532180054 High Lift Blades for 48" Deck, 180054 Mower Blades Compatible with Hus-qvarna YTH24V48 YTH2348, Pou LAN PP22V48, Craftsman, AYP, Replaces 173920 173921 539107519, 3 Pack

What It Is

This is a set of three high-lift lawn mower blades designed for 48-inch cutting decks. They increase airflow under the deck for superior grass clipping discharge and bagging performance, ideal for tall or thick grass in residential mowing.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 48 inches wide (measured blade tip to blade tip). These blades fit specific Husqvarna (YTH24V48, YTH2348), Poulan (PP22V48), Craftsman, and AYP models with a 48-inch deck. They replace OEM numbers 173920, 173921, and 539107519. Measure your existing blade length (should be roughly 20.5 inches), center hole diameter (usually 1 inch), and the distance from center hole to outer mounting holes. Ensure your spindle offset matches the blade’s design (flat or dished). If your mower uses a different spindle pattern or blade length, these won’t fit.

Key Things to Know

• High-lift design improves bagging and discharge but increases engine load and can cause more wear on belts and spindles, especially in wet or heavy grass.
• Installation difficulty is moderate; you’ll need a socket wrench and a blade removal tool (or block of wood). Always disconnect the spark plug and wear heavy gloves.
• Common gotcha: these blades may not fit decks with low clearance or older spindle assemblies. Check for any deck obstructions before mounting.
• Aftermarket quality is solid at this price, but inspect for balance after installation—unbalanced blades cause vibration and poor cut.

Should You Buy It

Buy these if you have a compatible 48-inch Husqvarna, Poulan, Craftsman, or AYP mower and need reliable, high-lift blades for bagging or discharging thick grass. They’re a cost-effective alternative to OEM parts with strong user satisfaction. Avoid if your deck is smaller, your spindle pattern is different, or you prefer mulching blades.
