Windrower is guidance ready.  Have a Ag Leader 7500 receiver, TerraStar X unlock and subscription.  800 monitor and Ag Leader SCM.  We entered all the measurements and got through most of the calibrations.  We couldn't get calibrations finished, because it kept saying that the operator was moving the steering wheel. We tried everything we could think of. Header engaged and lowered, different mph, etc.  Is there something in the way of Ag Leader not playing nice with the Massey side?  Ag Leader salesman is stumped and Massey tech guy is "busy".    Says "machine error-check for low engine speed" on AG Leader monitor code list.
