Abstract
A supporting frame mounting a work implement, such as a post hole digger, is disclosed wherein the supporting frame is connected to a standard snow plow mount at the front of a truck. The supporting frame includes a fixed base member affixed to the snow plow mount and supporting a rotatable base portion by a slew bearing. The supporting frame further includes a double arm boom member pivotally connected to the rotatable base member and a single arm boom member pivotally connected to the double arm boom member to provide a compact nesting configuration for transport. The work implement is affixed to the single arm boom member by a pivot and a swivel to permit a self-seeking vertical orientation by gravity. A hydraulic system powers the pivotal movement of the boom members and the rotatable base member, as well as the operation of the work implement. The hydraulic operations are effected by manipulation of a pair of joy stick controllers that are pivotally movable between an upright transport position and a tilt-out operative position. Stability for the supporting frame is attained through a pair of opposing support legs pivotally connected to the fixed base member, the pivotal movement of which is effected through a ratchet mechanism. The extensible boom members and rotatable base member provide a great range of operation for the work implement from each resting position of the truck.
