Product Details

  • Center hole: bow-tie
  • Tungsten carbide is “fused” into the blade – creating an ultra-hard layer at the cutting edge and increasing the time between sharpening.
  • X-Tended Cutting Length™ optimizes the cutting efficiency with each revolution.
  • Gator Mulcher® provides cleaner, more efficient cutting performance that can eliminate the need to bag, saving time and hassle.
  • High-lift: The aggressive blade angle increases air flow to push debris up-and-out for superior bagging or side discharge.
  • Replaces major brand: Craftsman
