Abstract

An excavation system is disclosed for a machine having a work tool. The excavation system may have at least one sensor to generate a signal indicative of a load exerted on the work tool. The excavation system may also have a lift actuator and a tilt actuator. The excavation system may also have a controller configured to detect engagement of the work tool with a material pile based the signal. The controller may operate the work tool to load the work tool with an amount of material. The controller may determine whether loading of the work tool has been completed. The controller may lift the work tool when the loading has been completed. The controller may also operate the tilt actuator to shake the work tool. Additionally, the controller may cause the machine to withdraw from the material pile after shaking the work tool.
