Abstract
An implement includes a frame having a main section and a wing section pivotally coupled to the main section. A row unit is mounted to the frame wing section to dispense a product to the ground surface. A weight transfer system transfers weight from the frame main section to the frame wing section to reduce the load carried by the main wheel assembly. A row unit downforce system applies a force on the row unit relative to the frame wing section. A pressure transducer measures the force applied by the row unit downforce system and generates a signal indicative of the applied force. A control system operates the weight transfer system in response to the signal from the pressure transducer to assist the row unit downforce system. The control system actuates the weight transfer system to apply an additional force on the frame wing section in response to the signal.
