I didn’t get mine installed at harvest last year. New to me machine and everything was too busy going theu everything else I didn’t want to start a project. Will have them in for this year assuming we raise a crop this year. Terribly dry.I would look hard at a smaller pulley change at rear rotor drive on flat belt (i think this is applicable on your model, not sure aabout 8000's. A machine shop can fix a pulley easier than 7500$ gearbox.
How effective was the keystock on the grates for you?
Went through some old Profi magazine testing of the 770 in 2011.

0.31 to 0.52% loss. Huh.
At an 8 hour total of 84.48 t/hr.
So...capacity wise was anything gained in 10 years?
Not in losses.
Perhaps in fuel use, an 8900 last fall while peaking at 120 t/hr while drinking up to 110 l/hr of fuel so 0.95 l/t vs 1.2 l/t on the 2011 test.
But 1% loss in the 2020 test.
But wildly far from a same field/same time comparo.
Probably a 1.0 to 0.6 or 0.5 G/MOG ratio.That wheat crop was only 41 to 55 cm tall and only 20-30 cm was going through the combine. Wow, a 41 cm high wheat crop here is probably not even worth harvesting. No wonder they set all those ridiculously high production records in Europe with combines.
I haven’t harvested oats in 55 years when everything was swathed.How do oats harvest compared to wheat...straight cut only here? Would like to try oats but never have.
For some reason that 8900 only a has the 15 cube hopper, the 18 with higher sides and vertical fill auger as long as tracks and an auto greaser are also ordered on NA units.Definitely envious of that fat auger and big hopper.
