The present invention provides a tillage point having a ground engaging structure configured to adjust with respect to the ground so that the tillage point can flexibly adapt to various field conditions. The ground engaging structure can comprise wings for increasing soil fracture below the ground surface and/or a cover board for moving soil along the ground surface. The ground engaging structure can variably adjust using an actuator, such as a hydraulic cylinder, connected to linkage which can move the ground engaging structure through multiple angles about a pivot point during tillage operations. In addition, a controller can adjust the actuator to maintain an angle of the ground engaging structure according to a location on a prescription map.

A tractor mounted tiller/cultivator system that includes right and left swing arms pivotally attached to tractor chassis, right and left cutting head assemblies mounted on the swing arms, each including a right disc motor driving a rotary disc mounted on a distal portion of the swing arm and operatively coupled to the motor. Ground-engaging cultivation wheels surround the rotary disc, and an annular guard prevents unwanted contact of the wheels with vines or trunks of vines and trees. A drive mechanism lowers and raises the swing arms to put the cultivation wheels into engagement and disengagement with ground and to rotate said swing arms about their longitudinal axes. User controls operatively connected to the swing arms, cutting head assemblies, and drive mechanisms enable a user to finely tune the movement of the cutting heads into and out from rows of trees or vines.
