JR, welcome to the forums. First of all do you need a 54" deck? If not you can buy a YTH24K48 that has a deck like this with a 10 yr warranty. Also this mower has the K57R trans from TuffTq. It's the fast tractor from Husqvarna and this thing will move for a rider. It also has the 24hp Kohler Courage Twin cylinder engine that has pleanty of tq. as well. I am very satisfied with my mower that has around 16 hours on it so far. I guess if I was going to pay $1700 on a mower I'd take a look at a local Husky dealer or a trip to your local Lowes and look at what they have to offer. Also look at the reviews online at the mowers from the lowes web site and from Mowers Direct.com
Also if you buy with the Lowes Card you get 5% off and that brings the YTH24K48 down to $1799 new.
Here's the deck. It's reinforced.
