What It Is

This is a set of three 48-inch replacement blades designed for Husqvarna 48-inch lawn tractors and zero-turn mowers. They cut grass by lifting and shearing against a deck’s air flow, and they fit models like the Z248F, YTH24V48, and others using OEM part numbers 173921 or 532173921.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 48 inches wide (measure from blade tip to blade tip). These blades replace OEM part 173921 (also listed as 532173921) and fit Husqvarna models including Z248F, 2448, YTH24V48, YTH24K48, Z248, YTH2448, and YTH2348. They are aftermarket parts, not genuine Husqvarna, so check your owner’s manual or current blade part number. Also verify the center hole is 1-inch diameter (common for Husqvarna) and the blade length is 16 inches each (three blades total for a 48-inch deck). If your deck uses a different spindle or blade pattern (e.g., some Craftsman or Poulan models), these won’t work.

Key Things to Know

• Quality: Rated 4.6/5, but some users report they may require balancing out of the box. Use a blade balancer before installing.
• Installation: Easy for DIYers—remove the old blade, clean the spindle, and torque to 70–90 ft-lbs (check your manual). Use a block of wood to prevent spindle rotation.
• Common gotcha: These are not “mulching” blades; they produce side-discharge or bagging results. If you want finer clippings, look for gator-style blades.
• Durability: They are made from hardened steel but may dull faster than OEM blades on rocky or sandy soil. Sharpen after 10–15 hours of use.

Should You Buy It

If you need a budget-friendly, direct replacement for a Husqvarna 48-inch deck and you’re comfortable with basic blade maintenance (balancing, torquing), these are a solid value at $25.88. They’re not for heavy-duty commercial use or mulching, but for residential mowing on standard turf, they’ll cut cleanly and save you money over OEM.
