Abstract
Representative implementations of devices and techniques provide a tool bar comprising a structure having a plurality of sections arranged in geometric forms. The geometric forms may change shape to keep a tool that is attached to the structure in a desired position while the tool bar is being used on uneven terrain, such as on a hillside or while the tool bar is rotated or pivoted at an angle with respect to the direction of travel. Changing the shape of the geometric forms can also result in rotating the tool attached to the structure with respect to the tool bar.
