Had a few years to learn now, started running the hiller a little narrower so we don't have as many potatoes roll out the sides. We have sandy soil, so it is a bit more of a problem than if it was a heavier clay soil. Overall, its still working very nicely, can pretty much guarantee it will outlast me.
This digger was probably made for the first tractors with pto. It still does the job. Good harvest!
