ABSTRACT:
A cultivator which may be attached to a tractor or similar vehicle for use in cultivating rows of plants, includes a rotary tine assembly having a plurality of vertically-oriented, rotary tines for cultivating soil on each side of a row of plants; shields associated with each row of plants for limiting throwing of soil by the rotary tines; a drive motor for moving the rotary tines to cultivate the soil; and a support structure for securing the rotary tines, the shields, and the drive motor thereto and which is adapted for connection to the tractor or similar vehicle, wherein dimensions of and relative adjustments of the tines and the shields are chosen so that a predetermined amount of soil passes between selected shields, whereby weeds between adjacent rows of plants may be uprooted and/or destroyed and soil may be ridged and heaped around the plants and in the rows.
