PROBLEM TO BE SOLVED: To provide a paddy field implement which has a paddy field working device ascendably/descendably connected to the rear of a traveling machine body, and which surely prevents mud scattered backward by rear wheels from being bonded to and accumulated on the respective portions of the paddy working device.SOLUTION: In this paddy working machine, a rear end of a rear wheel fender 55 for covering the rear wheel 2 of the traveling machine body 3 from above is extended downward. The rear end of the rear wheel fender 55 is moved upward and downward in the same direction as the direction of the ascent/descent of the paddy working device 6 in synchronization with the ascent/descent of the paddy working device 6.COPYRIGHT: (C)2008,JPO&INPIT【課題】 走行機体の後部に水田作業装置を昇降自在に連結した水田作業機おいて、後輪によって後方に向けて飛散された泥が水田作業装置の各部に付着堆積することを確実に防止する。【解決手段】 走行機体3の後輪2を上方から覆う後輪フェンダ55の後端を下方に延出するとともに、水田作業装置6の昇降に連動して後輪フェンダ55の後端を水田作業装置6の昇降方向と同方向へ上下移動させるよう構成してある。【選択図】 図1
