Abstract

PURPOSE:To correct a much waving boundary to a less waving state by constituting a deviation detecting means so that it can be freely switched to extend or narrow a dead zone range where the absence of deviation is decided. CONSTITUTION:A deviation detecting means a which detects the deviation in the breadthwise direction of a vehicle body from a boundary L between a work field B which is not subjected to treatment yet and a work field C subjected to treatment is so constituted that it can be freely switched to extend or narrow said dead zone range. In the normal state where the boundary L is less waved, the deviation detecting means A is switched to narrow the dead zone range and the vehicle body is allowed to precisely follow up the boundary L. If the boundary L is much waved, the deviation detecting means A is switched to extend the dead zone range and the vehicle body is allowed to roughly follow up the boundary L. Thus, the waving boundary L is corrected to a less waving state.
