I have the gravley, and like the others will say its a great little mower. As far as engine choice I would say its a matter of preference (who has had luck with what), I prefer Kohler. But, I would say what ever you do, dont get the dixon. I know nothing of dixon, but dont ever ever get a new mower. Exmark is the best, or right up there, but remember the 26 inch push mower when it came out? Problems. The gravley can stand up to alot, trust me. It can pull out a 52 exmark out of the mud, pull small trees, even cut grass real nice.
