ABSTRACT:
An implement control system is provided for controllably raising and lowering an implement relative to a work vehicle. The implement is pivotally connected to the work vehicle and movable between maximum raised and lowered positions in response to the extension and retraction of a hydraulic cylinder. The implement control system is operative for controllably connecting the hydraulic cylinder to a hydraulic accumulator as the implement reaches its desired position, thereby slowing movement of the implement in a smooth manner.
