The mark consists of a three-dimensional recognizable configuration of the non-functional aspects of a center pivot irrigation system's pivot point, containing four pivot legs bolted to the base of the pivot point, the trusses connecting those pivot legs and the riser pipe within the trussed pivot legs. The mark consists of a series of four trusses that are mounted on four sides to the outside of four pivot legs that connect to the base and surround the riser pipe, together with four trusses that connect, one from each of the four pivot legs, to the riser pipe. The trusses connecting the pivot legs to the riser pipe are likewise bolted on the outside of the pivot legs. The trusses connecting the pivot legs form hollow acute angle trapezoids that are symmetrical on all four sides, while the trusses connecting the pivot legs to the riser pipe form two symmetrical triangles facing each other. Color is not claimed as a feature of the mark.
