2014 Kubota BX1870 Tractor - Engine bogging down and stalling.

[Shane Hanna]

2014 Kubota, I cleaned fuel tank, changed fuel filter, changed air filter, replaced fuel pump, added new diesel fuel (just a little to test), I am baffled at why this is happening, but I am positive someone else will know. I appreciate any suggestions, thanks in advance. It does it at idle, full throttle, seems to be worse under load, but it also seems very random. Here is a video of how it is acting:

I believe the BX tractors have (2) fuel filters inline. Did you replace both of them? It sure sounds like a fuel delivery issue.

Many yrs ago I owned a M4900 that the engine bogged down even after changing fuel filter, cleaning water separator screen. Local Kubota dealer service manager advised me to check for clogged screen in fuel control valve in water separator housing. I removed retaining screw then removed control valve & located the tiny screen & it was clogged. Cleaned screen & bogging problem was solved.

Also check and see if there is a hose kinked ...

Fuel supply issue..
Does your machine have a supply pump.??
I think I remember seeing something about a 2nd filter under the tractor..??
