DESCRIPTION The Oregon® Gator® G6™ 392-057 lawn mower 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. DETAILS Center hole: 15/16" 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.
