have driven lexions for 4 yrs and also used to work as a combine mechanic for ClAAS. In my opinion they are the most reliable easy to operate machines I have ever had the pleasure to drive or work on. If there are any specific questions about servicing or operating please ask. As for the ClAAS back up, I can not speek for your nearest dealer, but ClAAS is a very strong well run company. The lexion Combine is one of the best selling high capacity machines around the world.
