We don’t know how big a bed he has on it

yield of 8.5t/acre
header width - 20 feet

surely you mean 8.5 tonne / ha ?

 

[Exfarmer]

assuming you mean 8.5 tonne / Ha then you are achieving 24.5 tonne an hour at 3 MPH
idk the straw is damp or the crop not so fit I think you will struggle to achieve that much more with a walker especially if there is a lot of straw
perhaps I am wrong

 

[Claus]

Oh yeah. Thanks for the correction. Wrong.

Any walker machine will struggle to get very high outputs unless the crop is very fit and the straw very dry and preferably cut as high as possible.
When I ran an 865 we thought 15-16 TPH in Barley was fair going and 20 in Wheat. But we used to cut for one customer who had huge crops due to his soil and style of farming where I have seen us pushing up to 40TPH as he would never let us near the crop until it was absolutely 100% fit and dry. Used to work well for us as he had a couple of hundred acres and we always cut it 2 weeks after we had finished everything else.
The 865 had beaters up the elevator and most of the separation happened before the drum in a fit crop

Had a 750 with beaters in elevator trunk I thought same

You'll get losses, try pushing on harder, the losses used to be high at lower speed, the around 4-6kmh would be the optimal, you can watch them go up and then drop as you fill it properly.
From memory wheat was fan flat out, RS tight, drum about 1000, sieves I'm struggling to remember but probably 12mm on top, 8 on bottom, but could be wrong on them
They had good output in good going.

good advice, but if crop is fit it may be smashing the straw up badly, then you need to open up the drum. Is the straw smashed and is any grain left in the heads?

The straw is almost not smashed. There is no grain in the heads.
The concave is in position 6 (9/6mm). Drum speed 1050rpm.
35mm rotary separator concave. Turnovers - 900rpm.

Where are your losses?
Sieves or walkers?
Should only be walkers, I had a job to get losses over the sieves.
It could be you need to open the rs and slow it down, it could be causing losses rather than reducing them.
Are the losses actual losses?
Or just the monitors showing them?
They're adjustable for different seeds and sensitivity.

 

[Claus]

The main part of the losses was behind the straw walkers. Losses were reduced to an acceptable level when I lowered the damper a little past RS.

Open the drum go faster, open it till you find just the very odd one then go faster again

 

[Claus]

Good. What settings do you use when threshing sunflowers? (drum/concave, wind, sieves)

 

[Exfarmer]

Drum wide open slowed right up.
Wind as slow as you can as it will all blow over, cant remember the openings, do you not have a book

I can look at the sieve openings tomorrow in system Datavision. Do these recommendations work well on sunflowers? The concave will be grain standard.

More important by far in sunflowers are the correct fingers and reel. Standard header will struggle. How many acres are you cutting!

 

[Exfarmer]

Where are you?

We have a header Optigep Optisun 870

 

[Claus]

How many acres are you cutting!

865 acres in cutting
I'm from Ukraine

You have my respect .
I hope the Russians leave your country soon.
Good luck with your harvest.

 

[Claus]

Thanks for the support and good words.
We, too, are waiting for our victory and the end of the war.
As for the harvest, it has been raining for 2.5 weeks. It is not possible to go out into the field to sow winter wheat and thresh sunflowers. Although sunflower was treated with drones today (desiccant) - 175 hectares.
