This OEM part is a mulcher mower blade for lawnmowers. The mulcher mower blade is the blade assembly that is used to cut grass in a lawnmower. Over time, the mower blade can deteriorate, becoming dull and ineffective with extended use. If it's been a while since the blade has been replaced, it might be time for a new one. Luckily replacing a mower blade is a relatively simple process. Before beginning, the engine cool and wear work gloves. Disconnect the spark plug wire from the spark plug and remove the fuel tank cap. Place a plastic bag over the fuel tank opening and reinstall the fuel tank cap to keep gasoline from leaking out of the fuel tank cap vent. Tilt the mower back to lift the front wheels and secure the mower handle to a work table to hold the motor steady. Wedge a block of wood between the mower blade and the deck to keep the blade from turning when loosening the blade bolt. Loosen and unthread the blade bolt while holding the cutting blade to keep it from falling. Pull the blade, blade support, and blade bolt off the crankshaft. Make sure to position the new parts on the crankshaft. Hand-tighten the new blade and bolt onto the crankshaft. Use a torque wrench to tighten the blade bolt. This genuine replacement part is compatible with MTD brand lawnmowers.
