    Electric PTO kills engine on a JD 180

    All, I have just finished restoring my JD 180.. I still have the deck removed from the mower.. I have one issue...

    When I go to engage the mower PTO the engine shuts off. And not like it’s choking out the motor but more of just the ignition is shutting off.

    The previous owener had jumper wires in the neutral safety switch and also the seat switch.

    Any simple ideas before I start reading into the wiring?

    The PTO does move freely by hand and will turn for a split second before turning off.

    Chris

    Thanks chris

    It's usually the seat safety switch that causes that. Check the seat switch. It shouldn't be the neutral, it should be the seat. If it was the neutral it shouldn't start.

    You do have to be sitting on the seat to engage the PTO. So if you are trying it standing next to it, that won't work.

    I suppose it could be a loose connection on the PTO switch too. Usually the seat.

    Ok I will play around with that again tomorrow the switch has a jumper connected..

    The tractor will start without me in the seat.. and runs fine, but the moment I try the PTO it cuts out..

    I'm thinking PTO switch may be bad, or bad connections on switches. I've attached a wiring diagram

    I'm thinking PTO switch may be bad, or bad connections on switches. I've attached a wiring diagram. The green wire is the kill wire for the engine (@ignitor) which routes to one half of the PTO switch and on to the seat switch. If that check out then it's the key switch.

    Are you in the seat when you engage the PTO? That was not clear from your posts. You need to be in the seat to turn on the PTO, or the engine dies. Safety stuff. From the diagram bloodrunsgreen posted, the seat switch is only in play when the PTO switch is on.

    The previous owner has bypassed the switch, on the three wire he has a jumper on them..

    Pto Engine Kill

    You want the seat switch to simulate "On-Seat"... . By schematic, it would just be a matter of unplugging Safety Switch, IE no jumper required! (Unless I'm Missing something!) Is this a new Tractor for you? When did it start misbehaving? I've had 140's, 316, 317, and currently 3-318's! Any one, will start and run with driver "off seat"(as long as, Neutral Switch is satisfied, and PTO switch is off!) It's the PTO Switch that activates the Seat Circuit ! I'd revisit that schematic.......

    In your original post, you said
    The previous owener had jumper wires in the neutral safety switch and also the seat switch.
    I took that to mean that you had removed the jumpers. Sorry for the misunderstanding.

    The schematic that bloodrunsgreen posted should have what you need.

    Like Scotty370 said, unplug the connector to the seat safety switch. From the schematic, two of the wires need to stay connected for the low fuel sensor.

    Well made some progress this morning.

    I found some wires that have Been spliced, I think the previous owner burnt out the PTO switch..

    Anyways I found he had a PINK / Black wire running from the sensor under the carb. (Which I cant find anywhere) on the schematic where it should go. He had it running with the yellow from keyswitch Into the Yellow on the PTO switch..
