48" Deck Mower Blades 180054 for Hus qvarna YTH24V48 YTH2348 YTH22K48 YTH23K48 Z248, High Lift Blades Replace for 173920 532180054 539107519, 3 Pack

What It Is

This is a 3-pack of high-lift replacement blades for 48-inch cutting decks, designed to fit Husqvarna YTH and Z200 series lawn tractors. The high-lift design increases airflow for superior grass clipping discharge, making them ideal for bagging or side-discharge mowing in thick or tall grass.

Fitment & Compatibility

Before buying, confirm your mower has a 48-inch deck and that the blade part number matches your model. These blades replace OEM numbers 180054, 173920, and 539107519. They fit Husqvarna YTH24V48, YTH2348, YTH22K48, YTH23K48, and Z248 models. Measure your existing blade length (should be 18.5-19 inches), center hole diameter (typically 1 inch), and thickness (about 0.25 inches). Also check the spindle pattern—these are 5-point star center holes. If your deck uses a different mount or has a smaller center hole, these won’t work.

Key Things to Know

• Quality vs OEM: These are aftermarket blades, not genuine Husqvarna. They use similar steel gauge but may have slightly different balance or coating. Check for warping or burrs before installation.
• Installation difficulty: Easy with a socket wrench and blade removal tool. Always disconnect the spark plug and use jack stands if lifting the mower. Torque bolts to 70-90 ft-lbs.
• Common gotcha: High-lift blades create more upward suction, which can cause scalping on uneven ground if deck height is set too low. They also require more engine power—don’t mow wet, thick grass at full speed.
• Durability: Expect 25-50 hours of use depending on terrain and debris. Sharpen or replace sooner if you hit rocks or roots.

Should You Buy It

If you own a compatible Husqvarna 48-inch tractor and need reliable, affordable replacement blades for bagging or side-discharge mowing, this 3-pack offers good value. It’s best for homeowners who mow weekly and want OEM-like performance without the OEM price. Skip if you have a different deck size or need mulching blades—these are high-lift only.
