Ground Drive Belt
The ground drive belt is the primary medium for transferring rotational energy from the engine to the transaxle. Over time, heat-induced rubber degradation or mechanical friction causes the belt to snap or stretch beyond the tensioning capacity of the idler pulley, resulting in a total loss of drive power to the hydrostatic unit.

Axle Square Key
This key provides the mechanical interference fit between the transaxle output shaft and the rear wheel hub. If the external E-ring/retaining clip fails, the wheel can shift outward on the axle, allowing the key to fall out. Once removed, the axle spins freely inside the hub, providing zero torque to the ground even if the transmission is fully engaged.

Engine Woodruff Key
The Woodruff key locks the drive pulley to the engine's vertical crankshaft. If the mower experiences a sudden mechanical shock or high-torque event, this key can shear. This results in the crankshaft spinning inside the pulley without rotating the drive belt, effectively severing the power supply to the entire drive system.
