I just purchased the Fastrack SD 54/25. I could not be more pleased. The flex forks make the ride very comfortable, and I can flat cut grass. Probably twice or three times the mower I need for the less than 2 acres of level yard, but using a superbly designed piece of equipment and one with high build quality gives me satisfaction (as the Rolling Stones can't say). Based on my 3 hours of use (four cuttings), I expect this to be my last mower. Thanks Hustler for providing a product that has exceeded my expectations.
