Abstract

PURPOSE: To reduce the abrasion of connection between a support part and a blade edge part by a method in which part or the whole of connection part on the body side is subjected to a hardening treatment, while a part or the whole of connection part on the connection part side is subjected to a softening treatment.
CONSTITUTION: For a connection part for a land processing part functioning when being connected, part or the whole of connection part on the body side 4 is subjected to a hardening treatment, while a part or the whole of connection part on the connection part side is subjected to a softening treatment. For preventing settling in the front end portion of the support part 2, the front end portion of the part 2 is hardened by a method in which a hard part H at the tip of the part 2 is placed in a cast mold and then cast with the support part 2, and also to prevent the abrasion of the support part 2, the portion in contact with the support part 2 of the connection part of the blade edge part 1 is subjected to a softening treatment.
