Abstract

An adaptable control system for the efficient use of different implement attachments for a work vehicle is disclosed. The work vehicle has an actuator for attachment and operation of different implements. The actuator is controlled by a control unit. The control unit has an input coupled to a user operated control device. The control unit is coupled to the actuator and activates the actuator in response to the user operated control device. An attachable implement such as a loader bucket is attached to the actuator. An implement data input such as a card slot is coupled to the processor. A portable data storage device, such as a data card, corresponding with the specific implement is inserted in the data input. The data storage device transmits instruction data relating to the specific implement to the implement data input. The controller operates the actuator in accordance to the data read from the data storage device. Alteratively a sensor may read identification data from an identification indicator on the implement attachment. The controller then selects corresponding instruction data from a memory device.
