B7800 stalled, can't start it (safety interlock ?)

posted this here but maybe this is a better location.

I stalled my Kubota B7800 this morning and the normal restart procedure isn't working. I imagine I tripped some safety interlock but I can't figure it out.

I had my tractor idling, neither PTO engaged, in low gear. I was on the ground next to it and wanted to back it up 12", so I reached over with one hand and depressed the "rear" speed control foot pedal.

The tractor moved backwards 1", then - because the engine RPMs were low, and the front wheels were in a rut, it stalled out.

OK, no big deal, it happens.

Hop on tractor.
* Turn key to off
* verify both PTOs are off
* gear selector to neutral
* 3PH lift/lower selector to neutral
* RPMs to middle
* butt in seat, so weight switch is engaged
* clutch fully depressed
* turn key to preheat, hold, then to start

nothing.

All the proper lights are on, but the starter doesn't crank at all. (which is why I think it's a safety feature).

I pulled out the manual and walked through the proper starting procedure, step by step, and I sure think I'm doing everything correctly.

My only hunch is that by stalling it out in a rut, I've maybe done something different than my usual dumb stuff.

Any insights or help? I'd love to unblock my driveway!

Thanks,

TJIC

Check the directional pedal to be sure it is centered. Might have stayed off center since you were pushing it gently with your hand...
