Lawn Mower Tractor Traction Transmission Drive V Belt Fits John Deere GX20006 UC30568 LA110 LA115 LA120 LA125 LA130

What It Is

This is a replacement traction drive belt for select John Deere lawn tractors, transferring power from the engine to the transmission to drive the wheels. It’s designed for models in the 100-series lineup with 42-inch or 48-inch decks.

Fitment & Compatibility

Check these before buying:

• Fits John Deere models: LA110, LA115, LA120, LA125, LA130 (and some LA140/LA145 variants). Also replaces OEM part numbers GX20006 and UC30568.
• Deck size: Works with both 42-inch and 48-inch decks, but verify your specific model’s belt routing diagram—some 48-inch decks use a different belt.
• Measurements: This belt is 92.5 inches long, 1/2 inch wide. Measure your old belt’s length (lay it flat, measure end-to-end) to confirm.
• OEM vs aftermarket: This is an aftermarket belt, not John Deere OEM. It should fit the same pulleys, but aftermarket belts can vary slightly in material stiffness or thickness. If you have a tight pulley system, check clearance.
• Quick check: Look at your tractor’s model tag (under seat or on frame) and cross-reference with the OEM part number GX20006 or UC30568.

Key Things to Know

• Quality is acceptable for the price – most users report it lasts 1-2 seasons with normal use. Not as durable as OEM Kevlar-reinforced belts, but fine for residential mowing.
• Installation is moderate difficulty – you’ll need to remove the deck and possibly the mule drive pulley to route the belt. A belt tensioner tool or a 1/2-inch ratchet helps.
• Common gotcha: The belt may be slightly stiffer than OEM, making it harder to slip over the engine pulley. Loosen the tensioner bolt fully before forcing it.
• Warranty: This belt typically has a 30-day return window. If it fails within a month, you can exchange it.

Should You Buy It

If you need a budget-friendly replacement for a John Deere 100-series lawn tractor and don’t mind a slightly stiffer belt that may wear a bit faster than OEM, this is a solid pick. It’s best for light-to-moderate residential use on flat terrain. Avoid it for heavy commercial mowing or if you need maximum longevity—go OEM in that case.
