1. A method comprising:

  • determining a desired trajectory of at least two auxiliary machines based at least in part on a desired work path or an alignment of a host machine and the auxiliary machines, wherein each of the auxiliary machines are coupled to a first side of an implement and the host machine is coupled to a second side of the implement;

    determining a first actual trajectory of each of the auxiliary machines;

    comparing the desired trajectory of the auxiliary machines to the first actual trajectory of the auxiliary machines;

    when the first actual trajectory does not satisfy a threshold distance of the desired trajectory, selecting a trajectory-assist mode;

    in response to the trajectory-assist mode being selected;

    crab steering each of the auxiliary machines toward the desired trajectory while a course of the host machine is different than a course of the auxiliary machines; and

    at least one of

         1) controlling a first one of ground engaging elements of each of the auxiliary machines in one of a free-wheeling mode, a minimum-slip mode, or a braking mode and controlling a second one of the ground engaging elements in another one of the free-wheeling mode, the minimum-slip mode, or the braking mode or

         2) applying a first amount of power to the first one of the ground engaging elements and applying a second amount of power to the second one of the ground engaging elements.
