Were the feederchain and feederhouse issues on the cr970's issolated to the very early models or is it still an issue on the 9070's.

When did they solve the problem and how.

Currently looking at an 05 cr970 with 300sep hours. Any thoughts?
Thankyou

Why did you replace when you just broke a slat?

What year is your cr970 Andy and is there any truth to the problem of the chain jumping off the top sprockets?

Thanks everyone for the input

well, the slat caught inside and broke the chain too. so then it was chain time. at 800 hrs we thought that might be good insurance. When we had gone to look at the machine before we bought it we started it up and all of a sudden it went bang and the stonetrap popped open. out came the brace used for locking a Swathmaster pickup's suspension. So the feederchain got a little stress out of that as well.

When we had our macdon on the TR98 it would jump a cog almost daily. got a honeybee this year and never had a problem once. big slugs make the spring tensioned chain unhappy.

Did you run the deflectors in bottom corners of the feederhouse in both cases?
Seems like when material can enter the feederhouse right on the edges that
helps get straw between the chain and the sprocket allowing it to skip.
Always seems worse in barley to me and
I think it happens when reversing the feeder.
Solution: eliminate reversers!

We ran deflectors under our 1st macdon until the dealer said to take them out to try to get it to feed better. They are most likely somewhere on the yard, but I'm not sure where. No deflectors with the HB either and has not been an issue. The reverser setup isn't the problem on a TR, its those chains and weak-sauce sprocket tensioner mounts that twist up all the time. Solution, yes, no reverser. Or...Heavy pieces of channel iron. Haven't needed the reverser nearly as much this year since putting the HB on the front, however.

Basically, I think Macdon has a decent header now, but HB has had one for years already.

Hmm, digging out an old topic here but I demoed a 04 CR960 with 500 sep.hrs this week and had some feeder house noise issues.

Granted I was doing canola at 11-13% moisture, but it seemed like any time any kind of small lump would go through there was excessive clunking and banging coming from the feeder house area.
Was also running a TR99 on the same field with none of the feeder house noise like on the CR.

I will get the dealer to check it out before I consider buying it but it seems from this topic and others that there where some issues with the feeder chains.

The problem with early cr chains breaking is the slats putting pressure on the chain as it goes round the roller, if look at a late build cr, i think 07-08 onwards there is a cut out in the slat so wen it goes round it doesnt put pressure on the chain, so if u are breaking links take off all the slats an cut out abit out with an angle grinder, this should solve the breaking issue.
