It's working good. We harvest wheat, canola, peas and lentils. We use less fuel per day it seems and we rarely see the rotor speed drop more than 20 or 30 rpm. The only problem we've had is that we started having trouble breaking separator grates since we installed the rotor. I think the paddles are too close to the grates but Kuchar is sending us some new grates and they are spaced further from the rotor. We also installed the Kuchar feed accelerator and haven't plugged it once yet this year.
