Abstract:
The motorized cutter with wheels (10) comprises a motorized cutter (20) and a carriage (30). The motorized cutter (20) is equipped with an engine (24), a blade (22) rotatably driven by the engine (24), and a light-emitting unit (50) that generates laser light (52) in the same plane as the plane of rotation of the blade (22). A roadbed (90) is then cut along a line (X) drawn on the roadbed (90) by operating the motorized cutter with wheels (10) so that the line (X) is irradiated with the laser light (52). It is possible to remove the motorized cutter (20) from the carriage (30) together with the light-emitting unit (50).
