I did a quick comparison to the Raptor sd 42 and the two differences I see are the raptor has 2 blades instead of 3, and weighs 73 lb less than the Ariens. 587 vs 661 lb. 74 lb. is quite a bit of extra something. I will take a look at it for a better comparison. Keeping my options open. What's better 2 blades or 3? The Ariens only comes with a Kohler where the gravely you get a choice Kohler or Kow. I did get a good quote on the Ariens for $3,500 +tax.. Thanks again for everyone's input.
