GY20495 One New Seat Fits John Deere Fits JD Riding Mower LA100 L100 L105 L108 L110 L111 X110 102 105 125

What It Is

The GY20495 is an aftermarket replacement seat designed for a wide range of John Deere riding mowers, primarily the LA100, L100, L105, L108, L110, L111, X110, 102, 105, and 125 series. It replaces the OEM part number GY20495 and is intended for residential lawn tractors and garden tractors needing a direct-fit seat swap.

Fitment & Compatibility

Before buying, verify your model number—this seat fits specific series, not all John Deere riders. Check the original seat’s mounting hole pattern: the GY20495 uses a 4-bolt pattern with 10-11 inch center-to-center spacing (both front-to-back and side-to-side). Measure your existing seat’s bolt holes to confirm. It does not fit zero-turn mowers or older (pre-2000) models like the LX or GT series. The seat pan is 16.5 inches wide and 13.5 inches deep—measure your deck clearance if you have a tight cab or ROPS. It includes a seat switch (safety interlock) connector—ensure your mower’s wiring harness matches the 2-pin flat plug.

Key Things to Buy

• Quality: This is a budget aftermarket seat—foam is firm but less dense than OEM. Expect ~3-5 years of residential use before sagging or cracking.
• Installation: Easy, 15-30 minutes. Use a 1/2-inch socket/wrench. No drilling required if your bolt pattern matches. The seat switch connector may need slight trimming if the wire is too long.
• Common Gotcha: The seat pan is unpainted steel—rust can start if stored outdoors. Apply a coat of rust-resistant paint or use a seat cover. The slide-adjustment lever can be stiff initially; spray with silicone lubricant.
• Comfort: No armrests or lumbar support. Fine for 1-hour mowing sessions; longer rides may feel hard.

Should You Buy It

If your OEM seat is cracked, torn, or the foam is flattened, and you want a simple, bolt-on replacement without paying $150+ for a genuine John Deere seat, this is a solid value. It’s best for budget-conscious homeowners who mow 1-2 acres weekly and don’t need premium comfort or heavy-duty durability. Skip it if you have an older model with odd bolt spacing or need a seat with armrests or high-back support.
