ABSTRACT:
Individual tool bars are mounted between upright guides of a horizontal rectangular frame. Rollers engaging the guides transmit longitudinal forces from the frame to the tool bars and allow the tool bars to move freely up and down. Ground working tools mounted to the bars can therefore "walk" over uneven terrain as controlled by balancing depth wheels and packer wheels. Hydraulic cylinders are mounted between the tool bars and frame for applying upward or downward force against the tool bars without inhibiting their free movement along the guides in response to ground contour.
