Abstract

An up-and-down control device for rice transplanter, which connects rice transplanting device, which is drived by transmission mechanism and can move up-and-down, on the main body; based on the variation of ground contact pressure, which is measured by the ground contact sensor of the rice transplanter, the rice transplanting device can move up-and-down and the transmission mechanism is controlled within the target level; which is characterized in: installing a non-sensing band in the dividing zone of the control target level; the up-and-down control device is equipped with a control device which ascends the transmission mechanism when the detection result of the ground contact sensor exceeds the upper limit of the non-sensing band of the control target level and descends the transmission mechanism when the detection result of the ground contact sensor exceeds the lower limit of the non-sensing band of the control target level.
