I bought the mulch kits new when I bought the tractors. I have since got contracts that require bagging, so i will have to buy a bagger. This is the real kit and is complete, including the chute block off plate. I believe there are 4 (or 6??) peices in total. They bolt directly under the deck, creating circles around each blade. They work great, the grass turns into dust...fast. Paid $350 each, looking for $250 Each (usd) Easily shippable.
