Finding the Right Lawn Mower Blade for Your Mower
When it comes to lawn mower blades, you might assume that they are all pretty much the same. However, did you know that the center hole on lawn mower blades is actually proprietary and trademarked by each manufacturer? This means that each manufacturer has a different design for the center hole on their blades, and they are not interchangeable with blades from other manufacturers.
Aftermarket manufacturers of lawn mower blades cannot use the shape that is used on the OEM part. Therefore, they have to create their own design that works with the OEM blade spindle.
AYP / Craftsman / Sears / Husqvarna / John Deere typically uses a five-pointed star shape for their blade center hole.
MTD / Troy Bilt / Toro / Cub Cadet / Yard Machines uses a six-pointed star shape for their blade center hole for riding mower blades and often use a “bow-tie” shape center hole for their push mower blades.
