Patent number: 9810131Abstract: Regarding a work vehicle configured to include an engine mounted on a travelling machine body and an exhaust gas purification device arranged in an exhaust gas path of the engine, it is an object to prevent the regeneration control of the exhaust gas purification device from being executed against an operator's will. The work vehicle of the present invention includes a regeneration switch 329 configured to cause the regeneration control of an exhaust gas purification device 50 to be executed. First, when a cumulative drive time of an engine 5 has passed in a prescribed time or longer, a regeneration control request warning is displayed on a meter panel 246. Then, only when a regeneration switch 329 is manually operated by an operator after the display of the regeneration control request warning on the meter panel 246, the regeneration control of the exhaust gas purification device 50 is started.Type: GrantFiled: September 12, 2014Date of Patent: November 7, 2017Assignee: Yanmar Co., Ltd.Inventors: Akimichi Iwata, Kazuhisa Yokoyama, Yuusuke Koike

Patent number: 9731723Abstract: A working vehicle includes an engine, a pair of right and left traveling portions rotated by a power of the engine, a pair of right and left brake operation devices for respectively operating to brake the traveling portions, an engine controller which controls driving of the engine, and a control mode selection switch which can alternatively select the isochronous control and the droop control. The engine controller selects any of an isochronous control and a droop control so as to control the engine. In the case that the isochronous control is designated by the control mode selection switch, the engine is controlled according to the isochronous control when one of the right and left brake operation devices is under a non-operation state, and the engine is controlled according to the droop control when both of the right and left brake operation devices are under an operation state.Type: GrantFiled: September 27, 2016Date of Patent: August 15, 2017Assignee: Yanmar Co., Ltd.Inventors: Akimichi Iwata, Hiroshi Isobe

Patent number: 9631530Abstract: Regarding a work vehicle that includes an engine mounted on a travelling machine body and an exhaust gas purification device arranged in an exhaust gas path of the engine, it is an object to prevent the regeneration control of the exhaust gas purification device from being executed against operators' will. The work vehicle of the present invention includes a regeneration switch 329 for executing the regeneration control of an exhaust gas purification device 50, a meter panel 246 for displaying the situation of driving operations of a travelling machine body 2, and a work device 15. Then, when it is assumed that a predetermined amount or more of particulate matter in the exhaust gas purification device 50 is accumulated, the meter panel 246 notifies a regeneration control request warning and displays characters that urge stoppages of work of the work device 15 and travelling of the travelling machine body 2.Type: GrantFiled: August 29, 2014Date of Patent: April 25, 2017Assignee: Yanmar Co., Ltd.Inventors: Yuusuke Koike, Akimichi Iwata, Kazuhisa Yokoyama
