Welger problem

[Dave6170]

Trying to bale winter barley straw today. The baler almost immediately jams the rotor, packing straw up between the flights hanging down at the back. Hardly any straw makes it into the chamber.

never had this problem before

Looks like you have the teardrop bar installed in the chamber,normally helps but try taking it out.

Just done that. Try and see

Baler worked perfectly after I took that bar out. Will I ever need to put it back in? Got silage to bale next.

That bar is a mystery,used to come bolted to the drawbar,only put in for dry crops
Then on the later ones they were installed from new,can’t remember ever taking one out.
Now the Kuhn I have it’s bolted to the side of the baler,haven’t needed it yet.

I've never had to take that bar out yet and I've ran welger since 2003. Obviously helped you tho

Baler is back jamming again. It tries to pull the straw back through between the plastic strip above the flights and the first roller. Then the roller starts jumping the chain

Straw is a bit soft but rain is forecast. Which is probably the problem.

Is it when you start a bale ?

Yes. It was working perfect yesterday then it just started doing it all of a sudden. Assumed it was when it got damp

I had the same in dagly spring barley , had 2 drop a gear to let it start the bale

I was just crawling to get it to start. Immediately jams

We've ran Welgars since the 90s and like you I've never taken one out yet, and I'd say we've baled everything imaginable.

Is it trying to pull it through where the bar was removed from?

 

[Dave6170]

Yes

Is it trying to pull it through where the bar was removed from?

 

[Dave6170]

I ll try it again tomorrow with the bar back in.

Is the bar straight enough?

 

[Dave6170]

Is the bar straight enough?

Yeah it’s fine

 

[Dave6170]

Put the bar back in yesterday. Made 150 of barley straw faultlessly.
Did notice that some of the flights at the back of the rotor have splayed out now. Wil have to take it out and try to straighten them.

Looks like it's not tuning the straw at the start, but slipping on the rollers. it happens now and again with different straw types, especially when it's hot and dry. Not easily resolved, they did a mixture of sand a resin to brush onto the rollers to gain more grip, but it was a compromise that was not a great success.
I think the reason it works OK sometimes is the straw will be a little damper.

That’s what they did on early RP12s,not heard of that happening on a later one with ribbed rollers.
