My Lazy straps are 1″ light leather straps about 18″ long….. I have used nylon rope. They are adjustable, but not conveniently. They are entirely inconsequential to me. All they do is catch the hold-back when I unhook the yoke. I immediately upon unhooking, hook my hold-back up into the ring at the top of the lazy strap…. no need to let them hang.
I also hook them tight in a two-way, and back them to get the slack for the evener to roll. I am not so sure that there is a lot of tongue weight on a riding plow anyway, the problem is to maintain collar position, and if the straps are too short the pole could be causing the collar to shift during motion.
