I currently have a 36 in Snapper walk behind 14 HP Kaw. I'm wanting to upgrade this year and maybe go full time. I'm wondering what a 48in or 52in gear drive Exmark walk behind is costing (roughly) as opposed to hydro drive. I think the 19 HP Kaw is the biggest they have which is what I'm interested in. Anyone have an idea-feedback is greatly appreciated! Thank you for all the info on this site!
