Abstract: A work machine is often used to spread material from an initial location across a wider area. It is desirable to raise and lower a work implement of the work machine such that the material can be quickly and easily spread to a uniform or otherwise desirable thickness. The present invention provides a method and apparatus of automatically controlling the position of the work implement. The automatic implement control system of the present invention lowers and raises the work implement based on at least one of a directional characteristic of the work machine and a position of an operator input device. The work implement is then automatically lowered or raised to the desired position to facilitate an efficient work cycle for spreading material.
