A ground-engaging track system includes a center tread idler having an inner surface defining an idler axis of rotation, and an outer tread surface. The ground-engaging track system further includes a track contacted by the idler between parallel track chains and defining a track pitch dimension. The outer tread surface defines an outer diameter dimension, and a ratio of the track pitch dimension to the outer diameter dimension is between 28% and 37%. The outer diameter dimension may be one of the outer diameters of Table 1. The idler and track contact during service at fixed bushing-idler contact locations so as to bias wearing away material of the idler to form pockets imparting a sprocketed configuration to the idler during service.
