Please note that the blade's edges are very sharp, so do not touch the blade with bare hands. We recommend wearing heavy-duty gloves or wrap the blade with a rag for safe handling. Also, make note when removing the blade how hardware was originally installed. To remove the blade from the mower, wedge a piece of wood between the deck and the blade to keep the blade from moving. Then, use a 3/4" wrench or socket to loosen the blade nut by turning it counterclockwise.
