PROBLEM TO BE SOLVED: To suppress battery consumption in a two-motor type electric farm working vehicle including separately an electric motor for power that generates traveling power and working power, and an electric motor for a hydraulic pump that drives the hydraulic pump.SOLUTION: An electric riding rice transplanter includes a planting working machine 3 liftably connected to a traveling machine body 1 a working machine lifting hydraulic cylinder 4 lifting the planting working machine 3 the hydraulic pump 15 supplying pressure oil to the working machine lifting hydraulic cylinder 4 the electric motor 5B for the hydraulic pump that drives the hydraulic pump 15 the electric motor 5A for power that generates traveling power and working power and a motor control device 23 controlling driving of the electric motor 5A for power and the electric motor 5B for the hydraulic pump. The motor control device 23 detects the lifting operation fixed state of the planting working machine 3, and stops driving of the electric motor 5B for the hydraulic pump when the planting working machine 3 is in the lifting operation fixed state.COPYRIGHT: (C)2013,JPO&INPIT【課題】走行動力及び作業動力を発生させる動力用電動モータと、油圧ポンプを駆動させる油圧ポンプ用電動モータとをそれぞれ別々に備える2モータ方式の電動農作業車において、バッテリ消費を抑える。【解決手段】走行機体1に昇降自在に連結される植付作業機3と、該植付作業機3を昇降させる作業機昇降用油圧シリンダ4と、該作業機昇降用油圧シリンダ4に圧油を供給する油圧ポンプ15と、該油圧ポンプ15を駆動させる油圧ポンプ用電動モータ5Bと、走行動力及び作業動力を発生させる動力用電動モータ5Aと、動力用電動モータ5A及び油圧ポンプ用電動モータ5Bの駆動を制御するモータ制御装置23と、を備える電動乗用田植機において、モータ制御装置23は、植付作業機3の昇降動作固定状態を検出すると共に、植付作業機3が昇降動作固定状態のときは、油圧ポンプ用電動モータ5Bの駆動を休止させる。【選択図】図12
