Engine cutting out...Kubota B7800

[jodebg]

I was operating my Kubota B7800 yesterday and noticed that the engine briefly cut out.

Once as I was backing up, and once while I was beginning to accelerate up a small grade with a load.

Can there be a problem with the seat switch?

Not sure if the former owner bypassed the seat switch?

This could easily be the seat switch. I had a similar issue and ended up bypassing it to resolve.

How would I wire this to bypass the switch?

 

[MikeInEburg]

Find the wires under seat, pull them off and tape them up.

water in fuel?

last time you change fuel filter?

Put a new fuel filter in 13 months ago/75 hours on the new filter.

Should I replace it?

Depends on how dirty the fuel and/or the tank is. Make sure the tank strainer is not clogged as well as the filter and fuel lines. Make sure the fuel line connections are tight and the lines are not damaged or pinched.

I am new to tractors. Can you tell me where to find the tank strainer? Can it be removed to inspect and clean?

There is no fuel shut off that I can see. The manual says to remove the clear cover and the fuel will stop flowing.
Is this the correct way?

My friend's wife had that problem with a used BX. Turned out she wasn't heavy enough for the safety switch under the seat. Turned out there are two plates which work as spacers for the sensor. I removed one plate. No more problem.

Not to long ago another B7800 owner had the same problem post here on TBN...try a search.
I'm thinking in the lines of bad fuel or crap in tank,maybe drain fuel flush tank and lines new fuel filter.

If you have any doubt, replace the fuel filter. It's just too cheap compared to the frustration of an un-diagnosed trouble. When you have old filter off, make sure you get a good flow from the tank.

On my B7800, if I lean too much one way or the other it will cut out. Seat switch issue. Search with the easiest answers first before you start taking things apart.

Same with my B7800. Now if it starts to cut out, I just shift my weight in the seat and all is good.

Good idea to bypass the switch?

I always like to keep my stuff original if possible so I would leave the switch alone unless it really bothered me. If I did by-pass it I would do it with a simple jumper wire so it could easily be reversed. Just my two cents on this.

I 'bypassed' the seat switch on my cub cadet lawn tractor. Actually it was more of a 'got around the problem' with the switch as it has about 6 wires and I couldn't figure which one to jump.

So I pulled the switch out of it's clip on the seat, pressed the 'button' to the closed position and wrapped some tape around it to keep it in the closed position.

Fortunately my Mahindra doesn't have the stupid switch.

I'll bet one of my pitiful paychecks it's the seat switch. I bypassed mine too.
