That would be great if you keep all your roads flat w/o any crown on them for drainage.
Actually they are all flat. Our main driveway to the house is about 500' and is concrete. These "roads" I am talking about maintaining are in the fields, turn rows , etc. They are just dirt and don't get driven on very often. Not that it rains much here but if it is too wet we don't have a need to travel on them. They get minor ruts from time to time from various things like atvs, etc but just making them flat again is fine. I know a proper road has a crown but these are not that important. I do like to keep me gravel parking area flat though.
