Kubota B2320 shutting off while mowing

[M Allen]

My Kubota B2320 tractor has been shutting off while mowing. It will shut off and then start right back up. Will do this several times during a 2 hour mowing. Then I can use it to mow for 2 or 3 hours a few days later and it will run fine. Anyone have any idea what might be wrong?

If it's only doing this while mowing I would suspect a short in the seat safety switch.

Actually tractor does it when in use, not just when mowing. Doesn't happen every time I use it, will run just fine for a few weeks and then it will shut off 3-4 times while using.

Although others may disagree Kubota's are pretty rock solid and basic. That's why I will always have one. If mine acts up it's usually a stupid safety switch somewhere. To name some:

Seat safety switch.
Hydro pedal switch.
PTO safety switch.

It depends how it is shutting down. If it's an instant kill like turning off the ignition switch most likely it is a safety switch. If it's sputtering, engine missing, or losing power before shutting down that would suggest more a fuel or air delivery problem.
