As much as I love my Cubs, screw 'em.... I WANT THAT LAWN!!!
I've mowed hundreds of hours with a 102, 127, 149 (probably over a thousand on this one alone), and 1650... NONE of them have even come close to that cut quality!
Dang advertisers...
edit: That said, I bet they're all giving a "normal" quality cut when they're all over 100 years old! I also believe the bit about the torture treadmill. I witnessed what International does to its trucks on the driving simulator first hand (imagine what 4 8" hydraulic rams can do to a dump truck with 10,000 PSI behind them... BRUTAL!!!).
