What It Is

A 3-pack of replacement mulching blades for 48-inch deck lawn tractors, designed to chop grass clippings finely for natural lawn fertilization. Compatible with AYP, Poulan, Craftsman, and Husqvarna models, including YTH2348, YTH24V48, YTH2248B, and YTH23K48.

Fitment & Compatibility

Before buying, verify three things:

• Deck size: These blades fit only 48-inch cutting decks. Measure your deck width (blade tip to tip) if unsure.
• Model numbers: Confirm your mower model (e.g., YTH2348) and check the OEM part numbers: 180054, 173920, PP24005, 532180054, 532173920, 539107519. Cross-reference with your owner’s manual or current blade part number.
• Blade dimensions: Each blade is approximately 20.5 inches long, with a 5-point star center hole and 0.25-inch thickness. Measure your old blade’s length and center hole shape to ensure a match. These are aftermarket replacements, not OEM Craftsman, but built to OEM specs.

Key Things to Know

• Quality: Made from heat-treated steel with a painted finish. Expect decent durability for residential use, but not as thick as some premium OEM blades.
• Installation difficulty: Easy with basic tools (socket wrench and torque wrench). Use a blade removal tool or block the blade with wood to prevent spinning. Torque the center bolt to 70-80 ft-lbs.
• Common gotcha: Mulching blades require a high-lift design to recirculate clippings. If your deck has a side-discharge chute, remove it or install a mulching plug (not included) for proper mulching.
• Performance: Best with dry grass. Wet or tall grass may clog the deck—mow more frequently or at a higher cut setting.

Should You Buy It

Buy if you own a 48-inch deck tractor from AYP, Poulan, Craftsman, or Husqvarna with the listed OEM part numbers, and you want an affordable 3-pack for mulching. It’s a solid value for residential mowing, but if you need OEM-grade toughness for heavy commercial use, consider spending more on genuine Craftsman or Husqvarna blades.
