An anti-tangle bracket assembly has a first pivot link coupled to the harrow drawbar and a second pivot link pivotally coupled to the at least one harrow rank. The first and second pivot links pivot about pivot axes with respect to one another within a pivotal range of movement of the at least one harrow rank from a first, extended position to a second, tripped position.
