gx20571 gx21833 265-238 Compatible with John Deere 155c l130 l120 la140 d140 Belt, Replacement Stens 265-238 (1/2" X141 1/2")

What It Is

This is a replacement drive belt (1/2" x 141 1/2") designed for John Deere lawn tractors, specifically models 155c, L130, L120, LA140, and D140. It connects the engine pulley to the deck or transmission, enabling blade engagement or drive function.

Fitment & Compatibility

Before buying, verify your John Deere model’s deck size (e.g., 42", 48") and year, as belt routing varies. Cross-reference OEM part numbers: GX20571, GX21833, and 265-238. Measure your old belt’s length (141.5 inches) and width (0.5 inches) to confirm match. This belt is aftermarket (Stens 265-238 equivalent), so it fits the listed models but may not fit newer revisions or non-Deere decks. Check your mower’s belt diagram online to ensure routing aligns.

Key Things to Know

• Quality: Aftermarket belts like this often match OEM specs but may have slightly different rubber compounds; expect similar durability but not identical lifespan.
• Installation: Easy for DIYers with basic tools—requires removing deck or belt covers and using a tensioner tool. No special expertise needed.
• Common Gotcha: Belt length is critical; a 1/2" variance can cause slippage or poor engagement. Measure your old belt or consult your model’s manual.
• Reviews: 4.4/5 from 9 reviews suggests good value for the price, but limited feedback means verify fitment with your specific model.

Should You Buy It

If you own a compatible John Deere tractor (155c, L130, L120, LA140, D140) and need a low-cost, functional replacement for a worn or broken belt, this is a solid budget option. It’s best for DIYers comfortable with basic mower maintenance and who prioritize price over OEM-grade longevity. Avoid if you need a belt for a non-listed model or demand exact OEM specifications.
