173920 High Lift Mower Blades Compatible with Hu sqvarna/Craftsman/Pou LAN 48" Cut Deck, 180054 Mower Blade Set Fit for YTH24V48 YTH2348 Lawn Mower, Replace 532180054, 532173920, PP24005, 3 PK

What It Is

This is a set of three high-lift mower blades designed for 48-inch cutting decks on select Husqvarna, Craftsman, and Poulan Pro lawn tractors. High-lift blades create more upward airflow than standard blades, improving grass clipping discharge and bagging performance—ideal for mulching or collecting leaves.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: These blades fit only 48-inch decks. Measure your deck width (blade tip to tip) to confirm.
• Model compatibility: Works with Husqvarna YTH24V48, Craftsman YTH2348, and similar tractors. Check your owner’s manual or current blade part numbers.
• OEM cross-reference: Replaces OEM parts 532180054, 532173920, and PP24005. If your current blades match any of these, these are direct replacements.
• Blade measurements: Each blade is 18.5 inches long, with a 1-inch center hole and 0.5-inch offset. Measure your old blade’s length, hole size, and offset to confirm fit.

Key Things to Know

• Quality: Made from heat-treated steel (not stamped), these are more durable than many OEM blades and resist bending on rocks or roots.
• Installation: Easy swap with a socket wrench. Use a blade removal tool or block the blade with wood to prevent spinning. Torque the bolt to 70-90 ft-lbs.
• Lift performance: High-lift design improves bagging and side-discharge but increases engine load slightly—expect a small drop in fuel efficiency.
• Gotcha: These blades are not for mulching decks that require a specific low-lift or mulching blade. If you have a dedicated mulching setup, stick with OEM or low-lift blades.

Should You Buy It

Buy this set if you have a 48-inch Husqvarna/Craftsman/Poulan Pro lawn tractor and want better bagging or leaf collection without paying OEM prices. The high-lift design works well for tall grass or heavy debris, but don’t use them if your deck is designed for low-lift mulching blades—you’ll get poor cut quality and excessive wear.
