Hello all, I have a concern with my cab A\C. It does not seem to cool the cab very well. Yes, I checked and cleaned both filters, air flow does not seem to be an issue. Have flipped the Recirc and Fresh level with no change. I have a R-134a machine therefore I also verified proper charge. Now I am wondering if Kubota undersized the compressor to compensate for the small engine? Yes, I do realize this thing is a small greenhouse on wheels. Also, I use this tractor at night so some window tint is not really feasible(have enough trouble seeing at night). Just wondering what others have experienced with their tractors(cab owners only).
