I had another look at this one yesterday and I am convinced I am going to have to put a lazy axle on it at the rear so it can be tilted back to allow the drive wheels to just clear the ground. You can pull it backwards but it is not easy, the drag ( I'm not sure what is causing the drag) is hard to pull against. Pushing forward is no harder that pushing a normal mower. When engaged the drive works fine although a bit too fast for me to keep up.
