    Abstract: An electric work vehicle includes a battery container provided in a traveling vehicle body and including a guiding unit, and a battery pack removably attached to the battery container and including a guided unit. A pair of rollers are provided in one of the guiding unit and the guided unit, and a pair of engaging portion to be engaged with the rollers are provided in the other of the guiding unit and the guided unit. When the battery pack is loaded or unloaded onto/from the battery container at the loading/unloading position, the rollers engage with the engaging portions, thereby functioning as pivot fulcrums for enabling the battery pack to pivot for loading and unloading.

    Abstract: A lawn mower includes a mower deck including a blade rotationally driven to cut grass and generate an air flow to feed the cut grass. A cutting chamber houses the blade. An ejection outlet is open to the cutting chamber and ejects the cut grass. A grass collection container collects the cut grass ejected from the ejection outlet. An air chamber is provided in a vicinity of the cutting chamber and receives the air flow generated by rotation of the blade through the grass collection container. A first passage connects the ejection outlet and the grass collection container. A second passage connects the grass collection container and the air chamber. The air flow supplied from the grass collection container to the air chamber through the second passage is supplied to the cutting chamber.

    Abstract: A vehicle steerable by movement of the center of gravity has an auxiliary wheel. A left drive wheel is driven by a left rotary driver. A right drive wheel is driven by a right rotary driver. A gravity center position calculator calculates a position of the center of gravity of a driver on a steering step board based on a detection signal from a load detection module detecting a load distribution of the driver. A travel controller has a first control mode controlling rotary drive of the left and right rotary drivers to achieve straight forward travel or turning. The travel controller also has a second control mode controlling the rotary drive of the left and right rotary drivers to achieve straight forward travel, turning or straight backward travel based on the position of the center of gravity. A driver input operation device can be used to select either the first or the second control mode.

    Abstract translation: 通过重心运动可转向的车辆具有辅助轮。 左驱动轮由左旋转驱动器驱动。 右驱动轮由右旋转驾驶员驱动。 重心位置计算器基于来自检测驾驶员的负载分布的负载检测模块的检测信号计算驾驶员在转向踏板上的重心位置。 行驶控制器具有控制左右旋转驾驶员的旋转驱动器的第一控制模式，以实现直行或转弯。 行驶控制器还具有控制左右旋转驾驶员的旋转驱动器的第二控制模式，以实现基于重心的位置的直线向前行驶，转弯或直线向后行驶。 驱动器输入操作装置可用于选择第一或第二控制模式。
