逆転両用耕耘爪の取付は構造。A pair of left and right brackets 23 and 24 having a U-shaped cross section
are erected on the claw shaft 22 in a facing manner with a U-shaped recess 26 facing outward and a gap in which the tilling claw 25 is loosely fitted;
One bracket 23 has a bolt thread insertion hole 28 parallel to the axis of the pawl shaft, and a counterbore hole 29 concentric with the insertion hole is provided at the inner end of the insertion hole. An oval-shaped bolt neck insertion hole 30 with a large diameter and concentric with the counterbore hole is opened in the hole, and the bolt neck insertion hole 30 has a large diameter and is concentric with the counterbore hole.
A claw pivot bolt 32 is inserted through the threaded part 33 which is inserted into the threaded part insertion hole and projects outward.
It integrally includes a claw branch 34 that fits into the counterbore hole, an oval neck 35 that fits inside the outer end of the neck insertion hole, and a head 36 that locks on the end surface of the recess, The bolt is fixed to the bracket 23 by a nut 37 screwed into the threaded part, and the tilling claw 25 located in the gap between the brackets is rotatably supported on the claw support, and the neck is inserted into the neck insertion hole. The installation structure of the tilling claw for both forward and reverse use is characterized by a disc spring 39 interposed in the claw branch between the claws.
