Work Horse & Mule Harness Design & Function Part 3
from issue: 45-1
The tugs, from their attachment to the hames usually traveling back along the animal, best perform at an angle of 80 to 100 degrees to the line of the hames. If the angle is significantly less than 80 degrees the tugs may pull up and back on the collar, but only if the belly band is not adjusted properly. When it is, this will ‘interrupt’ an aggravated angle preventing the horse from being choked by a forward rocking collar. If the belly band is too loose it won’t hold the forward portion of the tug in line. As each and every horse’s angle of shoulder is different, and as the head-set of a pulling horse may be more or less down or up, these factors will affect the angle of the shoulder at work.
