PROBLEM TO BE SOLVED: To achieve in a simple structure that ground supply materials released on a field with material-feeding members are not dislocated in the travel direction, even when the biting clutch of a power transmission mechanism is subjected to a power retransmission operation at any timing.SOLUTION: The working machine is characterized in that the power transmission mechanism has the first transmission system for transmitting rotation power to the first material-feeding member 30 and the second transmission system for transmitting rotation power to the second material-feeding member 30 biting clutches CL1 for engaging or disengaging with the transmission of power at a rotation angle pitch for the clutch operation of a prescribed rotation angle enabling biting are disposed in the transmission systems and the feeding rotation angle pitch and the rotation angle pitch for clutch operation are disposed so that the feeding timing of the ground supply material with the first material-feeding member 30 and the feeding timing of the ground supply material with the second material-feeding member 30 do not change, when the power is retransmitted after the power interception of the biting clutches CL1.COPYRIGHT: (C)2013,JPO&INPIT【課題】動力伝達機構の咬合クラッチをどのようなタイミングで動力再伝動操作しても、それぞれの物体繰出し体によって圃場に放出された対地供給物体の走行方向位置ずれがないことを、簡単な構成で実現することである。【解決手段】第1の物体繰出し体30に回転動力を伝達する第1の伝動系統と第2の物体繰出し体30に回転動力を伝達する第2の伝動系統とを有し、伝動系統には噛み合いが可能となる所定回転角度であるクラッチ動作回転角度ピッチで動力伝達の入り切りを行う咬合クラッチCL1が設けられ、咬合クラッチCL1の動力遮断後の動力再伝動時における第1の物体繰出し体30による対地供給物体の放出タイミングと第2の物体繰出し体30による対地供給物体の放出タイミングが変化しないように繰出し回転角度ピッチとクラッチ動作回転角度ピッチが設定されている。【選択図】図1
