Mower wont turnover at key switch

Stx38 JD riding mower Google Search This should help.

There probably several kill switched, on the PTO and another under the seat. For diagnostic purposes only the switches can be jumped with a wire to see which switch is bad. Once it is located remove it and replace it with a new one.

Make sure clutch switch or neutral switch if auto is making.

there is now power from the ignition switch to the sinal wire on the solenoid, may be a fuse, or a faulty ignition switch

check the safety switch on the brake/clutch pedal bypass it with a paper clip to test it

If you are jumping it thru the battery and it starts, then chances are that your battery needs replacement.

there is a safety switch under the mower the clutch pedal closes for starting
look for plug to be off or cut wires.
also the solinoid switch close to battery could be bad.


don't forget to rate me.
thanks.

Try using jumper cables and jumping from the positive battery post to the starter lug where the main cable hooks to the starter. If you don't have jumper cables find the solenoid on the inside of the right side panel. Pull the rubber caps off and jump that with an old screw driver if the engine turns and starts on either occasion it is the solenoid. Part # 192507 sells for about $15.00 at searspartsdirect.com

your igision mogulater is toast..that is what give power to your spark plugs.. check that

Make sure the control arms are all the way out, the brake is locked in the on position. There are safety switches on each control arm and one on the brake lever, also there is a safety switch on the seat...if either is faulty the mower will not key start.
