Abstract
An apparatus fitted with a power take-off (PTO) drive connectable to ancillary equipment and means for actuating and deactuating the PTO drive is disclosed wherein an interlock system includes sensor means for sensing whether the PTO drive is operative and producing an output signal representative thereof, timer means coupled to the actuating and deactuating means and initiated when said means is operated, and means responsive to the sensor output signal and coupled to timer means and operable to produce a deactuating signal if the sensor output signal is of a predetermined nature when the timer times out. The deactuating signal is applied to a selected component of the apparatus to deactuate that component.
