Abstract
An earthworking implement adapted to normally engage the ground in a primary direction of travel has a replaceable ground engaging tool retained onto a tool mounting portion of the implement by an elongated retainer. The tool mounting portion has an exterior surface with a first retainer pocket providing a first abutment surface facing in a direction substantially away from the primary direction of travel. The ground engaging tool, in turn, has an interior surface with a second retainer pocket positionable in alignment with the first retainer pocket and provides a second abutment surface disposed in a generally spaced, diametrically opposing relationship to the first abutment surface. An elongated retainer is positionable within the retainer pockets and has a pair of opposite solid end portions oriented to abut the first and second abutment surfaces such that the end portions restrict the tool from coming off the mounting portion in the direction of the primary direction of travel.
