I see what you are thinking, its an idea, but securing your machine will be difficult. I think the Uhaul you are referring to is called a JH, my dad rents them out so that's how i know. I'm pretty sure it will take the weight on well since we occasionally store wood stoves in Uhauls which can weigh near 1k pounds depending on which one and we load the trucks to the max. If you do go this route, i would suggest tying the tractor down in some way, putting blocks under your tires so It cant move forward or reverse in transport, and getting the uhaul insurance for your cargo. Another idea is renting a uhaul car trailer but I'm not sure if your tractor will fit due to the width of the ramps on the trailer since the middle is just hollow and deck-less. Or you could hire a hotshot (pickup and flat bed trailer) to transport your machine. It cant cost that much to go 350 miles especially with such a small tractor. Probably call around different trucking companies and getting rates to see whether having a hot shot haul it is cheaper than a uhaul.
