I've got a 54" Exmark from 2004, bought used in 2010. I've beat the living snot out of it and it keeps on ticking. New blades each spring, have replaced a couple of spindles due to my roughness with it and thats about it. Most of the commercial guys around here run Exmark. Have a friend that cuts commercially, he has 3 Deere's, but he grew up on a dirt farm in Minnesota and his blood runs green already.
