187254 High-Lift Lawn Mower Blade for 54 inch Deck, Fits for Husqvarna RZ5424 Z254, Replaces for 187256 594892901 532187255, 3 Pack

What It Is

A set of three high-lift lawn mower blades designed for 54-inch cutting decks, intended for improved grass clipping discharge and bagging performance on Husqvarna zero-turn mowers and compatible models.

Fitment & Compatibility

• Deck size: 54-inch decks only. Measure your deck width before ordering.
• Direct fit models: Husqvarna RZ5424, Z254, and other 54-inch deck ZT models using OEM part numbers 187254, 187256, 594892901, or 532187255.
• OEM cross-reference: Replaces Husqvarna OEM blades 187254 and 187256. Also fits some AYP/Electrolux-built units with the same spindle pattern.
• Measurements: Blade length is approximately 20.5 inches, center hole is 7/8-inch diameter, and the drive pin hole spacing is 2.75 inches. Verify these against your current blade.
• What to check: Confirm your deck spindle pattern (three-bolt star vs. two-pin), and ensure your deck is 54 inches (not 48 or 60). Not for Craftsman, John Deere, or Toro unless they share the same OEM part numbers.

Key Things to Know

• High-lift design: Creates more airflow for superior bagging and side discharge, but increases engine load slightly. Not ideal for mulching unless you swap to a mulching blade.
• Installation difficulty: Easy—requires a socket wrench and torque to 70-90 ft-lbs. Use thread locker if your spindles are worn.
• Common gotcha: These blades are thinner (0.1875 inches) than some aftermarket options. Check for bent spindles if you hit obstacles.
• 3-pack value: Priced at ~$8.66 per blade, competitive with OEM singles. Replace all three at once for balanced cutting.

Should You Buy It

If you own a Husqvarna 54-inch zero-turn with model numbers listed above and need reliable high-lift blades for bagging or side discharge, this 3-pack offers a solid OEM-alternative at a fair price. Avoid if you primarily mulch or use a different brand deck.
