Starter Relay

My L4310F is not starting, when I turn key, Starter Relay will Click, I’m greener than a green horn, but my hypothesis is the Starter Relay is Bad, All Help is Appreciated

Try jumping the tractor off of your car or truck. Many times the battery will have enough energy left in it to cause the solenoid to click, but not enough to turn over the engine. Use a good pair of jumper cables, not some wimpy, cheap, thin copper wire, for best results. If you don't have a good pair of jumper cables, use a quality battery charger to charge the battery for a few hours to see if it will then start. If you have neither, remove the battery (note which side the positive terminal is on before removal) and take it to your local auto parts store to have it tested. Most Kubota batteries will last about 7-10 years and then need to be replaced. Also, check the battery connections to ensure they are clean and tight. Check that all grounding cable connections are clean and tight. Many electrical problems can be traced back to poor connections.
While trying to start the engine, have the headlights on, and have a second person observe if the headlights dim when engaging the starter. If they do, then it is a battery that has lost its full charge. If they don't dim, start checking the connections from the battery terminals to the tractor's frame. Starter solenoids do go bad; however, more often, the battery itself or the connections from the battery to the engine are the culprits.

Low Battery voltage
Low Battery amperage
Bad cables or Cable connections (especially the ground connection).
Bad safety switches or wiring connections to or from said switches.

These are all things that it could be besides a bad relay.

Will try all you suggested, Thank for the Help

Thanks for the Help…

On my B1700 I got burned by a voltage drop across the safety switches. They all worked and ohm’d out properly but I was dropping around 4 volts across 3 switches which prevented the starter solenoid from engaging. Check you have 12V in to that solenoid. Installed a relay and no starting issues since.

Found the Issue of Tractor not starting a wire disconnected at starter solenoid, reconnected and tractor started right up… Thanks for all the help, got my green horn brain Thinking and bingo I found the issue… Thanks Again for the Help..

Couple years ago my Kubota starter relay died. Kubota wanted first-born male grandchild plus shipping for that relay.

Used a common automotive “cube” relay (they’re all rated 40A)…. at the ”jungle” …. 4 of ‘em …with leads….for $13. Installed one. That was years ago. Still works great. Still have 3 spares if it ever quits.

This was the issue with my G2160. Relay solved all the issues
