Husqvarna OEM LC221A, LC221RH Blade 21" Reaper W/O Notches

What It Is

This is an OEM 21-inch “Reaper” blade from Husqvarna, designed for the LC221A and LC221RH walk-behind mowers. It’s a high-lift, non-notched blade intended for tough, thick, or wet grass where superior suction and mulching are needed.

Fitment & Compatibility

• Deck size: Fits only 21-inch cutting decks. Measure your blade length from tip to tip—must be exactly 21 inches.
• Model check: Direct fit for Husqvarna LC221A and LC221RH. Also compatible with some Husqvarna LC221 series variants—verify your model number on the mower’s ID tag.
• OEM vs aftermarket: This is genuine Husqvarna part 583752901. Aftermarket blades may fit but often differ in thickness, balance, or steel quality. OEM ensures exact fit and performance.
• Mounting hole: Center hole is 7/8-inch diameter with a 5-point star pattern. Check your blade adapter before buying—if your mower uses a different pattern, this won’t mount.
• Notches: This blade has no notches. If your current blade has notches (for anti-scalp wheels or special deck shapes), this will not work.

Key Things to Know

• Installation difficulty: Easy—requires a socket or wrench to remove the center bolt. Torque to 30-40 ft-lbs. No special tools needed.
• Common gotcha: The high-lift design creates strong airflow, which can blow debris sideways. Use a grass catcher or bag for best results; side-discharge may scatter clippings.
• Durability: Heat-treated steel holds an edge longer than standard blades. Expect 2-3 seasons of use before significant dulling, depending on yard conditions.
• Balance: OEM blades are factory-balanced. Still, check balance after sharpening or if you hit a rock. An unbalanced blade vibrates and can damage the spindle.

Should You Buy It

This blade is right for you if you own a Husqvarna LC221A or LC221RH and need maximum cutting power in dense, wet, or tall grass. It’s a direct OEM replacement with proven reliability and high user satisfaction. Avoid if your mower uses notched blades or if you prefer a low-lift, mulching-only design—this one is aggressive and best with a bagger.
