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。

摘要： A safety system for a lawn mower having an engine, a propelling transmission line for transmitting drive from the engine to drive wheels, and a PTO transmission line for transmitting drive from the engine to a grass cutting unit. An engine start is allowed when the propelling transmission line is inoperative. The engine is stopped when the propelling transmission line is operative and a driver is in a non-driving state. A steering section includes an arch-like steering handle, and an auxiliary handle having a shape substantially corresponding to the steering handle and pivotable from an upper position projecting above the steering handle and a lower position depressed below the steering handle. The driver is determined to be in the driving state when the auxiliary handle is in an intermediate position adjacent the steering handle.

摘要： A dual tension clutch comprising a drive pulley, a driven pulley, and a transmission belt wound around the drive and driven pulleys. Opposite runs of the transmission belt are pressed inwardly by two spring-loaded tension pulleys supported by tension arms pivoted to each other. A triangular frame, as guided by a fixed pin, acts on the tension arms to spread the tension pulleys apart to relax the transmission belt. In the declutching state so established, the tension pulleys are opposed across and equidistant to a line extending through centers of the drive and driven pulleys.

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 walking operator type lawn mower comprising a steering handle extending rearwardly thereof, a cutting blade clutch for making and breaking drive transmission to a cutting blade, and a clutch lever pivotable between a clutch engaging position adjacent the steering handle and a declutching position away from the steering handle. A manually operable interlocking member and a control device are provided between the clutch lever and the cutting blade clutch. The control device is constantly urged to a position to disengage the clutch. The interlocking member is switchable between a position to interlock the clutch lever and the control device and a position to release the two components from each other, and is constantly urged to the release position. The cutting blade clutch is engaged only when the interlocking member is maintained in the interlocking position and the clutch lever is moved to the clutch engaging position.
