[AT] Chain grades

[Jim and Lyn Evans]

DOT says that it must be grade 70.  That being said, they also say that the
total working load of the tiedowns in any direction must be at least half
the total weight of the cargo.   So, 2 chains, 1 pulling forward and 1
backward would be enough in your case.  4 chains, though still illegal,
would be plenty to hold your tractor and more than most people would use.  I
wouldn't pull into a weigh station and ask their advise, but otherwise you
would be fine and no one will bother you.

Thanks for all the responses. I will at this point assume the chain is grade
30.  Is it legal to use grade 30 to tie down a tractor for hauling, this
would not be commercial use but just private? Would 4 chains (grade 30) be
sufficient for and 8N & box blade (3200-3500 Lbs)?

<Grade 80 and 90 chain is specified for use in vertical lift applications.
