How do you start a john deere x3043 mower. i have the key, put it in the ignition but nothing happened. is there something else i have to turn on? recently single...got the mower...

I would remove the PTO switch and have a Deere dealer test it. Also on the 500 series the PTO operates through the ignition control module which is under the dash, you can see it when you raise the hood. It is black and about 2" wide x 3" long and 1" thick.

check battery,fuses and connections --check safety switches --ignition switch and starter for power and connections

check the inline fuse by battery --test solenoid--test starter

check out all the safety switches , they make a circuit on closed , = make sure your safe not in gear etc , put a shunt direct and make sure you have cuircuit

I would start with either replacing the key switch, or tracing the wires to make sure they are not touching together somewhere, completing the ignition circuit.

you have a safty switch problem you have 4 to 6 switchs the easest way to test them ,startin with the seat get a ohms metter they are open or noramly closed

try bypassing the safety switches with a paper clip to see witch one is bad

The front mount mower has a safety switch on the park brake linkage and the seat belt linkage as well as on under the seat which is for the PTO,The one under the seat on the linkage just behind the battery is a culprit that needs adjusting to get the PTO to engage but it sounds like you need to deal with the seat switch circuit or replace the seat switch.

Sounds more like a bad starter than a bad coil.

A failing coil usually shows up during hot weather. The engine will start and run fine, then when it heats up, it just dies out. After a few minutes, it cranks again. Then the cycle repeats itself.

The ignition module and coil pack are the same part.

Are you sure full voltage is getting to the starter? There is likely a starter solenoid between the ignition key and the starter. These solenoids can be problematic and prevent the full 12 volts from getting to the battery.

you need to check the seat switch first then have the park brake switch looked at.is there power to the starter relay?
