An agricultural implement configured to shift weight between a center toolbar and left and right wing sections. Each wing section includes inner and outer sections pivotally coupled about a horizontal axis. Left and right wing flex actuators pivot the outer wing sections with respect to the inner wing sections about the respective left and right horizontal axes. Each of the inner wing sections is pivotally coupled to the center toolbar about respective left and right vertical axis. The center toolbar section is supported by a center wheel assembly and distal ends of the left and right outer wing sections are supported by respective left and right wing wheel assemblies. A monitor is in signal communication with load sensors on each of the wheel assemblies and a fluid control system to actuate the wing flex actuators so the measured center wheel load approaches a center wheel target load.
