Well . . ., now with that word "necessity" in there, I'll agree with Cowboydoc, but otherwise . . ./w3tcompact/icons/wink.gif
Unfortunately, nearly all my hay experience has been on an open tractor and it can be pretty darned miserable at times in the heat of the summer, especially if there's any breeze at all because when the breeze is coming from behind you and you have dust, tiny bits of grass, etc. blowing down the back of your neck, in your eyes if you look back (unless you wear eye protection which adds to the heat discomfort), and things like that. I did just a little baling with an air-conditioned John Deere and the difference is wonderful!.
