1. A farm implement comprising:
left and right track assemblies for assisting in moving the farm implement along a ground surface in a line of travel, wherein each track assembly comprises:
a camber arm mounted in a camber arm housing, such that the camber arm permits the camber arm housing to pivot about a first axis perpendicular to the line of travel and a second axis parallel to the line of travel;
wherein the camber arm housing has a front end and a back end, and further has upper connection points on both the front end and back end and lower pivot points on both the front end and back end;
a first mounting bracket coupled to the upper connection point on the front end;
a second mounting bracket coupled to the upper connection point on the back end;
a first set arm having a first idler wheel set mounted on one end and a first bogie wheel set mounted on another end, wherein the first set arm is pivotably coupled to the first mounting bracket such that the first idler wheel set and first bogie wheel set are movable in opposing vertical directions;
a second set arm having a second idler wheel set mounted on one end and a second bogie wheel set mounted on another end, wherein the second set arm is pivotably coupled to the second mounting bracket, such that the second idler wheel set and second bogie wheel set are movable in opposing vertical directions;
