Patent ID: 8428831

Claim:
An assembly for facilitating steering of an agricultural implement linkable to a work vehicle in a field, the agricultural implement including a main frame and a connection joint for linking the main frame to the work vehicle so as to allow the agricultural implement to be towed through the field by the work vehicle along a path, the assembly comprising: at least a first ground-engaging wheel to engage a ground surface below the frame thereby supporting the frame above the ground surface; a positioning system for receiving positioning signals from a positioning source as the agricultural implement travels through the field, the positioning system determining current positions of the agricultural implement from the positioning signals as the agricultural implement travels in the field and a coverage area of the field based upon prior positioning signals, and the positioning system generating control signals, wherein each control signal is derived from a corresponding current position of the agricultural implement and the coverage area; and a steering cylinder connected to the first ground-engaging wheel and operatively connected to the positioning system to steer the first ground-engaging wheel based on the control signals thereby continually adjusting the path as the agricultural implement travels through the field to minimize the creation of a non-coverage area of the field.
