2950 WON'T RUN

SKYBOW · Dec 22, 2008

I have a JD 2950 82 HP diesel. I needed to move a bit of snow out of the drive his AM and ran into a problem. I have a block heater and a magnetic oilpan heater on it. I got it to start OK and let it warm up a bit. Seemed the hydrallics were a bit slow but it is 5 degrees outside and I attributed it to that. I went to the end of the driveway and backed the tractor across the county road. Right in the middle of the raodway the tractor stopped dead. I couldn't get it started. Got the truck and put the jumper cables on it. The tractor started right up. I let it run while I disconnted the jumpers and moved the truck out of the way. I climbed back on the tractor and it died as soon as I let out the clutch. Seems the throttle has little effect on the RPM's. Could the fuel be gelled-I used some additive before it got cold. Bad injectors? I jumped it again, threw the cables off and drove it toward the barn. It died about halfway there. Runs normal for about 2 minutes and then just dies. Suggestions??? Thanks

Does it have an electric shut off ? as it seems electric related as it starts and runs with the jumper cables on. Battery may be bad ?

Change the fuel filter.

Sounds like the fuel is gelled to me. Put in some of that 911 additive and it will thaw right out.

I never experienced gelled fuel before due to family getting all #1 diesel. But I got some nonwinterized #2 fuel at a gas station and it gelled on me. For a while Tractor would pass enough fuel it would run but only at lower speeds. Then it would just idle. Then not at all. Pulled the sediment bowl and it was just like a thick jelly. Went and got some 911, filled the bowl with it, put the rest in the tank and it ran like it was summer.

If it was gelled, it would not restart.

Oh yes can restart with gelled fuel. It will run til starved but after sitting for 5 minutes the heat from the engine unjells the fuel and it will start and run til it sucks in gelled fuel again.

fuels gelled on my 4320 that does some snow plowing i fired it up in the winter at -40 and she started and ran then started fartina round like it would rev halfway then idle then rev up then idle then almost die then revup again so i let it run for a while and since the diesel gets pumped around alot in the system it warmed the fuel up and ran good after that snowplowing i went to town got some kleeflo antigel threw that in and never had another problem and a few years back the 4320 would rev up then then slowly idle down and after about an hour it would snow down so much it'd die so i took her to JD and they ripped the injector pump apart and found a small piece of foam in there took it out and ran fine so not that this ir your problem just telling you something if it does happen to you

Probably a frozen filter. When Deere changed over to the single Stanadyne glass-box filters, they got a freeze problem. The rectangular filter traps water on the bottom. One cold night, it turns to a block of ice, and then - the tractor will start and quit, over and over.

You're supposed to open the water-drain on that filter once in awhile to prevent this from happening.

We used to have an entire fleet of rental Deere machines that would freeze like that. We'd pull the filters off and let them thaw out, drain, and re-install.

[b:63de9ac9dc]Oh yes it can![/b:63de9ac9dc] Mine did! In fact I restarted it many times to get home ( I was 3-4 Miles from home). It would die, I sit a few minutes, restart and go till it dies again. I did have to wait for it to restart though. Maybe the engine heat helped.

I would say gelled fuel, if not that, do these particular engines have an electric shutoff? They can give a man fits as well if the alternator isn't charging correctly or bad batteries.

If the fuel gells it will be done starting.Gelled fuel is a solid not a liquid.Most likely you have ice in the fuel filter or line thats not completely closed off.It just runs until its out of fuel,then sets a little bit and more fuel runs through,them it runs out again.The only cure for gelled fuel is get it inside of a building or put a tarp around it or something and a heater of some sort to get the solid fuel liquid again,or Power Service or something in enough of a quantity that it will melt down gelled fuel,then new filters with Power Service in them,and it might run.Im not sure if you mix number one or kerosene in gelled fuel if it will liquify or not,I dont think it will.You might just change the filter and fix it.Always a good idea in the winter time to have a spare filter for a diesel.To see gelled fuel put a little number 2 in a glass jar and put it in the deep freeze.Once it gells you will see why it wouldnt run.Looks like frozen ice tea.Wont go though a fuel line like that.

Exactly right...

The only thing I'd add, from misery I've had with one of my Ford's is that sometimes the tank strainer will freeze up and restrict the flow on that end. I've got one with an electric lift pump that will run for a couple minutes like that on the fuel in the filter, then quit.

I blow the lines back to the tank, change the filter and go. A tank cleaning may ultimately be in order.
