Disclosed herein is a driving cab for tractors. A hollow part is provided in a bottom plate of the driving cab, and a hollow shaft is provided in the bottom plate so as to be rotatable around the hollow part. A driver seat, an implement control device and a movement control device are fixed to the hollow shaft, so that the driver seat, the implement control device and the movement control device can be rotated along with the hollow shaft. Thereby, the implement control device and the movement control device along with the driver seat can be easily turned in a desired direction. When the tractor is required to be moved forwards or backwards, the implement control device and the movement control device along with the driver seat can face in the direction in which the tractor moves, so that the driver can easily control movement of the tractor.
