The lexion corn head is by far the superior header. It is built stout, the way a corn head should be, without any ridiculous lite-weight cantilever design like a Deere. Each row unit of the lexion cornhead is supported from the front and the rear for greater reliability. The lexion row units also use knife rollers as standard with four knives per roller, that actually meet parallel to each other during operation for amore agressive chopping of stalks, reducing butt shelling and reducing the overall amount of plant material entering into the comine, they simply make the header and combine work more efficiently. All other brands of corn heads, except the old 10 series CaseIh corn heads, use over lapping knife rollers like fluted rollers (because it's cheap, common design and components to the fluted rollers). Overlapping knife rollers require more power (and turn into fluted rolls when worn),do more butt shelling = header loss and cause more plant material to enter into the combine causing the combine to be under a much greater load than necessary. lexion knife rollers are extremely hardened and last years (excessive wear is directly related to conditions). lexion is also the only mfg. to offer a very simple a highly accurate row sensing guidance system, which is very handy for keeping the combine and header on the row in down corn (just run the header under the down crop and all it needs is an inch or so to guide the combine).
