Great little machine. Tilled an area of about 2000 square feet. (half of which was never tilled before) This tiller plowed through like a champ, dug up hundreds of fist sized rocks and a couple the size of my head. A little bouncing and hesitation on the big ones but hardly noticed the little ones till I tripped over them. This thing also shredded numerous tree and shrub roots with little or no hesitation. (mostly dead and rotting but some the size of my wrist) I was a little worried the wheels would be to flimsy but, they are only needed to move from shed to work area so really not an issue. Some reviewers complained about the spike holder but mine held up just fine. Other reviewers complained that the hand controls should be reversed. I would disagree, its easier to hold them down with the natural weight of arms and hands while working rather than relying on just hand strength to squeeze controls. Only had this thing for a season and a half but I am extremely happy with it.
