This Toro OEM 18-inch mulching replacement blade features more pronounced curves and a longer cutting edge compared to standard discharge blades, enabling it to cut grass and immediately redirect clippings back into the deck for additional passes. The result is finely shredded clippings that settle into the lawn quickly and decompose into nutrients, reducing the need to bag or dispose of grass waste. Compatible with multiple Toro riding lawn mowers models — verify your model and serial number before ordering.
