I'm a couple minute drive west of you so my varieties and harvest conditions will be different. But what other changes did you make when you installed the covers? Changes to the settings I mean?
I run 3 gordens and keystock grates. Well, now I run my own home made helical grates, and Loewen helical concaves, but...before that I ran keystocks on everything and covers over the front 3 sections of straight bar concaves.
I slowed the rotor with the covers as there was no need to grind the wheat out when you now give it a chance to rub out. If you're still going to run the rotor fast, you need to push the machine and keep it full. The faster the rotor, the smaller the smaller the window for error is.
I imagine in your location you run the header on the ground? Probably tought o get enough material to keep it full? May have to rethink your settings a bit to compensate for the reduced material load.
Just my 2, IMO, etc.
