ABSTRACT:
A pull type minimum tillage implement includes a closed rectangular frame having a forward tool bar, intermediate tool bar and rear tool bar. The ground-working tools travel directly over each previous crop row and include a forward coulter mounted on the forward tool bar followed by a subshank and disk hiller mounted on the intermediate tool bar. A mounted planter may be connected to the rear tool bar while a drawn planter is connected under the rear tool bar to the intermediate tool bar. A pair of depth gauge and support wheel assemblies are provided directly over a pair of rows and include spaced apart frame members extending between the three tool bars with a ground wheel pivot arm positioned therebetween and pivotally connected to a bracket mounted on the front tool bar. A hydraulic cylinder pivots the frame about an axis through the forward end of the implement frame tongue thereby raising the rear end of the implement frame carrying with it the ground-working tools.
