2 Pack 532134149 Lawn Mower Blades with Bolts for YTH18542, Z242F Replaces 532138971, 532138498, 422719, 21546095, Husqvarna 42 Inch Mower Blades, Craftsman 42 Inch Mower Blades, High Lift

What It Is

This is a 2-pack of 42-inch high-lift lawn mower blades with bolts, designed for residential riding mowers. The high-lift design increases airflow for better grass clipping discharge, making it ideal for bagging or side-discharge mowing on medium to large lawns.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 42 inches wide. These blades replace OEM part numbers 532138971, 532138498, 422719, and 21546095. They fit Husqvarna YTH18542, Z242F, and Craftsman 42-inch mowers (including models like 917.289340). Measure your existing blade length, width, and center hole diameter (usually 1 inch) to verify. Check that your spindle bolt pattern matches—these come with bolts, but ensure they thread into your mower’s spindle. Not all Craftsman 42-inch decks are identical; cross-reference your mower’s model number with the listed OEM numbers.

Key Things to Know

• Quality: Aftermarket high-lift blades; some users report they’re slightly thinner than OEM, which may reduce lifespan on rough terrain.
• Installation: Easy with basic tools (socket wrench). The included bolts are a plus, but torque to manufacturer specs (typically 70-90 ft-lbs) to avoid loosening.
• Gotchas: High-lift blades can cause more engine strain and vibration on some mowers. If you mostly mulch, consider a different blade style—these are optimized for bagging.
• Balance: Check blade balance after installation; inexpensive blades sometimes need minor filing to avoid wobble.

Should You Buy It

If you need a budget-friendly replacement for bagging or side-discharge mowing on a 42-inch Husqvarna or Craftsman riding mower, this 2-pack offers good value. It’s not ideal for mulching or heavy-duty commercial use, but for average residential lawns, it gets the job done.
