Husqvarna 586859604 Reaper Blade L221A L421P LC221A LC221AH L321AH LC221RH OEM

What It Is

The Husqvarna 586859604 Reaper Blade is a factory OEM mulching blade designed for select Husqvarna walk-behind mowers. It’s built to chop grass clippings finely and recut them for even dispersal, ideal for lawns where you want to skip bagging.

Fitment & Compatibility

Before buying, confirm your mower’s deck size and model. This blade fits 21-inch Husqvarna decks on these models: L221A, L421P, LC221A, LC221AH, L321AH, and LC221RH. It will not fit other deck sizes (e.g., 20-inch or 22-inch). Check your current blade’s center hole diameter and overall length—this OEM part matches Husqvarna’s original specs exactly. Aftermarket blades may vary in balance or thickness, so stick with OEM for guaranteed fit. Also verify your blade adapter or spindle type; this blade uses a standard 5-point star center hole common on Husqvarna 21-inch decks.

Key Things to Know

• Quality: OEM steel is heat-treated for durability and holds an edge longer than many aftermarket options. Expect consistent balance out of the box.
• Installation: Straightforward—remove the old blade, clean the spindle, and torque the bolt to 35–45 ft-lbs. Use a blade removal tool or block of wood to hold it.
• Common gotcha: Don’t reuse the old washer or bolt if they’re worn. Replace them to prevent loosening during operation.
• Performance: This is a mulching blade, not a standard lift blade. It creates finer clippings but may clog in tall, wet grass—run at full throttle and overlap passes.

Should You Buy It

Buy this if you own one of the listed 21-inch Husqvarna models and want a factory-perfect mulching blade that’s reliable, durable, and easy to install. It’s ideal for homeowners who mow regularly and prioritize clean mulching over bagging. Skip it if you need a standard lift blade for side-discharge or have a different deck size.
