What It Is

This is a set of two 42-inch replacement mower blades designed for Craftsman, Husqvarna, and compatible lawn tractors and zero-turn mowers with a 42-inch cutting deck. They’re for residential mowing, not heavy commercial use.

Fitment & Compatibility

• Deck size must be exactly 42 inches – measure your deck width (cutting path) to confirm.
• Models: Fits Craftsman LT1000, LT2000, T110, YT3000, DLT3000, T210, T2200, YTS3000, T3000, T130, YS4500, and Husqvarna YTH22V42, YTH18542, YTA18542, YTH1542XP. Also fits many zero-turn mowers with a 42” deck.
• OEM numbers: Replaces Craftsman 138971, 138498, and Husqvarna 532138971, 532138498.
• Check blade length and center hole: These are 42-inch blades (actually ~21 inches each), with a 5-point star center hole. Measure your current blade length and center hole shape (star vs. oval) before buying. If your deck uses a different hole pattern, these won’t fit.

Before buying: Remove one blade and measure length (end to end) and center hole diameter/shape. Confirm your mower model is in the compatibility list above.

Key Things to Know

• Quality: Rated 4.4/5 – generally sharp, balanced, and durable for residential use. Some users report needing to re-sharpen after a few seasons.
• Installation: Moderate difficulty – you’ll need a socket wrench and blade removal tool (or block of wood to prevent spinning). Torque bolts to 70–90 ft-lbs. Always disconnect the spark plug first.
• Common gotchas: These are not universal – if your deck uses a different hole pattern (e.g., oval or diamond), they won’t work. Also, check for deck clearance if you have a mulching kit installed.
• Pack includes 2 blades – enough for a standard 42” deck (some zero-turn decks may need 3 blades; verify your setup).

Should You Buy It

If you own one of the listed Craftsman or Husqvarna 42” deck models and want a direct, affordable replacement without hunting OEM parts, this is a solid choice. It’s not for commercial use or decks with non-standard hole patterns, but for routine residential mowing, it offers good value and reliable performance.
