Summary:PROBLEM TO BE SOLVED: To enable users to change the rotation of a cutting blade and the speed of a traveling machine body during mowing by making the rotational speed of an electric motor adjustable.SOLUTION: The mower has an electric motor M which transmits power to a rotary shaft of a cutting blade 3C and a traveling machine body F which travels by power branched from the rotary shaft, and a control lever H attached to the traveling machine body F includes a rotational speed adjustment part 53 which adjusts the target rotational speed of the electric motor M. A control device 50 which controls the rotational speed of the electric motor M controls the electric motor M by weak magnetic field control when the actual rotational speed of the electric motor M is in the range of the target rotational speed that the rotational speed adjustment part 53 sets. 【課題】電動モータの回転数を調整可能とすることにより草刈り時の刈刃の回転や走行機体の速度の変更を行うことができるようにする。【解決手段】刈刃３Ｃの回転軸に動力を伝達する電動モータＭと、回転軸から分岐された動力により走行する走行機体Ｆとを備え、走行機体Ｆに取り付けられた操縦ハンドルＨに、電動モータＭの目標回転数を調整する回転数調整部５３を備えている。電動モータＭの回転数を制御する制御装置５０は、電動モータＭの実回転数が、回転数調整部５３で設定する目標回転数の範囲内であるときは、弱め磁界制御によって電動モータＭを制御する。【選択図】図１
