Abstract
PURPOSE:To prevent malfunction and danger in forgetfulness of change operation of control mode, by detecting a leveling state of a leveling plate by a checking sensor at the rear part of the leveling plate and carrying out tilling depth control by a tilling depth sensor only in a case suitable for control of tilling depth. CONSTITUTION:Control of tilling depth by a tilling depth sensor 5 is carried out only when a checking sensor 6 which is positioned at the rear end of a leveling plate 2 and slides on the surface of leveled soil is sliding on approximately the same face as the leveled face by the leveling plate 2. When raking operation is carried out or a tilling device 3 is raised on the soil face and is in an untilling attitude, control of tilling depth by the tilling depth sensor 5 is stopped.
