John Deere AUC16767 42" Mower Deck D100 D105 E130 L107 S120 S240 X106 X127 X145

What It Is

This is a genuine OEM 42-inch stamped steel mower deck from John Deere, designed to replace worn or damaged decks on select D100, E100, and X100 series lawn tractors. It’s a complete assembled deck with spindles, pulleys, and blade mounting hardware—ready to bolt on.

Fitment & Compatibility

Before buying, verify your tractor’s model and serial number. This deck fits John Deere models D100, D105, E130, L107, S120, S240, X106, X127, and X145—but only those originally equipped with a 42-inch deck. Measure your current deck width (cutting width, not overall width) to confirm it’s 42 inches. The deck uses a two-belt drive system and a specific mounting bracket pattern; check that your tractor’s frame and mule drive match. This is an OEM John Deere part (AUC16767), not an aftermarket copy—fitment is guaranteed for listed models. If your tractor has a 38-inch or 48-inch deck, this will not fit.

Key Things to Know

• Quality: OEM steel construction is thicker than many aftermarket decks, reducing warping and vibration over time. Spindles are pre-greased and sealed.
• Installation: Moderate difficulty—expect 1–2 hours. You’ll need to remove the old deck, transfer the mule drive and belt, and bolt this one on. A floor jack or helper is recommended.
• Blades not included: The deck comes with spindles and pulleys but no blades. You’ll need to purchase three 42-inch blades separately (e.g., John Deere U11066 or AM137332).
• Common gotcha: The deck’s anti-scalp wheels and gauge wheels are sold separately. If your old deck had them, you’ll need to reuse or replace them.

Should You Buy It

If your current 42-inch John Deere deck is rusted through, cracked, or beyond repair, this OEM replacement is the most reliable option. It’s pricey but built to last, with exact fitment for the listed models. For budget-conscious owners, a high-quality aftermarket deck may save money, but expect compromises in steel thickness and spindle durability. This is the right choice for anyone wanting a direct, hassle-free swap.
