Abstract
A row cultivator (10) includes a row following system (12) coupled to a toolbar (13) employing frame members (17) and (18) constrained to remain parallel by a cross member (21). Coulter wheels (30) and (31) secured to the frame members (17) and (18) are non-steerable and tool bar drift may be corrected. A tool (40) employs a leading blade (44) and a pair of diverging cutting blades (47) and (48) trailing behind the leading blade (44). A sheer release assembly employs a longitudinally extending bolt (70) centrally disposed and holding a shank (61) to a tool bar (65) so that when a tool on the shank (61) strikes an underground obstacle the bolt (70) is sheared longitudinally.
