MightyRugged GX20006 John Deere Drive Belt Replacement - Belt Length 88.9" - Heavy-Duty, Durable, Aramid Cord Drive Belt for D110, D140, L110, L111, L118, L120, LA115, LA125, LA130 Lawn Mowers & More

What It Is

The MightyRugged GX20006 is a heavy-duty replacement drive belt for select John Deere lawn tractors, designed to transfer power from the engine to the transmission. It’s built for mowing and general yard work on residential or semi-commercial machines.

Fitment & Compatibility

Before buying, confirm your mower’s model and deck size. This 88.9-inch belt fits John Deere D110, D140, L110, L111, L118, L120, LA115, LA125, and LA130 models, plus others using OEM part GX20006. Measure your old belt’s length (end-to-end, not looped) to verify. Check your deck size—typically 42" or 48" for these models. This is a direct aftermarket replacement for OEM GX20006; it’s not universal—do not assume it fits all Deere tractors. Verify your mower’s model number (stamped under the seat or on the frame) before ordering.

Key Things to Buy

• Quality: Aramid cord construction is more durable than standard rubber belts—resists stretching and heat better under heavy use.
• Installation: Moderate difficulty. You’ll likely need to remove the deck or mower hood to route the belt correctly. A belt installation diagram is helpful; check your owner’s manual or online guides.
• Gotcha: The 88.9" length is exact—too tight or too loose can cause slippage or premature wear. If your old belt measures slightly different, double-check fitment.
• Gotcha: Some users report needing to adjust belt tension after a few hours of use—tighten if you hear squealing or see slipping.

Should You Buy It

Buy this if you need a reliable, budget-friendly replacement for a worn or broken GX20006 belt on a compatible John Deere lawn tractor. It’s a solid upgrade over standard OEM belts for durability, but skip it if you’re not comfortable with a moderate DIY install or if your mower model isn’t listed above.
