An attachment control system includes an electrical control system and hydraulic control system. The electrical control system interfaces with the hydraulic control system to ensure that attachment decoupling in response to operator electrical control can occur only when at least two different hydraulic threshold conditions are satisfied. In one example, decoupling is prevented unless the attachment is safely positioned (e.g., full curl) in response to operator manipulation of a joystick or other attachment positioning device. This can be detected, for example, when the hydraulic system has an overall operating pressure at or above a first threshold and a joystick pilot pressure at or above a second threshold.
