poorly said:I have even had the a/c unit re-charged last summer. It wasn't really too low but did take a little freon to bring to maximum effiecency. I was using the Montana 5784 a couple week ago and the tactor was not running hot on the temp gauge but, it wascooler outside than it was in the cab. I just think that for a a/c cab I shouldn't b sweating while using the tractor on a hot day and feel cooler outside the cab than inside?!! I now have 365 hours on the meter so the history continues to show issues that are continuing just as it did when I first purchased the unit. I guess that I am just disappointed in the performance of this tractor in the enviormental staus of comfort. I like the tractor otherwise. When the dealer told me it wasn't a john deere my reply was I guess I didn't ask enough questions before purchasing it, He told me I was just too damned picky!! I told him he wasn't the only tractor dealer in world!!
Sorry that's how it's working. You should have working air or at least a working dealer.
