And the opening K on one side is closed by driving the operating motor 9a of the discharge position changing mechanism 9 and rotating the movable cover member 12 around the rotation axis O of the above-described rotating rotating body 8. Then, the opening F on the other side is formed, and in this state, the traveling machine body 1 travels along the old shaft in the clockwise direction opposite to the arrow direction in FIG. When the la is rotated, the mud in the field M that is spun up by the rotation in one direction N of the jumping rotary body 8 of the discharge position changing mechanism 9 has the opening F on the other side through the upper part of the movable cover member 12. Through the other side position L, and is guided to be released. Seiaze of the other side position L of the pair of left and right Seiaze 10, 10 arranged in a square position 10 is rotated in contact with the upper surface W ₁ and on the other hand side W ₂ of the ridge W of the other lateral position L the upper surface W ₁ and on the other hand side W ₂ of the ridge W rotates Seiaze Te, thereby resulting in the Seiaze work outstanding Seiaze processing portion T shown in FIG 15 is performed.

Therefore, the distance in the traveling direction between the drive shaft 13a disposed on the front mounting frame 3 in the traveling direction and the driven shaft 13c on the machine frame 4 side can be increased, and the amount of expansion / contraction of the transmission shaft 13f is accordingly increased. That is, the sliding amount of the outer cylinder 13g and the inner casing 13h can be reduced, and the swinging motion θ in the left-right direction B of the transmission shaft 13f by the movement of the machine frame 4 in the left-right direction B is smoothly performed. The frame 4 can be moved smoothly from side to side, the bending angle of the universal joints 13e and 13e can be reduced, the power can be transmitted smoothly, and the workability can be improved. Can do.

In this case, the interference avoidance position D is a position above the trimming mechanism 7 and the machine frame body 4, and the driven shaft 13 c is connected to the machine frame body 4 and the transmission shaft 13 f is connected to the machine frame body 4. Since it is arranged at a position where it crosses over, it does not hinder the movement of the machine body 4 in the left-right direction B, and constitutes a rectifying mechanism 7 arranged in the machine body 4 In this case, a power shaft 14a driven by the power take-off shaft 1a of the traveling machine body 1 is arranged on the mounting frame 3. Since the front transmission mechanism 14 is interposed between the power shaft 14a and the drive shaft 13a, the power transmission structure from the traveling machine body 1 to the straightening mechanism 7 can be simplified. In this case, the input shaft 15a is disposed on the machine frame 4 below the driven shaft 13c. Since the rear transmission mechanism 15 is interposed between the input shaft 15a and the driven shaft 13c, the power transmission structure from the traveling machine body 1 to the straightening mechanism 7 can be simplified. the pair of left and right Seiaze 10, 10 are formed symmetrically to each other, respectively, one side W ₂ of Seiaze possible top Seiaze portion 10a and ridges W upper surface W ₁ of the ridge W Seiaze Since it consists of the possible side surface trimming part 10b, the collar W can be reliably clamped.
