Replacement 187254 Medium Lift Blades Set, Compatible with 54" Deck Hu sqvarna GTH26K54T MZ5424S RZ5424 AYP Pou LAN Craftsman Lawn Mower, Replaces 187256 21546235 532187254 532187256, 3 Pack

What It Is

This is a three-piece set of medium-lift replacement blades designed for 54-inch cutting decks on Husqvarna, AYP, Poulan, Craftsman, and other compatible lawn tractors. The medium-lift profile balances bagging performance with decent mulching and side discharge, making it a general-purpose choice for residential mowing.

Fitment & Compatibility

Before buying, confirm these three things:

1. Deck size: Must be exactly 54 inches. Measure blade tip to tip across the deck, not the mower body.
2. Mounting pattern: These blades use a center hole and two offset pins. Check your existing blade’s hole pattern. If it has a single center hole with no pins, these won’t fit.
3. Model cross-reference: Fits Husqvarna GTH26K54T, MZ5424S, RZ5424; AYP/Poulan/Pro models with 54” deck; Craftsman models using OEM 532187254, 532187256, 21546235. Not compatible with 46” or 48” decks or zero-turns with different spindle patterns.

Measure blade length (should be ~20.5 inches tip to tip) and center hole diameter (~5/8 inch) to be certain.

Key Things to Know

• Installation difficulty: Easy with a socket wrench and blade removal tool. Expect 20–30 minutes for all three. Use thread locker on spindle bolts.
• Lift vs. cut quality: Medium lift means decent grass pickup in dry conditions but may struggle in wet or tall grass. If you bag often, consider high-lift blades instead.
• Balance check: Aftermarket blades sometimes arrive slightly out of balance. Spin each blade on a nail or use a balancer before installing to avoid vibration and spindle wear.
• Wear life: Typically 25–50 hours of mowing depending on debris and terrain. Sharpen or replace when edges round or nicks appear.

Should You Buy It

Buy this set if you need a direct, affordable replacement for your 54-inch Husqvarna/AYP/Craftsman deck and want a reliable medium-lift blade that works for general mowing—not heavy bagging or mulching. The price is fair for a three-pack, and the 4.7-star rating indicates consistent quality. If your deck uses a different mounting pattern or you need high-lift performance, skip this set.
