My wife's uncle, just bought a new jd 5065. I tried to talk him into a cab for every reason in the book until I was blue in the face, but he just smiled and said "the papers are already signed"...
After telling me of his options, MFWD, powerreverser tranny, and the FEL, a cab option would have cost him a little over $7000. retail. I'm guessing he could have had it for about $6300 more.
Another equipment guy was in the office while I was trying to convince him and said "He wouldn't buy another machine without a cab after getting attacked by killer bees on a dozer". His buddy bought a new jd 7430 without a cab and spent 5 days in the hospital after getting a hundred stings. He won't even get on the tractor now. Sad.
