A flexible tool bar apparatus including a first tool bar adapted to have earth working implements attached thereto and a second tool bar also adapted to have earth working implements attached thereto. Two tool bars are pivotally attached at the inner ends thereof. A hydraulic cylinder mechanism is operatively attached at one end thereof to the first tool bar and is operatively attached at the other end thereof to the second tool bar. A fluid device is provided for selectively supplying fluid under pressure to a hydraulic cylinder mechanism for causing the hydraulic cylinder mechanism to hold the tool bar from flexing. The tool bar can flex when the fluid pressure is released.
