Perhaps you should remove your "yellow-tinted glasses" and read my previous post again; - I said the lexion REMINDS me of a CTS, and I'm not sure "where you're going" with your boring statistical comparisons (which are listed in similar order from the brochure); - the electric worm gear concave positioning and concave adjustments seem to work fine, so why change it. I wouldn't consider myself to be a "diehard, colour-blind green guy" since I'm still "blessed" with owning a Gleaner C62, although I've noticed in almost EVERY post you've made that you're responses seem to have a very distinct "yellow-slant" to them; - could you possibly be affiliated with CAT or AGCOIJIJIJ Hmm!!! Before I get too "Catty" with my response (no pun intended),let me say that I stand by my previous post. Having owned AGCO product through the Allis Chalmers_Duetz_AGCO transition, I have learned that it does not pay to participate in a "test market", and with Cat's recent decision to clearly and abruptly exit the AG business, anyone buying a CAt_lexion_Challenger product is (to a certain degree) "chancing it"! Just ask any North American farmer who's owned a Claas; - in fact, ask me, because I owned a Dominator 106. I paid nearly "Deere price" for it, and I was credited "Belarus value" for it when I traded it in. The Dominator was an excellent, well engineered combine, but as owners we were left sitting when there dealer network and marketing initiatives collapsed. I will give credit where credit is due, however. You strongly believe in your product with the hopes that things will get better, and you sell your beliefs very hard! Deere doesn't have to sell hard; - they've built thier market share by producing quality equipment, giving great service and remaining fiscally responsible and stable throughout the years. Maybe CAT_AGCO will achieve this in the next 20 years, who knows!
