I cut peas, canola, wheat and barley. The cts combines are exceptionally good in barley, very good in wheat, average in peas and slightly below average in canola. The more straw you put into the machine the better it is compared to a walker machine. In very dry brittle canola straw the cleaning system can overload and slow the machine down. In tougher, green stemmed canola, the machine can process it better and it is actually better than a walker machine. In peas it is comparable to a walker machine for output and cracks, but poorer than a case-ih 2388 with a specialty rotor. On a whole harvest it is very impressive. It cut my threshing hours by 30% when I first switched from a 9600 to a cts. The biggest problem with the CTS, is that now that the STS is out, their is not much advertising out on them and most people don't know a lot about them. In my area (western canada) I think they are best buy in used combines right now (capacity versus price).
