I am going to buy a rake to turn some hay with and someone has a JD Wheel rake that I looked at. The only thing that turns the wheels is them dragging on the ground as you pull it. I thought it would at least be a ground driven rake with a gear box or something other than the tines dragging in the dirt!! I can't see how this thing would turn a windrow of alfalfa or any heavy hay. Are all of the wheel rakes made this way? My pasture is level with a slight role but not on any side hill. Maybe I should try and find a pto driven side delivery, even if it will cost a lot more. Anyone got a better idea? thanks...Phil
