My dad and I are looking to build a u puller, we have a ub in our sights we are wondering if it would be the right move, wondering about differences in utu vs Ubu, pros cons etc. any advice would be appreciated. Or if anyone is looking to sell one built already we may be interested.
 
I have a UTS with a good running 450cid engine that is already in it. It is a short jug engine, so it will be legal for anywhere you want to go. The tractor just needs to be setup with wheels, tires, weight brackets & paint. Have the recipts on the engine. $3500.

Thanks,

Generally as you move from the early U (1939) to later models and on to the UB, transmission housings get heavier. Early U models had 1st & 3rd gear in opposite spots of post 1947 models. including G models, there were several axles, housings, bull gears, ring & pinions, constant mesh, etc. Some veteran builders can set you straight on the tranny specifics. Most guys prefer sitting on top and using a foot clutch, so the UB is more sought after. Generally, a mid forties U of the one piece block type is a good start. They are abundant, have faster gears, lighter castings, and cost less. Good start if you plan on installing a whole different engine. 450 cubes is a pretty standard do-it-yourself size requiring no sleeving, crank welding, extensive clearancing, etc. Also, bore and rebuild a 403 engine and with minimal work, it will bolt right in at 436 cubes. HD800 blocks are your next step up for the $$$....
