Ranwin 3-Pack Heavy-Duty Mower Blades for Grasshopper 61-inch Duramax Decks – Replacement Notched High-Lift Blades

Product overview

Upgrade your mowing routine with Ranwin 3-pack heavy-duty mower blades, designed to fit Grasshopper 61-inch Duramax decks. This triple blade set offers a confident, controlled cutting experience, with a notched high-lift profile that helps lift turf and channel clippings for a cleaner finish. The result can be a more efficient cut across larger lawn areas without excessive re-trimming.

Each blade in this pack is built for durability and balanced performance. With a length of 20-9/10 inches, a width of 2-1/2 inches, a center hole diameter of 1/2 inch, and a thickness of 1/5 inch, the set combines sturdy construction with precise cutting geometry. The trio approach can cover more ground per pass, potentially shortening mowing time while maintaining steady edge quality.
