How do you know where to put the blank plates on the rotors? We have a 1997 CTS with rasp bars. We are going to be cutting wheat and beans again this year with it. Right now we are just trying to understand how to fine tune the machine.

Hopalong, what size concaves does your machine in it. Are all the wires installed in the concaves.

From my Lexion experience the blank plates on the rotors are to prevent the shoe from overloading. In dry conditions the crop gets chopped up more as it goes through the combine. the further to the end it is the finer it is, causing it to fall through the grates onto the shoe and may overload the shoe. To prevent this from happening one has to start putting blank plates from the rear on forward. The finest material is in the rear and needs to be pushed out the discharge, therefore the grates need to be covered there to keep it from falling onto the shoe. The dryer the conditions the more blank plates are needed.
On the newer Lexions this can be done with a button from the cab.

Pressuming this is a grain machine & not a rice machine. Start at the back of the grates leaving the loss monitors uncovered & continue forward for at least 2 full sections - sometimes go to 3 sections if it is really dry such as we have in Australia. Some years ago there was a company in Canada (I think) that made grate assemblies with adjustable covers - excellent idea. If, as you say, the Lexion have this facility via push button in the cab, that is what is needed.
