• Center hole: 15/16"
• Requires 3 blades for 50" cut
• High-lift: The aggressive blade angle increases air flow to push debris up-and-out for superior bagging or side discharge.
• Superior mulching for bagging and discharge efficiency
• Enhanced hardening to keep the blade sharper and more durable
• Made to exact OEM specifications
• Tungsten carbide is “fused” into the blade – creating an ultra-hard layer at the cutting edge and increasing the time between sharpening.
