PROBLEM TO BE SOLVED: To bring digging penetration of the front end portion of a plow body to be good and prevent surfacing of the front end portion of the plow body by installing a friction receiving unit to the plow body and turning the front end portion of the plow body downward caused by contacting the friction receiving unit to farm soil and impurities on the farm field.SOLUTION: A farming field grader is provided. In the farming field grader, the plow body 12 is installed to be held in a state that the front part thereof is lower than the back part and be turnably pulled upward by a holding mechanism 9, and the friction receiving unit 36 is installed to turn the front end portion 12a of the plow body downward by contacting to farm soil and impurities on the farm field surface M, wherein the friction receiving unit includes a rod-like body protrudingly installed to the back face of the plow body.COPYRIGHT: (C)2009,JPO&INPIT【課題】すき体に設けた抵抗受け部は圃場土や圃場面上の夾雑物に接触することによりすき体の前端部は下向き回動させられ、このためすき体の前端部の穿入を良好にでき、すき体の前端部の浮上がりを防ぐことができる。【解決手段】すき体12を保持機構9により前下がり状に保持及び引き上げ回動可能に配設し、すき体に圃場土や圃場面M上の夾雑物に接触することによりすき体の前端部12aを下向き回動させる抵抗受け部36を設け、この抵抗受け部は上記すき体の裏面に突設された棒状体からなる。【選択図】図2
