I have a question that hopefully someone here can answer. I was just looking at the commercial mowers on Snapper's website. Can anyone tell me the difference between GROSS torque, and NET torque? They offer the B&S engine with 8.5 gross torque, and the Honda engine with 7.1 net torque @ 2500 RPM. Just curious which is really the stronger engine. Also, maybe its been a while, but I thought the usual engine RPM setting for mowers was closer to 3000 with 3200 being the absolute maximum. Have safety ratings brought the RPMs down?
