My Cub has a Kohler 20.5hp one cylinder engine, 46" deck, and automatic transmissin, power steering, and cruise control. It also has a cup holder, and a map holder (?). I got this one because it has a Kohler, and I've had a lot better luck with them than the Briggs engines. It was the best one I could get without going imto the industrial version.
The first tractor I had was a Cub similar to Karl's. It had an 8hp Kohler with generator start and electric PTO. After I ran that to death, I got a Sears Suburban 12hp, followed by a Ford LGT165. That Ford was the biggest POS I ever saw. It was equipped similarly to my current tractor, but was in the shop more than it was being used.
