134149 42'' Blade Mulching Set for Craftsman LT1000 LT2000 YS4500 Husqvarna Poulan Pro 42 inch Lawn Mower Replaces 422719 777134149 424752 532134149 5 Point Star (2 Pack)

What It Is

This is a 42-inch mulching blade set designed for several popular riding lawn mower brands. The 5-point star center hole fits specific spindle assemblies, and the blades are intended to cut grass into fine clippings for natural lawn feeding.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch cutting deck. This set replaces OEM part numbers 422719, 777134149, 424752, and 532134149. It fits Craftsman LT1000, LT2000, YS4500, Husqvarna, and Poulan Pro models with a 42-inch deck and a 5-point star spindle. Measure your existing blade length and center hole shape. If you have a different deck size or a round center hole, this won’t work. Cross-check your mower’s model number against the manufacturer’s blade compatibility chart.

Key Things to Know

• Installation difficulty: Moderate. You’ll need a socket wrench, torque wrench, and jack or ramps to lift the mower safely. Always disconnect the spark plug first.
• Mulching vs. bagging: These blades are optimized for mulching. If you regularly bag or side-discharge, consider a universal or hybrid blade set instead.
• Quality: Aftermarket blades at this price point are generally good for residential use. Expect slightly less longevity than OEM, but they perform well for the cost.
• Common gotcha: The 5-point star hole must align perfectly with your spindle. If your mower uses a different spindle design (e.g., 6-point or oval), these won’t fit.

Should You Buy It

This set is a solid, budget-friendly choice if you own a compatible 42-inch Craftsman, Husqvarna, or Poulan Pro mower and primarily mulch. It’s not for heavy commercial use or mowers with non-5-point spindles. If you need bagging or side-discharge performance, look elsewhere. For most homeowners with the right deck, it’s a reliable replacement.
