1. A method of controlling a towed agricultural implement, comprising:
receiving an input indicative of a main depth setting indicative of a position of main depth control system wheels;
generating a main depth control signal based on the main depth setting, to control a set of main depth actuators that each actuate a corresponding main depth control system wheel to the position relative to the frame indicated by the main depth setting;
accessing, based on the main depth setting, a predefined correlation indicator, indicative of a predefined correlation between the position of the main depth control system wheels relative to the frame, indicated by the main depth setting, and a position of a stabilizer wheel relative to the frame;
identifying a stabilizer setting, indicative of the position of the stabilizer wheel relative to the frame, based on the predefined correlation indicator;
actuating an isolation valve to a closed position in which the set of main depth actuators are fluidically isolated from a stabilizer actuator that actuates the stabilizer wheel;
automatically generating a first stabilizer control signal based on the identified stabilizer setting, to control the stabilizer actuator, independently of the main depth actuators, to actuate the stabilizer wheel to the position of the stabilizer wheel relative to the frame indicated by the identified stabilizer setting;
receiving a change input indicative of a change to the position of the stabilizer wheel relative to the frame;
generating a second stabilizer control signal based on the change input to control the stabilizer actuator to actuate the stabilizer wheel; and
modifying, based on the change input, the predefined correlation indicator to change the predefined correlation to a predefined correlation between the position of the main depth control system wheels relative to the frame, indicated by the main depth setting and the changed position of the stabilizer wheel relative to the frame indicated by the change input.
