Product Details Tungsten carbide is fused into the blade, creating a super-hard layer on the cutting edge and increasing the time between sharpenings. Extra width and thickness extend blade life and allow for a larger arc of lift for improved bagging and mulching. Aggressive blade angle increases airflow to push debris up and out for superior bagging or side discharge. The Gator Mulcher delivers a cleaner, more efficient cut and can eliminate the need for bagging, saving time and hassle. X-Tended Cutting Length optimizes cutting efficiency with every revolution.
