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 position based on a first linear position of a first movable member associated with the first hydraulic cylinder. An attachment is coupled to the second end of the boom. A second hydraulic cylinder is associated with the attachment. A second sensor detects an attachment position based on a second linear position of a second movable member associated with the second hydraulic cylinder. A switch accepts a command to move to or enter a preset position state from another position state. A controller controls the first hydraulic cylinder to attain a target boom position and for controlling the second cylinder to attain a target attachment position associated with the preset position state in response to the command.
