    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: 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 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 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.
