Lawn Mower Blades what is the correct size
Let say you have a 48” deck and 3 blades one would say 48” divided by 3 we would need three 16” lawn mower. Well that is no always the case if the blades are in a straight line then maybe that would work but if the center blade is in front of the other 2 mower blades then the blades could be longer.
When buying lawn mower blades it is best to have the oem part number to search for the blades needed, but if you don’t then you will need to measure each blade diagonally from cutting edge to cutting edge and measure the center hole, some have a star for the center hole you will need to count how many point it could be 5, 6, 7 or 8.
