The Husqvarna 46-Inch Mulch Kit easily attaches to your lawn tractor deck to help lessen or eliminate the need to rake after mowing your lawn. This kit consists of one mulch plate, two mulching blades and mounting hardware to make turning your lawn mower into a mulching mower easy. The mulch plate blocks grass from escaping from under the mower deck, leaving lawns looking pristine. Mulching is a natural way to fertilize and return nutrients to your lawn with the tiny clippings produced. This mulch kit fits riding lawn mowers and zero-turn mowers with two 46-inch blade decks. All Husqvarna tractors are equipped with premium high-lift bagging/discharge blades. Husqvarna lawn mower blades are forged with hardened steel and designed to maximize cut quality while boosting overall performance. With a high-lift, powerful suction and a clean discharge for bagging or mulching, this mulching blade set delivers excellent 4-in-1 performance. You can easily install the kit onto your lawn care equipment with the included matching mounting hardware that ensures a secure fit. This mulch kit is a genuine original manufacturer part and is required to convert tractors to mulching units.
