Seems like I'm posting a lot of questions on here lately about the tractor... But the other day, it was 102 degrees outside, high humidity. Had AC on full blast, had been mowing about 10 hours.. Was blowing hot air. Cleaned cabin filter, radiator, and grille best that could be done in the field. Let tractor sit and cool off for a bit. It still wouldn't cool, except about every 5 minutes you could hear and see by the RPM the compressor engage for about 15 seconds, and you would feel a little cool air.
Think this is because it was so hot, and some sort of thermal switch causing it to operate in this manner to prevent damage?
Maybe low refrigirant? I didn't see anything in manual other than to take to the dealer. Could I not use automotive fill gauge and regular 134a?
Anything else it could be?
What does everyone else do or use to clean filters, radiator stack, and grille when in the field? Short of just buying an air compressor to go on the truck or trailer... I'm not sure?
