements. The hydraulic circuit may include a first directional valve, a second directional valve, and a relief valve. A variable displacement pump may be fluidly coupled to the first directional valve, the second directional valve, and the relief valve. The hydraulic circuit may be communicably and operably coupled to a controller, and the controller may be programmed to selectably control the hydraulic circuit between a first operational mode and a second operational mode. Additionally, the controller may be programmed to actuate the first directional valve between an open position and a closed position and to actuate the second directional valve between a first open position, a second open position, a first closed position and a second closed position.
