Abstract
A method and system for automated operation of a work vehicle comprises a boom having a first end and a second end opposite the first end. A first hydraulic cylinder is associated with the boom. A first sensor detects a boom angle of a boom with respect to a support near the first end. An attachment is coupled to the second end of the boom. A second sensor detects an attachment angle of attachment with respect to the boom. A second cylinder is associated with the attachment. A switch accepts a command to enter a ready position state from another position state. A controller controls the first hydraulic cylinder to attain a boom angle within the target boom angular range and for controlling the second cylinder to attain an attachment angle within a target attachment angular range associated with the ready position state in response to the command.
