Abstract
Abstract An agricultural implement, such as a field cultivator comprising at least two frame sections pivotally connected together in a side-by-side relationship. One frame section may be pivoted relative to the other frame section between a working position substantially in horizontal alignment with the other frame section and a transport position obliquely over the other frame section. Power means is provided for connecting the frame sections; the power means includes means for moving one of the frame sections from the working position to the transport position, and means for moving a frame section from the transport position to the working position.
