The Murray M24759558 mulching kit is an original equipment manufacturer (OEM) accessory designed to convert 46-inch cutting decks on Murray lawn tractors for mulching operations. This kit includes mulching blades and baffles that recirculate grass clippings beneath the deck, finely shredding them before they are returned to the lawn as natural fertilizer. It helps maintain a healthier, greener lawn by reducing the need for bagging and improving nutrient absorption. Ensure compatibility with your specific 46-inch Murray lawn tractor model.
