I have two UTU tractors. Both are good runners. The 1950 has had the transaxle replaced has a swartz front axle. It is also not the prettiest machine out there. I am in process of installing a yetter power steering. My 1952 it not a museum piece but it is a decent looking tractor. It has had a loader on it at some point. they replaced the whole hydraulic system except the pump. The reservoir is larger and both valves have been eliminated. They were replaced by a modern single spool valve that does not require the of a moline cylinder. It also has a mechanical lift on the pto which I don't think is correct for 1952. I am thinking about playing musical parts. I want to make the 1952 an originally equipped usable tractor and make the 1950 a more usable accessorized machine. Would I have any foreseeable problems swapping the Hydraulic systems between the two of them? Will I need any gaskets or seals if I want to switch the reservoirs? Also should a tractor built in 1952 have a mechanical lift PTO? the cultivator rockshaft is the same as the 1950 which has a standard PTO. Thanks.
