Patent ID: 8327950

Claim:
An excavation apparatus, comprising: a) a base structure mountable to a vehicle, and defining lateral, longitudinal and vertical directions; b) a first supporting member pivotally coupled to the base structure, and pivotable about a pivot axis that is generally parallel to the lateral direction between a retracted position and an advanced position; c) a second supporting member rotatably coupled to the first supporting member; and d) a rotary spindle supported by the second supporting member, the spindle extending lengthwise along a cutting axis and rotatable thereabout for driving a cutting element, wherein, when the first supporting member is in the advanced position, the second supporting member is rotatable about a rotation axis that is generally parallel to the longitudinal direction, and the second supporting member is rotatable between a stowed position in which the cutting axis is generally parallel to the lateral direction and a deployed position in which the cutting axis is generally parallel to the vertical direction.
