Abstract
A precision steering apparatus, affixed to the tool bar of a row crop cultivator, includes a pair of transversely spaced and pivotally mounted coulter discs and a steering mechanism for pivotally moving the coulter discs in unison. A furrow follower mechanism detects lateral drifting of the cultivator implement relative to a guide furrow formed in the ground parallel to the rows of crops. The furrow follower mechanism is operatively connected to a power assist apparatus actuatable to pivot the guide coulters and thereby steer the implement back to its correct transverse position relative to the guide furrow.
