Like those hooks and agree tractors should come with purposely designed tie down attachment points. Had to make my own.
Rules vary but rubber tire equipment usually has to be chained using ratchet binders. While straps may meet the load requirement there are exceptions.
Do you have any proof of that law? I’ve never seen a restriction against using lever binders and the only restriction against straps I’ve seen is crushed cars. BTW I’ve had good luck with lever binders and wheels. It’s tracked equipment without any give where they don’t work good.
