Abstract
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.
