Multiple section draw bar

Abstract From the Canadian patent

A drawbar having a boom with at least two pivotally connected sections which in a field position extend generally transversely of the direction in which the draw bar is drawn. Each section carries at least one first soil working device and at least one other second soil working device is trailed behind said first soil working device. The sections are pivotable in unison, about a horizontal axis transverse to the direction in which the drawbar is drawn, from said field position to a non-working position. In the non-working position both the soil working devices are raised in order that the sections can be pivoted relatively to each other to a folded transport, position.
