What It Is

The Stens 330-056 is a replacement lawn mower blade designed for John Deere X300 and LX series tractors with a 38-inch deck. It’s a sharp, durable aftermarket blade that directly replaces OEM part numbers AM100945, AM100991, AM137324, AM137326, AM141041, M153118, M154159, and M83459.

Fitment & Compatibility

Before buying, confirm your deck size is exactly 38 inches (not 42 or 48). This blade fits John Deere X300, X304, X320, X324, and LX series mowers (e.g., LX172, LX173, LX176, LX178, LX186, LX188). It requires two blades per deck—one for each spindle. Measure your existing blade’s length (should be ~17.5 inches) and center hole diameter (should be 1 inch) to verify. Stens is an aftermarket brand, so while it meets OEM specs, it’s not a John Deere original part.

Key Things to Know

• Installation is straightforward with basic tools (socket wrench and torque wrench). No special adapters needed.
• Check blade orientation—the lift wing should point upward toward the deck. Wrong side up will reduce cutting performance.
• Sharpen or replace annually depending on use. Dull blades tear grass, leading to brown tips.
• Balance before installing—unbalanced blades cause vibration, stress on spindles, and uneven cuts. Use a simple blade balancer.

Should You Buy It

If you own a John Deere X300 or LX series with a 38-inch deck and need a reliable, budget-friendly replacement, this Stens blade is a solid choice. It matches OEM specs, has strong reviews, and costs less than John Deere branded blades. Just confirm your deck size and buy two.
