187256 Medium Lift Blades for 54" Deck, 187254 Lawn Mower Blades Compatible with Hus-qvarna GTH26K54T MZ5424S RZ5424 AYP Pou-lan Craftsman Lawn Mower, Replaces 21546235, 532187254, 532187256, 3 Pack

What It Is

This is a 3-pack of medium-lift mower blades designed for 54-inch cutting decks. They are meant for medium-duty residential mowing—good for general grass cutting but not ideal for heavy mulching or bagging.

Fitment & Compatibility

• Deck size: Only fits 54-inch decks. Measure your deck width before buying.
• Models: Compatible with Husqvarna GTH26K54T, MZ5424S, RZ5424; also AYP, Poulan, Craftsman models using a 54" deck.
• OEM numbers: Replaces 21546235, 532187254, 532187256. Check your current blade’s part number.
• Measurements: Center hole diameter 7/8"; blade length ~19.5". Confirm your blade’s hole size and length match.
• Aftermarket: These are aftermarket, not OEM Craftsman. Quality is generally fine for most users, but if you need exact OEM specs, verify dimensions yourself.

Key Things to Know

• Medium lift means okay for normal grass but not great for thick, wet grass or heavy mulching.
• Installation: Simple swap with a socket wrench. Note blade orientation—cutting edge faces the direction of rotation.
• Balance: Check balance after install (hang blade on a nail). A cheap blade balancer can prevent vibration and deck damage.
• Sharpness: They come sharp but not razor-sharp. Expect decent edge retention for a season of regular mowing.

Should You Buy It

If you have a 54" deck Husqvarna, Craftsman, or AYP mower and need a budget-friendly 3-pack for standard residential mowing, this is a solid value. Skip it if you need heavy mulching or bagging performance—look for a high-lift or mulching blade instead.
