8TEN LawnRAZOR Mower Blade Set for AYP Husqvarna Poulan LT 120 38 inch Deck 134148 139774 532134148 532139774 (Mulching)

What It Is

This 8TEN LawnRAZOR mulching blade set is designed for 38-inch cutting decks on AYP, Husqvarna, and Poulan Pro tractors. It replaces OEM part numbers 134148, 139774, 532134148, and 532139774, and is intended for mulching grass clippings into fine particles that decompose quickly.

Fitment & Compatibility

Before buying, confirm your deck is exactly 38 inches wide. These blades fit many Husqvarna and Poulan Pro models (e.g., LT 120, GT 48DXLS, PB 20H46) but also fit AYP (American Yard Products) units. Measure your current blade length (should be 18.5 inches), center hole diameter (usually 1 inch), and offset (about 3/4 inch). Check that your spindle pattern matches—these use a 5-point star center hole. Do not assume all 38-inch decks use the same blade; verify your OEM numbers match 134148 or 139774.

Key Things to Know

• Quality: These are stamped steel blades with a painted finish. They are not as thick or durable as OEM or high-end aftermarket blades, but they cut well for residential use.
• Installation: Easy—just remove the center bolt, swap blades, and torque to 70-90 ft-lbs. No special tools needed beyond a socket and torque wrench. Use thread locker if your spindles are worn.
• Balance: Each blade is individually balanced, but always check with a blade balancer after installation. Unbalanced blades cause vibration and damage spindles.
• Mulching vs. Side Discharge: These are mulching blades only. If you need to bag or side-discharge, you’ll need a different blade set (e.g., 8TEN’s “Hi-Lift” or OEM equivalents).

Should You Buy It

Buy this set if you have a 38-inch AYP/Husqvarna/Poulan tractor, want a mulching blade, and need a budget-friendly replacement that works reliably for residential mowing. Skip it if you’re a heavy commercial user, require OEM thickness, or need a blade for bagging or side discharge.
