An earthworking implement (10) has a replaceable ground engaging tool (18) retained onto a tool mounting portion (16) of the implement by an elongated retainer (22, 114). The tool mounting portion (16) has an exterior surface (26) with a first retainer pocket (28) providing a first abutment surface (32) facing in a direction substantially away from the primary direction of travel (24). The ground engaging tool (18), in turn, has an interior surface (52) with a second retainer pocket (54) positionable in alignment with the first retainer pocket (28) and provides a second abutment surface (56) disposed in a generally spaced, diametrically opposing relationship to the first abutment surface (32). An elongated retainer (22, 114) is positionable within the retainer pockets (28, 54) to restrict the tool (18) from coming off the mounting portion (16) in the direction of the primary direction of travel (24).
