Traction Drive Belt
The traction belt is the primary mechanical link between the engine's output pulley and the transaxle input. Over time, heat and friction cause the belt to stretch, crack, or snap, resulting in a total loss of drive torque. If the belt has derailed or broken, the transaxle will receive no rotational energy to power the internal hydrostatic pump.

Transmission Bypass Rod
The hydrostatic transaxle features a manual bypass valve that allows the machine to be rolled without the engine running. If the rod is bent, disconnected, or stuck in the 'pushed' position, the internal hydraulic circuit remains open, preventing the build-up of pressure required to actuate the drive motor.

Hydrostatic Transaxle Assembly
The Tuff Torq T40 transaxle is a sealed unit prone to internal failure if the hydraulic oil degrades or if the pump/motor pistons lose their seal. When internal tolerances exceed limits due to heat or wear, the unit can no longer generate the flow necessary to move the wheels, particularly under load or after the oil has reached operating temperature.
