System and method for controlling harvesting implement operation of an agricultural harvester based on tilt actuator force
A system for controlling harvesting implement operation of an agricultural harvester includes a fluid-driven actuator configured to adjust a position of a harvesting implement of the agricultural harvester relative to a feeder housing of the agricultural harvester.
