MTD 490-110-M155 Mulching Blade

This blade set is designed for 50-inch mower decks and is compatible with select models from Murray, Troy-Bilt, Craftsman, Columbia, and Yard-Machines. Because compatibility can vary by specific model year and series, you should always cross-reference your mower's original equipment part number with the MTD 490-110-M155 specifications in your owner's manual.

While these blades are engineered for mulching, they are designed to replace existing blades on compatible 50-inch decks. If your mower was not originally equipped for mulching, you may need additional components, such as a mulching plug or baffle, to achieve the desired results.

Mulching blades feature a specific curvature and cutting edge designed to lift grass clippings and chop them into fine particles. This process returns vital nutrients to your soil as the clippings decompose, promoting a healthier lawn compared to standard blades that simply discharge clippings.

This product is a blade set designed to accommodate the requirements of a 50-inch mower deck. Please check your mower's deck configuration to ensure you have the correct number of blades for your specific spindle setup.

To maintain a clean cut and efficient mulching performance, inspect your blades for dullness or damage after every 20 to 25 hours of use. If you notice the grass tips are fraying or turning brown, it is time to sharpen the edges or replace the blades entirely.
