Patent ID: 8342255

Claim:
An agricultural implement, comprising: a hitch assembly configured to couple the agricultural implement to a tow vehicle; a carrier frame coupled to the hitch assembly; first and second wheel assemblies each rotatably coupled to the carrier frame by a respective pivot joint; at least one actuator configured to rotate the wheel assemblies about the respective pivot joints in a first direction by applying a first torque, and to rotate the wheel assemblies about the respective pivot joints in a second direction, opposite the first direction, by applying a second torque, wherein a magnitude of the first torque and a magnitude of the second torque are substantially equal, wherein the at least one actuator comprises a first actuator coupled to the first wheel assembly, and a second actuator coupled to the second wheel assembly; a tie rod extending between the first wheel assembly and the second wheel assembly, wherein the tie rod is configured to transfer torque between the pair of wheel assemblies, and wherein the tie rod and the at least one actuator are coupled to a first side of each wheel assembly forward of the respective pivot joint along a direction of travel; and at least one wheel rotatably coupled to a second side of each wheel assembly, opposite the first side, rearward of the respective pivot joint along the direction of travel.
