Kimsion GX20072 Deck Belt (1/2'' x 104'') for John Deere 42'' Deck Lawn Mowers D100, D105, D125, D130, E100, E130, L100, L110, L118, LA115 Replacement John Deere 42 inch Deck Belt GY20570

What It Is

The Kimsion GX20072 is an aftermarket replacement deck belt (1/2″ wide, 104″ long) designed for 42-inch cutting decks on select John Deere lawn tractors. It drives the mower blades from the engine pulley.

Fitment & Compatibility

• Deck size must be exactly 42″. Measure your existing belt or check your deck’s model number.
• Fits these John Deere models: D100, D105, D125, D130, E100, E130, L100, L110, L118, LA115. Also compatible with OEM part numbers GY20570 and GX20072.
• Aftermarket vs. OEM: This is an aftermarket belt—not John Deere branded. It’s cheaper but may have slightly different rubber compound or stiffness.
• Check belt length and width: Belt is 1/2″ wide (not 3/8″ or 5/8″) and 104″ long. Measure your old belt to confirm before buying—some 42″ decks use different lengths.

Key Things to Know

• Quality varies: Some users report shorter lifespan than OEM belts, especially under heavy use or in wet grass. Expect 1–2 seasons of typical residential mowing.
• Installation is moderate: You’ll need to remove the deck or at least the belt guard. No special tools, but follow the deck belt routing diagram for your model (available online).
• Check for correct routing: The belt must wrap around all pulleys correctly—wrong routing causes poor blade engagement or belt slip.
• Price vs. OEM: At ~$16, it’s roughly half the cost of a John Deere belt. Good for budget-minded homeowners who mow a standard lawn.

Should You Buy It

Buy this Kimsion belt if you need a low-cost replacement for a 42″ John Deere deck and you’re comfortable with moderate DIY installation. It’s fine for residential use and light mowing, but if you mow frequently, in tough conditions, or want maximum durability, consider spending more on an OEM John Deere belt.
