I rented one before an it worked quite well to move 10 yds of topsoil for a job I did last year. The job I need to use it for now will be to move topsoil from the street up a sloped front yard and into the back yard. The front isn't the problem, it's the back yard. Will it be able to go up a medium grade then turn 90* to the right on the slope and go 40 yards, then be able to dump sideways on the slope? How stable are these sideways on slopes. The slope is easy to walk on and I currently cut it with a walkbehind if that helps. I would say it's a 30*-35* degree incline? I know a pic might help, but lets see what some of the responses are first. I think the Dingo I rented was a 425, it had no platform behind it.
