Please note this item does not come with the bag frame. It includes only the soft part of a complete bag. It is for this reason that I can offer such a low price for the item. If you also need the bag frame, please buy separately ?????? This product does not include grass catcher frame. Grass collection bag replace 115-4664. Collects grass blown from beneath the deck, making your mowing work easy
