Abstract
A material reduction machine including an engine, a material reduction tool, a drivetrain, and a control system. The drivetrain is between the engine and the material reduction tool, and includes a coupling and a power transfer element, the coupling having an engaged state and a disengaged state. When engaged, the coupling enables power transfer through the power transfer element and when disengaged, the coupling inhibits power transfer through the power transfer element. The control system includes a sensor to detect a speed of the engine or the material reduction tool, a drivetrain protection system to protect the power transfer element by disengaging the coupling, and a controller to enable the drivetrain protection system based on a first signal from the sensor indicating the speed is at or above a first threshold, and to disengage the coupling based on a second signal indicating the speed is below a second threshold.
