PROBLEM TO BE SOLVED: To provide a traveling spreader configured not to perform double agricultural work at an adjacent position by obtaining positional information of the traveling spreader based on GPS signals.SOLUTION: Based on the positional information from GPS, the straight ahead direction of a machine body, and the adjacent working direction in which the machine body goes straight ahead by turning by 90 degrees after the machine body turns 90 degrees from a turn start position and reaches a turn back position (e position), are obtained the spray width of powdery grain from a fertilizer ejecting pipe is read in a traveling distance d1 between both directions is calculated from the obtained straight ahead direction and the adjacent working direction a traveling distance d2 between the adjacent working direction and the turn back position is calculated from the adjacent working direction a space (traveling distance d1-d2) is calculated by subtracting the space between the adjacent working direction and the turn back position from the traveling distance d1 the space (traveling distance d1-d2) between the turn start position and the turn back position is converted to the positional information so as to obtain the turn back position the drive of the grain powder spray device is stopped when starting the turn and the drive of a grain fertilizer spreader is started when reaching to the adjacent work position (f position).COPYRIGHT: (C)2011,JPO&INPIT【課題】GPS信号に基づき走行散布作業機の位置情報を得て、隣接位置での重複した農作業を行なうことがないようにした走行散布作業機を提供すること。【解決手段】GPSより得られる位置情報から機体の直進方位と、旋回開始位置から90度旋回して旋回戻し位置(e地点)に達した後、さらに90度旋回して直進する隣接作業方位を求め、肥料噴管からの粉粒体の散布幅を読込み、求めた直進方位と隣接作業方位から両方位間の移動距離d1を算出し、隣接作業方位から隣接作業方位と旋回戻し位置の移動距離d2を算出し、移動距離d1から隣接作業方位と前記旋回戻し位置の間隔を差し引いて前記間隔(移動距離d1-d2)を算出し、旋回開始位置と旋回戻し位置の間隔(移動距離d1-d2)を位置情報に変換して旋回戻し位置を求め、旋回を開始すると粉粒体散布装置を駆動停止させ、隣接作業位置(f地点)に達すると粉粒体肥料散布装置を駆動開始させる。【選択図】図12
