134149 Mulching Blades, Lawn Mower Blade Compatible with Craftsman LT1000 LT200, Husqvarna, Poulan Pro 42 inch Deck Riding Mower Lawn Tractor, Replace Number for 424752 532134149, 5 Point Star (2 Pcs)

What It Is

This is a set of two mulching blades designed for 42-inch deck riding mowers, including Craftsman LT1000/LT200 series, Husqvarna, and Poulan Pro models. They replace OEM part numbers 424752 and 532134149, featuring a 5-point star center hole for precise mounting.

Fitment & Compatibility

Before buying, verify your mower has a 42-inch deck—this is non-negotiable. The 5-point star center hole fits specific spindle designs found on Craftsman LT1000, LT200, Husqvarna, and Poulan Pro tractors. Measure your current blade length (should be roughly 20.5 inches) and ensure the blade width and thickness match. Cross-check your OEM part number against 424752 or 532134149. If your deck is smaller or larger, or your spindle uses a different hole pattern, these blades won’t fit.

Key Things to Know

• Quality: Made from heat-treated steel with a painted finish. They’re durable but may not hold an edge as long as premium OEM blades.
• Installation: Moderate difficulty—requires a socket wrench and possibly a blade removal tool. Always use a torque wrench to tighten to manufacturer specs (typically 70-80 ft-lbs).
• Common gotchas: The 5-point star alignment must be exact; forcing it can damage the spindle. Also, these are mulching only—they won’t bag or side-discharge effectively.
• Balance check: After installation, test blade balance to avoid vibration that can damage the spindle or deck.

Should You Buy It

If you own a compatible 42-inch deck tractor and want an affordable mulching upgrade for grass clipping recycling, this set is a solid value at $21.99. It’s ideal for medium-duty residential use but best avoided if you need bagging or side-discharge performance.
