A pivoted stop member on a drawn plow prevents lowering movement of the plow frame on the front furrow wheel to a normal plowing position when in a first position and to a land-opening position below the normal plowing position when in a second position. Provision is also made to independently adjust the normal plowing position of the frame with respect to the front furrow wheel and the land-opening position of the frame with respect to the front furrow wheel. |
