Wells,
While You are asking this I wonder if air is available for the sub-cut with cabs? Seems to me they would be plenty warm even with the doors removed on a 90 degree day.
There is someone on the forum; sorry I can not remember the name, whose tag line at the end of his messages reads “A cab with out air conditioning is just a greenhouse.” /forums/images/graemlins/tongue.gif
The Kubota's have air I think. I was wondering about gettting in and out of the cab and whether they were better suited for long mowing types of jobs or are they pretty easy to use if you have to get off and on alot.
