This is a 2-pack of 42-inch 3-in-1 mulching blades designed for Craftsman LT1000/LT2000 series riding mowers and select Husqvarna models (YTH18542, YTA18542). They replace OEM part numbers 532134149 and 532138498, offering mulching, bagging, and side-discharge capability.
Fitment & Compatibility
Before buying, confirm your mower deck is exactly 42 inches (measured cutting width, not housing). These blades use a 5-star center mounting hole—common on Craftsman and Husqvarna decks but different from oval or diamond holes. They fit:
- Craftsman LT1000, LT2000 (with 42" deck)
- Husqvarna YTH18542, YTA18542
- Also compatible with many Poulan, Murray, and AYP models using the same 5-star pattern.
Check your current blade’s center hole shape and measure length (center-to-center) to verify 42 inches. These replace OEM #532134149 and #532138498.
Key Things to Know
- 3-in-1 design: Works for mulching, bagging, or side-discharge—no need to swap blades for different cutting modes.
- Installation tip: Use a blade removal tool or block the blade to prevent spinning. Torque bolts to 70–90 ft-lbs. Left-hand threads on some models; check your manual.
- Quality: Aftermarket blades may be slightly thinner than OEM but are heat-treated for durability. Sharp edges out of the box—handle with gloves.
- Balance: Always balance new blades before mounting to avoid vibration and spindle wear. A $10 balancer is worth it.
Should You Buy It
If you own a Craftsman LT1000/LT2000 or Husqvarna YTH18542/YTA18542 with a 42-inch deck and need a budget-friendly mulching blade set, this is a solid pick. The 5-star mount ensures secure fitment, and the 3-in-1 design adds flexibility. At $26.99 for two blades, it’s a good value for DIY homeowners who mow regularly. Not ideal if your deck uses a different mounting pattern or you need heavy-duty commercial blades.
