Drive Belt
The drive belt is the primary mechanical link between the engine's drive pulley and the hydrostatic transaxles. Over time, heat cycles and torsional stress cause elastomer fatigue or internal cord snapping, resulting in a total loss of torque transfer to the rear wheels. If the belt snaps or slips off the pulleys, the mower will lose all propulsion regardless of engine speed.

Drive Idler Pulley
The idler pulley maintains the necessary tension on the drive belt to ensure friction-based power transfer. Bearing failure within the pulley or a fatigue failure of the tensioner spring prevents the belt from gripping the transaxle pulleys, leading to a failure to move under load. A seized bearing can also create enough friction to melt or snap the drive belt.

Hydro-Gear EZT Transaxle
Internal failure of the hydrostatic pump or motor within the EZT unit results in a loss of hydraulic pressure. This is often caused by oil degradation or the shearing of internal components like the cylinder block or piston assembly. If the unit cannot generate sufficient fluid pressure to rotate the axle shafts, the machine will remain stationary despite linkage actuation.
