First Claim
Patent Images
1. 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 idler 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.
