I have a 3720 Cab. The JD Cab is by far the best. I wrote a long review in the JD Tractor Review Section.
I am very happy with this whole tractor.
Heat works awesome, And now that we've had some warm days, I can honestly say that the Air Conditioning works awesome too....
Check Out my review, I told it like it is... it is very lengthy, nobody else has yet to make a cab as good as the JD's.
3720 with:
Cab, Heat, AC, Cloth Air Ride Seat, Arm Rests, Electric Hydraulic Divertor, Stereo, Auxillary Lights, Front and Rear Wipers, 300cx Loader, with extra Auxillary Hydraulics plumbed down the loader arms, Mid & Rear Pto. 73" Heavy Duty Bucket with reversible bolt on cutting edge.... Oh yeah and Vertical Exhaust is the greatest.
I'm ready for anything.... I didn't want to have any regrets later down the road, so I got all the options up front......
