532180054 173920 High Lift Mower Blades Compatible with 48" Deck Hus-qvarna YTH24V48 YTH2348 Pou-LAN PP22V48 Lawn Tractor, Replace 180054 539107519 532173920 539107519 PP24005, 3 Pack

What It Is

This is a 3-pack of high-lift mower blades designed for 48-inch cutting decks used on Husqvarna YTH24V48, YTH2348, and Poulan PP22V48 lawn tractors. The high-lift design increases airflow under the deck for better grass clipping discharge, making it ideal for bagging or side-discharge in tall or thick grass.

Fitment & Compatibility

Before buying, confirm your deck measures exactly 48 inches from blade tip to tip. These blades replace OEM part numbers 180054, 539107519, 532173920, and PP24005. They fit Husqvarna YTH24V48, YTH2348, and Poulan PP22V48 models, but also work on many other 48-inch deck tractors from Husqvarna, Poulan, and AYP (American Yard Products). Measure your existing blade length (should be ~20.5 inches) and center hole diameter (5/8 inch or 7/8 inch common—check yours). Verify the blade offset and lift pattern match your deck’s spindle orientation; high-lift blades can conflict with low-clearance or mulching-only decks.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket wrench, torque wrench (recommended 70–90 ft-lbs), and a blade removal tool or block of wood to prevent spinning. Always disconnect the spark plug first.
• Quality: Aftermarket blades, but rated 4.9/5 from 30 reviews. They’re typically made from heat-treated steel, but may not be as thick as OEM. Check for sharpness out of the box—some users report needing to sharpen before first use.
• Common gotcha: High-lift blades create more vibration on uneven decks. If your deck is bent or spindles are worn, you may notice increased noise or poor cut quality. Also, they’re not recommended for mulching—use standard or mulching blades for that.
• 3-pack value: At ~$6.66 per blade, it’s cheaper than buying OEM singles. Replace all three at once for even wear and consistent cut.

Should You Buy It

If you have a 48-inch deck Husqvarna or Poulan tractor and primarily bag or side-discharge in dense grass, this 3-pack is a solid, budget-friendly upgrade. Skip it if you mostly mulch, have a deck under 48 inches, or want OEM-grade thickness.
