GY20496 AUC11476 Deluxe High Back Seat for John Deere Riding Mower Lawn Tractor Models G110 L100 L105 L107 L110 L118 L120 L130 135 145 A-GY20496

What It Is

The GY20496 AUC11476 Deluxe High Back Seat is an aftermarket replacement seat designed for select John Deere riding mowers and lawn tractors. It provides a padded, high-back design for improved comfort during extended mowing sessions, intended as a direct swap for worn or damaged OEM seats.

Fitment & Compatibility

Before buying, verify your mower model and seat measurements. This seat fits John Deere models G110, L100, L105, L107, L110, L118, L120, L130, 135, and 145. It replaces OEM part numbers GY20496 and AUC11476. Check that your mounting hole pattern matches—most of these models use a four-bolt pattern with 7.5–8 inch spacing (center-to-center). Measure your existing seat’s bolt spacing and overall width (approx. 17–18 inches wide) to confirm fit. Also ensure your mower has a standard flat seat pan; some models with suspension brackets may need adapters. Aftermarket, so no John Deere warranty applies.

Key Things to Know

• Quality vs. OEM: Users report the foam is firmer and the vinyl cover less durable than original John Deere seats. It may show wear faster under heavy use or sun exposure.
• Installation: Typically straightforward—remove four bolts, swap seats, and reinstall. No wiring or special tools needed. Allow 15–30 minutes.
• Common Gotcha: The seat may sit slightly higher or lower than OEM due to foam density differences. Check clearance with the steering wheel and fenders before final tightening.
• Hardware: Includes mounting bolts and washers, but some users note they’re low-grade. Consider reusing your original bolts if they’re in good condition.

Should You Buy It

This seat is a budget-friendly fix for a worn or broken seat on a John Deere L- or G-series lawn tractor. It’s fine for light to moderate residential use if you’re not picky about exact OEM feel or long-term durability. Skip it if you need heavy-duty commercial toughness or a perfect factory match—spend more on an OEM seat instead.
