Like any of them if you keep the radiator/condensor/intake filters clean and proper Freon/pag oil levels the climate controlled cabs might no freeze you azz off, but they beat eating dust and wiping the sweat. Also on mine every 3-4 years I take the shell off the top of the cab and clean the evaporator/vents/fan out. Driving a tractor in a dusty field is not like driving your F250 up and down a paved road. A tractor AC is more about maintenance and a lot get neglected. A neighbor complained about his Kubota AC and I took one look at the condenser and it was completely plugged. If no air can get between the cooling fins it is not going to cool very good. The older Kubota's have very small fins on their condensers and are more prone to plug, newer one have wider fins. If kelp clean they work just as good.
