TILLAGE TINE-ATTACHING DEVICE

摘要

PROBLEM TO BE SOLVED: To reduce the time and labor for attaching and detaching a tillage tine of a tilling rotary. SOLUTION: Cross sections of a hollow tine-holder 2 fixed to a tillage shaft 1 and a tillage tine 3 to be inserted therein are formed into nearly diamond shapes, and the tillage tine 3 is narrowly pressed into the tine-holder 2 so as to be supported by the contact of both inclined surfaces. A lock pin for engaging the tillage tine 3 with the fixing base part side at the rear side in the rotary direction of the tine-holder 2 is installed therein.
