PROBLEM TO BE SOLVED: To constitute a paddy field work machine which does not allow a soil-covering member to push out mud forward but allows the mud to be pushed into a groove on a lateral side from the soil-covering member appropriately even when the mud is hard or little water is present on a field face.SOLUTION: The paddy field work machine includes soil covering members 31 and 37 which plunge into a field face at a lateral position of a furrow forming implement and push mud into a groove during traveling of a machine body, thereby fill the groove having been supplied with a farm granule. Each of the soil covering members 31 and 37 includes: an upper part 41a in a lateral direction along the field face; a first rear part 41b extending downward from a rear portion of the upper part 41a; and a second rear part 42 extending downward from the first rear part 41b and plunging into the field face. The position of the second rear part 42 with respect to the first rear part 41b is changed vertically along the first rear part 41b, thereby a plunging depth of the soil-covering members 31 and 37 into the field face is changed freely.SELECTED DRAWING: Figure 8 |
