Maker, from my position the view isn't as clear when comparing tractors that are that closely spec'd. As far as reliability the L series has been very good. Between the two models you mentioned, no "built in" common problems come to mind. I can't give you a good opinion as to which machine to choose, the guys on the board can give first hand opinions of both models from "real world use". From reading the board I have noticed one common feeling from most operators. If you have the $$$ to get the bigger machine, get the bigger machine.
