Our is a 1989 1660 with the the large wires, and

sieves for corn. We are running the rotor about 920 rpm. the fan and the sieves are finicky we can get the grain to clean up but then throw out the back. then we adjust just slightly and dirty the grain and have very little on the ground. A happy medium is not found after 1 day of trying. We are cutting about 90 bushel wheat that is running between 13.0 and 14.0 percent.

Unfortnuately the guy that knew our combine's every nut and bolt (an expert by far) did not write much of anything down over the last 15 years so, I am running on the tidbits I picked up from him. Can't call him and ask him either.

The other thing that crossed our minds is that maybe she knows her master is not here anymore!

Any advice is appricated!
