ABSTRACT:
A drive sprocket includes a plurality of equispaced rollers which mesh with complementary shaped receptacles defined by surface portions of drive lugs of adjacent sections of a track. The surface portions of adjacent drive lugs leave a gap at the bottom of the receptacle defined thereby for permitting material such as mud or snow and the like to be pushed therethrough by the sprocket rollers. The axis of pins interconnecting adjacent track sections is aligned with the axis of a sprocket roller when the roller is located in the receptacle formed by the drive lugs of the adjacent track sections.
