Claims (1)

[Scope of utility model registration request] Both wheels 4 are tilted horizontally by a sensor arm 3 whose intermediate portion is pivoted on a fulcrum shaft 2 with both sensor floats 1a and 1b interlocked at both ends so as to be able to move up and down.
In a rice transplanter configured to be able to automatically control the machine body to a lateral horizontal posture while moving the a and 4b up and down, the correction arm 5a has a tapered surface that can correct the posture to a horizontal posture when it comes into contact with the sensor arm 3. , 5b are constructed so as to be movable back and forth with respect to the sensor arm 3, and both wheels 4a, 4b
The above-mentioned correction arms 5a and 5b are connected to a planting clutch lever 7 which is linked to a hydraulic lever 6 for vertical movement operation so that the correction arms 5a and 5b move in a horizontal position toward the sensor arm 3 side when the planting clutch is cut. A device for correcting vertical motion of both wheels.
