A few weeks ago we took delivery of our first Claas, a new 980 and have ran it about 10 hours since then chopping rye. We've been impressed overall with the machine, with one exception, cab noise. Compared to our Krone 1100 that we still have, the Claas cab noise is excessively loud, an annoying whine. So much so, that to hold a conversation with a rider sitting 18" away, one has to talk rather loudly, whereas in the Krone, one can almost literally whisper and hold a conversation. I must say that I was very disappointed with that part of the chopper. The rest of the machine, looks like Claas has Krone beat, but not in the area of the cab, in our opinion. The door rattles when it latches shut and doesn't latch nicely. Visibility is poorer looking out front and definitely to the right and left. Without starting a brand war, is this poor cab normal for a Claas machine?

Alot of the claas's I've driven have had excessively loud cabs, and I drive a John Deere..

The Claas combines we had were very noisy as well

Check the plastic out side the cab on the bottom. Make sure it is not touching the window causing the whine.

Its sometimes personal preference, sometimes the machine. Either way I doubt you will get them to pay much to meet your expectations on something like this. You could rip the cab apart and install a product like dynamat to help deaden the sound. Many S series Deere combine owners had to do this. If theres room you can add some insulation between the outside wall and panel also.

Without looking at one I would assume door has some adjustment. If its ratttling it may only be catching the first latch. If it isn't shutting tightly that could be a large part of your cab noise also.

We had a 2011 Claas 940 on hire a couple of weeks ago and I was very surprised how loud it was in the cab. Our old Case 8790 was considerably quieter and the 2004 Claas 900 we now have is a LOT quieter.

My ears were ringing for a couple of days after driving the 940. Not really acceptable for a 'new' machine IMHO.

I have heard its something to do with the new style drum, when there is stalky grass going through them (ie your rye grass) they hit a certain frequency that is a bit of a white noise. I have heard of a few foragers round here going back to the dealers to have more soundproofing fitted so it might be worth talking to yours, as with your door rattling, the cabs are near air tight, if you open window at the other side and give a good slam, they a lot better.

I agree with the whine, we have a deere, kemper it is nearly silent in the cab, put the pick up front on and you'd think there was no soundproofing, amazing difference.

Thanks for the responses, guys. Hopefully it wil be more satisfactory in corn next month.

Small drum kempers are very noisy though it seems.
