You'll like that machine. I've got 3 of them now, all the same-61 inch deck, 35hp Briggs big block. Great machine, lots of power and not all that bad on gas.
Just a word of advice/warning, and they may have fixed it in recent models, but on ours one of the fuel lines that goes into the vacuum pump on the top of the engine block runs over something instead of under it (or the other way around) and because its routed that way it is a hair short and over time works its way off the nipple of the vacuum pump. This allows a little air to mix in and the vacuum end of things just doesnt work the way it should. Shuts down the engine and its near immpossible to start unless you figure that out. Just check it out now and be good to go.
