Dont know, my Zetors dont have Airco, only AWCO (All Windows Can Open) 
but R134a is the most widely used refrigerant, since CFK containing refrigerants were phased out in the early 90's before the Super series came into production in 1997. So it is very likely (99% certainty) that it uses R134a.
To be sure, check the manual what refrigerant and what charge the system should have.

I just repaired and recharged the AC on my 6341, and I used 1.8 lbs of R134a. After soldering the leak in the condenser (Zetor neglected to stabilize the hoses with a clamp, and the vibration cracked the condenser), I used a vacuum pump to evacuate the air and moisture, then recharged with the R134a. My tractor has a decal on the lower front cab window that specifies the amount of R134a to use. Maybe yours does too?
