Great machine, although I had already cleared a patch and spread manure by hand, I ran it over the same bit. It burrowed in and going forwards it dug deeper than my hand efforts, end of the row no struggling to turn it, reverse lever and it climbs back out ready to spin around and come back up the row chunking away at 30" at a time. 20 minutes rotovating the 4 hours I took by hand. Only one setback, the door to my shed was not wide enough but a little hinged flap soon cured that.
