Claim 10:
11. A ground-engaging track system comprising:
a track roller frame;
a ground-engaging track having a first track chain and a second track chain, each including a plurality of track links, and a plurality of track pins each defining a longitudinal axis and coupling the first track chain and the second track chain together;
the track links each including an outboard link strap and an inboard link strap;
the track pins each including a first pin end extending through and supported for rotation in a respective outboard link strap, relative to the respective outboard link strap, in a respective one of the plurality of track links in the first track chain, a second pin end extending through and supported for rotation in a respective outboard link strap, relative to the respective outboard link strap, in a respective one of the plurality of track links in the second track chain, and a center section extending from the first pin end to the second pin end;
a track guiding space extends between the first track chain and the second track chain;
the center section of each of the track pins including an enlarged diameter, relative to the first pin end and the second pin end, positioned in part within inboard link straps in a different one of the plurality of track links in each of the first track chain and the second track chain, and forming an outer wear surface exposed to the track guiding space; and
