Abstract
A belt drive for a work machine is disclosed. The belt drive has a drive belt that is wound around an input pulley and an out put pulley. The input pulley is rotated by a motor, and when rotated, transfers rotational motion to the output pulley by the drive belt. A controller is in communication with an input speed sensor that measures the input pulley and an output speed sensor that measures the output pulley. The controller calculates an input speed from the measurement of the input pulley, and an output speed from the measurement of the output pulley. The controller also sends a damaged belt signal to an operator control of the work machine when the output speed is lower by a predetermined threshold than the input speed.
