LS Won't turn over

[Mely75]

Hello everyone, Thanks in advance for any tips, guidance or suggestions.

So I have a XJ2025H (hydrostatic) I was in the middle of tilling a garden bed, after a couple hours of tilling and spreading mulch I climbed off the tractor and within a couple seconds the tractor died and will not turn over. At the time the tractor died the PTO was not engaged and was in the neutral position.

Since then I have checked all fuses, including the 40amp slow break fuse and replaced them all with new. I've checked the PTO engagement switch, and the seat safety switch, both appear to be in good condition. I toggled the hydrostatic pedals to make sure they were resting in neutral and they are. The power panel on the dash illuminates, lights and blinkers work, As a last ditch effort I tried jumping off the tractor just in case it could have been the battery.

Any thoughts on what to diagnose next? I am at a loss with limited mechanical skill.

Have a few possible, but need more info. Bumping up for others.

You could bring the battery to an auto parts store and have it load tested. On mine, the only thing that would make the tractor do what yours is doing was the PTO switch at times. When it was young, you would have to snap it on /off a couple a times and there she would go. I'm not sure if the reverse switch is in the crank circuit or not but the seat switch isn't. Welcome to the TBN!

I have an L series Kubota. Although hydrostatic it has a clutch. I must depress the clutch in addition to satisfying all the other safety switches. Do YOU have a clutch?

Any clicking sounds when you try to start it?

I found a toggle relay that had broke on the hydrostatic arm that wasnt engaging and keeping it from turning over. Without the relay depressed it was sensing that the tractor was in gear and preventing it from turning over. Now it will attempt to turn over but wont continue to run, seems there is some issue with the fuel pump or a relay to the pump. Since it cranks now but wont stay running. II have checked the fuel filter, purge the fuel supply lines and I am getting fuel both on the supply and return side..........Fixed one issue to find another

How long have you had this machine? Engine hours?

You said 'I was in the middle of tilling a garden bed, after a couple hours of tilling and spreading mulch'. That doesn't sound like something that should break things the way mowing tall grass or brush might. Were you doing anything else prior?

Just for clarification.....it will turn over, start and run for a few seconds, but then dies. Is that correct?

 

[Mely75]

Thats right. As soon as you let off the starter it dies instantly
