These notched high-lift blades are engineered to pair with the 5-star mounting pattern, delivering a balanced feel and consistent blade engagement to support smooth, even cuts across varied lawn conditions.

Installation notes and care

Important installation details help you prepare quickly. You do not need to remove the blade’s protective paint before use; the coating helps protect your hands during handling and rust resistance. Expect the paint to wear off after several minutes of mowing as part of normal use. Before purchasing, confirm that the replacement number, model, and size match your mower to ensure proper fit.

They are designed to align with a 5-star mounting pattern and a 23-inch blade length, which may contribute to a balanced mowing experience when paired with compatible equipment.
