Parallel travel work system

A parallel travel work system comprising an autonomous travel work vehicle, an accompanying travel work vehicle accompanying the autonomous travel work vehicle, and a remote controller for communicating with the autonomous travel work vehicle, wherein:

• the remote controller is configured to create a first preset travel path along which the autonomous travel work vehicle autonomously travels and a second preset travel path along which the accompanying travel work vehicle travels;
• the autonomous travel work vehicle is equipped with:
• a position calculating means for calculating a position of a body of the autonomous travel work vehicle using a satellite positioning system,
• a steering actuator configured to operate a steering device,
• a transceiver configured to communicate with the remote controller, and
• a control device configured to control the position calculating means, the steering actuator and the transceiver, the control device carrying out autonomous travelling of the autonomous travel work vehicle along the first preset travel path acquired from the remote controller via the transceiver;
• and
• wherein:
• the remote controller is provided with a display configured to display the first preset travel path and the second preset travel path;
• and
• the display recognizably displays, in the displayed first and second preset travel paths, unworked sections and worked sections of the preset travel paths.
