正構造。[Scope of Claim for Utility Model Registration] A planting section C is connected to the rear of the traveling section B and has a float 20 mounted below that slides on the planting surface of the field so as to be able to rise and fall up and down by a hydraulic lifting mechanism D. A sensor S connected in conjunction with a hydraulic control valve 69 that controls the hydraulic lifting mechanism D is provided between the float 20 and the planting section C, and the sensor S detects the vertical movement of the float 20 and operates the hydraulic lifting mechanism D. In a riding rice transplanter configured to hold the planting depth of seedlings constant by supporting the planting part C at a constant height from the planting surface, the sensor This riding rice transplanter sensor sensitivity correction structure is provided with a sensor sensitivity correction means G that corrects the sensitivity of the sensor S by pressing and urging the float 20 toward the planting surface side in conjunction with a changing operation.
