I think it's a two stage pump, but I don't know that much about hydraulic systems. Not sure if that can explain the extra 75 or so pounds of weight. It probably goes slower in the 7 ton mode. HF is a little bit of a gamble. Some stuff you know to stay away from. In this case, the reviews are pretty good. Having said all that, I still think I'd stay with the Ryobi/Homelite.
