Abstract
A power harrow has a frame that is normally substantially horizontal and at least one rotor. A rotatable shaft is journalled near one end in a bearing secured to the frame. The rotor is in driven connection with the other end of the shaft, and is rotated about a normally upright axis, so as to make contact with the soil to work it. A protective shield surrounds the bearing from below.
