Youxmoto 127842 38'' Toothed Mulching Mower Blades for Craftsman Poulan AYP 134148 138497 532134148 532138497 for Husqvarna LT1238 LT1538 LT19538 LTH1438 LTH1538 LTH18538 LTH2038R, 2 Pack

What It Is

This is a 2-pack of 38-inch toothed mulching blades designed to replace OEM parts on select Craftsman, Poulan, AYP, and Husqvarna lawn tractors, specifically for mulching grass clippings into fine particles that decompose quickly.

Fitment & Compatibility

Before buying, measure your existing blade length (must be exactly 38 inches end-to-end) and check the center hole size (typically 1 inch) and offset (usually 1 inch). These blades replace OEM numbers 134148, 138497, 532134148, and 532138497. Compatible with Husqvarna models LT1238, LT1538, LT19538, LTH1438, LTH1538, LTH18538, and LTH2038R, plus many Craftsman and Poulan 38-inch deck tractors. Verify your deck width is 38 inches and that your spindle pattern matches. Not for zero-turn or push mowers.

Key Things to Know

• Mulching vs. regular blades: These have a curved, toothed edge that recirculates clippings for finer cut – not ideal for bagging or side-discharge.
• Installation: Requires a torque wrench (set to 70-90 ft-lbs) and a blade removal tool. Always disconnect the spark plug and use a blade balancer after installation.
• Durability: Aftermarket steel may be softer than OEM – check for bending or dulling after heavy use. Replace in pairs for balanced cutting.
• Common gotcha: These are designed for 38-inch decks only. Using on a 42-inch deck will leave uncut strips.

Should You Buy It

If you have a 38-inch deck Craftsman, Poulan, or Husqvarna tractor and want finer mulching without buying OEM, this is a cost-effective option. However, if you frequently bag or side-discharge, stick with standard lift blades.
