The heavy-line horse is hitched correctly. Dotted line shows same horse with hitch raised at "A" to accommodate a short hitch. If the dotted line horse were hitched same as heavy line horse, an up-pull on beam would result. Too long tugs have an opposite effect. Raising or lowering the clevis at point "A" corrects line of draft from hame to point "B".
