2PCS 134149 Blades Compatible with Craftsman 42 Inch LT1000 LT2000 YS4500 Husqvarna Poulan Pro 42'' Muching Blades for Lawn Mowers with 42 Inch Deck Repalce OE 532134149 422719 424752

What It Is

This is a set of two 42-inch mulching blades designed for Craftsman LT1000, LT2000, YS4500, Husqvarna, and Poulan Pro lawn tractors with a 42-inch cutting deck. They replace OEM part numbers 532134149, 422719, and 424752, turning grass clippings into fine mulch for lawn nutrition.

Fitment & Compatibility

Before buying, confirm your mower has a 42-inch deck (measure from blade tip to blade tip). These blades fit most Craftsman, Husqvarna, and Poulan Pro 42-inch tractors from the 2000s onward, but check your deck’s spindle pattern—they use a center hole with a 5-point star or keyed shape. Measure your old blade length (should be ~20.5 inches) and verify the center hole diameter (typically 7/8-inch). These are aftermarket replacements, not OEM Craftsman, but match the original specs. Avoid if your deck is 46-inch or larger, or if you have a zero-turn mower with a different spindle mount.

Key Things to Know

• Quality: Made from heat-treated steel, but may be slightly thinner than OEM blades. Expect 1-2 seasons of normal use before dulling.
• Installation: Easy—remove the center bolt, swap blades, and torque to 40-50 ft-lbs. Use a blade removal tool (or block the blade) to prevent spinning. Always disconnect the spark plug first.
• Mulching vs. Discharge: These are mulching blades with a curved shape and extra cutting edge. They won’t work well for side-discharge or bagging—stick to mulching only.
• Balance: Out of the box, some users report needing to balance blades with a simple balancer tool to avoid vibration. Check before installing.

Should You Buy It

If you have a Craftsman, Husqvarna, or Poulan Pro 42-inch tractor and want a budget-friendly mulching upgrade, this set is a solid choice. It’s not for heavy commercial use or decks outside 42 inches, but for regular residential mowing, the price and reviews (4.6 stars) make it a reliable value over OEM.
