ABSTRACT The invention disclosed relates to a mechanism for adjusting the level, tine working depth, and tine working angle of a framework supporting a multiplicity of cultivator tines. The framework is cantilevered from and behind a boom drawn on wheels, and includes a pair of rock shafts that are: 1) rotated together to adjust the working depth of the tines, 2) rotated relative to one another to adjust the level of the working depth of the tines; the working angle of the tine is adjusted by mechanical rotation of frame tubes forming part of the framework and on which the tines are directly mounted. The invention disclosed also includes a novel hydraulic circuit for powered rotation of the transverse frame tubes and of the boom between a working position when the tines are engaged with the ground and a transport position when the tines are clear of the ground an? the framework carried in a position facilitating transport.
