Claims

[Scope of utility model registration request]

In a walk-behind agricultural machine comprising a vehicle body supported by wheels, and an engine that drives the wheels via a traveling transmission, and a control handle, between an output shaft from the engine and an input shaft to the traveling transmission. A gear case is rotatably inserted in the power transmission path of An intermediate bevel gear meshing with both the gear and the second bevel gear is provided, the first bevel gear is interlocked with the output shaft, the second bevel gear is interlocked with the input shaft, and the gear case is interlocked with the first bevel gear. A forward/reverse switching device for a walking agricultural working machine, characterized in that the device is configured to be able to freely switch between a state in which it rotates integrally with the first bevel gear or the second bevel gear and a state in which it cannot rotate.
