1. A method of determining causes of performance deficiencies of an off-road vehicle, comprising:

  • determining whether the vehicle is in a full-pull condition;

    measuring a ground speed of the vehicle in the full-pull condition;

    determining whether the measured ground speed is below a predetermined ground speed value;

    measuring a plurality of key indicator values of the vehicle when the measured ground speed is below the predetermined ground speed value;

    determining whether at least one of the measured plurality of key indicator values is outside of a predetermined specification for the corresponding key indicator value;

    concluding that low measured ground speed is the result of a mechanical condition when at least one of the measured plurality of key indicator values is outside of specification; and

    concluding that low measured ground speed is the result of an operational condition when none of the measured plurality of key indicator values is outside of specification.
