This isn't intended to be a question thread but will hopefully help somebody in the future with the same issue I just got done dealing with.
Back in mid-November I was wrapping up the last of my mowing with my Kubota M7950 when it just up and quit on me in the field like the fuel was quickly shut off. I dragged it back to the shop and did some simple troubleshooting before assuming the worst (like the injection pump went south on me).
I then proceeded (struggled) to get the Rhino SE-10 off of the lifeless tractor and drag it onto my trailer for the drive to drop it off at the nearest Kubota dealer.
The service-shop called after a couple of days and said they'd found algae in the fuel system but they were able to clear the lines out and it was now running. And that they'd seen a few cases similar to this lately.
So I picked it up, topped off the fuel tank with some fresh fuel, doubled up my usual additive (Power service Diesel fuel supplement) and optimistically went back to mowing to try to finish that job up. It ran for about 2 hours then quit exactly the same way...So I dragged it back to my shop and started to work on it myself.
Long story short, I had to drain the two tractor tanks and disassemble and clean all of the fuel lines from the tank thru the seperator to the fuel pump and up to the fuel filter housing, put on a new fuel filter and buttoned everything back up. I then said some kind words to the tractor gods and hoped like heck I wasn't going to have to pull the tanks and have them boiled out.
I then emptied out all the fuel in my transfer tank and steam cleaned it out, and finished with a trip to the county hazardous waste drop-off. All told about 6-8 hours of time total.
Funny thing is, I always religously bought my red-fuel from the local co-op and added the appropriate additives. I did buy the tractor used 4 years ago so I suppose the bugs could have been there even before I got it...
So far, after about 8 hours in the field I don't seem to have any more issues (knock on wood).
So the moral of this long and sordid tale is that if you are troubleshooting a fuel issue, you may want to consider algae as a possible culprit.
But, before you end up facing what I just did and if you want to add a few more additives to your fuel arsenal, here is what you need:
- Power-Service Clear-diesel, Bio-Kleen, and the trusty standard supplement.
- and the Longer-Diesel-Life and Star-brite Water absorber just for good measure
- and a brand new golden-rod water-block fuel filter on your transfer tank
Hopefully this will be informative to some of the group out there as well as giving me a chance to repay a small portion of the great reference material I have found here...and share some misery all at the same time.
Good luck and stay safe out there,
Rex
