I use rough re thrashers in oats and barley, but have used the smooth ones in bly as well. Book settings ok except find canola to be quite different depending on conditions. After you have used that wrench a couple of times you tend error on the side of higher cylinder speed and tighter concaves.

When we had CX combines the book setting for barley we’re close. We ran a fast cylinder for oats and closed the concave a lot more then book said. Canola is a tricky one as it can split it. Slowing down or opening up the cyl/concave sometimes makes it worse as it returns more and that’s where the cracking comes from.

Book is close on most except canola. If straight cutting nice dry stuff then the book is fine.

Canola
Drum 550-650
Concave dry 1", tough 3/4, wet 1/2
Fan 600-700
Upper sieve 3/8-7/16
Lower sieve 3/16-1/4
Rotor speed slow, grate open
Smooth rethresher cover

Do yourself a favor, start the season with fresh chopper knives. Second year flip them. Replace them after 2 years. The chopper loves to bridge.

I'm not sure If the 8.8 has this issue or not, but the traction drive belt from the 8090 pulled significantly better than the standard 8080 belt. Big difference in tough canola swath.

Arnold innovations hyd reverser wrench is worth the money if you're doing alot of canola.

The engine access door in the grain tank can leak canola onto your drive belts. Little bit of gorilla/duct tape action before starting canola can save you a headache.
