MowerPartsGroup (3) Craftsman Husqvarna Replacement Mower Blades 187254 187256

What It Is

This is a set of three replacement mower blades designed for select Craftsman and Husqvarna riding mowers with 46-inch or 54-inch cutting decks. They are intended for mulching, bagging, or side-discharge use and match OEM part numbers 187254 and 187256.

Fitment & Compatibility

Before buying, verify three things: deck size (46" or 54"), blade length (check your current blade—these are typically 16.5" or 20.5" depending on the set), and center hole shape (these use a 5-point star center hole, not a round hole). Confirm your mower model number (e.g., Craftsman 917.xxxxx or Husqvarna YTH series) against the listing’s compatibility chart. These are aftermarket blades, not OEM Craftsman/Husqvarna, so tolerances may vary slightly—measure your existing blade’s length and thickness to compare.

Key Things to Know

• Quality: Made from heat-treated steel, but some users report they are slightly lighter than OEM blades. Durability is adequate for residential use, not commercial.
• Installation: Straightforward—remove the old blade, note the washer orientation, and torque the bolt to 70-90 ft-lbs. Use a blade removal tool or block of wood to prevent spinning.
• Common gotcha: The 5-point star hole can be a tight fit on some spindles; file the hole lightly if needed. Always replace blades in sets of three to maintain balance.
• Sharpening: These are not hardened for extended sharpening—replace when dull or after 25 hours of use.

Should You Buy It

If you need to replace all three blades on a 46" or 54" Craftsman or Husqvarna riding mower and want a budget-friendly aftermarket option that works for typical residential mowing, this set is a solid choice. Avoid if you require OEM fitment for a commercial mower or if your deck uses a different center hole shape.
