The mower will not start, already check start, is good, changed battery, gas solenoid also new, safety switch on seat is good.

Is there a button to stop and start blades turning ? if so check that out its in the on postion it will not start .

ZTR mowers typically require the following safeties;

1. Steering arms out
2. Parking break ON
3. PTO - OFF
4. Seat occupied (may or may not be required)

Cycle all the safeties above. If still no crank try holding ignition switch in start position then try moving steering arm(s) in out, park break, PTO, and bounce on the seat. If still no crank, trace circuit from ignition switch "S" pole through all safety switches to starter solenoid with DMM or simple auto circuit tester.

I have checked my part listings, I do not see a fuel solenoid on this model tractor.
If it is equipped with a solenoid and to operate the mower you must "jump" the wiring, you probably have a safety switch malfunctioning.

there are 3 safety switches,clutch,deck and seat, Craftsman 247288810 Lawn Tractor Parts
take the cover off so u can access the coil,unhook the black wire from the coil,not spark plug cable,try to start it,if it starts then a safety switch is bad,if it doesnt,then jump the solenoid,if it starts then it is the seat or clutch switch,if you want to bypass safety switches,connect a switch to the ground and coil

ignition switch

bypass the safety switches to test them while looking for the bad one the clutch/brake is the most common one

Hello,
My name is Dane and I am going to assist you in solving your problem. However, I would ask that you do one check for me before we go to the seat switch procedure. Please find the starter solenoid on your mower. Make sure that the large cables coming from the battery and going to the starter are clean and tight. Make sure that your 1 (possibly 2) wires going from your switch to your solenoid are also clean and secure. Use a volt meter on DC volts, or a test light and check the small lead on the solenoid and make sure that when the parking brake is on and the Deck PTO is off, that you aren't getting 12VDC when the key switch is turned to the start position. If you have a 2-wire system, 1 of them is for ground only. 1 of the 2 wires should get 12VDC. If you get 12VDC at the small terminal of the solenoid, but no power to your starter, the solenoid is bad.

But you are probably correct that you have a problem with the seat safety switch on your lawn mower. The seat safety switch makes sure that if you are ever thrown from your mower, the engine will die.

You should check under the seat of your mower and locate a small square box with normally 2 wires connected to the end of it. While looking at the switch, press down on the back of your seat and make sure your seat is activating the switch. If not, you must get the switch correctly positioned so it makes contact and pushes the button. If you found nothing wrong there, go to the next step.

Make sure the 2 wires are connected and the wiring is in good shape. Disconnect the wires from the switch and make sure there isn't any corrosion on the terminals of the switch or the connector. After you have done this, reconnect the switch and try again to see if the mower will start.

If not, disconnect the switch again and place a jumper wire between the 2 prongs of the connector and tape them so they will not ground out on the frame. Start your mower and see if it operates correctly. If so, you have got a bad seat safety switch and it needs to be replaced. This was only a troubleshooting procedure. You should never operate a mower with this switch disconnected, because you could be seriously injured. Go buy a new switch and replace it. You will need the make, model and serial number of the mower in order to get parts.

There is a small chance that either your clutch/brake safety switch or your PTO safety switch could also be at fault. Normally they won't go bad, but will just get out of posistion so that when you activate the clutch/brake they won

Not all mowers are the same, but most have the same safety switches. It will not start with the mower deck on. You have to have your foot on the brake or clutch, some of them have to be in neutral. some you have to be sitting in the seat. Is the gas on? Is there any gas in it? Is the battery good? The solenoid on the starter? Tap it with a hammer on the bolt if you can. Check it out, hope this helps.

Check your seat, drive safety switches. Can you turn the engine with jumper cables attached to the starter? It won't start, but should turn over, one of your safety switches is not working.

is the safety switch good in the seat and also check the safety switch on the brake pedal, if these check out then move onto to the ignition switch to make sure you are getting power out of the terminal marked s for starter. Sometimes new parts are bad also to rule out a defective solenoid and starter you can use a jumper wire from the pos post on the battery to the small termnal on the solenoid marked s for switch if the engine turns over then your problem is somewhere between the switch and the solenoid
