Was all JD 4020's the same or was there different styles thru the years cause the one we have i hate that thing to me its not user friendly one bit all the controls are mounted on the dash if you want to call it a dash, i like the pto and lift levers to be mounted next to the seat on opposites sides, to me it may be fine if your in a wide open big field but for brushhogging in small areas and box blading it is a pain.
