I liked the cab so well that I traded off the similar sized JD tractor that I absolutely loved just so I could have the factory cab. As long as I keep the rear air intake filter clean, I can keep it nice and comfortable in the low 70's in the cab with the outside temps over 100. /forums/images/graemlins/cool.gif
Others have heard me talk about plowing 30" of snow in the winter while having on a T shirt. As long as I didn't drag a lot of snow in the cab while getting in and out (bringing in moisture), the windows stayed perfectly clear. In the summer, at times I have to adjust the vents to not blow directly on the glass, or on really hot days the windows will fog. /forums/images/graemlins/shocked.gif
The cab is tight, the doors seal extremely well, and all is well. About the only thing I've heard of people doing to improve them, is taking to top off, and applying a layer of insulation to the underside of the roof. Even though I don't have trouble keeping it plenty cool inside even on the hottest days (keep the intake filter clean), I may add the insulation just to keep from loosing heat/cool. The cabs are great. JD said there was "no market" for a cab in my sized tractor (50 hp); now JD is sending me literature about their new cab tractors coming out late this summer. /forums/images/graemlins/wink.gif I guess better late than never...
