Caltric Transmission Belt Compatible with John Deere L105 L107 L108 L110 L111 L118 L120 L130 LA110 LA115 LA120 LA125 LA130 LA135 LA140 LA145 LA150 LA155 LA165 LA175 GX20006

What It Is

This is an aftermarket transmission drive belt designed for select John Deere lawn tractors and zero-turn mowers. It transfers power from the engine to the transmission, enabling forward and reverse movement.

Fitment & Compatibility

Before buying, confirm your exact John Deere model number (e.g., L105, L110, LA130, LA175). This belt replaces OEM part GX20006. Measure your existing belt length and width—this belt is 7/8-inch wide and 92.5 inches long (approximate). Check your deck size: it fits 42-inch, 48-inch, and 54-inch decks on listed models, but not all decks use the same belt. Verify your transmission type (Tuff Torq K46, K57, or similar) to ensure the belt matches the pulley system. Caltric is an aftermarket brand, not OEM, so expect slight differences in material or fit tolerance.

Key Things to Know

• Quality: Caltric belts are budget-friendly but may wear faster than OEM belts under heavy use or high-torque conditions.
• Installation: Moderate difficulty—requires removing the mower deck and belt guards. Have a diagram or manual handy for belt routing.
• Common Gotcha: The belt may be slightly tighter or looser than OEM; adjust tension via the idler pulley. Check pulley alignment before finalizing.
• Durability: Rated for residential use; not ideal for commercial mowing or rough terrain.

Should You Buy It

If you need a low-cost replacement for a residential John Deere lawn tractor with one of the listed models, this belt works fine for light-to-medium mowing. Avoid it if you mow frequently on steep slopes or need maximum longevity—invest in an OEM or premium aftermarket belt instead.
