Securing Tractor to Trailer

[MoMower]

The axle straps that hook to themselves are the quickest and easiest, and legal I’ve found (in PA), but I have a much smaller machine then the OP.

I use 5/16 gr 70 with latch hooks on my trailer d rings, 2 in front, back up for tension, then 2 in back on the hitch tighten with ratchet binders. Yearly trip 270 miles each way over heaved northern New England roads, nothing has moved thus far.
