Rice transplanter

The invention provides a paddy field operation machine which is capable of reducing the soil attachment to one face of a seedling table facing the traveling machine, including: a rice transplanter member for performing the rice transplanting actions; the seedling table for loading the seedlings; and a sliding track arranged at the machine side of the paddy field operation machine and capable of slidingly supporting the lower part of the seedling table. The seedling table interlocks with the transplanting actions of the transplanter member and reciprocates along the sliding track, which is characterized in that a cover part is arranged between the machine body and the seedling table, a strut is used to mount an upper part of the cover part, and the lower part of the cover part is mounted on a landscape main frame which supports a transplanting transmission case, thereby preventing the soil to be attached on an operation member arranged on one side of the transplanter member facing the machine body or a landsca
