Abstract
The invention discloses a differential connecting rod and draft cable for an agricultural tillage device. The invention consists of a differential connecting rod which is positioned parallel to the center frame. The center frame is connected to the inner wing frame by a universal joint. The universal joint has a spherical bearing and a pivot. The pivot is positioned in a slot. The differential control rod positions the pivot in the slot. An `L`-shaped linkage and a spring assembly pivotally support the rod. The draft cable is attached to the center frame hitch and outer wing. It is supported in the center by a folding support arm. This allows the wire to be moved when the cultivator is being transported. The draft cable transfers the draft force exerted on the outer wing to the center frame hitch.
