Canamax GX20006 UC30568 Drive Belt - Aramid Cord 1/2 x 89 inches - for John Deere D110 D140 L120 L110 LA135 LA145 L130 D130 D170 LA115 D160 L111 L108 125 D125 115 L118 LA120 LA130 LA175 Lawn Mower

What It Is

The Canamax GX20006 UC30568 is an aftermarket drive belt (1/2 x 89 inches) built with aramid cord reinforcement. It transfers power from the engine to the mower deck blades on select John Deere lawn tractors, primarily 100- and 200-series models.

Fitment & Compatibility

Check your model number – this belt fits John Deere D110, D140, L120, L110, LA135, LA145, L130, D130, D170, LA115, D160, L111, L108, 125, D125, 115, L118, LA120, LA130, and LA175. It does not fit all decks on these models – confirm your deck size is 42", 48", or 54" (common but not universal).
Measure your old belt – this is 1/2 inch wide by 89 inches long. If your original measures differently (e.g., 90" or 1/2" x 88"), this belt won’t route correctly.
OEM cross-reference – replaces John Deere GX20006 and UC30568. Aftermarket, not OEM – same specs, lower price.
Verify pulley condition – worn or bent pulleys can cause premature belt failure regardless of brand.

Key Things to Know

• Aramid cord vs. standard – aramid (like Kevlar) resists stretching and heat better than rubber-only belts, but it can be slightly stiffer during initial installation.
• Installation difficulty – moderate. You’ll need to remove the deck and route the belt around pulleys and tensioners. A diagram from your manual helps.
• Common gotcha – the 89" length is tight on some decks (e.g., 54" cut). If your old belt was 90", this may require forcing the tensioner – not recommended.
• Noise – a few users report a brief squeak during break-in (10–20 minutes). If it persists, check pulley alignment.

Should You Buy It

If you need a budget-friendly replacement for a John Deere 100/200-series tractor with a 42–54 inch deck and your old belt measures 1/2 x 89 inches, this is a solid choice. It’s not as durable as a premium OEM belt, but for the price and aramid construction, it’s a good value for light-to-medium mowing duty. Skip it if you mow heavy grass daily or want a longer warranty.
