Large lawn roller. 24" x 18" diameter Used for rolling seed into soil, or for flattening freshly distributed soil. I used it empty twice and it worked great, but water or sand can be added for additional weight. I used it manually by rolling it around with the handle, but a person could also pull it with a riding lawnmower if they had one. These are $230 plus taxes new. Asking $110 obo.
