GX20006 Drive Belt Kevlar for John Deere D110, D130, D140, D170, L110, L111, L120, L130, LA145 Lawn Tractors, Replaces UC30568 John Deere Drive Belt - Aramid Cord, 1/2'' x 89''

What It Is

This is a Kevlar-reinforced drive belt for John Deere lawn tractors, designed to transfer power from the engine to the transmission or mower deck. It’s intended for residential mowing on models like the D110, D130, D140, D170, L110, L111, L120, L130, and LA145.

Fitment & Compatibility

Before buying, confirm your tractor model and deck size. This belt replaces OEM part UC30568 and fits John Deere models with 42-inch or 48-inch decks (check your owner’s manual). The belt measures 1/2 inch wide by 89 inches long—verify your current belt’s length and width. It’s an aftermarket replacement, not OEM, but uses aramid (Kevlar) cord for extra strength. If your tractor uses a different belt length (e.g., 88 inches or 90 inches), this won’t work.

Key Things to Know

• Material advantage: Aramid cord resists stretching and heat better than standard rubber belts, so it lasts longer under heavy use.
• Installation difficulty: Moderate. You’ll need to remove the mower deck and route the belt around pulleys and tensioners. A diagram from your tractor’s manual helps.
• Common gotcha: If your old belt snapped, check for misaligned pulleys or a seized spindle before installing the new one—otherwise, you’ll burn it out quickly.
• Noise: Some users report a slight squeak initially; it usually fades after a few minutes of run-in.

Should You Buy It

If you need a durable, budget-friendly replacement for a worn UC30568 belt on a compatible John Deere lawn tractor, this is a solid choice. It’s not OEM, but the Kevlar core offers good value for residential mowing. Avoid it if you prefer exact OEM fitment or have a model with a non-standard deck size.
