Double check your prices on the Raptor. Everything I have seen shows the Kawasaki being only $100 more than the Kohler. I too looked at these models and had I gone with one I would have taken the Kawasaki because of the manual choke; less to go wrong. As for Big Dog, they appear to be a subsidiary of Hustler anyway, so it is likely that you would see similar performance and quality out of the two. The addition of the hour meter, engine guard, wider tires and premium seat are all worth the extra money for the limited. Have you considered the Aliens Ikon X? Available in 42" and 52". Both have fabricated decks, premium seats, hour meter and foot assisted deck lift. Plus, through April 30th they are extending the warranty to 5 years. These units are based off of the gravely and are very sturdy. 42" is a Kohler and the 52" you have a choice of Kohler or Kawasaki. All three is these are less than the 52" Raptor Limited. Just a thought.
