Time to replace those worn-out mower blades? This 2-pack of mulching blades fits a ton of 42-inch riding mower decks – Craftsman, Husqvarna, Poulan, AYP, and Ariens models. They’re heavy-duty, made of tough iron, and designed to mulch grass finely so it decomposes back into the lawn. Great for tall grass and weeds. Each blade is 20-7/8” long with a 5-point star center hole. Just make sure your mower deck is 42 inches and matches the part numbers listed (like Ariens 21546095, Craftsman 134149, etc.). Mulching blades like these cut clippings into tiny pieces, so you don’t have to bag as often. They’re not the best for super wet grass (can get cloggy), but for normal conditions, they work great. Easy to install with basic tools. Keep your lawn looking neat and healthy without all the cleanup. A must-have for spring and summer mowing.
