I recently purchased a Raptor SD 54" and have realized that I want a step or two closer to commercial for what I'll be doing with it. The dealer I bougt it from is willing to give me back what I paid less $100 on it which I feel is extremely fair and the new mower a 2014 Fastrak SD for $6499. What are thoughts on the pricing with this? He also pointed out that it has the FX engine, and the chain suspended deck, both of of which I like.
