Hence to alter the near horse's coupling is to take up or let out the rein on the other horse's draught rein.
DRIVING] Crossing Traces is the device of fastening the inside trace of one leader to the inside bar of his partner. The practice is resorted to with the idea of keeping the bars even when one horse is freer than the other.
