I Have a cx 8070 which I love. I can't help you with the canola, barley thing, I have only harvested Different grass seeds with it. As far as servicing, It is a very easy machine to maintain on a daily basis. very few daily grease zerks , Very nice and quiet and comfortable to operate . I have been running case ih for years but this machine blows my 2188s away. Sometimes I think there is too much electronic stuff on them but everything is goin that way more and more and it is very handy. I will never buy another red machine after having this CX8070.(just my opinion) for what its worth)
I don't like changing the Engine oil filter from inside the grain tank,I think thats stupid . I like the rear window in the cab but when you open to clean it , it gets dirt and dust all over inside. Little minor dislikes like all machines have but when it comes to operation The best combine i have ever run. I even had a deere salesman admit he could not compete with these yellow machines. I will say that this is all in grass seed production . New holland has really taken a foothold the last 4 years in a green dominated area. A very large farm to the north of me (25000 plus acres) runs NH in grass, wheat and clover. I'm told they love them too.
