Replacement 173920 High Lift Mower Blades, Compatible with 48" Cut Craftsman Hu sqvarna Pou LAN GTH YTH 2148 2448 Lawn Mower, Replace for 180054 532180054 532173920 PP24005, 3 PACK

What It Is

This is a set of three high-lift mower blades designed for 48-inch cutting decks on select Craftsman, Husqvarna, Poulan, and GTH/YTH lawn tractors (models like 2148, 2448). The high-lift profile increases airflow for better grass clipping discharge and bagging performance, especially in thick or tall grass.

Fitment & Compatibility

Before buying, verify your deck is exactly 48 inches wide (measure center-to-center of blade mounting holes). These blades replace OEM part numbers 180054, 532180054, 532173920, and PP24005. They fit many Craftsman, Husqvarna, Poulan, and GTH/YTH series tractors, but not all—cross-check your mower’s model number against the compatibility list. Measure your old blade’s length (should be ~16-18 inches) and center hole diameter (typically 1 inch or 7/16 inch). Aftermarket blades may have slight thickness or balance differences from OEM.

Key Things to Know

• Installation: Straightforward with basic tools (socket wrench, torque wrench). Always disconnect spark plug wire first. Torque bolts to 70-90 ft-lbs.
• Quality: High-lift design improves bagging but may create more vibration if blades are out of balance. Check balance before installing.
• Gotchas: High-lift blades increase deck power draw—if your mower struggles in light grass, this may worsen it. Not ideal for mulching; they throw clippings out rather than recutting them.
• Durability: Heat-treated steel holds edge decently, but expect to sharpen or replace after 25-30 hours of use on rough terrain.

Should You Buy It

If you need a budget-friendly three-pack for a 48-inch deck tractor and prioritize bagging or side-discharge performance over mulching, this is a solid value at $23.99. It’s a direct fit for many Craftsman and Husqvarna models, but double-check your mower’s model number and old blade measurements to avoid returns. Best for homeowners with average-sized lawns who want reliable, no-frills replacement blades.
