Abstract: A self-propelled agricultural tool carrier has a lifting carriage mounted between the front and rear sets of wheels. A tool bar adapter is mounted to the lifting carriage below the frame for connection to a tool bar that supports planting and cultivating equipment. Laterally spaced-apart stabilizing legs are rigidly mounted to the frame and extend downward along opposite sides of the lifting carriage. The tool bar has a pair of braces, each of which engages a support member on a lower portion of each of the stabilizing legs to restrain the tool bar against lateral movement. Causing the carriage to lift raises the tool bar and disengages the braces from the support members.
