Someone please HELP ME. I’m about to lose my mind. I love/loved my little bx 25. I’ve had “Booty” since September 2014. He only has 259 hours on him. I’ve done all maintenance right on time and used Kubota stuff to do it with. Fast forward to a month ago. Instrument dash went blank. My original dealer closed, a new one opened up nearby. Called them, they came and picked up “Booty”. While there they said it was a fuse that caused Instrument panel to crash. Fixed. I also had the seat recall taken care of and my dented hood replaced under the insurance. “Booty” is returned home, I think everything is going great. Uh Oh. A week later the dash goes out again, after a few days they get back to me and tell me where the fuse is. Replace, seems OK. A week later I go to mow with the belly mower, my little tractor starts to buck a tiny bit, the tachometer rpms drop to zero. Tractor is still running. When I try to rive up the rpms it starts to try to cut off. Tachometer jump when starting, then drops to 0. No smoke at all. Call the dealer. They come get him. Guy that comes to get it drives it up on the trailer, it’s trying to cut off on him. I get a call a few days later. Service guy tells me a boot somewhere broke off and while spinning cut some wires, he rerouted and rewire, everything is fine, he’s coming home. That afternoon I get a call, Service guy said tractor kept trying to cut off when putting on trailer. Next day they call me and tell me that the Diesel Fuel smells like Gasoline. This is the problem. NO WAY, NO HOW. I buy all my Diesel from local Shell station. The only Diesel I’ve ever put in “Booty”. I have receipts from the beginning. Booty has never been off property, Booty has never been refilled by anyone but me. I go to Dealer. They have this Black tank on the ground with “My Diesel” in it and dip out some with this old beat up plastic pitcher. “See, it smells like Gas”. Me, well did you have gas in the vat? Duh. Now they change the fuel filters and put their diesel in “Booty”, he now still tries to cut off, and now white smoke is bellowing forth. So they send off the fuel injectors off, and tell me that two are not working. Today they install new injectors, nothing different happens. Now they tell me it a bad valve from having gas in the diesel and tractor needs new engine. I say, did you have my diesel tested and what was the results. Response was “NO”. We didn’t save any. I have called Kubota and I filed a complaint with the district service Representative. I did the test where you put a Styrofoam cup in some diesel and in a couple of hours it has any gas in it, it will melt a bit. Styrofoam cup intact. What is wrong with “Booty”. I don’t want my tractor to be sick.

Re: Someone help me PLEASE.

Kubota dashes from that range of bxs were horrible, moisture issues etc will need to be replaced but most likely has nothing to do with your running issue. If it only starts to die when you push the hst pedal you have an issue with your seat switch or opc wiring. If it starts to cut out when not moving it is most likely a fuel restriction could be fuel filters or something in your tank. Injectors in those engines rarely fail

Re: Someone help me PLEASE.

The first steps to restoring your tractor to good health is detachment. You must put aside your emotions, rise above, and be the master over your mechanical servant.

When machinery is assembled and provided for correctly, it must work!

Your task is to simplify and confirm that those requirements are being met.

You may choose to leave it to the specialists. The "doctors" over at the kubota service center. But remember, 1/2 of all the doctors graduated at the bottom half of their class.

First thing, is to get away from the "it could be electrical, or it could be mechanical, or it could be fuel".

Sounds to me like the service department is fishing, and using your bait!

New doctors and second opinions might be good ....

Re: Someone help me PLEASE.

Sounds like you need another dealer. A small amount t of gas should not hurt anything. Sounds like they are not sure what's wrong and yet are throwing parts at it, at your expence.

My first thought is an issue with one of your safety switches. Possibly a seat switch going faulty causing a hit and miss connection.

Fuel related is gonna cause pretty consistent issues, and a quick easy way to test for it, is a clean jug full of known clean diesel with the intake line for the fuel pump dropped into the jug. If you still have the running issue, then the issue is somewhere else. If the issue goes away, then drain and clean the fuel tank, refill with known good clean diesel.

The BX models have a known issue with the sending unit for the fuel gauge rusting out and causing clogs inside the fuel tank as well as the fuel filters.
