Don't know about the price bump, but the new Tier 4 engine is a Shibaura. Same engine that's in the NH Boomer 3050 (and probably other NH models). Apparently, Mitsubishi wanted too much $$ for their Tier 4 engine.
I know that the NH guys rave about how great the Shibaura-made NH tractors were, so I don't think going to a Shibaura engine is a step down for LS.
I like the Shibaura builds... My old Ford commercial mower had a 3cyl 27hp Shibaura diesel and it was great... And my current Hustler Super-Z zero turn has a 25hp Shibaura diesel.
Shibaura made tractors for NH for many years, the only real complaints i know of are related to electrical issues.
With that said, I'm really happy with the Mitsu in my R4047... Seems like a real good engine so far.
