Aeagle 138971 Mower Blades for Craftsman LT1000 LT2000 T110 YT3000 Husqvarna YTH22V42 YTH18542 YTA18542 YTH1542XP 42 inch Deck Zero Turn 138498 532138971, Medium Lift, 5 Point Star, 2 Pack Blue

What It Is

The Aeagle 138971 is a set of two medium-lift, 5-point star mulching blades designed for 42-inch cutting decks on popular Craftsman and Husqvarna lawn tractors and zero-turn mowers. These blades are for standard grass cutting and mulching, not bagging or heavy-duty commercial use.

Fitment & Compatibility

Before buying, verify these three things:

• Deck size: Fits only 42-inch decks. Measure your deck width to confirm.
• OEM part cross-reference: Replaces Craftsman/Husqvarna OEM part numbers 138971, 532138971, and 138498. Check your owner’s manual or current blade for these numbers.
• Model compatibility: Confirmed for Craftsman LT1000, LT2000, T110, YT3000 series, and Husqvarna YTH22V42, YTH18542, YTA18542, YTH1542XP. Not all 42-inch decks use the same blade—check your model list before ordering.

Measurement specs: Blade length is approximately 20.5 inches (center hole to tip), with a 5-point star center hole. If your original blade has a different hole pattern or length, this won’t fit.

Key Things to Know

• Quality vs. OEM: These are aftermarket blades. They cut well but may not last as long as factory OEM blades in rocky or sandy soil. Inspect for balance out of the box—some users report needing to balance them before installation.
• Installation difficulty: Easy. Use a socket wrench and blade removal tool. Torque to 50-70 ft-lbs. Always disconnect the spark plug first.
• Common gotcha: The 5-point star hole fits most Craftsman and Husqvarna spindles, but some older models use a different center hole shape. Measure your blade’s center hole diameter (about 1 inch) and shape before ordering.
• Medium lift: Good for mulching and standard cutting. Not ideal for thick, wet grass or bagging—those need high-lift blades.

Should You Buy It

Buy these if you need a budget-friendly replacement for a 42-inch Craftsman or Husqvarna tractor and primarily mulch or cut dry grass. Skip them if you have an older deck with a non-standard spindle or need heavy-duty commercial durability—stick with OEM or high-lift blades for those cases. For $22.88, they’re a solid value for light to moderate residential use.
