Lawn Mower Deck Blades for John Deere AM137327 AM141032 M154061 LT160 LT180 X300 Series 42 inch Cut Deck 2 Pack

What It Is

This is a 2-pack of aftermarket 42-inch deck blades designed to replace OEM John Deere part numbers AM137327, AM141032, and M154061. They’re intended for use on John Deere LT160, LT180, and X300 series tractors with 42-inch cutting decks.

Fitment & Compatibility

Before buying, verify your mower’s deck size is exactly 42 inches (measured blade tip to tip). These blades fit John Deere models LT160, LT180, and X300 series (including X300, X304, X310, X320, X324, X340, X360) with the 42-inch Edge or stamped deck. They are aftermarket replacements, not OEM, so confirm your OEM part numbers match: AM137327, AM141032, or M154061. Measure your current blade length (should be ~21 inches), center hole diameter (usually 1 inch or 7/8 inch), and thickness (typically 0.25 inch). These blades are not compatible with 48-inch or 54-inch decks.

Key Things to Know

• Quality: Aftermarket blades are often made from hardened steel but may be slightly thinner or lighter than OEM. Check for balanced edges to reduce vibration.
• Installation: Easy swap with a socket wrench and torque to 70-90 ft-lbs. Use thread locker on bolts if not pre-applied. Always lift the deck safely and block it.
• Gotcha: Some aftermarket blades have different hole shapes (oval vs. round) or offset angles. Compare visually with your old blade before mounting. If your old blade has a “wing” or “sail” shape, these may be straight-edge—fine for mulching but less lift for bagging.
• Performance: Expect similar cut quality to OEM for standard grass, but they may dull faster on sandy or rocky terrain. Sharpen after 10-15 hours of use.

Should You Buy It

If you need a budget-friendly, direct replacement for a John Deere 42-inch deck and your OEM part numbers match, this 2-pack offers solid value for the price. It’s best for residential mowing on typical lawns, not heavy commercial use or rocky conditions. For strict OEM fit or frequent bagging, consider paying more for genuine John Deere blades.
