Combine barley separation TX34

Oh and there will be rectangular inspection plates on both sides of the combine to let you see into the concave, again in behind the front wheel area obviously. I'll send you a few photos from the manual if you want me too. You'll get the hang of her, we all had to learn.... usually from bitter experience haha

we have a drying floor and a large fan to dry it with. forcast looks changable all week and the week after, i just dont want to get stuck with a combine in the shed and an empty grain shed....tomorrow it depends on the app... some say its fine all day, some say thunderstorms at 1. depends who you believe.
I know the weather does not look special at the moment. You are doing better than us, we haven't cut anything.

well it was fully closed i think, so should that be adjusted? dealer is coming out some point to regas the AC, worth getting him to take a look and check adjustment on the concave?
Just because it says it’s closed in the cab doesn’t mean it necessarily is, it may have a lot of ware and be miles out!
There will be a measurement for the gap between the bars and the concave at the front and rear and usually some access plates either side. On mine you fully close the concave the measure 7mm at the front and 4mm at the rear.
This is on my Claas but you get the idea

Well on barley when it's completely ripe the heads should be drooped over and kinda hanging down, I just go by look. If the plant looks completely dead to me, I'll chance a bit with the combine to see what the moistures like

Alright. So must the straw be dry? or is it just a case of needing a bit of sun on it to get it to thrash properly? It was overcast to start the day, but then towards the evening it dried up and the sun came out.
it was wrapping around a little bit yes, so i assume that it was just too damp. Is that because of straw being damp? Please just treat me like an idiot on this because i know very little about the intricacies of combining.
There’s no shame in asking. Combining is a skill you get with experience ive driven one for 18 years and I still feel like a new boy at times often ring somebody up with more experience than me if i have a problem

well this is the first field and we have cut about 100 yards.... and we shouldnt really have done that! We did have the chap out to do the straw elevator chains as we found they were worn when a link went, he gave her a once over and couldnt find anything wrong.

very interesting. So i can take off an access panel at the side of the combine and check that distance with the concave at setting 1 and check its to within the spec, which i assume would be in either the operators manual or the dealer service manual, I do have both, though i dont really think the dealer service manual is much help, its instructions for the straw elevator chain were along the lines of: How to remove the chains, "step one, remove the chain, step 2, reinstall the chain". It kind of expects you to have a decent knowledge of working on combines already, and then just tells you the really complicated bits that are different between machines.

the heads are pointing almost directly downwards, and it looks dead. So i assume its just too wet.

Usually the operators manual will give the settings and adjustments, really all the settings should be checked as a pre season check over/service.

Never driven or had anything to do with a tx but sounds like something could be set wrong, we have a Cx so this may be of no use to you but we have a second drum/ rotary separator and you can change the speed of that, also you can open or close the concave under it, the other thing is we have toothed threshing plates for cereals or smooth ones for beans/rape that go in the bottom of the returns, if you were doing beans last and your tx has a similar set up then this needs checking, but others on here can tell you if the tx has these, only other thing is how wide is your bottom sieve, maybe try closing it and put more through the returns but be careful not to overload them also. But like others have said cant beat harvesting on a sunny warm day.

how can i tell if the returns are overloaded? I think the seives should be adjusted as we neglected to do this between beans and barley. we were more worried about getting it all off of the straw first! as far as i know all i can adjust the speed of is the drum and fan. The dealer we bought it from (graham holland if you know of them) set it all up for beans before it was delivered, as we said that was what we would be combining first. aparently a very good combine mechanic had checked over it, and it had had several new belts and parts fitted by them. i will check on the concave clearences tomorrow.

Your sieves will be far to wide if still set for beans, that will explain the un threshed heads in the sample. I’d sit down with the ops manual and have a good read, usually it will give some base line settings for each crop to start from and show how to adjust each part according.

yes i have a separate book for the settings. doesnt mention seive settings though, but that would explain the unthreshed heads yes. it doesnt explain the grain left on the straw though, which is what im more worried about. can fiddle with seives after thats sorted. but yes, i will have another read of the manual... might keep me from going and trying to combine it again!

damp straw will definitely carry grain over the back, and as had been said if it’s rapping around the auger it’s usually time to go home.

I'm guessing you will have a returns monitor in the cab along with sieve and straw walker losses, keep an eye on those, as Phil P said if your sieves are set for beans then that's half your problem, I havnt cut any barley this year yet but as a rough guide I would try 12/14mm top sieve 6/7mm bottom sieve and adjust from there.

There is a performance monitor which we had looked at as I couldn't get anything out of it. He said it might work but if it doesn't then there's not much you can do about it except replace the whole unit. We mill all our corn for meal so we don't mind getting some chaff in the tank. Also as its a big combine we can go slowly. Ill look at setting those seive settings next time we have a go, thanks.

Your monitors may yet come too life when you close your sieves, no problem hope it goes better when you go again.

Have ran 2 34's a few years ago now but found them to be very capable for there size,I would start with concave up tight,open it up a bit if it's skinning/splitting grains,1000rpm should be fine,top sieve 12-14mm,bottom 6-8mm,de awner plates in to start with,it should be able to run at least 3/kmh even with a 20ft head,if your barley looks like picture one it should be flying,up in Scotland 18% is very common to be cutting cereals so I wouldn't be concerned about that.
