TRANSMISSION CASE ARRANGEMENT STRUCTURE FOR RIDING RICE PLANTING MACHINE

摘要

PROBLEM TO BE SOLVED: To enhance the longitudinal center-of-gravity balance by arranging a mission case in a position under an engine so as to vertically overlap the engine, and arranging the front end of the mission case in a rear position from the virtual tangent of a front wheel connecting the front end of the machine body to the front side part of the front wheel. SOLUTION: A mission case 5 is arranged in a position under an engine 2 so that at least a part thereof vertically overlaps the engine. The front end of the mission case 5 is arranged in a rear position from the virtual tangent L connecting the front end of the machine body to a front wheel 7. According to this structure, the center-of-gravity position of the whole body of a this riding rice planting machine is moved forward and downward to enhance the longitudinal center-of-gravity balance. The front end of the mission case 5 is arranged in the rear position from the virtual tangent L, whereby the collision of the mission case 5 to a stepped part such as ridge can be eliminated in getting over the stepped part to prevent the breakage of the mission case 5.
