ABSTRACT:
An apparatus includes a shaft that has proximal and distal end portions. The shaft includes spaced grip covers conjoined about an outer surface thereof and is provided with a centrally registered sleeve formed therein. An arcuately shaped plow section is affixed to the distal end portion and includes a heel support that has an arcuately shaped top surface for assisting to maintain the plow section registered along a horizontal plane. The plow section further includes fastening members spaced along the bottom edge for removing the bottom edge to be sharpened or replaced. The apparatus further includes a mechanism for pivoting the plow section between alternate radial paths during operating conditions. A mechanism is included for automatically biasing the plow section to an equilibrium position after the plow section is biased to a pivoted position.
