ACEBRI Mulching Blades 42 '' for Ariens 21546095, 42 '' for Craftsman 127843, 134149, 138498, for Craftsman LT2000 LT1000 532134149 for Husqvarna 42'' mulching Riding Mower Blades(5 Point Star), 2Pack

What It Is

These ACEBRI 42-inch mulching blades (5-point star design) are aftermarket replacements for select Ariens, Craftsman, and Husqvarna riding mowers. They’re built to chop clippings finer for grass recycling, not bagging or side-discharge.

Fitment & Compatibility

Before buying, confirm three things:

• Deck size: Must be exactly 42 inches (measured blade tip to tip).
• OEM cross-reference: Fits Ariens 21546095, Craftsman 127843, 134149, 138498, and 532134149 (used on LT2000, LT1000). Also fits Husqvarna 42-inch mulching decks.
• Physical check: Measure your old blade’s center hole diameter (usually 1-inch or 5/8-inch), overall length, and offset. These blades have a 5-point star pattern—verify your spindle matches. Aftermarket blades may vary slightly from OEM shape; test fit before torquing.

Key Things to Know

• Quality: 4.4 stars from 68 reviews suggests decent steel, but some users report balance issues out of the box. Check with a balancer or mark and file if needed.
• Installation: Easy swap if you have a socket wrench and jack stands (or block the deck). Use a torque wrench—specs are typically 70-90 ft-lbs, but check your manual.
• Mulching only: These will not bag or discharge well. If you switch between modes, keep your original blades.
• Common gotcha: The 5-point star pattern may not fit older Craftsman spindles with standard 3-point or oval holes. Inspect your spindle before ordering.

Should You Buy It

If you have a compatible 42-inch Ariens, Craftsman, or Husqvarna (LT1000/LT2000 series) and want a budget-friendly mulching upgrade, these are a solid pick. Skip them if you need bagging blades or have an odd spindle pattern—stick with OEM for guaranteed fit.
