Claims

[Scope of utility model registration request]

A lift control float for a rice transplanter, which is pivotably supported to be vertically swingable with the rear end side as a fulcrum, and is provided on the side part with the planting mud surface leveling part 19 positioned above the bottom part of the float, A groove 20 for flowing muddy water is provided at the bottom of the float, extending from the front end or a part near the front end to the rear end, and the cross-sectional area of the rear end is the same as or larger than the cross-sectional area of the part near the front end. In this state, the depth Dl of the rear end portion is smaller than the depth D2 of the portion near the front end, and furthermore, the inner groove surface 20a at the rear end becomes a downwardly inclined surface and the inclination angle a is A lift control float for a rice transplanter, characterized in that the float is formed so that the rear end side is looser than the front end side.
