3PCS 173920 561735B Z248F 48" Lawn Mower Blades Compatible with Husqvarna YTH24V48 YTH2348, for Cut Craftsman, Poulan Mowers Replaces OEM #'s 173920, 180054, PP24005, 532180054

What It Is

This is a set of three 48-inch lawn mower blades designed to replace OEM parts on Husqvarna, Craftsman, and Poulan mowers with 48-inch cutting decks. They’re for residential use, suited for medium-to-large lawns, and work with both bagging and mulching setups.

Fitment & Compatibility

Before buying, confirm your mower’s deck size is exactly 48 inches—these won’t fit 42-inch or 54-inch decks. They’re compatible with Husqvarna YTH24V48 and YTH2348, plus select Craftsman and Poulan models using OEM #173920, 180054, PP24005, or 532180054. Measure your old blade’s length (should be ~20 inches), center hole diameter (usually 1 inch), and thickness (about 0.25 inches). These are aftermarket, so they may differ slightly from OEM in weight or finish—check that the spindle pattern matches (typically a 5-point star or round hole with offset). Verify your deck’s blade mount type (single or double bolt) before installing.

Key Things to Know

• Quality: Made from heat-treated steel, but may be lighter or thinner than OEM blades—expect slightly shorter lifespan if mowing heavy grass or debris.
• Installation: Easy DIY job with a socket wrench and blade removal tool. Torque bolts to 70-90 ft-lbs. Mark blade orientation before removal to avoid imbalance.
• Gotchas: These are universal-fit; some users report needing to file the center hole for a perfect fit on certain spindles. Always check for wobble after install.
• Balance: Aftermarket blades may require balancing—use a blade balancer to avoid vibration and spindle wear.

Should You Buy It

Buy these if you have a compatible 48-inch Husqvarna, Craftsman, or Poulan mower and want an affordable, high-rated replacement for regular mowing. They’re a solid value for residential use but not ideal for commercial-grade durability or heavy-duty conditions—opt for OEM if you need longer life or perfect fitment.
