1. A strip-till row apparatus for preparing soil for planting, comprising:
a primary frame having a pair of spaced apart side panels, each side panel having a generally upstanding front edge and an opposed upstanding rear edge, said primary frame having a cross brace extending between said pair of side panels; a tillage assembly operatively coupled to said primary frame adjacent said rear edges thereof, said tillage assembly being configured to contact a ground service so as to prepare the soil; an auxiliary frame having an upstanding front wall and a mounting arm extending rearwardly from said front wall, said auxiliary frame having at least one linking member having a first end pivotally coupled to said front wall and an opposed second end coupled to said primary frame adjacent a respective front edge of a respective side panel; an airbag having a top coupled to said mounting arm and a bottom coupled to said at least one linking member via an airbag mounting bracket, said airbag being selectively inflated with air; wherein said primary frame is raised or lowered by pivotal movement of said at least one linking member as said airbag is selectively inflated or deflated, respectively; a mounting bracket extending upwardly and rearwardly from said cross brace, said mounting bracket having a pair of spaced apart side walls and pair of spaced apart pins extending between said pair of side walls; and an adjustment guide member having opposed upper and lower ends and defining a plurality of adjustment holes adjacent said upper end, said guide member being positioned relative to said mounting bracket so as to move slidably between said pair of pins; wherein said guide member includes a collar coupled to a selected hole of said guide member, said collar having a dimension larger than a space between said pair of pins so as to allow a selectable range of slidable travel of said guide member relative to said mounting bracket; wherein said tillage assembly is operatively coupled to said lower end of said adjustment guide member so as to move up or down with said travel of said guide member. |
