At the risk of being flamed for “I told you so”, now is not the time to criticize for this accident. I have seen too many posters on this forum say they have enough trailer to tow their tractor & can’t see spending any more than necessary to do so. Their justification is “I am not going that far.” Most of the posts discuss about how much the trailer can hold versus the weight of the tractor, but nothing about the placement or equalizing the load. Making sure of proper amount of tongue weight, trailer length, single or tandem wheels, brakes, sway control, tow vehicle wheel base, load capacity, etc. I was once one of those who thought what I had was enough trailer & after splattering the load all over the road, jack knifing the trailer, & bending an axle on the truck because of improper loading, I now have trailers equipped with breakaways, brakes, spare tires & are the proper weight & length for the load, along with a tow vehicle designed for towing. I cannot fathom how someone can spend over $20,000 for a tractor & not spend a fraction of that for a proper trailer to protect your investment.
Egressman best of luck recovering from this, been there done that, & have the T-shirt.
