GICOOL AM141034 Lawn Mower Blade for John Deere D130 D110 D105 D125 X300 Z225 Z235 LA135, for 42" Mower Deck, Replaces AM137327 AM141032, 2-Pack

What It Is

This is a 2-pack of 42-inch lawn mower blades designed to replace OEM blades on select John Deere tractors and zero-turn mowers. They are meant for cutting grass on residential lawns and are a direct aftermarket alternative to John Deere part numbers AM137327 and AM141032.

Fitment & Compatibility

Before buying, confirm your mower deck is exactly 42 inches (measured cutting width). These blades fit John Deere models: D130, D110, D105, D125, X300, Z225, Z235, LA135, and others with a 42-inch deck. They replace OEM part numbers AM137327 and AM141032. Measure your old blade’s length (should be ~21 inches), center hole diameter (should be 7/8 inch or 22mm), and thickness (about 0.2 inches). Verify your spindle hole pattern matches—these are for 5-point star or oval center holes. Not compatible with 46-inch or 54-inch decks.

Key Things to Know

• Quality vs. OEM: These are aftermarket blades. They may be slightly thinner or less durable than genuine John Deere blades, but they’re fine for typical residential mowing on grass (avoid rocks or thick debris).
• Installation Difficulty: Easy—requires a socket wrench and possibly a blade removal tool. Always disconnect the spark plug and block the blade before loosening the bolt. Torque to 45-55 ft-lbs.
• Sharpness: Blades come sharp but may need a quick touch-up after first use if you hit anything hard. Check balance before installing—unbalanced blades cause vibration and deck damage.
• Common Gotcha: The 2-pack is often sold as “for 42-inch deck” but each blade is ~21 inches long. If your deck uses two blades (most common), this pack covers one full set. If your deck uses three blades, you’ll need a second pack.

Should You Buy It

If you own a compatible John Deere with a 42-inch deck and want a budget-friendly replacement for regular grass cutting, this is a solid choice. It’s not for heavy-duty or commercial use, but for the price and average reviews, it’s a good value for homeowners who need quick replacement without the OEM markup.
