PROBLEM TO BE SOLVED: To provide a ground making float for a rice field working machine, which is enabled to perform the planting satisfactorily even with a width corresponding to the whole ridge by suppressing still more the adverse effect on the adjacent ridge due to a mud push.SOLUTION: Wave preventing plates 30 for suppressing the diffusion of a mud wave to the transverse outsides of a ground making member 20 are arranged at such a spacing d from transversely outermost side end edges 21b of the ground making member 20 as to allow the mud wave established according to the progress of the ground making member 20 to pass to the rear side, and are made longer than the longitudinal length at the transversely outermost side end edges 21b of the ground making member 20. |
