New to us loader, seems a little low on power, has a little more black smoke than I think it should. 2012 model, all new service, no codes. My thoughts are turbo, or are they just not a powerhouse?
I don't much about these machines as they came out after I quit the dealership. But I would check the basics, I know you said that it was just serviced but I'd start with the air cleaner make sure it isn't plugged for some reason.
We have the tool carrier model. It's no 950, but it will fill the bucket in the gravel pile no problem
