Claim Text:
1. A ground engaging tool system comprising: a ground engaging tip having a coupling portion and a ground engaging portion, the ground engaging portion and the coupling portion extending along a longitudinal axis, the coupling portion including an interior surface defining a coupler pocket having an opening, the interior surface having a base wall, a first side wall, a second side wall a first coupler face wall and a second coupler face wall, the first side wall and the second side wall in spaced relationship to each other along a lateral axis, the lateral axis being perpendicular to the longitudinal axis, the first side wall and the second side wall each extending longitudinally from the base wall to the opening of the coupler pocket, each of the first side wall and the second side wall defining a retention orifice, the retention orifices defining a retention axis therebetween, and the first coupler face wall and the second coupler face wall in spaced relationship to each other along a normal axis, the normal axis being perpendicular to the longitudinal axis and the lateral axis, the first coupler face wall and the second coupler face wall each extending longitudinally from the base wall and extending laterally between the first side wall and the second side wall, wherein the first coupler face wall and the second coupler face wall each has a planar portion and a curved portion, the planar portion being disposed adjacent to the base wall, and the curved portion adjacent the opening of the coupler pocket; a coupler pivotally connected to the ground engaging tip such that the ground engaging tip is movable with respect to the coupler over a range of travel about the retention axis between a nominal position and a maximum rotated pitch position, the coupler including a mounting nose, the mounting nose including a first exterior face surface and a second exterior face surface in opposing relationship to the first exterior face surface, the mounting nose disposed within the coupler pocket such that the first exterior face surface and the second exterior face surface are respectively adjacent the first coupler face wall and the second coupler face wall of the ground engaging tip; and wherein, over the range of travel between the nominal position and the maximum rotated pitch position, the curved portion of both the first coupler face wall and the second coupler face wall are in non-contacting, spaced relationship with the coupler.
