A coulter adjusting device for use in a reversible plowing machine having a non-reversible mast frame (20), a bottom frame (10) secured to the non-reversible mast frame (20) in such a manner as to be rotatable or reversible relative to the non-reversible mast frame (20), a rotatable shaft (17) for rotating or reversing the bottom frame (20), plural pairs of bottoms (14a,14b) fixed to the bottom frame (20) such that each pair of bottoms (14a,14b) are secured to upper and lower sides of the bottom frame (20) respectively, and coulters (37,16) provided in correspondence with each pair of bottoms (14a,14b), at least one of the coulters (37,16) being secured to the non-reversible mast frame (20), including means for adjusting the position of the coulter (37) secured to the non-reversible mast frame (20) by inclining the coulter (37) on a plane perpendicular to a plowing direction by an angle corresponding to the plowing depth, or by moving the coulter (37) in the plowing width direction by an amount corresponding to the tread of a tractor interlockingly with a reversing operation of the bottom frame (10).
