<p>A tip (16) of a tooth assembly (10) for a ground engaging implement or bucket is constructed with a necked down portion (70) to provide the tip (16) with a reduced cross-section sufficient to cause the tip (16) to fail at the necked down portion (70) when the tip (16) is subjected to a sufficiently large vertical load in order to prevent the breakage of the adapter (14). The tip (16) also has side ears (58, 60) that diverge away from the side surface (36) of their respective ear pocket (26, 27). This construction prevents the distal ends (62) of the ears (26, 27) from contacting the side surfaces (36) when the tip (16) experiences high side or lateral loads. The tip body (40) is also constructed such that its cross-sectional area does not substantially increase between the leading cutting edge (66) and the rearward end portion (42) so as to maintain tip sharpness.</p> |
