Abstract
An agricultural implement is provided that includes a hitch assembly configured to couple the agricultural implement to a tow vehicle. The agricultural implement also includes a carrier frame pivotally coupled to the hitch assembly by a main pivot joint such that the main pivot joint resists substantially all lateral loads between the carrier frame and the hitch assembly. The agricultural implement further includes a pair of wheel assemblies each rotatably coupled to the carrier frame by a respective knuckle pivot joint, and an actuator assembly configured to rotate each wheel assembly about the respective knuckle pivot joint while the agricultural implement is in both a working and transport position.
