My 4310 won't start.

I turn the key and the glow plug lights up, then goes off like it should. I then turn the key to the start position and nothing happens.

The battery is relatively new and I took it to the Kubota dealer and they checked it and it's got plenty of cranking amps.

I'm pretty sure it's a interlock somewhere.

Any help would be appreciated.

TIA

There are several safety switches (seat, clutch,HST pedal, PTO lever).

Find the one that is not letting it start and fix it.

You can try to hold the key in the start position and move levers or pedals one at a time to see if it will start cranking. If that happens then that is probably the switch to repair or replace.

There are only two safety switches for the start sequence. That is the clutch switch and the PTO switch. The PTO is disengaged correct? You are depressing the clutch fully correct? It has to be as far as it will go for it to start. Other than that it s the same stuff, ign. switch, relay, starter and associated wiring.\
