Abstract
An adaptive soft start system for mower blade clutch engagement includes an engine speed sensor providing engine speed inputs to a microcontroller that provides electrical power to an electromagnetic clutch for engaging an engine to at least one mower blade. The microcontroller repeatedly computes the rate of change of engine speed during mower blade clutch engagement and modulates the electrical power to the electromagnetic clutch each time the rate of change of engine speed is outside minimum or maximum thresholds.
