1 PC SHLPDFM Mower Drive Belt Lawn Tractor Transmission Drive Belt GX20006 Fits for John Deere L105 L107 L108 L110 L111 L118 L20 D110 D120 D125 D130 D140 D150

What It Is

This is an aftermarket drive belt (GX20006 replacement) for several John Deere lawn tractors, transferring power from the engine pulley to the transmission. It’s designed for 100- and 200-series models with 42-inch or 48-inch decks and a manual or hydrostatic transmission.

Fitment & Compatibility

Before buying, confirm your tractor model and deck size. This belt fits John Deere L105, L107, L108, L110, L111, L118, L120, D110, D125, D130, D140, and D150. It replaces OEM part GX20006 (also known as GX20006A). Measure your old belt’s length and width (typically 1/2 inch wide, ~92.5 inches long for most listed models). Double-check your deck size—some D-series with 54-inch decks use a different belt. Aftermarket belts may vary slightly in length or tension; verify routing diagram for your model.

Key Things to Know

• Quality vs. OEM: At $8.50, this is a budget belt. Expect shorter lifespan than a John Deere OEM belt (typically $25–$40). May need retensioning after a few hours.
• Installation difficulty: Moderate. You’ll need to remove the deck or at least the mower belt shield. Routing is straightforward but be sure to release tension from the idler pulley first.
• Common gotchas: Belt may be slightly too long or too short for some models—compare length to your old belt. Check pulley condition; worn pulleys can cause premature belt wear.
• Reviews: Only 3 reviews at 3.8/5—limited feedback. No warranty info listed; buy with caution if you need reliability.

Should You Buy It

Buy this belt if you need a cheap, temporary fix for a mower that sees light use (small lawn, occasional mowing). Skip it if you mow frequently, have a large property, or want long-term durability—spend more on an OEM or premium aftermarket belt for better fit and longevity.
