I bought mine used from an older guy for $30. I had seen it sitting beside an old wood shed for several months so I decided to stop in and see if he wanted to sell it. I used 5 old steel plates to add weight and a piece of pipe to hold them in place. It will not cut through thick grass but if you mow it down to near bare dirt it does really well. It took me about 3 hours to get it ready and I' ve only got about $60 total in it. Here' s a picture of it.

Here' s a picture of my new food plot after discing it.
