I saw a pic of one of these and they look like great mowers. Those controls look like they would be nice to use too. Anyone on here using these? What is the engine horsepower and deck size of the biggest model? The one I saw looked to be at least a 52" and couldnt really tell about the engine, but it did have a donaldson filter. What do these go for new? Plus the wheels and tires look to be bigger than my full sized WBs which are 18x8.5 I think, these may be a 20" on the Hustler? not sure, but they looked pretty big to me.
