Ground Drive Belt
The YTA24V48 utilizes a General Transmissions RS800 CVT system which is frequently misidentified as a hydrostatic drive. This system relies on a variable-ratio pulley (variator) that is highly sensitive to the physical condition and tension of the ground drive belt. Over time, the belt undergoes thermal hardening and stretching, leading to a loss of frictional engagement under high-torque scenarios like incline navigation; replacing the belt restores the required mechanical grip to actuate the variator mechanism effectively.

RS800 Transaxle Assembly
If the external belt is intact and tensioned, the internal variator mechanism or the internal drive belt of the RS800 transaxle has likely failed. These units are often considered non-serviceable for consumer-level repair as internal components like the plastic variator arms or the internal CVT belt are not widely sold as individual SKUs. A full assembly replacement is the only reliable forensic resolution if the internal drive-train has lost the ability to convert engine RPM to wheel torque.
