These three 18-7\/8\" medium-lift blades mirror the original mounting hole and dimensions for a tidy installation on many John Deere 54\" decks. They’re heat-treated steel with the thickness and center hole size meant to align with common tractor models, so you can swap them in without modifying the deck.\u003c\/p\u003e\n\n\u003ch3\u003eWill these blades fit my John Deere model?\u003c\/h3\u003e\n\u003cp\u003eCheck the part numbers and deck size first: these blades replace John Deere M143520 and UC22010 and are intended for 54-inch cutting decks.
