Abstract
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 one hydraulic threshold condition is satisfied as indicated by a hydraulic pressure sensor. Attachment decoupling is prevented unless the pressure sensor outputs an electrical signal that indicates that the attachment is safely positioned (e.g., full-extend or full-curl). In one example, this is indicated with the attachment positioning cylinder is pressurized above a select threshold as indicated by a pressure sensor.
