The present invention relates to a harrow mounting structure provided with a reverse driving shock absorbing function and, more particularly, to a harrow mounting structure provided with a reverse driving shock absorbing function which is moved forward for shock absorption and harrow damage prevention in a case where a harrow is stuck in a paddy field during reverse driving of a tractor in an harrow operation or the harrow is excessively lowered during a course of paddy field soil movement. The harrow mounting structure according to the present invention includes: a pair of horizontal axis fixing tools which are coupled to a horizontal axis of a rotary and have a harrow frame being disposed on one side; a horizontal frame which connects the horizontal axis fixing tools to each other and has a cylinder bracket being provided in a central portion; and a supporting frame with one side connected to an upper portion of the rotary and the other side connected to the cylinder bracket or the central portion of the horizontal frame. The supporting frame is configured to have a supporting rod which is connected via a connection shaft to the upper portion of the rotary, and a rotating plate which connects the supporting rod and the cylinder bracket or the horizontal frame to each other and is provided for an installation position thereof to be maintained by a position fixing means. In a case where the harrow is excessively lowered or the harrow is stuck in the paddy field during the reverse driving of the tractor, the resultant pressure cuts or deforms the position fixing means so the harrow mounting structure pivots forward about the horizontal axis. |
