586859604 586859602 Mower Blade, Compatible with 21" Deck Hu sqvarna Pou LAN L421P LC221A LC221AH LC221FH LC221R 21 Inch Deck, Replace 501082501 High Lift Blade

What It Is

This is a high-lift replacement blade designed for 21-inch deck walk-behind mowers. High-lift blades create a stronger vacuum for improved grass lifting and mulching, making them ideal for thicker lawns or side-discharge use.

Fitment & Compatibility

Check these before buying:

• Deck size: Only fits 21-inch decks. Measure your blade length—must be exactly 21 inches from tip to tip.
• Models: Compatible with Husqvarna L421P, LC221A, LC221AH, LC221FH, LC221R, and select Poulan/LAWN models. Also replaces OEM part 501082501.
• Center hole & offset: Verify your mower uses a standard 5-point star center hole and the blade’s offset matches your deck’s spindle shape. High-lift blades may have a different lift curve than standard blades.
• OEM vs aftermarket: This is an aftermarket blade, not OEM. Check that the thickness (typically 0.175–0.200 inch) matches your original.

Key Things to Know

• Quality: 4.8 stars from 9 reviews suggests good build, but limited feedback—inspect for balance and sharpness on arrival.
• Installation: Straightforward if you’re comfortable with a socket wrench. Use a blade removal tool or block the blade to prevent spinning. Torque to manufacturer spec (usually 40–50 ft-lbs).
• Gotcha: High-lift blades increase engine load and may reduce runtime on battery mowers. Also, they can create more noise and vibration if the blade is unbalanced.
• Common issue: Aftermarket blades sometimes have slightly different hole alignment or thickness; check fit before tightening fully.

Should You Buy It

Buy this if you need a cost-effective high-lift blade for a 21-inch Husqvarna or compatible mower and prefer a budget alternative to OEM. Skip if you require exact OEM specs, run a battery mower (where high-lift may drain power faster), or want a blade for mulching only—standard or low-lift blades work better for that.
