I went to a local ferris dealer today and I was looking at the Ferris Evolution. It seems pretty nice, but the seating position feels like it would all go right to your knees, can someone who has one confirm this? Hows it on hills? Just looking at it you would think it would just tip right over. I was also slightly interested in the Ferris is500z. I mean it seems nice, but the only options are briggs and stratton "professional series" engines. I know briggs isn't really what it used to be, but are these engines any better? Anyways, I've got some time until I get a new mower, because I plan on getting one next spring. Any input would be appreciated.
