Abstract

In accordance with an example embodiment, a work vehicle may include a chassis, a linkage, a work tool, first and second actuators connected to linkage, one or more sensors, and a controller. The work tool is movably connected to the chassis by the linkage and pivotally connected to the linkage about a base axis. The work tool includes a tip positioned at a forward end of the work tool, with a tip axis parallel to the base axis and passing through the tip. The one or more sensors are configured to provide one or more signals indicative of at least one of a position, velocity, and acceleration of the work tool. The controller is configured to actuate, based on the one or more signals, the first actuator and the second actuator to level the work tool by rotating the work tool about the tip axis.
