In one aspect, a method is disclosed for automatically controlling a position of an implement of an agricultural work vehicle relative to a ground surface. The method may include monitoring, with one or more computing devices, an implement position parameter indicative of the position of the implement relative to the ground surface. The method may also include calculating a normal output signal based on the implement position parameter. The method may also include determining when a boost condition is satisfied based on a comparison between the implement position parameter and a predetermined implement position parameter threshold. The method may also include computing a boost output signal based on the implement position parameter. The method may also include adjusting the position of the implement relative to the ground surface based on the normal output signal and the boost output signal.
