PROBLEM TO BE SOLVED: To provide an electric riding mower highly stable in traveling and effectively making mower decks follow unevenness on a traveling surface.SOLUTION: The electric riding mower includes: a mower blade the mower decks 15 which cover the mower blade from above and sides a mower motor 20 which is disposed on the mower decks 15 a main frame 18 which suspends the mower decks 15 on both right and left sides in such a way as rotatable in the vertical direction and which is extended in the direction of direct advancement and gauge wheels 23 which are attached to the mower decks 15 for detecting unevenness on the traveling surface. The respective mower decks 15 are independently rotated in the vertical direction according to the unevenness on the traveling surface detected by the gauge wheels 23. The electric riding mower also includes: a subordinate frame 55 between the mower decks 15 and the main frame 18 for lifting the mower decks 15 and coil springs 42A and 42B for energizing the mower decks 15 to rotate downward. One end of the coil spring 42A or 42B is attached to the vicinity of a side of the mower motor 20, and the other end is attached to the subordinate frame 55.COPYRIGHT: (C)2012,JPO&INPIT【課題】走行安定性がよく、効果的にモアデッキを走行面の起伏に追随させることが可能な電動乗用草刈機を提供する。【解決手段】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モアデッキ15と、モアデッキ15上に配置されるモアモータ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、直進方向に延設されるメインフレーム18と、モアデッキ15に取り付けられ、走行面の起伏を検出するゲージホイール23とを備え、ゲージホイール23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が独立して上下に回動する。そして、モアデッキ15とメインフレーム18との間にモアデッキ15を昇降するためのサブフレーム55を備えるとともに、モアデッキ15を下方に回動するように付勢するコイルバネ42A,42Bを備え、コイルバネ42A,42Bの一端をモアモータ20の側部近傍に取り付けるとともに他端をサブフレーム55に取り付ける。【選択図】図6
