There was a bolt hole at the top and I drilled another at the bottom, had enough clearance that the loader does not hit nuts on backside. 1" bolts and nylocks worked great.
don't the chains knock around and drive you crazy in those pvc holders? no, the tractor doesn't ride like the Buick, but to avoid a lot of clanging, i'll just drive to the shed to get the chain when needed. I don't run far distances nor have lots of call for impromptu chaining anything usually. neat ideas, but wary of the clanging!
The other day I tie-wired some antifreeze jugs to the box blade... has worked out ok so far. Easier than wrapping chains around stuff and hopin they stay put. Short term fix... quick and free!
