What It Is

This is a set of three high-lift replacement blades designed for Husqvarna 48-inch deck mowers, including zero-turn and lawn tractor models. High-lift blades create stronger airflow to improve grass discharge and bagging performance, making them ideal for thick or damp grass.

Fitment & Compatibility

• Deck size: Only fits Husqvarna 48-inch cutting decks. Measure your deck width to confirm.
• Compatible models: YTH2348, YTH24V48, YTH2148, YTH24K48, Z248, YTH2448, and Z248F zero-turn mowers.
• OEM cross-reference: Replaces Husqvarna OEM part numbers 532180054 and 173920. Aftermarket Grasscool brand.
• Measurements: Blade length is 18.5 inches, center hole diameter 7/8 inch, with a 2-inch offset (verify your spindle pattern).
• Check before buying: Confirm your deck uses three blades (not two) and that your current blades are standard or high-lift style—these won’t work on mulching-only decks without adapter kits.

Key Things to Know

• Installation: Moderate difficulty. You’ll need a socket set and torque wrench (recommended torque: 70-90 ft-lbs). Use thread locker on the spindle bolts.
• Quality: Heat-treated steel with a painted finish. Sharp out of the box, but expect to sharpen after 10-15 hours of use in abrasive grass or sandy soil.
• Gotcha: High-lift blades increase power draw and may cause belt slipping on older or underpowered mowers. If your deck bogs down, switch to standard lift blades.
• Balance: Always check blade balance after sharpening or replacement to avoid vibration and spindle damage.

Should You Buy It

Buy these if you need a budget-friendly, direct-fit replacement for a Husqvarna 48-inch deck and want better bagging or discharge performance than standard blades. They’re a solid value for DIY homeowners with moderate mechanical skills, but skip them if you only mulch or if your mower has a weak transmission.
