Abstract

PURPOSE:To improve controllability by making the changeover of speed change and of forward-backward travel possible by only operating one travel speed change lever of a transmitter of a remote control device. CONSTITUTION:A transmitter 49 is provided with a power source switch 51, an engine switch 52, a travel switch 54, a mower switch 55 to start a mower and a brake switch 56 respectively. Travel speed change levers 57, 58 turning up and down, and right and left are also provided to perform the changeover of speed change and of forward-backward travel. The transmitter 49 feeds signals issued from each of the switches 51, 52, 54, 56 and the lever 57 into a microcomputer circuit, and then transmits the signals through a FM transmitting module from an antenna 59. On the side of a working vehicle, a receiving antenna 65 provided on the side of the vehicle receives a transmitted wave, which is input through a FM receiving module into the microcomputer circuit. Various apparatus on the vehicle 2 are operated on the signals fed from the microcomputer circuit to make the unmanned travel of the vehicle possible.
