Kubota z724 zero turn

Hello folks, I’m new to the forum but I have this mower and I can start it and when I take my foot off the brake pedal pedal the engines cuts off, I spoke to my dealer about this and they suggested it could be either the seat switch or the brake switch so I installed new switches and it still cuts off when I take my foot off the brake pedal.

What about the switch(s) the that receive when the steering handles are in the neutral position?

With it running, brake set and the seat occupied pull one arm out. The engine should die. Repeat for the other arm. Engine should die. You’re testing for a faulty HST switch. If it stays running troubleshoot the faulty side.
The 50 hour start/opc test in the OM is a good troubleshooting check.

If the engine will crank, the control lever safety switches are good as they only have 2 wires to them.

We find a failed relay far more often than any switch.

That’s only true if the seat is occupied, brake on, both levers in neutral and PTO is off. Starting isn’t the issue, keeping it running is. Pulling out either lever with the brake on will kill the running engine.

I am very familiar with the operation and repair of these mowers, plus I have the WSM right here in front of me through the Kubota dealer portal.

Go ahead and instruct people to perform a bunch of useless checks.
Just make sure you tell the person what you are doing first.

Thanks for your response, so I did like you said on both sides and each time the mower cuts off.

Yes, I know your steer control lever safety switches are working, as the engine will crank.

Is your model number Z724XKW or Z724KH?
Is your serial number below 50001 or above?
There are at least 4 different wiring schematics for a 724 mower, and each is different.
