A harrow attachment for a tillage implement has a harrow drawbar, configured to mount to a frame member of the tillage implement, and at least one harrow rank having a rank bar supporting a plurality of harrowing tools oriented to extend away from the rank bar. 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.

A harrow attachment for a tillage implement includes a harrow drawbar mounting at least one rank of harrowing tools. A pivot link pivotally couples the harrow rank to the drawbar so it can trip by pivoting upward toward the drawbar from a home position in which the harrow rank is farthest away from the drawbar. A downforce spring is coupled to the drawbar and in a variable length state when the harrow rank is tripped to apply a return biasing force to the harrow rank. An adjustment mechanism couples the spring to the harrow rank and/or the pivot link in one of a plurality of adjustment locations in each of which the harrow rank is in the home position and the spring is in a fixed length state in which the biasing force is removed.

A harrow apparatus is provided. The harrow apparatus can have a main frame mounted on ground wheels for travel along a ground surface in a travel direction, a hitch assembly attached to a front end of the main frame and operative to connect to a tow vehicle, and a harrow section connected rearwardly of the main frame, the harrow section having a plurality of tines extending downwards to engage with the ground surface. The plurality of tines can include a first set of tines having a first diameter, and a second set of tines having a second diameter. The first diameter of the first set of tines is larger than the second diameter of the second set of tines.
