ABSTRACT:
A system and method for determining a position of a work tool of a work machine is provided. A desired surface configuration for a geographic location is identified. A mode of operation for the work machine is selected from one of a first mode and a second mode depending on surface configurations. The position of a work tool mounted on the work machine is sensed and the rotational angle of a swing assembly mounting the work tool is sensed. The location of the work tool is determined relative to the surface configuration based on the sensed position of the work tool when the work machine is operating in the first mode. The location of the work tool is determined relative to the desired surface configuration based on the sensed position of the work tool and the sensed rotational angle of the swing assembly when operating in the second mode.
