Abstract: 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.

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.

Abstract: A blower for transporting grass clippings from a grass cutting unit to a grass catcher of a lawn mower comprises a housing with a protective liner extending over peripheral inside walls thereof. The liner includes a lining material formed of an elastic resin, and a core formed of a plastically deformable metal and embedded in the lining material.
