Lawn Mower Blades with 54" Deck Fit for Craftsman Husqvarna Poulan Mowers Replaces OEM 187254 187256 and 532187256 Set of 3

What It Is

This is a set of three replacement blades designed for 54-inch cutting decks on Craftsman, Husqvarna, and Poulan lawn tractors. They’re meant for mulching or standard bagging/discharge mowing and replace OEM part numbers 187254, 187256, and 532187256.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: Must be exactly 54 inches. Measure your blade span if unsure.
• Brand and model: Fits most Craftsman (LT1000/2000/3000 series), Husqvarna (YTH, GTH, LTH series), and Poulan (Pro, PP, PB series) tractors with 54” decks. Check your model number against the OEM parts listed.
• Blade measurements: These blades are 18.5 inches long, 2.5 inches wide, with a 0.25-inch thickness and a 5/8-inch center hole. Measure your old blade’s length and hole size to be safe. Aftermarket blades may have slightly different air lift or balance than OEM—verify they match your deck’s spindle pattern.

Key Things to Know

• Quality: Aftermarket steel, not OEM. Works fine for most homeowners, but may dull faster than premium brands like Oregon or Stens.
• Installation: Straightforward if you have a torque wrench and a blade removal tool. Tighten to 70–90 ft-lbs. Use thread locker if your spindles are worn.
• Common gotcha: The set includes three identical blades. Some decks use a different blade for the center spindle (e.g., a mulching blade). If your deck requires a specific center blade, this set may not work.
• Balance: These are often pre-balanced, but always check with a blade balancer before installing to avoid vibration.

Should You Buy It

Buy this if you own a Craftsman, Husqvarna, or Poulan 54” deck tractor, want a budget-friendly replacement, and don’t mind aftermarket quality for typical home lawn care. Skip it if you need OEM durability for heavy commercial use or require a specific center blade design.
