An agricultural system, comprising: an agricultural harvester having a frame; a spout having an outlet end and being movably mounted relative to the frame; a spout actuator configured to drive movement of the spout relative to the frame based on a spout actuator control signal; harvesting functionality, mounted to the frame, configured to engage material from a field and to deliver the material through the outlet end of the spout as the agricultural harvester moves through the field in a direction of travel; a turn identifier configured to identify a location of a turn forward of the agricultural harvester in the direction of travel and to generate a turn location indicator indicative of the location of the turn; a speed detector configured to detect a speed of the agricultural harvester and generates a speed indicator indicative of the detected speed; a position compensation control system configured to generate spout position compensation information for controlling the spout actuator based on the turn location indicator and the speed indicator, the position compensation control system configured to send the spout position compensation information to the spout position controller prior to the agricultural harvester executing the turn; and a spout position controller configured to generate the spout actuator control signal to control the spout actuator based on the spout position compensation information; characterized in that the turn identifier comprises a turn angle identifier configured to identify a characteristic indicative of an angle of the turn and generates a turn angle indicator based on the angle of the turn, the position compensation control system configured to generate the spout position compensation information for controlling the spout actuator based on the turn angle indicator. an agricultural harvester having a frame; a spout having an outlet end and being movably mounted relative to the frame; a spout actuator configured to drive movement of the spout relative to the frame based on a spout actuator control signal; harvesting functionality, mounted to the frame, configured to engage material from a field and to deliver the material through the outlet end of the spout as the agricultural harvester moves through the field in a direction of travel; a turn identifier configured to identify a location of a turn forward of the agricultural harvester in the direction of travel and to generate a turn location indicator indicative of the location of the turn; a speed detector configured to detect a speed of the agricultural harvester and generates a speed indicator indicative of the detected speed; a position compensation control system configured to generate spout position compensation information for controlling the spout actuator based on the turn location indicator and the speed indicator, the position compensation control system configured to send the spout position compensation information to the spout position controller prior to the agricultural harvester executing the turn; and a spout position controller configured to generate the spout actuator control signal to control the spout actuator based on the spout position compensation information; characterized in that the turn identifier comprises a turn angle identifier configured to identify a characteristic indicative of an angle of the turn and generates a turn angle indicator based on the angle of the turn, the position compensation control system configured to generate the spout position compensation information for controlling the spout actuator based on the turn angle indicator.
