Odd stalling problem

plaindave · Mar 2, 2005

I just got back in from moving snow and I had an odd problem with my B7800. I had just dumped a load with the FEL backed up and was about to take another bite on the pile when the tractor stalled out. If I didn't know better I'd say I ran out of fuel. Tractor started right up again and I finished up real quick and headed in.

Fuel gauge reads at 1/2 tank and I used a ruler to check and see that there was still fuel there. Can't imagine it was water in the fuel, would have been more of a problem. I wasn't on an incline. Tractor was warmed up and running fine at about 1800RPM. I wasn't lugging the engine down and stalling it that way.

I have no clue. Any guesses or suggestions? This has me a little concerned - just isn't something that should happen.

The only thing I can think of is a fuel filter problem. I have had ice in a fuel filter block off my supply before . It would slow me down and then return to normal. Drove me nuts for awhile .

I would replace the fuel filter and add a container of water additive to the fuel system to try and chase the water out .

I agree with BigAl. Give his solution a try.

Are you sure that you didn't raise up from the seat enough for the seat disengage to shut it down? Maybe you were sitting too far forward on the seat?

Gave rides to a Japanese family. Put mom on without moving the seat forward. It quit on her twice. Figured it out later what happened.

Good morning

I agree with the previous posters. If it is not the seat switch that one mentioned, then it is most likely fuel.

When I first got my tractor, a diesel mechanic friend of mine mentioned that the one thing that I should pay constant attention to is fuel, especially in a cold climate. He suggested that I use a good diesel additive and clean the bowl and change the filter every 50 hours.

So far with that advice, all has been well.

Good luck

Seat switch would be my guesstimate also.

I also agree with AL.... I'm thinking ice in a filter or line.

A good running diesel just doesn't stall.. not like a gass tractor.. etc.

Ditto. I have to leave my tractor out in the winter and I always flip the seat forward. If I don't do a good job scraping the snow/ice from the bottom of the seat and the top of the seat frame, sometimes just a little shift in the seat can stall me out.

Thanks. I thought about water in the fuel, but didn't see any evidence of it in the bowl of the fuel filter. But ice in a line does make sense. In winter I don't keep any fuel on hand except what's in the tractor (a full tank lasts me all winter for moving snow). I'm at less than half a tank so I'll fill it up tonight and put in an additive while I'm at it.

I'm pretty sure I had myself planted in the seat while working, but I will check the safety switch too.

Appreciate the ideas. I was not too happy last night. But it would have been worse had it not restarted and I had to tow it back to the shed.

Hi

Just one more point because you mentioned it in your last post.
I always try to keep my tank full, especially in the winter. I am sure that keeps down the condensation and the possibility of freezing a fuel line.
