What It Is

This is a 2-pack of toothed mulching blades designed to replace stock blades on 38-inch cutting decks, primarily for Husqvarna and AYP (American Yard Products) lawn tractors. The toothed edge shreds grass clippings finer for better mulching and nutrient recycling.

Fitment & Compatibility

Deck size: Only fits 38-inch decks. Measure your deck width before buying—do not assume.

OEM cross-reference: Replaces Husqvarna/AYP part numbers 127842, 134148, 581116302, and 532139774. Check your current blade’s part number or your mower’s manual.

Tractor models: Fits Husqvarna LT1238, LT1538, LT19538, LTH1438, LTH1538, LTH18538, LTH2038R. Also compatible with many AYP/Craftsman/Poulan Pro tractors using a 38-inch deck with the same blade pattern.

Measurements: Each blade is approximately 18.5 inches long, 2.25 inches wide, with a 1-inch center hole and a 0.625-inch (5/8”) offset. Verify your spindle bolt pattern matches (usually a single center bolt).

Aftermarket vs OEM: These are aftermarket blades, not Husqvarna OEM. Quality is generally good, but tolerances can vary slightly.

Key Things to Know

• Installation difficulty: Easy. Requires a socket wrench (usually 13/16” or 5/8” socket) and a block of wood to jam the blade. Always disconnect the spark plug first.
• Mulching performance: The toothed edge produces finer clippings than standard blades, reducing bagging frequency. Not ideal for side-discharge or bagging—use only for mulching.
• Balance check: Aftermarket blades sometimes need balancing. Use a blade balancer or hang on a nail to check. Unbalanced blades cause vibration and bearing wear.
• Sharpness: Blades come sharp but may need touching up after the first few cuts. Resharpen when you see ragged grass tips.

Should You Buy It

Buy if you have a Husqvarna or AYP 38-inch tractor and want better mulching than stock blades provide. It’s a budget-friendly upgrade for fine clippings and less bagging. Skip if you need OEM exactness or if your deck is not 38 inches.
