Ground Engaging Machine Having Articulation Hitch, And Method |
摘要 |
A ground engaging machine includes a first and a second frame unit, and an articulation hitch coupling together the first and second frame units. The articulation hitch includes a pin, a first and a second bearing positioned about the pin, and abutting a first and a second axial side of an annular protrusion of a hitch plate in one of the first and second frame units. A clamping mechanism of the articulation hitch clamps the first and second bearings between first and second clamping components, such that they are preloaded against the annular protrusion.
