PURPOSE: To automatically bury an induction guide for an unmanned lawn mower or the like by installing a plurality of guide rollers by which the induction guide wound on a rotary drum is guided in a ditch.
CONSTITUTION: A support 74 is erected and installed on a cart 73 which is provided with a plurality of wheels 72 for an apparatus, and a rotary drum 75 is supported at its upper end part so as to be freely rotatable. In addition, a long wirelike ferromagnetic substance 38 is wound on the rotary drum 75. A cutter device 77 which excavates a ditch and a guide body 78 which guides the ferromagnetic substance 38 are attached to the cart 73, and a plurality of guide rollers 79 which guide the ferromagnetic substance 38 are supported by the guide body 78 so as to be freely rotatable. Then, when the cart 73 is moved, a ditch in a prescribed depth is excavated in the ground by means of the cutter device 77, the ferromagnetic substance 38 is guided in the ditch by the guide rollers 79, and the ferromagnetic substance 38 is laid inside the ditch. As a result, an induction guide such as the ferromagnetic substance, a permanent magnet or the like can be buried continuously or intermittently and with good efficiency.
