after using gear drive wb's and ZTR's for years, I finally purchased a hydro WB for this season. I needed something to lay down a good stripe, yet, lighter in weight than a ZTR and faster than a gear drive. I selected a Gravely Pro H, Pro-steer. Things were a bit tough for the first few weeks, but I have finally mastered the controls. This thing has a 17 hp Kaw and a 52" deck. It pulls me around on a sulky (when needed) without hesitation. Keep in mind...I weigh 260. I'm very happy with the hydro route I have taken and watch my two remaining gear drives sit idle.
