A hydraulic system includes a first hydraulic circuit and a second hydraulic circuit. The first hydraulic circuit includes a hydraulic cylinder assembly, a pressurized fluid source, a fluid tank, and a metering control valve. The hydraulic cylinder assembly includes a cylinder, a rod, a head end including a head pressure, and a rod end including a rod pressure. The metering control valve includes a rod extension position, and a rod retraction position, and is fluidly connected to the head end, the rod end, the fluid source, and the fluid tank. The second hydraulic circuit includes a second circuit valve assembly selectively fluidly connected to the head end, the rod end, and the fluid tank.
