GardTok 20-Inch Replacement Lawn Mower Blade for Ryobi 40V – Mulching, High-Hardness Steel

Overview

Meet the GardTok 20-Inch Replacement Lawn Mower Blade, designed to upgrade Ryobi 40V brushless mowers. This blade is a direct replacement for AC04020 and fits a range of Ryobi models, including RY40180/RY40190/RY401110/RY401120 and RY40LM30/RY40LM03. With compatibility in mind, it offers a reliable option to refresh your mower’s cutting edge and restore mowing efficiency.

Built to withstand regular use, the blade uses high-hardness steel and a premium powder-coat finish. The combination helps resist rust and wear, supporting a longer service life while maintaining a sharp, consistent cut across seasons and weather conditions.

Precise, secure installation

The design features a reinforced center hole with a half-moon and round mounting interface to ensure a secure, no-slip seat. Precision-cut mounting holes reduce bowing or misalignment with the mower's plastic bracket, helping you install with confidence and minimal fiddling.

Note: the blade ships unsharpened, allowing you to tailor the edge to your grass type and preferred sharpness. This approach supports a safer transit and a customized mowing experience from the first use.

Performance that matters in the yard

The blade’s high-lift design and extended cutting surface are built to maximize mowing efficiency. It mulches grass into finer clippings that settle into the lawn and can contribute to a healthier appearance over time. The result is a tidy, uniform cut with less residue left on the turf.
