Once upon a time way back in Nov. 2011, I had a brilliant $150.00 idea until it made things worse. On my 07
L3400 the rear wheels have 6, 5/8" square holes, I got some 5/8 carriage bolts 2" long or so, welded one 3/8" shackle's on each of them, stuck them in the 6 holes on the wheel, put the nuts on the inside loose. Then got some cheap 1/4" chain at HomeDepot, cut it up somewhere around 10-12 inches long +or-, attach one end of the short chain to the side tire chain with 1/4" shackle, then attach the other end of the short chain to the 3/8" shackle on the 5/8" bolt, all 6 pieces, and I kept the short pieces of chain tight-ish by going back a link if needed.
Now if everyone has followed me so far and hasn't fell asleep yet, focus and picture this. My tire is jacked up, I have my tire chains on tight, I have all the 6 short 1/4" pieces of chain tight, I took my impact wrench with a deep socket behind the wheel, tighten all the nuts up on the 5/8" carriage bolts. Now for the first time my tire chains were straight and stayed straight and stayed tight. The crooked tire chain virus was cured, I was happy happy happy, for a month anyways, but after a month of use my Aquiline Talon tire chains that I bought in 07 started breaking every time I went in the woods. I didn't like that at all, it's a real pain to loosen up chains, weld a link back in, after 6 times I took off my brilliant idea, and went back to crooked chains.
