Retention system for a ground-engaging tool

摘要

A retention system for a ground-engaging tool includes a pin. The pin may include a shaft extending along a longitudinal axis of the pin; a radial projection extending from a first end of the shaft; and a head disposed at a second end of the shaft, the head having a non-circular axial cross-section. The system may also include a retainer collar. The collar may include an annular wall surrounding a recess configured to receive the first end of the shaft; an axial slot in an inner surface of the annular wall, the axial slot extending from a first end of the annular wall inward and being configured to receive the radial projection; and a circumferential slot connected to the axial slot in the inner surface of the annular wall, the circumferential slot being configured to receive the radial projection of the pin.
