    • An interlock circuit for a working vehicle having a vehicle body, a working implement attached to the vehicle body, a clutch mechanism for connecting and disconnecting power to the working implement, and a shifting device for determining a traveling direction of the vehicle body. The interlock circuit has a check function to check a backward operational run in which the vehicle body travels backward with the clutch mechanism engaged, and a release function to permit a backward operational run by canceling the check function. The check function checks the backward operational run based on a signal indicating an on/off state of the clutch mechanism and a signal indicating a traveling direction of the vehicle body determined by the shifting device. The release function maintains the check function off continuously by operating a release switch when the clutch mechanism is engaged, and the signal indicating a traveling direction of the vehicle body indicates forward or neutral.
    • 一种用于具有车体的作业车辆的联锁电路,安装在车体上的作业工具,用于连接和断开对工作工具的动力的离合器机构,以及用于确定车身行驶方向的换档装置。 互锁电路具有检查功能,用于检查车体在离合器机构接合时向后行进的后退操作行程,以及通过取消检查功能来允许后退操作行驶的释放功能。 检查功能基于指示离合器机构的开/关状态的信号和指示由换档装置确定的车身行驶方向的信号来检查向后运行。 当离合器机构接合时,释放功能通过操作释放开关来保持检查功能,并且指示车身行进方向的信号指示向前或中立。

    • A mower with a grass catcher (10) for collecting grass clippings transmitted from a mower unit. The grass catcher has an inlet opening (12) in a front position thereof, and an outlet opening (13) and an openable lid (14) in a rear position. The grass catcher (10) is connected to the rear end of a vehicle body to be supported in a suspended state by a grass catcher support unit (100). The support unit includes mounting posts (9) attached to the rear end of the vehicle body and extending upward, and a support link mechanism (20) for interconnecting upper regions of the mounting posts and lower rearward regions of the grass catcher, and for switching the grass catcher between a grass clippings collecting posture with the inlet opening directed forwardly of the vehicle body, and a raised dumping posture with the outlet opening directed downward. The support link mechanism performs a switching process for switching the grass catcher from the grass clippings collecting posture to the raised dumping posture. The switching process includes a translating process for translating the grass catcher obliquely rearward and upward while maintaining the grass catcher substantially parallel to the grass clippings collecting posture, and a rotating process for rotating the grass catcher until the outlet opening is directed downward.
    • 具有捕草器(10)的割草机,用于收集从割草机单元传送的草屑。 抓地器在其前部具有入口开口(12),在后方具有出口开口(13)和可打开的盖子(14)。 草捕集器(10)通过抓地器支撑单元(100)连接到待停车状态的车身后端。 支撑单元包括安装在车身后端并向上延伸的安装柱(9),以及支撑连杆机构(20),用于互连安装柱的上部区域和草地捕捉器的下部后部区域,并用于切换 在草剪收集姿势与前方向前方的入口开口之间的草捕捉器以及朝向下方的出口开口的升高倾倒姿态。 支撑连杆机构执行切换处理,以将草捕集器从草地收集姿势切换到升高的倾倒姿势。 切换处理包括:使草地捕捉器基本上平行于草屑收集姿势的方式向上方倾斜地平移草地捕捉器的转移处理,以及用于使捕捉器旋转直到出口开口朝下的旋转处理。
