2 Pack 134149 Craftsman 42 inch Mower Blades with 532193003 Bolts Replaces 422719 138498 532134149 532138971 for Craftsman LT2000, Husqvarna YTH18542 YTH2042 YTH150 YTH1542 Tractors, High Lift

What It Is

This is a 2-pack of 42-inch high-lift mower blades with two 532193003 bolts, designed for residential lawn tractors. The high-lift design improves grass clipping discharge and bagging performance, making it ideal for decks with side discharge or bagging systems.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 42 inches (cutting width). These blades replace OEM part numbers 134149, 422719, 138498, 532134149, and 532138971. They fit Craftsman LT2000 series and Husqvarna models YTH18542, YTH2042, YTH150, and YTH1542. Also compatible with many other Craftsman, Husqvarna, Poulan, and AYP tractors using a 42-inch deck. Measure your existing blade length (42 inches tip-to-tip) and center hole diameter (typically 1 inch) to verify. Check that your spindle bolt pattern matches—these use two bolts per blade (included). Not for zero-turn mowers or decks under 42 inches.

Key Things to Know

• Quality: Aftermarket blades, not OEM Craftsman. Some users report thinner metal or shorter lifespan than originals—inspect for warping after first use.
• Installation: Easy swap with basic tools (socket wrench). Use included bolts; torque to 50-60 ft-lbs. Always lift and block the mower deck safely.
• Gotchas: High-lift blades create more suction, which can strain the engine on thick grass. Also, they may not fit decks with built-in blade stoppers or stabilizers—check clearance.
• Balance: After installation, balance the blades on a balancer to avoid vibration and spindle damage.

Should You Buy It

Buy this if you need an affordable, direct replacement for a 42-inch Craftsman or Husqvarna tractor and prioritize bagging or side-discharge performance. Skip it if you want OEM durability, have a deck smaller than 42 inches, or need mulching blades (these are high-lift, not for mulching).
