感帯を設けてなる移動農機の４輪駆動切換装置。 A drive gear that is driven from the drive shaft of the running system that drives the rear wheels is rotatably installed on the front drive shaft, and a sleeve that connects and connects the ball clutch interposed between the drive gear and the front drive shaft is connected via a fork. The switching lever is provided so as to be slidable in the axial direction in conjunction with a switching lever connected to the clutch, and is energized by a toggle spring that switches the switching lever between the engaged state and the disengaged state of the clutch. This four-wheel drive switching device for a mobile agricultural machine is provided with a dead zone that does not act on the ball until the force reaches a specified value.
