The present invention relates to a walk-type paddy field in which agricultural equipment for paddy fields such as rice planting devices and seeding devices is attached to the rear part of a traveling vehicle body provided with left and right traveling wheels whose relative vertical positions can be changed. Conventional agricultural machinery, as shown in Japanese Utility Model Publication No. 55-25216, a grounding float is provided in the center of the machine between the left and right traveling wheels whose relative vertical position can be changed. There is a rice transplanter equipped with a grounding float on the outer side of the fuselage whose outer surface is located in the grounding float on the outer side of the fuselage. Since it detects the left-right inclination of the body, there is a drawback that the ground contact float contacts the ridge when traveling on the ridge, and the control cannot be performed accurately. It is an object of the present invention to solve the drawbacks and to obtain a walk-type paddy farming machine that enables proper farming work.

Next, the operation of the above example will be described. The seedling tank (32)
After putting three soil mat-shaped seedlings on top, when each part is driven by the engine (5), the traveling vehicle body makes a pair of left and right traveling wheels (7a), (7b) that come into contact with the platter surface, and the left and right traveling wheels. Ground float (20), located between the wheels and grounded on the soil surface,
(21a), (21b) and the float (36
a), (36b) and traveling wheels (7a),
It is propelled by the rotation of (7b). Then, the rice planting device (31) at the rear plant three rows of seedlings one after another.

At this time, if the depth of the cultivator is changing and the traveling wheels (7a) and (7b) on either side enter into the depth, the supporting force of the airframe decreases and the airframe leans to that side. Ground float (21a), (21b) as the ground pressure increases, it moves upward, and the hydraulic switching valves (15a), (15b) on that side are switched to project the piston, and the traveling wheel (7a) on that side. , (7b) is moved downward, grounded on the cultivator to restore the tilt of the machine, and when it is restored to a substantially horizontal state, the hydraulic switching valves (15a), (15b)
Becomes neutral and stops the downward movement of the traveling wheels (7a), (7b).

Also, when one of the traveling wheels (7a) and (7b) touches the cultivator where the rising surface is inclining to tilt the machine, the grounding floats (21a) and (21b) on that side tend to float and touch the ground. Since the pressure is reduced, the oil pressure switching valves (15a) and (15b) are switched in the opposite way to the above, so that the oil in the cylinder is returned to the tank and the pistons (11a) and (11b) can be withdrawn. The traveling wheels (7a) and (7b) move upward. In this way, the tilting of the body is restored.

At this time, since the left and right ground floats (21a) and (21b) are supported by the center ground float (20), the aircraft does not suddenly lean to the left or right, and control is performed rapidly. Since the aircraft does not oscillate left and right unnecessarily, stable running is performed, and fluctuations in the planting depth of the seedling planting strips on the left and right ends can be reduced.
