You can count on the Oregon® 492-731 replacement lawn mower blade to be the best in the industry. Our 26 quality standards ensure that you’re buying a sharp, high-performance blade that mounts properly. It delivers a clean cut for quality results.
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.
