Rotors never changed.When lexion came with new roto grates in 2019 and they are no good .
Did those units all got upgraded by dealer or could there still be units around if dealer just sold them as .
Are 2020 rotors same as 2022 ?
what else is different?
NO!I would think that running maybe a combination of the two grate styles might be a good choice. With the addition of cover plates, it might be better in a wider variety of conditions.
Nobody wants to know why?!Those finger grates had a very special talent, they could increase shoe loss AND increase rotor loss at the same time.
Quite an accomplishment really.
I assume all their new stuff gets tested hard in Germany? Are their crops lighter with straw that the rotor grate issue got past initial testing? I assumed Euro crops had tons of straw.Nobody wants to know why?!
To swag how that is even possible, the flooding shoe part is easy, greater grate open area.
As to rotor loss, that requires a study of the both the shape of the fingers and their positioning.
The fingers were not flat on top, they were dished with a rise at the tip causing them to throw grain back into the crop mat.
The old and now same new raised “bump“ wire grates are much more likely to send grain to the sides down to the pan
They were also staggered rows of fingers which may have increased grain reentry to crop mat.
Lacking the multitude of testing equipment I would like to think Claas has that is my swag.
If they have such equipment however that does not explain how this junk ever saw the light of production day.
Nor the straight paddle impeller.
Nor the 1 to 1 impeller drive.
Nor the primary auger drive belt.
All fixed now but still…
Not just Germany, protos are tested in many areas.I assume all their new stuff gets tested hard in Germany? Are their crops lighter with straw that the rotor grate issue got past initial testing? I assumed Euro crops had tons of straw.
Remember my first ride in ‘75 in a New Holland TR70, the first combine with axial threshing, no crosswise components to stir dust forward and the total lack of feeder entry dust was pretty impressive. Granted, with a pickup header.Ive also heard the new fan on the feeder house is not all that it’s cracked up to be (looked to be really bad with soybeans). Is this true? Why can they not figure that one out?
My sons 8700 is in the low 300 sn and my 8700 is in the high 300 sn. I assumed that they would both have the new “good “ rotor grates but neither do . Was there a recall to install the new style ones?
I do not know how this was handled but don’t think the word ”recall” or auto update applies.My sons 8700 is in the low 300 sn and my 8700 is in the high 300 sn. I assumed that they would both have the new “good “ rotor grates but neither do . Was there a recall to install the new style ones?
