<p>Provided is a rice transplanter that detects the surface of a field, corrects deviations between the field ground-contacting surface detected by a float and the actual field surface, and detects an appropriate planting height, thus preventing planting defects. The rice transplanter, which is provided with a float that detects the field ground-contacting surface, is provided with a sensor that detects the field surface and that is provided separately from the float. The sensor has a detection unit, which tracks the field surface, and a support unit, which supports the detection unit in a manner able to oscillate, and the field surface height is detected by measuring the angle of oscillation of the detection unit when tracking the field surface.</p> |
