What It Is

This is a 1/2" x 89" drive V-belt (OEM replacement for UC30568) that transfers power from the engine to the transmission on select John Deere lawn tractors. It’s designed for 100-series tractors like the D140, D110, D130, L130, and others listed.

Fitment & Compatibility

Before buying, confirm your mower model and verify the belt length (89 inches) and width (1/2 inch). This belt fits John Deere models: D140, D110, D130, L130, L110, L120, LA135, LA145, LA115, L111, L118, D170, LA130, LA110, D125, LA120. It replaces OEM part UC30568. This is an aftermarket belt, not genuine John Deere. Check your owner’s manual for the correct belt routing diagram—incorrect routing can cause slipping or damage.

Key Things to Know

• Quality: At $14.39, this is a budget-friendly aftermarket option. It may not last as long as an OEM belt under heavy use, but reviews (4.8/5) suggest it’s reliable for typical homeowner mowing.
• Installation difficulty: Moderate. You’ll need to remove the deck and possibly the mule drive pulleys. A spring puller tool helps with tensioner springs.
• Common gotcha: Double-check belt length with a tape measure before installing—some users report slight variations in aftermarket belts. If it’s too short or long, it won’t engage properly.
• Warranty: No specific warranty mentioned; treat as a disposable wear item.

Should You Buy It

If you need a cheap, functional replacement for a John Deere 100-series tractor and don’t mind occasional belt changes, this is a solid choice. For heavy commercial use or if you want maximum durability, spend more on an OEM belt. For weekend mowing on a budget, it’s a great value.
