While it is a champion for standard side-discharging and bagging, its design is not optimized for fine mulching, where it may leave larger clippings compared to specialized blades.

When compared to the specialized Briggs & Stratton 22″ Mower Blade Wave Steel Deck, this 40″ blade is built for coverage and a pristine finish rather than mulching.

The unique “Wave” geometry is engineered to solve the problem of grass clippings by turning them into a fine, nutrient-rich mulch that feeds your lawn.

The performance of this 22″ Mower Blade is most impressive in its mulching mode, where the aerodynamic shape creates a powerful updraft to recut clippings multiple times. This process results in incredibly fine particles that decompose quickly, leaving a clean and healthy lawn.

While the OEM version guarantees a factory-spec finish, the LikeLion blade is for the user who demands maximum wear resistance and wants to reduce long-term maintenance.

This makes it exceptionally effective for bagging, creating powerful suction that packs clippings tightly and reduces the frequency of stops. It is not, however, designed for mulching, and using it for that purpose will result in clumping and an untidy lawn.
