1. A universal custom agricultural field preparation implement comprising:
a mainframe having a plurality of connected transverse and longitudinal tubular frame members; a plurality of support wheel assemblies coupled to the mainframe, each support wheel assembly having at least one wheel for supporting the mainframe and having at least one hydraulic wheel actuator for lowering the at least one wheel to selectively vertically position the frame for soil tillage operations and for raising the frame for transport over the soil or highway; a framed tongue assembly connected to the front end of the mainframe in pivotable relation, the tongue assembly having a front end attachable to a tractor drawbar to power and control movement of the implement, and having a frame pivoting actuator pivotally linking a pin mounted on the tongue a distance forward of the pivotal connection of the tongue to the mainframe with a first distal end of an intermediary pivotal link which is pivotally linked at an intermediate portion of the intermediary link to an upwardly extending portion of the front end of the mainframe, the intermediary link itself being further pivotally linked at a second distal end to a rear link which extends rearwardly from the front end of the mainframe or operative pivotal connection to the wheel assembly, the first and second distal ends being physically separated from the intermediate portion of the intermediate link and from each other, a plurality of soil working components coupled to the frame, said components further comprising: a plurality of front disc gangs flexibly connected to the front portion of the mainframe such that the disc gangs extend generally beneath a front frame portion and when in contact with the soil are the first working component of the implement to engage the soil as the implement travels forwardly across the soil, the front disc gangs being adjustable between positions generally perpendicular to the line of travel of the implement and positions forwardly angled from the perpendicular, each disc gang comprising a plurality of spaced, shallowly outwardly concaved discs rotating about the axles of the disc gangs to directionally engage the soil from generally parallel with to an acute angle to the line of travel; a plurality of chopping reel assemblies connected to the mainframe and aligned closely behind the front disc gangs and immediately forward of the support wheel assemblies, each chopping reel assembly having a rotatable chopping reel having a plurality of shallow helical blades which extend outwardly from the chopping reel to provide an effective cylindrical array of spaced helically extending blades which slice vertically into the soil and through any fibrous material on or within the soil surface to at an angle generally perpendicular to the line of travel, the chopping reels being independently hydraulically controlled to permit engagement of the reels at a desired soil depth or raising and disengaging the reels from the soil during any configuration of the mainframe and during any tilling operation; a plurality of rear disc gangs flexibly connected to the mainframe immediately and closely behind the support wheel assemblies such that the rear disc gangs extend generally beneath a rear mainframe portion and when in contact with the soil are the third working component of the implement to engage the soil as the implement travels forwardly across the soil, the rear disc gangs being adjustable independently of the front disc gangs between positions generally perpendicular to the line of travel of the implement and positions rearwardly angled from the perpendicular, each disc gang comprising a plurality of spaced, shallowly inwardly concaved discs rotating about the axles of the disc gangs to directionally engage the soil from generally parallel with to an acute angle to the line of travel; and whereby the frame pivoting actuator, mainframe and at least one support wheel assembly may be selectively adjusted to lower the front mainframe portion and raise the rear mainframe portion to cause the front disc gangs to be substantially engaged with the soil and the rear disc gangs to be more shallowly engaged to not engaged, and conversely may be adjusted to raise the front mainframe portion and lower the rear mainframe portion to cause the rear disc gangs to be substantially engaged with the soil and the front disc gangs to be more shallowly engaged to not engaged. |
