請求項１記載の田植機の植付部昇降制御装置。[Scope of Claim for Utility Model Registration] 1. A float is provided with a front sensor arm and a rear sensor arm, sensor wires are connected to the front sensor arm and the rear sensor arm, and ground pressure of the float is detected from the front and rear parts of the float. In a rice transplanter's planting section elevation control device that freely controls the elevation of the planting section, a sensor wire is connected to the front sensor arm, and the rear sensor arm is made to freely come into contact with the front sensor arm to control displacement at the front of the float. 1. A device for controlling the elevation and descent of a planting section of a rice transplanter, characterized in that the elevation and descent of the planting section can be controlled easily in response to the motion. 2. The front sensor arm has a plurality of link-like members that are directly connected to the front of the float and are vertically installed, and the rear sensor arm is equipped with a spring to suppress the amount of displacement that enters from the rear of the float. 2. The planting part elevation control device for a rice transplanter according to claim 1, wherein the displacement amount at the front part of the float is increased by the above.
