Late model Gravely 7.6hp with 30 inch rotary mower and dual wheels. The LI has the best combination of ground speed and blade tip rpm's in my opinion for rotary mowing in high gear. And it has enough power & torque to run the 30 inch rotary mower at rpm's just a tad above idle in this (and most) applications. This machine is kind of a hybrid, a non-smoking strong 7.6 hp motor atop an older LI. I picked it up for sixty dollars,,,had to install a driveshaft (see my pictorial video) an air filter assembly, it came with a 30 inch mower.
