GX20006 Traction Drive Belt 1/2" x 89" Fit for John Deere D100 D110 D120 D125 D130 D140 S100 S120 Series, LA115 LA135 LA145, L110 L130 48" Lawn Tractor Mower UC30568

What It Is

This is a traction drive belt (1/2" wide x 89" long) that transfers power from the engine to the transaxle on select John Deere lawn tractors. It’s designed for models with 48" decks or smaller, used in the D100, S100, and LA/L series.

Fitment & Compatibility

Before buying, confirm three things:

• Model & series – Fits John Deere D100, D110, D120, D125, D130, D140, S100, S120, LA115, LA135, LA145, L110, L130 (48" deck models).
• Dimensions – Must be exactly 1/2" wide x 89" long. Measure your old belt if possible—slight variations can cause slipping or poor engagement.
• OEM part cross-reference – Replaces John Deere UC30568 and GX20006. Aftermarket belt, not OEM. Verify your mower’s original belt number matches.

Do not assume fit based on model alone – some models have multiple deck sizes; only 48" deck versions are compatible.

Key Things to Know

• Quality – Good value for the price. Users report it lasts a full season with normal use, but not as durable as OEM for heavy commercial mowing.
• Installation – Moderate difficulty. You’ll need to remove the mower deck and possibly the belt guard. A belt tensioner tool helps.
• Common gotcha – If your old belt is frayed or cracked, check pulleys for damage or misalignment before installing the new belt.
• Alternative – If you have a 54" or 60" deck, this belt will not fit. Verify deck size on the model tag.

Should You Buy It

If you own one of the listed John Deere models with a 48" deck and want a reliable, budget-friendly replacement for routine maintenance, this belt is a solid choice. It’s not built for heavy commercial use, but for residential mowing, it performs well and saves money over OEM.
