1. A traction control system for a machine having an electric drive configuration, comprising:

  • an electric motor associated with at least one wheel and adapted to provide braking torque to the wheel; and

    a controller configured to;

    determine a rotational speed of the at least one wheel;

    compare the rotational speed to an allowable slide threshold, wherein the allowable slide threshold is based on a ground speed of the machine, wherein the allowable slide threshold is a percentage of the ground speed of the machine; and

    adjust the braking torque to the at least one wheel during retarding if the rotational speed is less than the allowable slide threshold.
