Replacement High Lift Blades for 187254 187256 532187254 532187256 574292401 - Compatible with Husqvarna Z254 MZ54 LGT2554 RZ5424 AYP Craftsman Lawn Mower - 54" Deck (3 Pack)

What It Is

This is a 3-pack of aftermarket high-lift blades designed for 54-inch cutting decks on Husqvarna, AYP, Craftsman, and compatible lawn tractors/zero-turns. High-lift blades create stronger airflow to improve grass discharge and bagging performance, ideal for thick or wet grass.

Fitment & Compatibility

• Deck Size: Only fits 54-inch decks. Measure your deck’s cutting width before buying—if it’s not exactly 54", these won’t work.
• OEM Part Cross-Reference: Replaces Husqvarna/Craftsman/AYP part numbers 187254, 187256, 532187254, 532187256, and 574292401.
• Model Match: Compatible with Husqvarna Z254, MZ54, LGT2554, RZ5424, and similar Craftsman/AYP models with a 54" deck. Check your mower’s model number against the seller’s list.
• Measurements: Each blade is approximately 20.5" long, 2.5" wide, with a 1" center hole and 7/16" star/oval drive hole. Verify your spindle’s hole pattern matches before installation.

Key Things to Know

• Quality: Aftermarket blades may be slightly thinner or less balanced than OEM. Expect moderate durability—fine for residential use, but not for heavy commercial mowing.
• Installation Difficulty: Easy if you have a socket set and a torque wrench. Always torque to 50-70 ft-lbs and use thread locker to prevent loosening.
• Common Gotcha: High-lift blades require more engine power and can cause clumping in dry, dusty conditions. They also increase noise and vibration—check your mower’s spindle bearings for wear beforehand.
• Pack Contents: Comes as 3 blades, no hardware. Reuse your existing washers, bolts, and nuts.

Should You Buy It

Buy this if you own a 54" Husqvarna, Craftsman, or AYP mower and need a budget-friendly upgrade for better bagging or discharge in thick grass. Skip it if you need OEM-grade balance for a commercial mower or if your deck is smaller than 54".
