1. A material reduction machine comprising:

  • an engine;

    a material reduction tool;

    a clutch configured and arranged to engage and disengage the material reduction tool with the engine; and

    a control unit configured to control when the clutch disengages the material reduction tool based, at least in part, on a control signal received from a sensor that detects the presence of an operator;

    wherein the control unit is configured to decelerate the material reduction tool by maintaining the clutch engaged with the engine during an engine speed reduction period, wherein the engine speed reduction period is sufficiently short as to enable the engine to recover without requiring manually restarting.
