Rolling it won't stop erosion. As Mark suggested crusher run may be the ticket or fill the rut with 3/4 crushed stone. No fines or sand in it to wash out.
Von, I have a water tank, angle iron, and welder. Where did you get, and how did you mount the bearings for the axel to turn in?? Colud you take some pics of that part of your roller and post for reference please. been wanting to do this for a couple of years.
Thanx, Bert
