Overshot loader for autonomous operation

A linkage assembly for an autonomous overshot loader, comprising:

• a boom having a first end pivotally connected to a frame and oriented substantially centered with and parallel to a longitudinal center portion of the frame;
• a stick having a first end pivotally connected to a second end of the boom;
• and
• a work implement pivotally connected to a second end of the stick.

An overshot loader for autonomous operation, comprising:

• a set of ground engaging members;
• a frame attached to the set of ground engaging members;
• a boom having a first end pivotally connected to the frame and oriented substantially centered with and parallel to a longitudinal center portion of the frame;
• a stick having a first end pivotally connected to a second end of the boom;
• a work implement pivotally connected to a second end of the stick;
• and
• at least one control link having a first end pivotally connected to the frame and a second end pivotally connected to the stick;
• wherein the frame defines a ground link of a first four bar linkage, the boom defines a power link of the first four bar linkage, a portion of the stick from a boom-to-stick connection point to a control link-to-stick connection point defines a coupler link of the first four bar linkage, and the control link defines a control link of the first four bar linkage.
