That's a Ford tractor from the late 50s to mid 60s.
Three forward speeds and one reverse (one speed gearbox)
There should be two levers on the RIGHT side of the seat to control the lift arms. One controls height and the other one controls the speed of response.
The PTO w/o shield is fine. Implements like a rotary cutter or mower will have a shield on the PTO shaft. You should be fine.
There should be a lever on the LEFT side of the seat down on the transmission to control PTO. There are two settings. One is "ground PTO" which only turns the PTO at the same speed as the wheels. This would be used for operating a hay rake. The other setting turns the PTO at the transmission speed. At full throttle that should be about 540 rpm.
The key thing with the old Fords is whether or not it has "live PTO" or not. If not, you will need to buy a "PTO override". You can figure this out by pushing down the clutch pedal (left side). If it feels like it has two stages, then you have live PTO.
Feel free to email me. I learned all this the hard way about 15 years ago when I bought a tractor. I spent a lot of money, a lot of time, and a lot of skinned knuckles, but I know how my tractor works.
One other thing: Ford tractors from that era are knockoffs of Massey-Ferguson designs and many of the parts are identical.
