Track assembly for farm implement

A farm implement comprising:

• a frame;
• a track assembly for assisting in moving the farm implement along a ground surface in a line of travel, wherein the track assembly includes:
• a camber arm coupled to the frame;
• a tilt arm coupled to the camber arm so as to be pivotable relative to the frame about a first axis parallel to the ground surface and perpendicular to the line of travel and pivotable relative to the camber arm about a second axis parallel to the line of travel;
• a rear idler wheel coupled to the tilt arm;
• a front idler wheel coupled to the tilt arm and positioned in front of the rear idler wheel along the line of travel;
• an alignment arm pivotally coupled to one of said tidler wheels so as to allow the pivotally-coupled idler wheel to pivot about a third axis that is vertical relative to the tilt arm;
• and
• a track belt looped around the front idler wheel and the rear idler wheel to make contact with the ground surface.
