機の走行装置における制御装置。A pair of left and right wheels are attached to the left and right sides of the machine body equipped with the seedling planting mechanism so that they can move up and down independently. The main hydraulic cylinder drives the left and right wheels so that they move up and down at the same time by operating a switching valve that switches according to the detection, and the left and right wheels move up and down relative to each other by operating a switching valve that switches according to the horizontal tilt of the aircraft. It is connected to a rolling hydraulic cylinder that drives it up and down in the opposite direction.
A hydraulic circuit is configured to send hydraulic pressure from one hydraulic pump to a switching valve for the main hydraulic cylinder, and from the switching valve to a switching valve for the rolling hydraulic cylinder,
A control device for a traveling device of a walk-behind rice transplanter, wherein the volume of the main hydraulic cylinder is larger than the volume of the rolling hydraulic cylinder.
