I bought this tow behind plug aerator, so I could over seed my lawn, I put four cement blocks on it and towed it around the yard, it exceeded my expectations and I’m quite happy with the results, the kind of thing you ask yourself why didn’t I get one sooner, the unit appears to be very well made, I did change the front coupler, I have a three point hitch on my lawn tractor so I put a coupler for a regular trailer hitch, it works perfectly, and seems quite sturdy.
