  • the vibration generator 82 operates when the rotor clutch 13 is in an on state to vibrate the plate 81 up and down, and stops operating when the rotor clutch 13 is in an off state to stop the vibration of the plate 81.
  • the plate 81 and the vibration generating device 72 are connected to the planting unit 4 via, for example, a link mechanism (not shown), and move up and down together with the planting unit 4. According to the leveling device 80 for leveling by hitting the farm scene with the plate 81, it is possible to suppress the winding of mud.
  • the arrangement location of the plate 81 is not limited between the rear wheel and the float 14 as in the present embodiment, and may be provided, for example, between the front wheel and the rear wheel or in front of the front wheel. Moreover, you may provide the plate 81 in multiple places.
  • the present invention can be used for a rice transplanter including a planting clutch for turning on / off power to a planting unit and a rotor clutch for turning on / off power to a leveling device.
