I have to make an almost 90 degree turn with my trailer to get into and out of my yard. I wet the road down with water. It helps, a little.
In the past I’ve broken a couple of the links shown in the first reference picture. The first time I had to use a nut cutter and destroy the nuts to get the bolts out.
My brother-in-law has been an auto mechanic all his life and has a nice little machine shop - now a hobby - in a detached garage. He built me a couple of new sets from ¼” steel. So now I carry a spare set in the fiver, Pix #2.
