PROBLEM TO BE SOLVED: To configure a paddy field work machine so that the battery is not likely to interfere when the paddy field work machine is placed on a bed of a truck or stored in a narrow barn or the like. A mount 39 capable of supporting a battery 40 is provided. The work position C1 in which the mounting base 39 extends from the outer peripheral portion of the floor 28 to the outside of the machine body in plan view and the mounting base 39 overlaps the outer peripheral portion of the floor 28 in plan view and is positioned inside the machine body from the work position C1. A battery support portion 35 that supports the mounting base 39 in a relocatable manner is provided at the storage position C2.
