Abstract
A forage harvester represents agricultural implements that include at least one rotating component which is driven through a drive train including a main clutch operable between engaged and disengaged conditions so as to selectively couple and disconnect an output of the implement power source with the rotatable component. A rotation alarm circuit is provided for causing a warning device or devices to be energized in the event that the operator leaves a seat, in which he sits for normal operation, for a predetermined minimum time period while the rotatable component is still rotating, as determined by a rotation sensor. The warning device will remain energized until the rotatable component spins down to a zero speed.
