PROBLEM TO BE SOLVED: To provide a riding type working vehicle mounted with the control to suppress power consumption of an electrically-driven working device for performing work for a work object around a vehicle body accompanying the running of the vehicle body.SOLUTION: A riding type working vehicle includes: a vehicle body with an operation seat a drive wheel unit for supporting the vehicle body a mower unit with a rotary blade for performing reaping work for a work object around the vehicle body accompanying the running of the vehicle body a working motor for driving the rotary blade a motor control part for executing operation control of the working motor in a steady mode or in a power-saving mode whose power consumption is smaller than the steady mode and a working load evaluation part for evaluating a load of the working motor. When the load of the working motor evaluated by the working load evaluation part is a low load lower than a threshold, the motor control part operates the working motor in the power-saving mode.COPYRIGHT: (C)2015,JPO&INPIT【課題】車体の走行に伴って車体周囲の作業対象物に対する作業を行う電動式作業デバイスの電力消費を抑制する制御を実装された乗用作業車の提供。【解決手段】運転座席を備えた車体と、車体を支持する駆動車輪ユニットと、車体の走行に伴って車体周囲の作業対象物に対する刈取り作業を行う回転ブレードを有するモーアユニットと、回転ブレードを駆動するための作業用電動機と、作業用電動機を定常モード又は定常モードより消費電力が少ない省電力モードで動作制御する電動機制御部と、作業用電動機の負荷を評価する作業負荷評価部とを備え、作業負荷評価部によって評価された作業用電動機の負荷がしきい値より低い低負荷である場合に、電動機制御部は前記作業用電動機を省電力モードで動作させる。【選択図】図1
