特徴とする田植機の植付制御装置。 It is equipped with a rolling regulating spring that regulates the rolling of the planting section, and a spring pressure adjusting member that adjusts the spring pressure of the regulating spring, and the above-mentioned pressure is adjusted through the spring pressure regulating member based on the detection of the inclination of the planting section by the left and right float sensors. In the structure in which the spring pressure of the regulation spring is adjusted to maintain the planting area horizontally, a neutral return element is provided which returns the spring pressure adjusting member to a neutral state when the left and right float sensors are not in contact with the field surface. Characteristics of the rice transplanter's planting control device.
