Abstract
A thumb for an excavator includes a base with an inner end adapted to be connected to an excavator arm and an outer end, wherein the outer end of the base includes a body mount structure. A thumb body is releasably connected to the base. The body includes an outer working portion, an inner tail portion, and a coupling or pivot portion located between the working portion and the tail portion. The coupling portion of the body is engaged with the body mount structure of the base, and the tail portion of the body is releasably secured or captured to the base so that the body is located in an operative position for use of its working portion. The tail portion of the body includes first and second spaced-apart tail members. The tail portion of the body and the base include respective mating portions that are engaged with each other when the body is installed in its operative position on the base, and forces are transferred from the body to the base through these mating portions to minimize shear forces acting on the fasteners.
