Its labor day weekend so I can't call in our normal kubota tech to look at our tractor so just looking for ideas about our tractor.
We have a 2018 m5-111. I was driving home from one of our hay fields and the tractor began to lose power figured i was just in to high of a gear lowered into next gear and it still didn't pick up rpms to normal levels. Finally was climbing a decent hill and the power gave out shifted down to low one and then it stalled. Tried to turn it over and it would crank but not fire up. Didn't notice any smoking when it was bogging down.

Towed it home, checked fuel supply line, no water in the separator, plenty of fuel being delivered to the filter and seemingly enough coming out to the injectors.
No codes on the display.
Any thoughts?
Thanks

Sounds like typical fuel starvation. Make sure the fuel shutoff solenoid is opening.

See if the air filter is clogged with dust.

See if there is a screen in front of the radiator that is covered with hay and pollen that would cause it to overheat.

You might be right on a fuel issue, but this is a common rail engine there is no fuel shutoff solenoid.
A fuel issue should also be setting a code.

The computer should have registered a code if it was air issue or an over heat issue.
