I have a new b2650 25 hrs on yesterday when I was operating it noticed lost of power especially when I put the strain on. Blue smoke from exhaust and knocking noise. I taught maybe water in fuel drained tank put new fuel in cleaned the filter but still the same. Cracked the 3 injector lines one at a time while it was idling the first and second got a rough idle but number 3 never got that rough idle but did spray out bit fuel
engine idle rough and knocks

What do you mean when you say you "cleaned" the filter? I'm not familiar with your unit but are you sure it's a serviceable fuel filter? If it's not, it needs to be replaced.

Swap the injector w the 1 furthest away from it.. just to see if it follows the injector.
If it does.. u found the problem..
If it doesnt.. it could be the pump..
or u might have a fuel FEED problem.. enough fuel to run 2 instead of 3..

If, as you stated, NEW with 25 hours, don't mess with it but call the dealer.
You should be seeing an error code.

Check the coolant level in the radiator, not just looking at the surge tank. Hopefully it is full.
DO NOT REMOVE AN INJECTOR or move it to another hole!!!!!!!!!
Call your dealer.
Thanks for all the replies I took it to the dealer today they said its injector problem left it there till they get it sorted out should hear back soon if they have the parts in stock.
Believe it or not, you can do the opposite, diesel in gas tank and the gas motor will run. Not good but will run. Did that to my riding lawnmower. She was a real pig and smoked but ran.YEAH what they said call the dealer dont muck about with it!!!! And another thing, someone mentioned are you SURE someone didnt dump gas in the tank? It does happen,, dont ask,
Tractor still at the dealer no call today soon has I get it back will let you know the what the problem was
Well finally got my b2650 back from the Kubota dealership after being there for little over 2 weeks. The problem was a fuel injector was bad the one that is closest to the operator. Used it for about 5 hrs yesterday and been working great
I think I may have messed the injector up myself. I put fuel in the tractor that was bad had water in it. Reason I know after I got it back from the dealer used it for about 20 hours no problems. Then I decided to put the other fuel that I had outside in a can the winter got about half gone and stated doing the same losing power and knocking so I drained it out and got fresh fuel and added sea foam and new fuel filter let it idle for about 10 minutes and been working perfect since. Oh and the glass bowl that the filter was in had lot of dirty s___t in it and the filter was brown colour
