Ground Drive Belt
The ground drive belt is the single component responsible for transferring mechanical energy from the engine crankshaft pulley to both transaxle input shafts. Over time, heat and friction cause aramid cord fatigue, leading to a snap or significant elongation. If the belt fails, the hydrostatic pumps cannot generate the fluid pressure required for wheel motor actuation.

Drive Idler Pulley
The idler pulley maintains the necessary friction between the drive belt and the transaxle sheaves. A seized internal bearing or a worn-out pulley surface will cause the belt to slip or derail entirely. This interruption in the kinetic chain prevents the transaxles from reaching the required RPMs to move the machine forward.

Idler Tension Spring
This spring provides constant tension to the idler arm assembly; a fracture or significant loss of spring rate (fatigue) results in a slack belt. Without sufficient tension, the drive belt cannot grip the engine or transaxle pulleys, causing a total loss of drive capability despite the engine running at high RPM.
