Filed: 1993-09-21
Abstract: PURPOSE:To remove hindrance on carrying out through integrated mechanization of operations in rice raising and improve stability of traveling car body, especially in a small-sized riding rice transplanter. CONSTITUTION:An interval between left and right wheels in traveling car body 1 is arranged over all rows so as to be longer than whole planting width in a seedling transplanter 3.

Since lengths of a line-drawing maker 18 and a row matching maker 30 are set so that adjacent interrow space L2 between seedling group and seedling group planted by the seedling transplanter 3 becomes wider than a planting interrow space L1 of the seedling transplanter, mud pressing of wheels to an adjacent row is slight even in the constitution of wheel arrangement over all rows. Further, after planting the seedlings, adjacent interrow space L2 becomes wider than the planting interrow space L1. As a result, a controller can smoothly be travelled through the interrow space and further, the interrow space matches with reaping width of a combine harvester.
