Abstract
A tower and wheel arm assembly for an implement frame includes a pair of identical single piece pivot castings which are selectively connectible at different locations along the frame and provide both wheel arm pivoting and a cylinder anchor tower pivoting. The wheel arm axle extends between the castings pivots within cylindrical cavities located in the castings. External cylindrical surfaces concentric with the cavities rotatably support a pair of tower plates which include circular openings received over the external cylindrical surfaces. Casting symmetry allows the same part to be used interchangeably for either the right-hand or left-hand support.
