Abstract
An agricultural implement is provided that includes a hitch assembly configured to couple the agricultural implement to a tow vehicle, and a carrier frame pivotally coupled to the hitch assembly. The agricultural implement also includes a pair of wheel assemblies each rotatably coupled to the carrier frame by a respective pivot joint. The agricultural implement further includes an actuator assembly configured to rotate each wheel assembly about the respective pivot joint in a first direction by applying a first torque, and to rotate each wheel assembly about the respective pivot joint in a second direction, opposite the first direction, by applying a second torque. A magnitude of the first torque and a magnitude of the second torque are substantially equal.
