If you are talking about me among others, I failed to report of the quality of cooling. Does a good job but when you get out in the sun for a long time and are working hard, especially baling hay in the sun and heat, you get a lot of radiation into the cab.....like you would with all cabbed tractors unless you do something like put reflective film on the doors and windows which I considered.
However, an easier solution is to take a short break, pull up under a tree to the water hose, with the engine running, run over the radiator, ac condenser, and hyd oil filter coils for a few minutes to blow the dust out and drop the ambient temp. Shoot the cab, especially the top. Mine is red and is not insulated The AC unit is over my head, under the red outer FG cover When you crawl back into the cab you will be pleasantly surprised.
