What It Is

This is a 22-inch mulching blade set (1 pack) designed for select Husqvarna walk-behind mowers. It replaces OEM part numbers 580244001 and 580244002, and is intended to chop clippings finely for nutrient recycling, not side-discharge or bagging.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: This blade is exactly 22 inches long (center hole to tip). Measure your mower deck’s cutting path—most Husqvarna 22-inch decks use a 22-inch blade, but some models with a 22-inch deck may use a 21.5-inch blade. Measure your old blade or deck width.
• Model list: Fits Husqvarna HU500F, HU550FH, HU675FE, HU700F, HU700L, HU725AWD, HU725F, HU800AWD, LC 356AWD, LC 356V, HU 700L, LB 155S. Cross-check your exact model number (stamped under seat or on frame).
• OEM vs aftermarket: This is an aftermarket blade, not genuine Husqvarna. The center hole and oval pattern may differ slightly from OEM. If your mower uses a star-shaped or odd-center hole, this won’t fit.

Key Things to Know

• Installation difficulty: Easy—requires a socket wrench and torque to ~40-50 ft-lbs. Use a blade removal tool or block the blade to prevent spinning.
• Quality concerns: 3.7/5 rating with only 8 reviews. Some users report balance issues out of the box—check blade balance before installing (hang on a nail or use a balancer).
• Mulching performance: Works well on dry, short grass. For tall or wet grass, clumping is common; slow your ground speed or make two passes.
• Durability: Steel thickness is adequate for residential use but not commercial abuse. Expect to sharpen or replace every 1-2 seasons depending on lawn size.

Should You Buy It

Buy this if you need a budget-friendly 22-inch mulching blade for a listed Husqvarna model and you’re comfortable checking balance and fitment yourself. Skip it if you want OEM reliability, a zero-balance guarantee, or need a blade for a non-listed model (e.g., Husqvarna riding mowers or different deck sizes). For $21, it’s a decent value for light residential use, but don’t expect premium longevity.
