2. Description of the Related Art Conventionally, as a mudguard cover structure for a rice transplanter of this type, a leveling float is arranged immediately behind a rear wheel as disclosed in, for example, Japanese Patent Laid-Open No. 6-70624. As a result, there was a high possibility that mud that was blown backward by the lugs of the rear wheels etc. when traveling in the field would drop and adhere to the top surface of the ground float, especially on the front side. To prevent this, a vertical wall is erected at the front end of the ground leveling float, and the vertical wall covers the structure that prevents mud from splashing behind it or is suspended from the fixed part of the seedling planting device. A structure has been proposed in which the body is disposed on the front side of the ground leveling float, and the cover body prevents the dirt from splashing behind.
