Autonomous traveling work apparatus

An autonomous traveling work apparatus comprising:

• a traveling wheel provided on a vehicle body;
• a control unit configured to control the traveling wheel;
• and
• a work unit configured to recognize a boundary between vegetation to be mown and a portion other than the vegetation to be mown and to mow an edge of vegetation along the boundary, wherein
• the work unit includes a support section and a cutting section,
• the cutting section includes:
• a passive rotary cutter that is rotatably supported on one of a left side or a right side of the vehicle body, has a rotation axis passing through a rotation center of the passive rotary cutter and oriented in a direction intersecting a front-rear direction of the vehicle body, and includes a plurality of blade parts on an outer peripheral portion of the passive rotary cutter;
• a fixed cutter that is disposed on the one of the left side or the right side of the vehicle body, is supported by the support section, is disposed outwardly adjacent to the passive rotary cutter in a vehicle width direction, and is configured not to rotate;
• and
• a driving rotary cutter that is supported on the one of the left side or the right side of the vehicle body, has a rotation axis passing through a rotation center of the driving rotary cutter and oriented in the direction intersecting the front-rear direction, is configured to rotate via a drive device, and is disposed inwardly adjacent to the passive rotary cutter in the vehicle width direction, and
• wherein the passive rotary cutter passively rotates in response to the passive rotary cutter receiving a ground reaction force as the autonomous traveling work apparatus travels,
• the fixed cutter and each of the blade parts form a shearing region above a ground, and the vegetation is pinched and sheared between the fixed cutter and the blade part in the shearing region, and
• the driving rotary cutter cuts the vegetation above the shearing region.
