ABSTRACT:
An emergency shutoff system for power machinery includes a control device housing a transmitter circuit, a receiver circuit, and a processor. A wireless device is carried by a user and configured to transmit information to the control device to cause the processor to shut down operation of the power machinery. The control device is configured to transmit a distress signal to a third party located remote from the power machinery, and provide an indication to attract attention of others. Transmission of the distress signal is initiated after receiving the control signals to shut down the power machinery. Selective operation of a single emergency switch provided on the wireless device is configured to cause the control device to operate in a plurality of different modes including disabling operation of the power machinery and preventing a third party from inadvertently initiating operation of the power machinery from a remote location.
