I am in the market (finally) to buy a new mower. I want the Scag Tiger Cat with 19 horse Kawi with 48" deck. The dealers around here are selling them for $6999. One dealer has a demo with less than 50 hours for $6300. This demo will still have the full factory warranty on everything. Is this a good deal for a demo or should I spend the extra $700 bucks on a new mower? Does 50 hours make that much of a difference in price savings? Thanks for your help.
