the yoke on the pole

For horses to hold safely and comfortably, the pole must extend about 20 cm beyond their nose line. If the length of the pole is to be reduced, it is necessary to place a yoke at its end. Its size must be such that the small chains keep the same angle as if the pole had not been shortened. In the extreme case, the yoke placed at the level of the collar will have the same length as the main singletree of the vehicle. This is the size recommended with American collars.
