PROBLEM TO BE SOLVED: To realize a motorized tractor with high energy recovery efficiency by accurately grasping a work mode and the like.SOLUTION: A tiller 41 is attached to a tractor body to be able to elevate to a machine body 1. A rear wheel motor 10, which is connected with a battery and performs a driving output to a rear wheel output shaft 12, and a front wheel motor 11, which performs a driving output to a front wheel output shaft 25, are respectively provided. The front wheel motor 11 is configured to be switched to a power generating mode by receiving a power generation output from the front wheel output shaft 25 side. A power charger is connected with a circuit of the front wheel motor 11 and generates power to charge the battery by receiving the power generation output from the front wheel output shaft 25 side. A brake action is applied to front wheels 2 by a power generating action to prevent so called dashing which is caused by a rotation of rotary claws of the tiller 41.COPYRIGHT: (C)2013,JPO&INPIT【課題】作業状態等を的確に把握してエネルギ回収効果の高い電動トラクタを具現しようとする。【解決手段】機体1に耕耘作業機41を昇降自在に装着し、バッテリーに接続され後輪出力軸12に駆動出力する後輪用モータ10と前輪出力軸25に駆動出力する前輪用モータ11を夫々設け、前輪用モータ11を前輪出力軸25側からの発電出力を受けて発電状態に切換わる構成とする。前輪用モータ11の回路に充電器を接続し、前輪出力軸25側からの発電出力を受けて発電し前記バッテリーを充電する。発電作用により前輪2にブレーキ作用を付与し、耕耘作業機41のロータリ爪の回転による所謂ダッシングを防止する。【選択図】図3
