Know before you buy
This blade is designed for 21-inch Toro mower decks. It serves as a direct replacement for part number 108-3762-03, so it will fit any model that originally utilized that specific blade.
The Super Recycler design features specialized geometry optimized for mulching. It is engineered to circulate grass clippings longer under the deck, resulting in a finer cut and better nutrient return to your lawn.
While this blade is specifically optimized for mulching, it can be used for bagging or side-discharging. However, for the best performance in those modes, you may find that a dedicated high-lift blade provides better airflow.
This is a genuine Toro OEM replacement part. It is manufactured to the exact specifications and quality standards required for your Toro mower.
You should generally replace your blade once a year or whenever you notice the cutting edge has become dull or damaged. A sharp blade is essential for a clean cut, which prevents grass tips from turning brown and keeps your lawn healthy.
