PROBLEM TO BE SOLVED: To solve the problem that tilling efficiency is liable to decrease, and a continuous operation time shortens to make workability easily decrease when a change in tilling load due to rotation of tilling claws is large during tilling work using an electric motor.SOLUTION: An electric tiller has a tilling rotor 3 arranged behind a travel wheel 2 of a vehicle body 1 and drives the travel wheel 2 by a variable-speed motor 4 whose speed is variable, and the tilling rotor 3 by a fixed-speed motor. A tilling transmission cylinder 11 pivotally mounted with a tilling association shaft 10 for associating a fixed-speed motor 5 and a rotor shaft 9 with each other is disposed to be inclined relative to the vehicle body 1.COPYRIGHT: (C)2012,JPO&INPIT【課題】 電動モータによる耕耘作業にあっては、この耕耘爪の回転による耕耘負荷の変化が大きいと、耕耘効率が低下し易く、連続運転時間が減少し、作業性の低下を招き易い。【解決手段】 車体1の走行車輪2の後側に耕耘ロータ3を配置し、この走行車輪2を変速操作可能の可変速モータ4で駆動し、耕耘ロータ3を固定速モータで駆動する電動耕耘機。また、固定速モータ5とロータ軸9の間を連動する耕耘連動軸10を軸装した耕耘伝動筒11とを、車体1に対して前後に各々傾斜させて配置する。【選択図】 図1
