摘要： An electric working machine having an electric motor and batteries for providing power to the motor is provided. Power for charging the batteries is provided to the working machine through a connector. A key member is provided which comprises a key body having one end for insertion into and removal from a switch, and an operation portion which is integrally or removably provided at the other end of the key body extending sideways from the key body. The connector is positioned to the side of the switch at a location where it is covered by the operating portion of the key member at a turned position of the key member when the switch is in a first state, such that the connection of the connector with an external power source is made impossible. Such arrangement ensures that a simple structure having a substantially reduced number of parts is used, to supply the electric power to the electric motor and it is impossible to charge the batteries when the switch is in one state, and it is impossible to supply the electric power to the electric motor and it is possible to charge the batteries when the switch is in another state. The switch can be switched from one state to the other state by a simple operation.

摘要： In an electric lawn mower, a cutter housing includes a support plate portion for mounting an electric motor. The electric motor is disposed at a substantially central portion of the cutter housing and is connected directly to a cutter. A scroll portion is bulged from an outer edge of the support plate portion on either the left or right side of the electric motor and is sloped up rearwards. The scroll portion is formed into such a shape that it widens as it becomes closer to a discharge port at a rear of the cutter housing. Batteries are mounted on the support plate portion in an arrangement such that one of the batteries extends along an inner side of the scroll portion. The electric motor is sandwiched between front ends of the batteries. Thus, the lateral weight balance of the cutter housing is substantially uniform to enhance the travelability. Furthermore, the cutter housing is made compact.
摘要翻译：在电动割草机中，切割器壳体包括用于安装电动机的支撑板部分。电动机设置在切割器壳体的大致中心部分并且直接连接到切割器。涡卷部分从电动机的左侧或右侧的支撑板部分的外边缘凸出并向后倾斜。涡旋部分形成为随着其更靠近切割器壳体的后部处的排出口而变宽的形状。电池以这样的布置方式安装在支撑板部分上，使得电池中的一个沿着涡旋部分的内侧延伸。电动机夹在电池的前端之间。因此，切割器壳体的横向重量平衡基本上是均匀的，以增强行驶性能。此外，切割器壳体紧凑。

摘要： A cutter housing of an electric lawn mower of a walking type is inclined such that the cutter housing rises in a rearward direction. A battery is mounted to the upper face of a rear portion of the cutter housing. A discharge port for discharging cut grass into a grass bag is formed on a lower face of the rear portion of the cutter housing. An opening area of the discharge port is sufficiently maintained by the rearward rising inclination of the cutter housing. The battery is set to take a forward inclining orientation and the height of the mower body can be held to a low height. Since the battery is arranged above a rear wheel, the weight of the battery is supported by the rear wheels and the load on the front wheels is reduced so that the running direction of the electric lawn mower can be easily changed.
摘要翻译：行走型电动草坪割草机的切割器壳体倾斜，使得切割器壳体沿向后方向上升。电池被安装到刀具壳体的后部的上表面。在切割器壳体的后部的下表面上形成用于将切草放入草袋的排出口。通过切割器壳体的向后升高的倾斜来充分保持排出口的开口面积。电池设置为朝前倾斜方向，割草机主体的高度可以保持在较低的高度。由于电池配置在后轮上方，电池的重量由后轮支撑，并且前轮上的负载减小，使得电动割草机的行驶方向可以容易地改变。

摘要： A lawn mower has a machine body, a grass bag detachably attached to the machine body for collecting therein grass clippings, a driving power source mounted on the machine body, a cutter blade driven by the driving power source for rotation to cut grass, and a cutter housing covering the cutter blade. The cutter blade has air lifting sections disposed at opposite end portions thereof for producing carrier air during rotation of the cutter blade. The cutter housing has a grass clipping delivery passage for directing grass clippings to the grass bag with the carrier air produced by the air lifting sections of the cutter blade, and an exhaust air return passage for returning only the carrier air, as exhaust air, from the grass bag to the cutter housing. The grass clipping delivery passage extends in a front-and-rear direction of the cutter housing. The exhaust air return passage is disposed adjacent to and extends substantially perpendicular to the grass clipping delivery passage. The exhaust air return passage has an exhaust air inlet disposed in a rear upper surface portion of the cutter housing and an exhaust air outlet facing a rear lower end of the cutter housing.

摘要： A cutter blade for lawn mowers having an airlift curved from a cutting edge formed on a rotationally leading edge toward a rotationally trailing edge. The trailing edge of the airlift is shaped in a waveform comprising a plurality of protrusions and a plurality of depressions. The protrusion closest to an outer end where the centrifugal force is greatest during the rotation of the cutter blade, is greatest in width so as to improve the discharging capability of grass clippings. The depressions limit negative pressure generated rotationally behind the airlift. A plurality of vent holes formed in the airlift is arranged radially in lines.

摘要： A lawn mower has a power source for rotationally driving an output shaft. A housing has an interior space having a generally spiral-shaped portion. A cutting blade is disposed in the interior space of the housing and is connected to the output shaft for rotation therewith to cut grass while the spiral-shaped portion of the interior space generates a swirling airflow allowing the cut grass to swirl within the interior space. An enclosure is connected to the housing and has a grass discharge passage having an inlet opening disposed in communication with the interior space of the housing for discharging grass cut by the cutting blade and swirling within the interior space of the housing. A guiding member is disposed in the interior space of the housing for gradually changing a direction of the swirling airflow and the swirling cut grass and for guiding the swirling airflow and the swirling cut grass toward the grass discharge passage of the enclosure.

摘要： A lawn mower comprises a power source for rotatably driving an output shaft, a housing having an interior space having a generally spiral-shaped portion, and a cutting blade disposed in the interior space of the housing and connected to the output shaft for rotation therewith to cut grass. The rotating cutting blade coacts with the spiral-shaped portion of the interior space to generate a swirling air flow that causes the cut grass to swirl within the interior space. A grass discharge passage communicates with the interior space of the housing and discharges therethrough grass cut by the cutting blade and swirling within the interior space of the housing. A pivotal shutter is pivoted about a generally vertical axis by manual operation of a control member to open and close the grass discharge passage. The pivotal shutter comprises a pivotal shaft and a unitary shutter member mounted on the pivotal shaft to undergo pivotal movement therewith for opening and closing the grass discharge passage.
