PROBLEM TO BE SOLVED: To solve problems that a transmission load in a rear wheel transmission case only on either the right or the left side is increased with the result that the driving force of the right and the left rear wheels is different and there is a risk of deteriorating straight advancing properties of a machine body if the transmission from the interior of the rear wheel transmission case only on either the right or the left side to a ground implement or a granule applicator is composed when each of the right and the left rear wheel transmission cases for driving the right and the left rear wheels is installed in an agricultural working machine.SOLUTION: The agricultural working machine is equipped with the ground implement and the granule applicator (8) on the rear side of a traveling vehicle provided with a pair pair of right and left front wheels and the pair of right and left rear wheels and each of the right and left rear wheel transmission cases (34) for driving the right and the left rear wheels. In the agricultural working machine, transmission mechanisms (36 and 37) for transmitting power from the interior of the rear wheel transmission case (34) on either the right or the left side to the ground implement and transmission mechanisms (40, 41, 42, 43 and 48) for granule application transmitting power from the interior of the other rear wheel transmission case (34) to the granule applicator (8) are installed.COPYRIGHT: (C)2008,JPO&INPIT【課題】 左右の後輪を駆動する左右各々の後輪伝動ケースを設けた場合、左右一方のみの後輪伝動ケース内から対地作業装置又は粉粒体施用装置へ伝動する構成とすると、この左右一方のみの後輪伝動ケース内の伝動負荷が大きくなり、ひいては左右の後輪の駆動力が相違して機体の直進性が悪くなるおそれがある。【解決手段】 左右一対の前輪及び後輪を備える走行車輌の後側に対地作業装置と粉粒体施用装置(8)とを設け、左右の後輪を駆動する左右各々の後輪伝動ケース(34)を設けた農作業機において、左右一方の後輪伝動ケース(34)内から前記対地作業装置へ伝動する対地作業用伝動機構(36,37)と、他方の後輪伝動ケース(34)内から前記粉粒体施用装置(8)へ伝動する粉粒体施用用伝動機構(40,41,42,43,48)とを設けた。【選択図】 図4
