Is your Cub Cadet mower not cutting as cleanly or leaving behind clumps of grass? It might be time for a new blade. This is the genuine OEM Cub Cadet replacement mulching blade, part number 942-0741A. It fits a ton of their walk-behind models: think SC100, SC300, SC500, SC700, SC621, and many others (check the full list in the description to be sure for your specific mower). It also replaces older part numbers like 942-0741 and 942-04276. Mulching blades are designed with special curves and lifts to cut grass finely and recirculate clippings back into the lawn as fertilizer. Always disconnect the spark plug before changing the blade! You'll need a socket wrench and maybe a block of wood to keep the blade from turning. Swap it out every season or so for a healthier, better-looking lawn. Keep your mower performing like new with the right factory part.
