PROBLEM TO BE SOLVED: To provide a paddy field working vehicle having such a construction that: when a turning-starting position is detected by operation to the non-working state of a working apparatus by a manually operative tool and the front wheels steering operation, a work-ending position (the turning-starting position) and a work-starting position (a turning-ending position) come to a nearly same position being set apart from the levee.SOLUTION: The paddy field working vehicle works as follows: the turning-ending position E32 is shifted toward a turning-starting position E12 side along turning trajectories L1 and L2 of the machine body (refer to &theta1, E31) so that a difference is reduced between the turning-ending position E31 of the machine body based on the operation to a non-operation condition of the working apparatus 5 by manual operation device, and the turning-ending position E32 of the machine body based on the operation to a non-operaton condition of the working apparatus 5 by steering operation of a front wheel 1.COPYRIGHT: (C)2010,JPO&INPIT【課題】水田作業車において、人為操作具及び前輪の操向操作による作業装置の非作業状態への操作により旋回開始位置が検出された場合、作業終了位置(旋回開始位置)と作業開始位置(旋回終了位置)とが、畦から略同じ位置になるように構成する。【解決手段】人為操作具による作業装置5の非作業状態への操作に基づく機体の旋回終了位置E31と、前輪1の操向操作による作業装置5の非作業状態への操作に基づく機体の旋回終了位置E32との差が小さくなるように、旋回終了位置E32を機体の旋回行程L1,L2に沿って旋回開始位置E12側に移動させる(θ1,E31参照)。【選択図】図7
