8TEN LawnRAZOR Mower Blade Set for AYP Husqvarna LT LTH 130 1542 1842 42 Inch Deck 134149 138971 532134149 (Mulching)

What It Is

The 8TEN LawnRAZOR Mower Blade Set is a three-blade mulching kit designed for 42-inch cutting decks on AYP (American Yard Products) and Husqvarna LT/LTH series tractors. It replaces OEM blades 134149, 138971, and 532134149, optimized for mulching grass clippings into fine particles to return nutrients to your lawn.

Fitment & Compatibility

• Deck size: Only fits 42-inch decks (measure your deck width from side to side).
• Models: Works with Husqvarna LT130, LTH130, 1542, 1842, and similar AYP-built tractors (e.g., Poulan, Craftsman, Murray).
• OEM cross-reference: Replaces Husqvarna 134149, 138971, 532134149; also fits John Deere 42-inch decks using these same numbers.
• Check before buying: Measure blade length (should be ~20.5 inches for 42-inch decks), center hole diameter (1 inch), and ensure your spindle pattern matches the three-blade design. Confirm your deck is genuine 42-inch—not 46 or 48-inch—or these blades won’t fit.
• Note: Not for zero-turn mowers or decks with different spindle hole patterns.

Key Things to Know

• Quality: Heat-treated steel with a coated finish for rust resistance; sharp out of the box but may dull faster than premium OEM blades on rocky terrain.
• Installation: Moderate difficulty—requires a socket wrench and blade removal tool (or block wood to prevent spinning). Torque bolts to 70-90 ft-lbs. Left-hand threads on some spindles? Check your manual.
• Mulching vs. bagging: These have a high-lift design for mulching; if you bag clippings, they may leave clumps in wet grass.
• Gotcha: Not all 42-inch decks use the same blade pattern—verify your spindle count (three blades) before buying. Some older AYP decks use two blades.

Should You Buy It

If you own a 42-inch AYP/Husqvarna LT/LTH series mower and want a budget-friendly mulching blade set with solid 4.6-star reviews, this is a reliable choice for average residential lawns. Skip it if you need premium durability for rocky, rough, or commercial use, or if your deck uses a different blade pattern.
