The disk 18 is arranged substantially next to the rear wheel of the tractor, and the disc 18 is rotatably attached to the lower surface of the horizontal bottom plate 21 that fixes the above-mentioned skid portion 17 to the main pipe 16 by a shaft 22, and as shown in FIG. When seen in a plan view, the outer peripheral edge is arranged so as to project further forward than the tip of the clearance portion 17 and outward than the outer edge.

A rectangular tubular body 23 is externally fitted and inserted in a position above the clearance portion 17 in the middle of the main pipe 16, and the tubular body 23 is, as shown in FIG. 1 and FIG. The position adjusting bolts 24 provided on the upper portion are inserted into the adjusting holes 25 provided at regular intervals in the axial direction of the main pipe 16, and the fastening bolts 26 are tightened with respect to the cylindrical body 23 to adjust the adjusting holes 25. It is fixed so that the position can be adjusted vertically at intervals of. This vertical adjustment is to adjust the plowing depth.

As shown in FIG. 2, a horizontal arm 27 projecting rearward is fixed on the inner side surface of the cylindrical body 23, and a supporting rod 29 is movable in a right angle direction by a rectangular cylindrical portion 28 provided in the middle of the arm 27. The vertical roller 19 is rotatably pivoted at a position on the lower surface side of the outer end portion of the support rod 29, and the holes 30 and the square tubular portion 2 are provided at regular intervals in the length direction of the support rod 29. By selecting the fitting of the pin 31 screwed into the vertical roller 8, the vertical roller 19 can be laterally adjusted in position.

As shown in FIGS. 2 and 3, a horizontal roller 20 located outside of the vertical roller 19 and above the vertical roller 19 is rotatably pivoted to the outer surface at the rear end of the arm 27. The horizontal roller 20 is attachable to and detachable from the arm 27 by using a pin 41 and a bolt.

The outer peripheral edge of the vertical roller 19 and the lower peripheral edge of the horizontal roller 20 have a right angle relationship when viewed from the front, and when the processing device 11 processes the edge of the ridge 1, the horizontal roller 2 0 rests on the upper flange 3, and the vertical roller 19 contacts the side surface of the upper flange 3.

At this time, as shown by the solid line in FIG. 2, the disk 18 attached to the tip of the gap 17 comes into contact with or approaches the web 2.

In order to attach the upper portion of the main pipe 16 to the attachment pipe 15, a rectangular tube-shaped holder 32 is vertically fixed to the tip of the attachment pipe 15, and the main pipe 16 that vertically penetrates the holder 32 is attached to the holder 32.
