For those of you considering purchasing MowDeck to keep their decks free of grass, you may want to reconsider. After several people on this site raved about it, I bought a case, have scraped and sprayed my decks several times, and I am very disappointed at the results. The grass I've cut has been wet (little dry weather around here all spring) and maybe I'm expecting too much. But a week after I spray MowDeck under my decks, I have to scrape about twenty pounds of compacted clippings from each deck. Not what I had expected.
