GX24154 1/2" x 98"Lawn Mower Deck Drive Belt Fits for John Deere D105 D140 E100 X105 X106 M118760 M41668 07200116 120 300 Series Tractors

What It Is

This GX24154 belt is a 1/2-inch wide, 98-inch long replacement drive belt for the mower deck on select John Deere lawn tractors. It transfers power from the engine pulley to the deck spindles, making the blades spin. It fits models like the D105, D140, E100, X105, X106, and the 120/300 Series tractors.

Fitment & Compatibility

Before buying, verify your tractor’s model number (e.g., D105, X106) and deck size. This belt is designed for 42-inch and 48-inch decks on the listed models. Cross-reference your OEM part numbers: John Deere M118760, M41668, or 07200116. If your original belt has a different length (e.g., 96.5 inches) or width (e.g., 5/8-inch), this belt will not fit. Measure your old belt’s length end-to-end (not around pulleys) and width—GX24154 is exactly 1/2" wide x 98" long. Aftermarket belts like this may vary slightly from OEM in material stiffness, but length and width must match.

Key Things to Know

• Quality: Made from standard rubber/polyester; adequate for residential use. Not heavy-duty commercial grade, but holds up well for typical lawn care.
• Installation: Moderate difficulty. You’ll need to remove the deck, route the belt around pulleys and tensioner, then reinstall. Check your deck’s belt diagram (often under the deck lid) or manual.
• Common gotcha: The belt may feel tight at first—ensure the tensioner arm moves freely. If the belt squeals or slips, double-check routing or tensioner spring condition.
• Longevity: Expect 2-3 seasons with regular mowing on flat terrain. Replace if you see cracks, fraying, or glazing.

Should You Buy It

Buy this if you need an affordable, direct-fit replacement for a John Deere D105, D140, E100, X105, X106, or 120/300 series with a 42" or 48" deck and your OEM part is M118760, M41668, or 07200116. It’s a solid budget option for residential mowing, but skip it if you have a heavy commercial workload or need a wider or longer belt.
