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： 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： 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.
