8TEN LawnRAZOR Mower Blade Set for AYP Husqvarna LT 1238 38 Inch Decks 127842 134148 581116302 532139774 (Toothed)

What It Is

The 8TEN LawnRAZOR Mower Blade Set is a toothed (mulching-style) replacement blade set designed for 38-inch cutting decks on AYP (American Yard Products) and Husqvarna LT 1238 lawn tractors. It’s built for mulching grass clippings into fine particles for natural lawn fertilization.

Fitment & Compatibility

Before buying, verify your deck size is exactly 38 inches (not 42 or 46). This set replaces OEM part numbers 127842, 134148, 581116302, and 532139774. It fits Husqvarna LT 1238 and many AYP-branded tractors (like Craftsman, Poulan, and Weed Eater) with similar 38-inch decks. Measure your existing blade’s length (should be ~20 inches), center hole diameter (typically 7/16-inch or 5/8-inch), and offset. Check that your spindle pattern matches a two-blade, offset design—these are not universal for all 38-inch decks.

Key Things to Know

• Quality: 8TEN blades are aftermarket but heat-treated and coated for rust resistance; they match OEM strength for residential use.
• Installation: Easy for DIYers—requires a socket wrench and possibly a blade removal tool. Torque bolts to 70-90 ft-lbs. Always disconnect spark plug first.
• Gotcha: The toothed design is for mulching only—not ideal for bagging or side-discharge. If you switch modes, expect clumping or uneven cut.
• Balance: Check blade balance after installation; 8TEN blades are usually pre-balanced, but verify with a blade balancer to avoid vibration.

Should You Buy It

Buy this set if you have a Husqvarna LT 1238 or compatible AYP 38-inch deck, want an affordable mulching upgrade over standard blades, and mow frequently enough to justify the toothed design. Skip it if you primarily bag or discharge clippings, or if your deck is not exactly 38 inches.
