586859604 Mower Blade Compatible with Hus qvarna Pou LAN L421P LC221A LC221AH LC221FH LC221R P160RWD 21 inch Decks, High Lift

What It Is

This is a high-lift replacement blade for select Husqvarna and Poulan Pro 21-inch walk-behind mowers. It’s designed to provide stronger suction for better grass clipping discharge and bagging performance, especially in thick or damp grass.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 21 inches (measure diagonally from blade tip to blade tip). This blade fits models including Husqvarna LC221A, LC221AH, LC221FH, LC221R, P160RWD, and Poulan Pro P160RWD. It’s an aftermarket replacement for OEM part number 586859604. Check your blade’s center hole diameter (should be 7/8-inch) and overall length (21 inches). If your mower uses a different center hole size or offset, this won’t fit.

Key Things to Know

• High-lift design improves bagging and side discharge but increases engine load—may bog on underpowered mowers or in very tall grass.
• Installation is straightforward with a socket wrench and blade removal tool (or wood block to lock blade). Torque to 35-50 ft-lbs.
• Balance check recommended after installation—an unbalanced blade causes vibration and bearing wear. Use a blade balancer or a nail in a wall.
• Quality is solid for the price—thick steel holds an edge well, but some users report minor paint chipping on first use (cosmetic only).

Should You Buy It

If you own a compatible Husqvarna or Poulan Pro 21-inch mower and want better bagging or discharge performance without paying OEM prices, this blade is a good value. Avoid it if your mower has a smaller engine (under 140cc) or you primarily mulch—a standard or low-lift blade would be better. For the price, it’s a reliable upgrade for most homeowners.
