Friend has a MF 4243 cab tractor and he thinks it needs some freon added. This tractor was made from 1998 thru 2001. Does anyone know what year tractors came with R134A freon?  Thanks for any help.

If was 134 factory it will have 134 fittings. If it has 134 adapters on 12 ports its been switched. It is possible to charge 134 through 12 fittings if you the right pieces.
