John Deere Original Equipment Seat - AUC11476,1

What It Is

The John Deere Original Equipment Seat (AUC11476) is a direct replacement seat for select John Deere lawn tractors. It provides a comfortable, durable seating surface for residential mowing and light-duty yard work.

Fitment & Compatibility

Before purchasing, verify your machine’s model number. This seat fits specific John Deere models, including the LA115, LA125, LA135, LA145, LA155, and LA165, as well as the D105, D110, D125, D130, D140, D150, D155, D160, and D170. It is not a universal fit—check your tractor’s model plate (usually under the seat or on the frame) against this list. The seat measures approximately 17 inches wide by 15 inches deep. It uses a four-bolt mounting pattern with 5/16-inch bolts spaced 10.5 inches apart front-to-back and 7.5 inches side-to-side. Measure your existing seat base to confirm alignment. This is an OEM part, not an aftermarket generic, so it matches the original dimensions and mounting holes exactly for these models.

Key Things to Know

• Quality: Built with John Deere’s standard foam and vinyl cover. It’s firm but comfortable for typical residential use. Expect 3-5 years of life with normal care.
• Installation: Easy—remove four bolts, lift old seat, drop in new one, and bolt it down. No wiring or special tools required. Allow 15-20 minutes.
• Common Gotcha: The seat does not include a seat switch or mounting hardware. Reuse your existing bolts and switch if your tractor has one. If your model uses a different mounting pattern (e.g., wider spacing on older X-series), this won’t fit.
• Pricing: At $168, it’s more expensive than aftermarket options, but you get guaranteed fit and OEM foam density.

Should You Buy It

Buy this if you own one of the listed LA or D-series models and want a hassle-free, exact-fit replacement that matches the original seat’s comfort and durability. It’s ideal for homeowners who value OEM quality and don’t want to measure or modify mounting holes. Skip it if you’re on a tight budget or have an older model with a different bolt pattern—aftermarket universal seats are cheaper but require adapters.
