Center Bore: 7/8″ Tungsten carbide is “fused” into the blade, creating a super-hard layer on the cutting edge and increasing the time between sharpenings. The extra width and thickness extend the life of the blade and allow for a larger arc of lift for improved bagging and mulching. The 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 turn.
