John Deere AUC16767 42 Mower Deck D100 D105 E130 L107 S120

The Verdict

The Replacement Deck That Actually Fits — No Grinding, No Swearing

If you own a John Deere D100, D105, E130, L107, or S120, you already know the factory 42" deck is the weak link. The stamped steel shell eventually cracks at the spindle mounts, the belt pulleys seize, or the whole undercarriage rusts out after a few seasons of wet grass. The AUC16767 is the genuine OEM replacement — and the 4.7-star average across 235 ratings tells you most owners found exactly what they needed.

What’s Actually in the Crate

You get the complete 42-inch deck assembly: the 10-gauge stamped steel housing, three spindles, three mandrels, pulleys, and the belt guard. It arrives ready to bolt on — no assembly required beyond attaching it to your tractor’s lift linkage.

Here’s the critical detail most aftermarket listings get wrong: the AUC16767 is specific to the 42" Edge XT deck used on these five models. The bolt pattern, spindle spacing, and belt routing match factory specs exactly. As one verified buyer put it: “Bolted right up to my D105. All holes lined up perfectly, didn’t need to modify anything.” That’s the difference between an OEM part and a universal deck that requires shims and prayer.

Real-World Performance and Durability

The deck shell is 10-gauge steel with a powder-coated finish. That’s thicker than the 14-gauge steel on most aftermarket decks selling for half the price. It handles rock strikes and the occasional hidden sprinkler head without denting. The spindles are pre-greased and sealed — owners report 200+ hours of mowing before any bearing noise.

Cut quality matches factory. The three-blade design with the standard 1/2-inch blades gives you a clean, even cut at moderate ground speed. It’s not a mulching deck out of the box (you’ll need the separate mulch plug kit if that matters), but bagging and side-discharge performance are identical to what your tractor shipped with.

Where It Falls Short

Three honest tradeoffs. First, the deck does not include the drive belt or the blade engagement cable. If yours snapped or stretched, that’s another $40–60 and a trip to the dealer or a parts order. Second, it’s heavy — roughly 85 pounds. You’ll want a second set of hands or a floor jack to position it under the tractor. Most garages have a jack, but it’s worth planning for.

Third, the price. Genuine John Deere parts carry a premium, and this deck is no exception. You can find no-name decks for $150–200 less. But those often have thinner steel, misaligned holes, and no warranty support. For a part that takes two hours to swap, the OEM fit guarantee is worth real money.

Who Should Buy This — and Who Shouldn’t

Buy it if: Your current deck is cracked, rusted through, or the spindle mounts are wallowed out. Also buy it if you want a direct bolt-on with zero fabrication skills — this is the closest thing to a foolproof replacement.

Skip it if: You only need a new belt or a spindle, not the whole deck. Also skip it if you have a different model than the five listed — the mounting geometry won’t match, and you’ll be modifying a $400+ part.

FAQ: What Shoppers Actually Ask

Q: Will this fit my John Deere S240? A: No. The S240 uses a different 42" deck with a distinct mounting system. This deck fits D100, D105, E130, L107, and S120 only. Double-check your model number before ordering.

Q: Does it come with blades? A: No, the deck ships without blades. You’ll reuse your existing blades or buy three new 42-inch replacements. The spindles, pulleys, and mandrels are included and pre-installed.

Q: How long does the swap take? A: Plan on 2–3 hours for a first-timer. You’ll need a socket set, a floor jack, and a second person to help lift the deck into position. The belt routing matches factory diagrams, so follow those and you’re set.

The Verdict

Rating: 4.6/5 — Buy it if you want a genuine OEM replacement that bolts on without modification and lasts years. The fit is exact, the steel is thicker than aftermarket alternatives, and the 4.7-star owner consensus backs up the quality. Skip it if your deck is still repairable with a $30 weld patch, or if budget is the priority and you’re willing to gamble on a thinner aftermarket deck. For most owners with a cracked or rusted factory deck, this is the smart, no-regrets purchase. Just budget for the belt and blades if you need them.
