While there is no disagreement that they are the same tractor class/size which is the correct size for me, the JD 4520 stats seems to be much different than the Boomer 3040. The Boomer 3040 is like a JD 4105 and close to a JD 4120. If NH would have had a Shibaura cab model with an updated HST, I might have stayed with NH.
HP
3040 = 40
4520 = 60
PTO HP
3040 = 33.2
4520 = 50
Engine Torque
3040 = 77 ft lbs.
4520 = 113 ft lbs.
Final Drive
3040 = Spur Gear
4520 = Planetary Gear
FEL - 400CX has a couple hundred pounds more lift than the 250TL.
Plus the 4520's HST is electronically controlled between the engine and the transmission and I am getting an economy PTO. I really like the technology the JD has to offer on the 4000 series tractors (however, Kubota has very good technology, I just do like them myself - personal preference). I know there are pluses and minuses to having more technology, but I like the technology especially when much of the technology has been used in the construction field for years. I also liked the JD when I test drove it.
I do think the Boomer 3040 is a very good quality tractor, but I am wondering what the parts availability will be like 15 years from now for the tractor and do I really want to deal with that issue. I have a better feeling that I will have better part availability for the JD in 15 to 20 years than the 3040, but I could be wrong.
In addition, based on our PMs yesterday, I am getting a few grand more for the trade-in value then what we discussed. The hit for me is really not that bad (is not a fleecing - that JD dealer offering me $14k was out of his mind, this JD dealer is much different), but it is still a hit nonetheless.
