Blade Tri-Cut
Genuine Mtd part
By: Mtd
Part Number: 781-0748-0637

The tri-cut blade works to replace edger blades to ensure they are sharp and capable of cutting through the grass and turf properly. The blade is made from metal and can provide users with clean edging around the edges of their lawn and around flower beds. Regularly examine the edger blade regularly to ensure that it is not bent, broken, or otherwise damaged. If your current edger blade is no longer sharp and cannot be sharpened, it is time for a replacement. Without a sharp blade for the edger, it will be impossible to take care of the lawn properly. To replace the blade in your edger, the only tool required is a wrench. Replacing the blade is easy, and it should not take more than 15 minutes. This OEM part is sold individually, and it works with edgers from a range of brands, including Craftsman, Yard Machines, MTD, Troy-Bilt, Bolens, and Yard-Man.
