The Oregon® Gator® G6T 396-769 blade is enhanced with carbide. This heavy duty blade is designed for commercial applications and built to withstand rough conditions with top performance and longevity. Tungsten carbide is “fused” into the blade – creating an ultra-hard layer at the cutting edge and increasing the time between sharpening. Greater width and thickness extends blade life and allows for longer lifting arch to improve bagging and mulching. The aggressive blade angle increases air flow to push debris up-and-out for superior bagging or side discharge. Gator Mulcher® provides cleaner, more efficient cutting performance can eliminate the need to bag, saving time and hassle. X-Tended Cutting LengthT optimizes the cutting efficiency with each revolution. Replacement for major brand: John Deere. Fits the Following Models. Replaces the Following Blades.
