Abstract
A system for controlling operation of a ground treatment machine includes a hand-held device that wirelessly communicates with the ground treatment machine. The system includes a radio frequency and an infrared frequency wireless communications that are established between the hand-held device and the ground treatment machine. Instructions associated with operation of the machine are communicated to the machine from the hand-held device via the radio frequency communications. A status of the infrared wireless communication is utilized to assess the proximity of the ground working machine relative to the operator and the operating environment such that operation of the machine in accordance with the operational instructions can be interrupted if necessary.
