AN IN-GROUND IMBEDDED PEG EXTRACTOR ARRANGEMENT AND A METHOD OF EXTRACTING A PEG IMBEDDED WITHIN THE GROUND
An in-ground imbedded peg extractor arrangement for extracting a peg imbedded within the ground including a spring within the main body and a pair of stop members at each end of the spring. A rod having a hook member adapted to hook and provide leverage about an end of a peg imbedded within the ground to be extracted such that a user driven upward movement on the longitudinal main body translates to an applied upward force on the spring from an extended rested position to a retracted stored energy position wherein the retracted stored energy position of the spring is recognizable by a noise and/or vibration made between impacting stop members whereby upon recognition of the abutment noise and/or vibration prompts a subsequent withdrawal of user driven upward movement of the longitudinal main body which then expresses stored energy in the spring to release a pushing force up upon the peg imbedded in the ground so as to assist in extraction of the peg.
