8TEN LawnRAZOR Blade for Husqvarna Jonsered Poulan HU700F HU550FH HU675AWD 7022RLS Walk Behind 532420463 (High Lift)

What It Is

The 8TEN LawnRAZOR blade is a high-lift replacement blade designed for walk-behind mowers from Husqvarna, Jonsered, and Poulan. It improves grass clipping discharge and bagging performance, ideal for thick or wet grass where standard blades struggle.

Fitment & Compatibility

This blade replaces OEM part number 532420463 and fits specific models including Husqvarna HU700F, HU550FH, HU675AWD, and Poulan 7022RLS. Before buying, measure your existing blade: it must be 21 inches long, with a 1-inch center hole and 0.5-inch offset hole pattern. Confirm your mower deck size is 21 inches and that your model is listed on the 8TEN compatibility chart. This is an aftermarket blade, not OEM, so check that the blade adapter on your mower matches the hole pattern—some older models may require a different center hole size.

Key Things to Know

• High lift design: Creates strong airflow for better bagging but increases engine load and may reduce run time on battery mowers.
• Installation difficulty: Easy with basic tools (socket wrench, torque wrench). Always torque to 30–35 ft-lbs and recheck after first use.
• Gotcha: The blade is sharp and thin—wear gloves. Some users report minor balancing issues; use a blade balancer before mounting.
• Not for mulching: This is a discharge/bagging blade. If you want mulching, look for a different 8TEN or OEM blade.

Should You Buy It

If you own a compatible Husqvarna, Jonsered, or Poulan walk-behind and need a reliable, affordable high-lift blade for better bagging in tall or damp grass, this is a solid buy. It’s not for mulching or low-lift applications, but for its price and performance, it’s a practical choice over OEM.
