John,
I'm not familiar with the Mass. Pike, but I would pay $5.00 to watch someone drive a tractor that far! :thumbsup::laughing:
UHaul rents 'car haulers'. They are not flatbed trailers per se, instead of a floor they have two channels that the car's tires ride in. If you tell the UHaul people you want to haul a tractor on it, they may not rent it to you.
The trouble is, the multi load guys have to find other stuff near where you want your tractor picked up, that has to be delivered near to you. That's easier said than done. I would want around $400.00 for it. By the time you factor in fuel cost, plus at least 6 hours of time (2 1/2 hours one way, 1/2 hour to load and chain down, another 1/2 hour to unload and clean up), I'd be surprised if any commercial hauler would do it for less. What you might do is look for a used, 16' utility trailer. Most of them have a 7,000 lb GVWR, and I see them on Craigslist here for $700.00 or so. You said the tractor weighs 1,900 lbs. You could buy a trailer with a single 3,500 lb axle and probably be just fine to haul it yourself. My 6x12' trailer weighs 1,000 lbs, leaving 2,500 lbs for cargo.
