摘要： A reel-type cutting unit including a reel blade for cutting grass in cooperation with a fixed blade. The reel blade is rotatable about a horizontal axis extending transversely of a vehicle body, to move from front to rear relative to the fixed blade with respect to a forward traveling direction of the vehicle body. The cutting unit has a main case surrounding the reel blade to define a space for carrying grass clippings in a rotating direction of the reel blade to a top level of the reel blade. A guide member is connected to the main case for receiving the grass clippings carried to the top level. The guide member defines a grass receiving space having a grass discharge opening. The grass discharge opening is connected to a grass catcher through a duct.

摘要： A walking operator type lawn mower having stepless transmissions allocated to right and left rear wheels for changing speed of engine drive and outputting the drive to the right and left rear wheels, respectively, whereby the right and left rear wheels may be driven at different speeds. Right and left control members operable by a speed control lever frictionally fixable to a selected position are interlocked to change speed arms through springs, respectively. The change speed arms are pivotable, following operation of the shift levers, for controlling change speed rates of the stepless transmissions. The change speed arms are also operable by a pair of right and left auxiliary levers to move toward a backward drive position regardless of speed setting position of the speed control lever. A constant speed straight cruising run is obtained by retaining the speed control lever in a selected position to operate the change speed arms of the right and left transmissions substantially the same amount. In this state, one of the right and left auxiliary levers may be operated to shift the corresponding change speed arm from the selected speed position to a different speed position, e.g. to a lower speed position or to a backward drive position, thereby realizing a desired turning mode.
摘要翻译：一种步行操作型割草机，其具有分配给右后轮和左后轮的无级变速器，用于分别改变发动机驱动速度并将驱动器输出到左右后轮，由此可以以不同的速度驱动左右后轮。通过可摩擦地固定到选定位置的速度控制杆可操作的左右控制部件互锁，以分别通过弹簧改变速度臂。在变速杆的操作之后，变速臂可枢转，用于控制无级变速器的变速速度。无论速度控制杆的速度设定位置如何，变速臂也可由一对左右辅助杆操作，朝向后方驱动位置移动。通过将速度控制杆保持在选定位置来操作右侧和左侧变速器的变速臂基本上相同的量来获得恒定速度的直线巡航行程。在这种状态下，可以操作右辅助杆和左辅助杆中的一个，以将相应的变速臂从所选择的速度位置移动到不同的速度位置，例如，到较低速度位置或向后驱动位置，从而实现期望的转向模式。

摘要： A lawn mower controllable by a walking operator and having two control levers each for controlling a brake and a propelling clutch. Each control lever is pivotable to a "run" position to engage the clutch and render the brake inoperative, a "neutral" position to disengage the clutch and render the brake inoperative, and a "stop" position to disengage the clutch and operate the brake. Each control lever is constantly urged to the "stop" position by a spring. The lawn mower further includes a locking lever for maintaining the control levers in the respective "neutral" positions and "stop" positions. The lawn mower is driven by an engine to engage in a grass cutting operation with the control levers maintained in the "run" positions by the urging springs. The operator may push the mower to engage in a grass cutting operation with the control levers maintained in the "neutral" positions by the locking lever. When the control levers are locked to the "stop" positions by the locking lever, the lawn mower is stopped to allow the operator to engage in a different operation.
摘要翻译：割草机由步行操作者控制，并具有两个用于控制制动器和推进离合器的控制杆。每个控制杆可枢转到“行驶”位置以接合离合器并使制动不起作用，“中立”位置使离合器脱离并使制动不起作用，并且“停止”位置使离合器脱离并操作制动器。每个控制杆通过弹簧不断地被推动到“停止”位置。割草机还包括锁定杆，用于将控制杆保持在相应的“中立”位置和“停止”位置。割草机由发动机驱动，进行切割操作，控制杆通过推压弹簧保持在“运行”位置。操作者可以通过锁定杆将控制杆保持在“中立”位置来推动割草机进行切割操作。当控制杆通过锁定杆锁定到“停止”位置时，割草机被停止以允许操作者进行不同的操作。
