PROBLEM TO BE SOLVED: To provide an electric riding mower which can maintain a fixed mowing height even if there is unevenness.SOLUTION: The electric riding mower includes: a mower blade which rotates to mow grass substantially bowl-shaped mower decks 15 which cover the mower blade from above and sides a mower motor 20 disposed on the mower decks 15 and attached to a rotating axis of the mower blade a main frame 18 which suspends the mower decks 15 on the right and left sides in such a way as rotatable in the vertical direction and which is extended in the direction of advancement hydraulic cylinders 42A and 42B which suspend the mower decks 15 between the cylinders and the main frame 18 for rotating the mower decks 15 in the vertical direction and an acceleration sensor 150 for detecting unevenness on a traveling surface. The respective mower decks 15 are independently rotated in the vertical direction along the main frame 18 according to the unevenness on the traveling surface detected by the acceleration sensor.COPYRIGHT: (C)2012,JPO&INPIT【課題】起伏があっても刈高さを一定に保持可能な電動の乗用草刈機を提供する。【解決手段】回転して草を刈るモアブレードと、モアブレードを上方および側方から覆う略深皿状のモアデッキ15と、モアデッキ15上に配置されるとともに、モアブレードの回転軸に取り付けられたモアモータ20と、モアデッキ15を左右両側にそれぞれ上下回動可能に懸架し、かつ、進行方向に延設されるメインフレーム18と、モアデッキ15をメインフレーム18との間に懸架するとともに、モアデッキ15を上下に回動させるための油圧シリンダ42A,42Bと、走行面の起伏を検出する加速度センサ150とを備え、加速度センサが検出した走行面の起伏に従って、それぞれのモアデッキ15が独立してメインフレーム18に沿って上下に回動する。【選択図】図6
