What It Is

This is a set of three 42-inch high-lift mower blades designed to replace OEM part numbers 532138971, 138971, 532127843, 127843, 532138498, and 138498. They are intended for use on Craftsman, Husqvarna, and Poulan lawn tractors with 42-inch cutting decks, primarily for bagging or side-discharge applications where improved grass lift and airflow are needed.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: Your mower must have a 42-inch cutting deck. Measure if unsure—blade length is critical.
• Model compatibility: These fit many Craftsman LT1000, LT2000, LT125, LTH130, YT3000, YTH22V42, YTH18542, YTA18542, and YTH1542XP models, plus Husqvarna and Poulan equivalents with 42-inch decks. Check your mower’s model number against the list.
• Blade specs: Each blade is 21 inches long, with a 1-inch center hole and 7-point star drive. Center hole diameter and drive pattern must match your spindle. OEM part numbers listed above are direct cross-references—these are aftermarket replacements.

Key Things to Know

• High-lift design: The curved shape creates more suction, improving grass clipping discharge and bagging performance, but increases engine load slightly.
• Installation difficulty: Easy—requires a socket wrench and blade removal tool or block of wood to prevent blade spin. Always disconnect spark plug and tip mower safely.
• Quality note: Aftermarket blades may be slightly thinner or lighter than OEM. Check for balance—if you feel vibration after install, the blade may need balancing.
• Gotcha: High-lift blades are not ideal for mulching; they push clippings out rather than recirculating them. Use standard or mulching blades if you want to leave clippings on the lawn.

Should You Buy It

If you have a 42-inch Craftsman, Husqvarna, or Poulan tractor and want better bagging or side-discharge performance without paying OEM prices, these blades are a solid, cost-effective choice. They’re best for users who frequently bag clippings or mow tall grass. Skip them if you primarily mulch—you’ll get better results with a dedicated mulching blade set.
