LS started selling tractors under their own name in 2011 in N.A. Before that they built tractors for several other companies and probably still do (I believe some of the NH boomers). One of the LS guys can probably say which ones for sure.
I'm pretty sure it was actually 2009.
The NH Boomer 50/40/35/30/25/20 and Case/IH Farmall B 50/40/35/30 models are LS products. Case and NH do use a different FEL that has quite a bit less lift capacity, and breakout force, but somewhat higher maximum height.
