What It Is

This is a 3-pack of high-lift notched mower blades designed to replace OEM part numbers 532187256, 539112053, 187254, and 11180. They are intended for use on Husqvarna, Craftsman, and Poulan Pro zero-turn and lawn tractors with 54-inch decks, primarily for aggressive cutting in tall grass, thick turf, or bagging applications.

Fitment & Compatibility

• Deck size: Only for 54-inch cutting decks. Do not use on 46-inch, 48-inch, or 50-inch decks.
• Blade dimensions: 20.5 inches long, 2.75 inches wide, 0.25 inches thick, with a 5-point star center hole (1-inch diameter). Confirm your deck’s blade length and hole shape match.
• OEM cross-reference: Directly replaces Husqvarna/Craftsman/Poulan part numbers 532187256, 539112053, 187254, and 11180.
• Compatible models (partial list): Husqvarna Z254, YTH2454, YTH24v54; Craftsman ZT 7000, ZT 7500; Poulan Pro RZ5424, RZ5426; LGT 2554, 2654. Always verify your specific model and deck size before ordering.
• Aftermarket vs OEM: These are aftermarket blades, not genuine OEM. They are generally fine for most residential use but may differ slightly in hardness or balance.

Key Things to Know

• High-lift design: The curved, notched profile creates more airflow, improving bagging and clipping discharge. However, it increases drag and may reduce fuel efficiency or strain the engine in wet grass.
• Installation difficulty: Easy – requires a socket wrench and a blade removal tool (or block of wood). Always disconnect the spark plug and remove the key first. Torque blade bolts to 70–90 ft-lbs (check your manual).
• Common gotchas: Notched blades can be noisier than standard blades. They are not ideal for mulching – if you prefer mulching, look for a low-lift or gator-style blade. Also, these blades are not for universal fit; they only work on decks with the 5-point star hole.
• Quality: Based on ratings (4.8/5 from 11 reviews), users report good balance and sharpness out of the box. But as with any aftermarket blade, inspect for warping or burrs before installation.

Should You Buy It

Yes, if you have a 54-inch Husqvarna, Craftsman, or Poulan Pro tractor or zero-turn and need a cost-effective 3-pack for regular bagging or high-lift cutting. Avoid if you require OEM-only parts for warranty reasons, prefer mulching, or have a non-54-inch deck. For the price and rating, it’s a solid value for residential use.
