1. A track assembly for assisting in moving a farm implement along a ground surface in a line of travel, the track assembly comprising:
a tilt arm comprising front and rear ends;
a camber arm coupled to the tilt arm such that the camber arm permits the tilt arm to pivot about a first axis perpendicular to the line of travel and a second axis parallel to the line of travel; and
an elastic member;
wherein the camber arm is located between the front and rear ends of the tilt arm and the elastic member is connected between the camber arm and the tilt arm to allow for camber rotation and suspension.
