ABSTRACT:
An apparatus coupled to a work machine for assisting the work machine in removing a first layer of material from a second layer of material is provided. The work machine includes a work implement with a cutting portion. The work implement is elevationally movably connected to the work machine. The cutting portion extends in a direction transverse the longitudinal axis of the work machine. An electromagnetic unit, connected to the work machine, delivers electromagnetic radiation towards the surface, receives a reflection of the delivered electromagnetic radiation, and delivers a responsive first signal. The electromagnetic radiation penetrates the first layer of material and reflects off of the second layer of material. A controller receives the first signal, determines the distance between the electromagnetic unit and the second layer of material and responsively produces a distance signal. An implement controller receives the distance signal and responsively actuates the work implement relative to the frame.
