Keeping Ear Tips out of the sample.

Normally it’s OK from 750 to 1000 rpm.
We will try today in better stuff opening the sieve back up to 10 mm and using the drum to refine the sample. I think we will get a more consistent feed in a more inform crop so less light running and bad threshing.
It’s done the spring barley with 10mm lower sieve and high forward speed so it should also do the wheat at similar high forward speed without losses.
We have just been plagued with these damn tips in a manky bit.

Have you checked the drum / concave measurements, back to front, side to side?
Some varieties have always been a devil to get a clean sample though

On minimum setting it’s 8 mm at front 3 mm at back as per the traditional barley setting 5/16 at front 1/8 at back. It opens progressively from there.
I haven’t checked it for maybe 5 years but we only do about 150 acres a year.

A slight bend in a drum bar will also cause poorer threshing.

I never could get the tips off with my 1085 kept shutting the bottom sieves to put it back through returns but still no better I put it down to lack of a rethrasher mf 865 before it was a fantastic sample

you may be surprised how the settings are if you check, I remember being shocked when I ran a 975 and ended up fitting new bars and concave, but some crops you will always struggle

Avalon was a sod to thresh properly
It may be down to variety and year

Talking to claas ,man yesterday ,said a lot has not been really fit , bet stuff this week will go better , getting tips out has been hard this year ,
@flat ten had some 3 rd crop firefly done 4 .1/4 ton on silt ,1 st wheat on black only just scraped 4

Well we have opened the bottom sieve back up to 10mm and pushing her on fast. No significant returns but quite a few unthreshed tips in the tank. It’s a compromise we can live with. There isn’t really much other than shrivelled grain in the tips unfilled as the plant ran out of steam.
Makes you wonder what the bottom sieve is for though.
unloader auger belt now on its last legs. Keeps coming off.
And drum speed variator keeps losing speed and is extremely slow to adjust up again when operate the spool valve. Still going though. Limping on.

We have had trouble with tips since time immoral here. Dad always reckoned the ears never finish properly on this dry old sand.

Dad always runs quite a high drum speed, 1050-1100 and pushes on. This is the straw from yesterday.

Yes a higher drum speed would help. He’s right. Sod’s law we are now having trouble with variator. Creeps down and is incredibly slow to speed up when you operate the spool valve.

That's not a bad job to do, if you evgot the seals ready to go in its only an afternoons job.

Seals at the spool valve or the cylinder/piston in the variator pulley? would have thought if it was leaking at the variator pulley there would oil all over the belt? But it appears dry.

Variator pulley. Usually when they go it will spray a line of oil up onto the underside of the tank.
I don't know about the spool block seals, I've never had to interfer with them.....touch wood!

Thanks, I’ll have a look in the morning. It’s been detoriating over a couple of years. I found a loose accumulator in the pressure line under the tank and a slight leak. Tightened up, thought that was easy and I had cured it, but no.
I’m at 1050 on my TX 63

I stripped down the spool valve block in the spring as the traction variator would not reduce speed. Found rust and sediment stopping the spool valve from moving to position to allow dump back to tank. Didn’t replace the seals in the block but I believe a seal kit is available for the spool block from JD for a hundred or so. Complete new block 6 way or something about £5k from JD

It’s a compromise between smashing up good grain and getting it all out. Usually we are on 1000 plus for barley, 750 to 1000 for wheat. Crispin is a big soft wheat so I try to be gentle with it.
