We bought a bew Ferris 1500 this yr and have not been happy. Now we are thinking about swithching to 2 w/b's instead of 1 z and 1 w/b. We have had a few customers complain about the z and the quality of cut is just not there. So we are wondering if 2 hydro walks would be better. I like the Exmarks and that is what I'm leaning towards. We do residentials although we want to get into small commercial props so do we really need a fast z? What do you think? What kind of prices are the Exmark hydro w/b's?
