Fourtry 586859604 High-Lift Mower Blade for 21-Inch Decks – Husqvarna & Poulan Compatible

Overview

The Fourtry 586859604 high-lift mower blade is crafted as a reliable 21-inch replacement option designed to fit a broad range of Husqvarna and Poulan decks. Built from durable steel, the blade’s high-lift geometry helps lift grass for a cleaner, more even cut, especially when mowing uneven lawns or denser turf.

Compatibility spans a wide set of models. On the Husqvarna side, it works with L221A, L221AHK, L221AK, L321AH, L321AHE, L321AHX, L421P, LC121FH, LC221A, LC221AH, LC221FH, LC221FHE, LC221R, and LC221RH. For Poulan, it covers P160RWD and Poulan Pro PR675AWD. Red Max CWP21 and RWRH21 are also noted as compatible options in the same family of deck sizes. This broad coverage means many 21-inch deck owners can consider this blade as a direct replacement option.

Durability is a focus. The blade is forged from robust steel and shaped with a high-lift profile intended to improve grass lift and cutting efficiency. The edge ships pre-sharpened and is coated with a protective paint layer to aid safe handling during installation; the coating naturally wears away with use, helping the blade stay ready for action while minimizing sharp handling hazards at setup.

What you receive is a single replacement blade tailored for 21-inch decks. Key specifications include a length of 21 inches, a width of 2-1/4 inches, a center hole of 0.97 inches, and a thickness of 4/25 inch. Before purchasing, please verify that your spindle hubs use a 5-point star pattern to ensure a correct fit and avoid incompatibilities. This due-diligence step helps you select a blade that integrates smoothly with your mower’s spindle.
