Traction Drive Belt
The traction drive belt is the primary mechanical link between the engine crankshaft and the hydrostatic transaxle. Over time, the EPDM material undergoes thermal degradation and elongation, leading to a loss of friction against the pulleys or an outright snap. Without this belt, the transaxle cannot receive the rotational energy required to generate hydraulic pressure for wheel rotation.

Drive Idler Pulley
The idler pulley maintains constant tension on the drive belt via a spring-loaded arm. If the internal ball bearings fail or the pulley shell deforms, the belt loses the necessary tension to grip the transaxle input pulley, resulting in a total loss of drive despite the engine running at high RPM.

Transaxle Input Pulley
The input pulley is secured to the transaxle pump shaft via a splined fit or a keyway. High-torque loads or vibration can cause the internal splines of the pulley to strip out, particularly if the retaining nut has loosened. In this state, the belt turns the pulley, but the rotational energy is not transferred to the internal hydrostatic pump.
