Bought Another Gem

[wukong]

As if I did not have enough problems I just bought an old Massey Ferguson that needed a home. I purchased this one for $800. The serial # appears to be 9A 121605 and it has a 4 cylinder diesel engine that runs. A former owner seems to have recently changed the head gasket as it appears to be clean copper. I believe that the valves are not adjusted properly as it appears to be skipping and has low power. It will move in reverse and was able to be backed on a trailer with assistance. I would appreciate assistance in identifying the year and model so I can purchase parts.

Industrial - no 3PL or PTO. Also a seriously-sized machine. I can see a "50" sticker - suggests MF50

However it appears to have had a backhoe fitted - or at least the mounts for one are provided. Coes it still have its loader?
Can we see a few more general-view pics please?
Is the transmission clutch and gearbox, or F-R lever (or pedals) and torque converter? If it's the latter, it's problem maybe as easy as low transmission oil.
