Abstract
A field cultivator frame has a number of generally horizontal implement frame sections, each frame section having ground engaging wheels for movable support over the ground. First and second center frame sections are pivotally connected to a prime mover by a hinged draw bar assembly. Front ends of the center frame sections are pivotally connected by a flex link assembly including a connecting bar with ball joint connections at either end. The flex link assembly allows vertical movement of the center frame sections relative to one another, which movement is limited by a plate assembly attached to one of the center frame sections. A swivel joint assembly connects rear parts of the first and second center frame sections for allowing hinged movement of the frame sections relative to one another. A spring-loaded limit assembly connects the first and second center frame sections and includes compression springs for resilient limiting of relative movement of the center frame sections. First and second outer wing sections are hingedly connected to the first and second center frame sections, respectively. Rearward ground engaging wheels associated with the center frame section are located in line with the hinge connections, obviating the need for wheel pockets in the interior frame.
