    Abstract: A ground engaging tooth assembly for a cutting edge of a ground engaging implement may include an adapter and a ground engaging tip. The adapter may have a forward extending adapter nose having an inverted or reverse keystone-shaped contour, with the ground engaging tip having a nose cavity for receiving the adapter nose and exterior surfaces having complementary shapes to the adapter nose. The adapter nose and an adapter cavity of the tip may also be configured with complimentary surfaces that increase retention between the adapter nose and the tip when downward forces are applied to the tip. In other embodiments, the surfaces of the tip may include reliefs extending inwardly into the body of the tip to reduce weight and facilitate penetration of the tip into work material as wear material wears away from a front edge of the tip.

    Abstract translation: 用于地面接合工具的切割边缘的地面接合齿组件可以包括适配器和接地末端。 适配器可以具有向前延伸的适配器鼻部，其具有倒置或反向梯形轮廓，其中接地末端具有用于接收适配器鼻部的鼻腔和具有与适配器鼻部互补形状的外表面。 适配器鼻部和尖端的适配器腔也可以配置有互补表面，当向下的力施加到尖端时，该表面增加了适配器鼻部和尖端之间的保持力。 在其他实施例中，尖端的表面可以包括向内延伸到尖端的主体中的浮雕，以减小重量，并且当磨损材料远离尖端的前边缘时，便于将尖端穿透到工作材料中。

    Abstract: A tool bit includes a shank portion defining a longitudinal axis, a free end, and a perimeter, at least one anti-rotation feature on the perimeter extending to the free end, and a cross-hole defining a cross-hole axis along which the cross-hole extends through the shank portion. The tool bit also including a working portion extending downwardly axially from the shank portion. The working portion includes a rear region, a front working region defining a width with a midpoint, a first side region and a second side region. The first side region and the second side region define an angle of extension measured in a plane perpendicular to the longitudinal axis. The cross-hole axis pass through the width of the front working region when projected onto a plane perpendicular to the longitudinal axis.
