All golf carts (much like cars) have a clutch, which is a part of the drivetrain that helps the put the power of the motor
through to the wheels/ground. Golf cart clutches are also known as a Continuously Variable Transmission (or CVT).
This transmission is comprised of two different clutches connected together by a golf cart drive belt. The two clutches
are the:

1. Golf Cart Drive Clutch (Primary)
2. Golf Cart Driven Clutch (Secondary)

The drive (primary) clutch connects to the engine crankshaft while the driven (secondary) clutch is bolted onto the cart’s
input shaft. 

The Drive Clutch & Driven Clutch work in tandem to smoothly propel your golf cart forward when power is applied via the
accelerator pedal. Conversely, these same clutches help with smooth deceleration when the cart is in motion and the
accelerator is released (even if the brake is not yet depressed).
