Lonnie,
2Tall is correct. I think the smallest deck they offer DD in is 48", but I could be mistaken. If you can swing it, DD is the way to go. Much more control, easier on the hands, and it virtually eliminates turf marks. They run great on hills too. OK, OK I'll stop rambling.....I have to say nice things or my Ferris sponsorship could be in jeopardy......LOL
Seriously, I have yet to find a w/b that cuts as good as a Ferris. The only thing that comes close is Exmark....close, but no cigar!
P.S. I think they tout the new Hydrocut as a dual hydro, but it is only a single.
