I've put a few hours on it the last few days and I'm impressed, it's a smooth running machine and very manuveravble. It makes loads of torque and at 1600rpms never grunts doing dirt work. The loaded rears have made a huge difference in traction, haven't even needed the mfwd yet. I take it these new 1 series tractors aren't popular yet, so maybe this thread will help any who may be interested in the future. The crdi fuel system is Delphi, and it has a small turbo. The diesel engine itself is made by LS as I understand it. It is very smooth and quiet, I'm sure somewhat due to the crdi. The exhaust treatment is described as a doc/dpf combination, maybe a newer type technology; I guess time will tell how it does. I am quite satisfied with the tractor so far and I will update periodically with my experience.
The only negative I have is there is a small leak on the left side of the transmission where a side plate is. My dealer said no problem it will be fixed. I'll update on that when I get it adressed.
Oh and the tractor is very dusty at the moment hahaha, better outside the cab than in my nose! I'm praying for rain though way too dry here.
