I am going on two seasons with my 485R and have had the best luck with this machine than any other make_model previous. Our dealer is excellent to work with and has a very knowledgable field crew and support staff, providing parts and service support virtually 24_7, especially during harvest season. Setting a twin rotor lexion is no problem. Its hybrid design, using both conventional cylinder and twin rotors, allows it to be very flexible in all crops and its capacity is tremedous. I run a 36' MacDon draper in beans and wheat and a 1230 cornhead. We are able to avg. day in day out in all conditions a ground speed of 5.5 mph. With such a consistant harvest speed our productivity level has increased to a level equitable and most times more than when running two 9610's. The APS system in the lexion allows the machine to work as easily in tough green conditions just as it does in easy to thresh dry conditions. Servicing the machines is very simply with very few daily grease points. The engine is extremely easy to work around if warranted and all fluid fill necks are conveniently located. Belt tensioning is also easy with simply ilder designs and belt trouble is virtually nill as long as adequate tension is maintained from proper servicing during the specified intervals. As for the tracks, I was never a big beliver in combine tracks until tried (and bought) a lexion with MTS. The tracks seem to allow for a much smoother ride in rough conditions, excellent (non-slip) traction and the engine runs at a lower % load due to the fact that the MTS doesn't have as high of rolling resistance caused by tire rutting in wet or dry conditions. By all means demo, you never know until you try it.
