To accurately determine whether a current position is a farm field or not.SOLUTION: An electric tractor includes: a first electric motor 41; rear wheels 12R that rotate according to drive force from the first electric motor 41; and a control device 100 controlling the first electric motor 41. The control device 100 executes farm field determination processing of determining that a current position is a farm field, if a state in which a change amount of rotational speed of the first electric motor 41 is equal to a specified value or greater continues for a prescribed period.SELECTED DRAWING: Figure 2

    【課題】現在位置が圃場であるか否かを精度よく判定する。【解決手段】電動トラクタは、第1電動モータ41と、第1電動モータ41からの駆動力により回転する後輪12Rと、第1電動モータ41を制御する制御装置100とを備えている。制御装置100は、第1電動モータ41の回転速度の変化量が規定値以上となる状態が規定期間継続した場合に現在位置が圃場であると判定する圃場判定処理を実行する。【選択図】図2
