What This Belt Does

This belt transfers engine power to the transaxle drive system. A worn or stretched belt can cause:

• Loss of ground speed

• Slipping under load

• Inconsistent drive response

Replacing with the correct OEM belt restores proper performance and longevity.

Why Buy OEM?

OEM belts are engineered specifically for:

• Correct pulley engagement

• Proper belt tension

• Heat resistance under commercial load

Aftermarket belts may fit loosely, wear faster, or cause driveline issues.
