ことを特徴とする田植機における切換バルブ。In a switching valve that operates a control system that moves the float up and down relative to the machine body using pressure applied to the float from the field surface, and moves the planting device up and down by sensing the rise and fall of the float with respect to the machine body, the switching valve operates in a valve chamber. A damper chamber is formed at the end of the damper chamber, and the damper chamber is communicated with the hydraulic chamber through a check valve and a throttle passage. A switching valve for a rice transplanter, characterized in that the switching valve is configured to fit into the rice transplanter.
