Looks like a pretty good design for a normal sized yard. Packaging could use some work though. I didn’t get I wheel bolt (1/2 x 4) and a spike bushing. Both were available locally. Instructions seemed a bit vague since I blame them for having to stack the spikes on the axle wrong. In retrospect, the important washer was in the photo. I’m just not used to lining parts up by photo. If they had said “the think one”
