8TEN LawnRAZOR Mower Blade Set for Husqvarna YTH2348 YTH24V48 YTH2148 YTH24K48 Z248 YTH2448 48 inch Deck 180054 173920 532180054 (Notched High Lift)

What It Is

This is a set of three notched high-lift blades designed to fit 48-inch cutting decks on select Husqvarna lawn tractors and zero-turn mowers. The high-lift profile increases airflow under the deck for superior grass clipping discharge and bagging performance, making it ideal for taller or thicker grass.

Fitment & Compatibility

Before purchasing, verify your mower has a 48-inch deck and cross-reference the OEM part numbers: 180054, 173920, 532180054. This set fits Husqvarna models including YTH2348, YTH24V48, YTH2148, YTH24K48, Z248, and YTH2448. Measure your existing blade length (should be roughly 20.5 inches from tip to tip), center hole diameter (typically 1 inch), and spindle hole spacing (usually 3 inches on center). Check that your deck uses a three-blade configuration—not two or four. This is an aftermarket replacement, not OEM, so confirm your deck’s blade offset and lift angle match the notched high-lift design.

Key Things to Buy

• Quality: Made from heat-treated boron steel for durability, but may not hold an edge as long as OEM Husqvarna blades in sandy or rocky soil.
• Installation: Straightforward swap—remove old blades with a socket wrench, clean spindle, and torque new bolts to 70-80 ft-lbs. Use thread locker if bolts are loose.
• Common gotcha: High-lift blades create more drag, so they may slightly reduce engine RPM or fuel efficiency on smaller engines (under 20 HP). Ensure your deck belt is in good condition to avoid slippage.
• Balance: Each blade should be balanced before installation. Use a blade balancer—unbalanced blades cause vibration and uneven cuts.

Should You Buy It

If you own one of the listed Husqvarna 48-inch deck models and frequently cut tall, thick, or damp grass, this set offers strong bagging and discharge performance at a budget-friendly price. It’s a solid upgrade over standard low-lift blades, but skip it if you mainly mow dry, manicured lawns where mulching or a lower lift profile is preferred.
