That's a real nice tractor and it made my short list when I purchased mine last summer. If you are doing a lot of haying make sure the 12 speed will be enough to run your hay equipment at optimal speed. It will get-r-done but it may be a little aggravating. The 540/540e is nice (I think it's really a 540/750 PTO) and I only shifted it in 3 or 4 times with a rotary cutter and it seemed fine. Just make sure you don't plan to purchase any 1000 rpm equipment in the future. The NH Buddy seat is sweet!
I liked the lay out of the cab and there was something about the parking brake that was a little different. I almost think there wasn't one but the gear selector was placed in a certain position. (?) I can't remember exactly, getting old sucks!
I went with the other blue tractor because of the 40f/20r speeds, electronic hi/lo, 540/750/1000 PTO, more hp and a couple standard features that I felt NH or the dealer were being a little crazy on the pricing. The rear wiper and third remote was over 2K but came standard on the LS.
Happy tractor shopping and post pictures when you get your tractor!
