And to make it even more confusing, it is my understanding that LS is no longer building the new compact tractors for New Holland. I read that New Holland went back to Shibaura for their new tractors. Apparently, NH realized that consumers had wised up and didn't want to pay several thousand more for the same blue tractor that said "New Holland" on it than for a blue one that said "LS" on it.
And now LS is using Shibaura diesels in their compact tractors instead of Mitsubishi engines. Apparently, Mitsubishi raised the price on their Tier 4 engines too much for LS. The Mitsubishi engines were great engines, but that doesn't mean the Shibaura engines are a step down. Apparently, Shibaura makes a darned good engine too.
Buying a tractor is much more confusing than buying a car. I shopped for months, and the more I shopped the more undecided I became. I finally decided there wasn't much difference between the ones I was looking at and I went with the Kioti DK50SE HST. I could have been very happy with the LS, Kubota or Deere also. They are all good, but there is no "perfect" tractor. Go drive a few of them. Find one you like at a dealer you like, and buy it.
