Patent number: 11884141Abstract: A protection mechanism for a working vehicle includes a roof above an operator's seat and including a cutout extending along a top-bottom direction, and an electric device at least partially located in the cutout. The cutout has a dimension along a vehicle-body-width direction that is uniform or substantially uniform along a front-to-rear direction or increases in the front-to-rear direction. The cutout has a thickness along the top-bottom direction that decreases in the front-to-rear direction. The roof include, in an upper surface thereof, a first groove located on an opposite side of the cutout from the electric device and extending in a direction away from the cutout.Type: GrantFiled: December 10, 2021Date of Patent: January 30, 2024Assignee: KUBOTA CORPORATIONInventors: Satoru Horai, Takuya Nishikubo, Taiki Furuki, Megumi Miyamoto

Publication number: 20220276656Abstract: A work vehicle includes a vehicle body including wheels, a controller to cause the vehicle body to perform automatic travel along a travel route set in advance, a driver seat mounted on the vehicle body, a driver seat protective body provided around the driver seat, first obstacle detectors provided at side portions of the driver seat protective body, and capable of detecting an obstacle; and second obstacle detectors provided at positions differing from positions of the first obstacle detectors in a front-back direction, and capable of detecting an obstacle. At a time of start of the automatic travel, the controller is configured or programmed to put each first obstacle detector in a detection state of detecting an obstacle, and, during automatic travel after the start of the automatic travel, the controller is configured or programmed to put each first obstacle detector in a non-detection state of not detecting the obstacle.Type: ApplicationFiled: May 17, 2022Publication date: September 1, 2022Inventors: Takuya NISHIKUBO, Fumiya YOSHIMURA, Koichi SHINTANI
