Know before you buy
These blades are designed as a direct replacement for Ferris OEM part number 5101756s. Please verify your specific mower model's manual to ensure this part number matches your requirements.
This 3-pack is specifically engineered for mowers equipped with a 52-inch cutting deck. Using the correct blade length is essential for maintaining proper deck balance and cut quality.
Standard lift blades are designed for general-purpose mowing. They provide enough suction to lift grass blades for a clean cut and effectively discharge clippings, making them a versatile choice for most standard lawn conditions.
While these are manufactured to replace Ferris 5101756s, they may fit other brands if the specifications match. You must confirm that your mower requires an 18-inch blade with a 5/8-inch center hole and a 2.5-inch width before installing.
Replacing all three blades simultaneously ensures that your mower deck remains balanced and provides an even cut across the entire width of the deck. Mixing old and new blades can cause vibration and uneven grass height.
