1. A drive shaft connection assembly for an auger connection post, said assembly including: a first coupler having a top end, a bottom end and a perimeter wall being attached to and extending between said top and bottom ends; said top end having an upper well therein configured for receiving and releasably engaging a drive shaft; a second coupler having an upper end, a lower end and a peripheral wall extending between said upper and lower ends, a post being attached to and extending upwardly from said upper end; an auger connector being attached to and extending downwardly from said lower end; said bottom end having a lower well extending upwardly therein to removably receive said post, said post being rotatable with respect to said first coupler to selectively engage or disengage said first coupler; a sleeve being slidably mounted on said perimeter wall, said sleeve being removably slidable over said peripheral wall such that said sleeve engages each of said first and second couplers to prevent said first coupler from rotating with respect to said second coupler, wherein said sleeve is disengageable from said second coupler to allow rotation of said post with respect to said first coupler to release said post from said lower well; and wherein said post has a notch therein extending around a periphery of said post, a disc being defined between said notch and a terminal end of said post, said disc having a cut out therein such that an outer surface of said disc parallel to a longitudinal axis of said post includes an arcuate section and a planar section to facilitate passage of a pin from said notch to an area beyond said terminal end, a second pin receiver extending through said lower well and through said perimeter wall, a lower pin being positioned in said second pin receiver, said post being rotatable to engage or disengage from said lower pin.
