Question about Kubota Garden
Acted like I turned the key off or the seat kill switch turned it off. Not that and has plenty of fuel. Don't know where to start looking I am not a mechanic.
Tracking down fuel problems.
Do your self a favor, leave the gas cap off and turn the outlet air on your compressor down below 20 psi. If the tank is nearly full you will blow gas out of the tank.Do this outside if possible; at the very least you need a well ventilated area. After blowing air from the air filter back to the tank, you may have to reverse the process and pressurize the tank to get the fuel started.I place my hand over the open tank and hold the air hose between the joint of my thumb and forefinger to seal the tank, and then squeeze the trigger.Once you have a good fuel flow out the line to the filter, put on a FRESH FILTER. Try cranking the engine. If it still does not start move on to the fuel pump and carburetor
NOTE: Connect a volt meter across the two battery posts. If battery voltage drops below 9 volts when cranking or while the engine is running, the fuel cut off solenoid will not function. That means the engine will not start or will die soon after starting. So check your battery voltage before, during, and after cranking. If the battery voltage is good before but drops below 9 volts while cranking this is generally a sign the battery has one or more bad cells. Replace the battery. If the battery is in fact good, and the voltage is still dropping, you may have a bad starter motor which is drawing too much amperage.
If you find this fuel checkup does not solve the problem, repost your question with updated info and I will walk you through the next step.Tracking down a spark problem; yes, your problem could involve the coil. (Not as likely as fuel)

Try removing fuel bowl under carb and cleaning it. Junk and condensation can collect there. I had same problem. Did that and problem fixed.

On later models there are possibly three safety switches, one under the seat, one for the blade engage mechanism or blade clutch so the blades don't turn when the mower is started, and a neutral safety switch to make sure the mower is in neutral before it starts.

You have 3 safety switches located on the tractor, any one of which can cause the tractor to not crank over.
I assume the deck lever is not engaged, you are sitting in the seat and you push the clutch down when trying to start?
Start by lifting the seat and disconnecting the seat switch, push the clutch in and try to start.
Start there and we'll go from there.

SOURCE: Hi, my ST 30 Kubota
Hi, if it blew black smoke overreved and then was stopped suddenly, most likely then you have broken one or more "Rings" i would expect.
To do anything with these units, one simply must obtain a shop or service manual, one cannot service nor repair without the reference contained in the manual, not to mention the parts numbers, needed to obtain spare parts too.
Also inside these manuals, ate all the relevant troubleshooting steps that you need to take to isolate and then repair your problem.
The first thing to check, is the throttle make sure it is working OK, it may simply have been stuck, and simply need, lube, & a few good opening and closing of the throttle a number of times, then try starting up again, a little high revving and black smoke, can be Ok if just in the initial startup.... but if it is throttle jammed wide open, well then no.. however sometimes a motor will cough up black smoke for a bit, as it starts, it sort of "Clears it's throat" so to speak.. this may/should settle down once it all warms up... but generally as related, it means that the Oil is able to get by the rings, and up into the combustion chamber, and hence the black smoke, usually indicating worn, or broken rings.. which need to be checked.

the starter dims the lights noticeably when activated the starter is the culprit.
If it got stuck and ran with the engine the bearing will cease and the starter
will not turn. Dry bendix and or bearings will prevent starter to swing. If the
rotor is touching the field coils it will short and will not turn.
