Abstract
PURPOSE: To provide a deep plowing apparatus which tightens the plowed ground and at the same time forms seedbeds out of the tightened ground.
CONSTITUTION: A tightening member d is provided for pressing and tighting into the groove b the ground which is dug out by a digging member a and returned into the groove b. The tightening member d having a roll shape (15) is supported at the rotation end of an arm (16) provided rotatably in the vertical direction at the rear portion of the body 1 of the deep plowing apparatus and subjected to downward stress of a spring 17 through the arm 16. The tightening member d is located in such a position above the groove b behined the digging member a that corresponds to the position of the digging member a so that it can press down and tighten the ground into the groove b which is dug up by the digging member a and returned into the groove b heaping up over the groove b. The front shape of the tighening member d initates the outline of the seedbed to be formed in the cross section.
