Part# 21K2Y-G

This product is only available through retailers or servicing dealers.

This 20-7/8" Oregon® Gator® G3™ mulching blade was designed as a replacement for Toro, Lawn-Boy, and Exmark lawn mowers, OEM part numbers 133-8182-03, 133-8183-03, 108-0954, 108-0954-S, 108-0954-03. Made from premium steel and using our patented tooth-twist and high-lift design, the blade recirculates cut grass under the mower’s deck, chopping it up into finer and finer clippings that provide a natural fertilizer for your lawn while lessening the amount of time needed for raking and bagging. The cutting edge comes pre-sharpened at an optimal angle for clean and consistent cuts that will help keep your yard looking green and healthy. Backed by a legacy of craftsmanship that began in 1947, Oregon products undergo a rigorous 26‑point certification process to ensure their safety, quality, durability, and performance.
