Two horses or mules working side by side are generally referred to as a team. The customary procedure for ‘driving’ them is to employ team lines which, fastened to the outsides of each of two bits, provides that the teamster may apply varying pressure. With experience, training and maturity, the teamster might learn to softly send messages to each equine, through light pressure at the corners of their mouths, as to preferred direction, speed, and halt.
