摘要： An agricultural sprayer is disclosed, comprising a sprayer boom (1), an actuator (6a; 6b; 6c) and an operation controller (8). The sprayer boom (1) has a central boom section (5); a plurality of boom sections (2) provided in boom wings (3, 4) pivotably connected to the central boom section (5) on opposite sides of the central boom section (5), and a plurality of dispensing elements provided on the boom wings (3, 4) for dispensing a spraying material in operation. The actuator (6a; 6b; 6c) comprises an actuator element (7) which, for slope correction, can be moved between at least a retracted and an extended position, wherein an element length of the actuator element (7) is changed when the actuator element (7) is moved between the retracted and the extended position and wherein the actuator (6a; 6b; 6c) is configured, by adjusting the element length of the actuator element (7), to provide slope correction for the sprayer boom (1). The operation controller (8) is configured to receive a first request for slope correction for the sprayer boom (1), comprising moving the sprayer boom (1) to a first slope correction position; assign the first slope correction position of the sprayer boom (1) to a first element length of the actuator element (7); provide first slope correction control signals assigned to the first element length of the actuator element (7); and apply the first slope correction control signals to the actuator element (7), thereby, adjusting the element length of the actuator element (7) to the first element length for moving the sprayer boom (1) to the first slope correction position. Furthermore, a method for operating an agricultural sprayer is provided.
