| 2001 | Invention patented by Terrance A. Friggstad on January 17th, 2001. Abstract: The invention disclosed is a support for a draft cable in a multi-sectional agricultural tillage apparatus movable between an open operating position and a folded transport position. The draft cable is attached to the central frame hitch and an outer wing, and is supported along its length by a folding support arm attached to the inner wing frame. A mechanical mechanism interconnects the central hitch frame with the support arm such that the cable moves to a non-interfering position when the tillage apparatus is in the transport position. |
