8TEN LawnRAZOR Blade for Husqvarna Poulan L421P LC221A LC221AH LC221FH LC221R P160RWD 21" 586859604 (High Lift)

What It Is

The 8TEN LawnRAZOR High Lift Blade is a sharp, durable replacement blade designed for 21-inch walk-behind mowers from Husqvarna and Poulan Pro models, including the L421P, LC221A, LC221AH, LC221FH, LC221R, and P160RWD. Its high-lift design increases airflow for superior bagging performance in heavy grass or leaf cleanup.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 21 inches (center hole to blade tip). This blade replaces OEM part 586859604 and fits Husqvarna/Poulan models listed above—check your model number on the mower’s sticker or owner’s manual. The blade has a 1-inch center hole and 5-point star drive (not universal). Measure your existing blade’s length (21") and center hole shape. Aftermarket, but meets OEM specs.

Key Things to Know

• Quality: Made from heat-treated steel with a coated edge; holds sharpness well but may dull faster than OEM in sandy soil.
• Installation: Easy swap with a socket wrench—use a blade removal tool or block the blade to prevent spinning. Torque bolts to 30-40 ft-lbs.
• Common Gotcha: High-lift blades increase engine load and may cause vibration if not balanced—always balance after install. Not for mulching or side-discharge decks without a high-lift kit.
• Price/Value: At $21.95, it’s cheaper than OEM ($30+) with excellent reviews (4.8/5 stars from 69 ratings).

Should You Buy It

Buy this blade if you own a compatible Husqvarna or Poulan 21-inch mower and need reliable bagging performance in thick grass or leaves. It’s a cost-effective, high-quality upgrade over worn OEM blades, but skip it if you primarily mulch or have a sandy yard that accelerates dulling.
