Gordon -
Nice work on the hitch modifications. It reminds me that I really need to work on my welding skills.
I find I seldom use the drawbar on my tractor for just that reason. I end up using a draw bar that goes between the lower 3 Pt hitch arms.
I do hope you and Piston will keep us up to date on how your Provnost trailers are working out.
I'm still nosing around for a solution that will work for me. I'd love to find something that is 4' (or maybe 5' max at it's widest point) and maybe 8' long that is rugged enough and has good ground clearance for use in the woods, but is still street legal. I don't have to go far or fast (typically less than 5 miles on roads with speed limits ranging from 30-40 mph). I typically just take my unregistered, non-dumping trailer out on the back roads and hope no one stops me. (I suppose I could make the argument that I'm legal since I have the SMV triangle, and it's "ag business", since the USDA considers forestry a type of agriculture, but I doubt I'll win that argument if it comes down to it)
