Claims (1)
- 耕耘爪軸に取り付けられる取付基部から連続して延びる縦刃部及び横刃部を有し、前記縦刃部から前記横刃部にかけて回転方向と逆向きに弯曲するとともに、一側方に弯曲して弯曲内側にすくい面を形成した耕耘なた爪において、
前記横刃部は、略一定の曲率半径で一側方に弯曲し、該曲率半径が、前記取付基部から前記横刃部の折曲開始部分までの爪軸軸心方向の側面視における水平長さより短い長さとし、
前記すくい面は、前記耕耘なた爪の側面視において、前記耕耘なた爪の爪軸中心を円の中心としたときに、回転半径として最大となる点における接線と、前記すくい面を構成する前記横刃部の先端部の断面を形成する線とのなす角が鈍角であり、
前記すくい面を構成する前記横刃部の先端部の断面形状は、一側方に弯曲する該横刃部の弯曲内側方向と同方向側に一定の曲率半径を有して凸状に弯曲している
ことを特徴とする耕耘なた爪。
