1. A method of managing excessive slippage at a physical interface between a machine and a traveled surface, the method comprising:

  • determining a track force, the track force being indicative of a propulsive force exerted by the machine on the traveled surface;

    determining a modeled slippage based, at least in part, upon the track force and a slippage model; and

    conditionally causing a reduction of power output to drive components, by a motor, based upon a comparison between the modeled slippage and a slippage limit.
