1. A method for coordinating grading operations of first and second grading implements of respective first and second work vehicles during a single grading pass of the first and second work vehicles, the method comprising:
processing, by a first controller onboard the first work vehicle, a first grade control signal;
processing, by a second controller onboard the second work vehicle, a second grade control signal;
orienting, by a first actuator of the first work vehicle, the first grading implement with respect to the first work vehicle according to the first grade control signal; and
orienting, by a second actuator of the second work vehicle, the second grading implement with respect to the second work vehicle according to the second grade control signal;
wherein the second grade control signal is based, at least in part, on the first grade control signal to coordinate the orientation of the first grading implement with respect to the second grading implement along the grading pass.
