Abstract: A tool for inserting and withdrawing a peg in the ground comprises a body (20, 60, 101) having an internal space (22, 61, 110), and a peg puller which includes a peg engaging means (30, 74, 120) for engagement with a peg in the ground. An impact member (26a, 71, 123) is located within and is movable within the internal space in the body. A hammer head (10a, 51, 105) is provided at one end of the body. The body further includes a strike area (25, 65, 128) within the internal space and located so that the impact member strikes against the strike area at one limit of movement thereof inside the internal space. The peg puller further includes a connecting portion (36, 73, 121) extending from the impact member to the peg engaging means so that when the impact member strikes against the strike area, a shock load is transferred through the connecting portion to the peg engaging means to thereby apply a pulling force to the peg.
