Genuine Husqvarna 22" Reaper Blade in Black for Walk Behind Mowers HU725AWD, HU800AWDX / 587799402, 587799401

What It Is

This is a genuine Husqvarna 22-inch reaper blade designed for heavy-duty mulching and bagging on select Husqvarna walk-behind mowers. It’s built for residential and commercial use, offering a curved design to lift grass for a cleaner cut.

Fitment & Compatibility

Before buying, confirm your mower model: this blade fits Husqvarna HU725AWD and HU800AWDX (both AWD models). The OEM part numbers are 587799402 and 587799401. Measure your existing blade length—must be exactly 22 inches from tip to tip. Check the center hole diameter (typically 1 inch) and the oval drive hole pattern. This blade is not compatible with standard 21-inch decks or most other brands. If your mower uses a different blade design (e.g., straight or low-lift), this won’t work. Always verify your deck’s blade spindle type; some AWD models require a specific offset.

Key Things to Buy

• Quality: Genuine Husqvarna steel, pre-sharpened, and heat-treated for durability. Expect longer life than generic blades, but inspect for warping after heavy use.
• Installation: Moderate difficulty—requires a socket wrench and blade removal tool. Use thread-locker on the bolt and torque to factory specs (typically 40-50 ft-lbs). Sharp edges; wear gloves.
• Gotchas: The “reaper” design is aggressive for tall grass but may leave strips in dry conditions. Not for fine fescue or manicured lawns. Check blade balance after installation; unbalanced blades cause vibration and damage spindles.
• Common issues: Some users report the blade arriving with minor coating chips—cosmetic only, but inspect for deep nicks. Always replace in sets (both blades) for even wear.

Should You Buy It

If you own a Husqvarna HU725AWD or HU800AWDX and need a genuine, heavy-duty blade for mulching thick or wet grass, this is a solid choice. Skip it if you have a different model, want a standard lift blade, or are on a tight budget—aftermarket options exist for half the price.
