Tractor Air Conditioning

I bought a 90 something model Agco-Allis tractor. I suspect it may have used the R12 refrigerant.
What is involved in switching it over to the R134a?

I never converted one but im sure its the same process as a vehicle and found this hope it helps. We still use r12 in ones that came that way.

I've just drained all the oil out of the compressor, changed out the receiver/drier, vacuumed the system down good, charged it up with ester oil and the correct amount of R134A, and went on my way. Done 3 or 4 like this and the air gets plenty cold.

I think thats the same thing that link said for the most part.
