New Holland cx8070 in winter barley

[Andy R]

Hi All
Struggling to get a clean sample from our New Holland CX 8070 in winter barley.
Have tried all combinations of concave. sieve, fan speed and forward speed and still getting awns and trash in the sample. Have the de awning plates in
Any sensible comments greatly appreciated.

Perhaps not regarded as a sensible comment, but is it fit? The old boys used to say bugger off for a fortnights holiday when you think the barley is fit.

Don't know where you are @Andy R (there's a location bit you can fill in on your profile page so it shows up near your avatar) but I'm guessing you're rained off now. You might find that, when it dries out enough for you to get going again, it'll thrash a lot better.

Yeah as above usually if it's not clean it's not quite ready there's been many row's about that over the years and always been a clean sample a few days later after rain

We had the same when we started. Took the back de awning plates off and if improved a lot. Rain and then a dry spell will help too.

Close pre cleaner sieve until only clean grain goes through.

IMO a lot of problems are caused by not having enough wind. Try increasing it to the at least the max that the book recommends. Remember that closing sieves also reduces wind pressure and opening them increases it.
I’d recommend always using the max wind, then shutting the sieves to get the sample you want. Unless the crop is of excessively low bushel weight, that too much is being blown off the back. Only then should you reduce the fan speed.
But most of all, properly fit crops make life so much easier for any Combine. Having to use de-awning plates is not conducive to this.

I had a hell of a problem last year with our cx820 in barley, couldn't stop it going over the sieves, was crawling along to keep it in the tank. Was told on here last year that you need plenty of wind with these combines and it is the case, been running really high fan speed this year and keeping a better sample and less grain over the back that way. Think it's easy to block the sieves in barley and the grain goes over that way.

We are up in North Norfolk
Been cutting Flagon which is a new verity even our John Deer’s been struggling a bit

Thanks everyone for the advice hopefully this rain and then some better days should improve things also a bit more fiddling with settings should get it right before we finish winter barley and help with the spring barley roll on wheat

what do you call really high?

 

[Andy R]

what do you call really high?

More than I think is ok but the boss seems ok with it and this is my first season in a long time and combines have changed since I last drove them (I know the principles are the same from the very early machines) so may be I’m being a bit to fussy but crop from the top of the tank looks good but all the rubbish seems to gather at the window

Just over 1000 on the fan, seems wrong that high but was getting the desired results.

don't take to much notice of the sample by the window it's always looks bad there check in the trailer
