I have loved the Lexion combines; they have the highest capacity by far, but we have just spent over $40,000 in parts alone on our 2 590R's in the last 150 hours. Both our machines have hit the 1200 hour range. Before the 1000 hour mark they ran fine. Before these combines we had JD 9650(which are no good either) and 8820's which one had 11,000 hours and the other 7800 hours. We baby our combines and always run at about 85% of capacity. Here is what has failed on the 2 590R's in the last 150 hours. Both main cylinder and rotor variables.
