Anyone using ferris walk-behinds? I am thinking about just running a crew with walk-behinds to go out and do smaller property's with and have another crew for the Z's to out with. The model I am interested in is the DD 48in, anyone use this one? Any good reviews on it? Any bad ones? One thing that I like about this mower over Ex-mark, scag is the twist of handle to raise the deck just like my 34in simplicity. I havn't seen many ferris's around here, mostly I see is bob cat and ex-mark.
