Abstract: A steering platform includes a main floor supported by a body framework extending longitudinally of a vehicle, and footrests extending from the main floor laterally outwardly of the framework. A brake pedal and a shift pedal are arranged on the footrests. The framework in a steering platform region supports cross shafts extending transversely through the framework. These shafts include a brake control shaft for pivotally supporting a brake lever, and a shaft for driving a raising and lowering link mechanism of a grass cutting unit. The cross shafts include outward extensions for supporting the footrests through brackets, respectively.

Abstract: 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.
