ABSTRACT:
The device includes (i) a supporting frame for connection to a draft source, this frame having a plurality of laterally positioned rigid supporting sections each hinged to its laterally adjacent section; (ii) a plurality of working sections corresponding to the respective supporting sections, the working sections each comprising (a) tandemly positioned transverse harrow bars secured together for independent vertical and pivotal motion with respect to each other, and (b) downwardly disposed harrow teeth secured to the harrow bars; and (iii) connectors flexibly securing the working sections to their corresponding supporting sections so that when in harrowing position a working section underlies its supporting section. At least one of the outboard supporting sections together with its working section can be rotated as a unit around a longitudinal axis between prone and upstanding positions.
