have you disengaged the blades?

Customer: replied 11 months ago.
Customer: replied 11 months ago.
I've replaced the spark plug and have tried jumping the lawn mower with no success
Customer: replied 11 months ago.
My lawn mower is new this year. Battery even says may 2016 on it.
Customer: replied 11 months ago.
I had been mowing for about 45 min. I turned off the engine to move the trampoline and when I came back to the mower to turn it on the only thing I get is a clicking sound.
Customer: replied 11 months ago.
Anyone there?
Customer: replied 11 months ago.
Customer: replied 11 months ago.
I would like a refund. No help at all
Expert:  Curtis B. replied 11 months ago.

Where is the click coming from? Near starter or at the fuel solenoid when key is turned on?

Customer: replied 11 months ago.
Closer to the engine.
Customer: replied 11 months ago.
Under the seat
Expert:  Curtis B. replied 11 months ago.

With zero turn , one of you arm switched may be stuck, keeping starter from working. You say you tried to jump it and same thing? Ay of the safety switches, seat, and neutral switches will kill the start circuit.

Expert:  Curtis B. replied 11 months ago.

What is the model number ? Where is the starter solenoid, It will be at the end of the positive battery cable. Are the battery cables tight on the solenoid?

Customer: replied 11 months ago.
I get the clicking sound when I turn the key. I assumed that means safety switches are all working.
Expert:  Curtis B. replied 11 months ago.

Check the wires at the solenoid.

Expert:  Curtis B. replied 11 months ago.

Battery cables tight?

Customer: replied 11 months ago.
Wires look good. As I said it's a very new mower.
Customer: replied 11 months ago.
Battery cables secure
Customer: replied 11 months ago.
Model number 74723
Expert:  Curtis B. replied 11 months ago.

Can you jump the solenoid, from the battery cable terminal to the switch wire n the same solenoid and see if starter engages?

Customer: replied 11 months ago.
Jump the solenoid? I put the clamps directly on the solenoid bolts?
Customer: replied 11 months ago.
Bypassing the battery?
Expert:  Curtis B. replied 11 months ago.

No, just use a short wire to jump one terminal to the other.

Expert:  Curtis B. replied 11 months ago.

this tests the battery, cables, solenoid and starter

Customer: replied 11 months ago.
I can tell its passing a currant to the battery when I put my clamps on it
Expert:  Curtis B. replied 11 months ago.

I'm trying to get test results. Battery with bad cell can be jumped.

Customer: replied 11 months ago.
Do you have a picture of what you want me to do?
Expert:  Curtis B. replied 11 months ago.

no, battery cable goes direct to the starter solenoid, on the solenoid is the cable post, it also has a set of small terminals, you would jump with insulated wire from the cable connection, to the small post. This is same connection that key would make.

Customer: replied 11 months ago.
I don't have an insulated wire...what could I use?
Expert:  Curtis B. replied 11 months ago.

Screwdriver or other metal shafted tool.

Customer: replied 11 months ago.
It sparks
Expert:  Curtis B. replied 11 months ago.

?? You could use the probe end to connect the two posts. large cable to small terminal. If it sparks and does not turn engine, battery is weak, or bad, or the starter is bad, or engine does not turn. Can you turn the engine by hand using the screen on top?

Customer: replied 11 months ago.
It only sparks. Doesn't engage engine.
Expert:  Curtis B. replied 11 months ago.

No volt meter? Can you turn engine by hand? I suspect battery is dead.

Customer: replied 11 months ago.
Battery appears to be at 25-50%. I can charge it but I tried to jump it so I don't know that charging it will do the trick.
Customer: replied 11 months ago.
Where do I turn it by hand? Also, I had been mowing for 45 min before I stopped it for 2 min and the it never started again.
Customer: replied 11 months ago.
Battery fully charged. When I do try it a full charge or when i jump it there is more of a whine. Not the clicking sound.
Customer: replied 11 months ago.
then eventually goes back to the clicking sound.
Expert:  Curtis B. replied 11 months ago.

Remove spark plugs and see if the engine will spin. Whine from starter tells me starter is trying , but engine is too hard to turn. To turn manually you have to get to the flywheel, the rotating part on top. Usually there is a screen attached, and you can move it by hand. If not, screen cab be removed and a socket wrench used on the flywheel nut.

Customer: replied 11 months ago.
Spark plugs removed. Tried the ignition and got same results. Now will remove the screen to manually turn the flywheel
Expert:  Curtis B. replied 11 months ago.

ok.

Customer: replied 11 months ago.
Looks like there are two screens. I removed the top one. I can't turn the second one. Do I remove that one as well?
Customer: replied 11 months ago.
Sending a pic
Expert:  Curtis B. replied 11 months ago.

I can't see what you have, can you attach photo?

Expert:  Curtis B. replied 11 months ago.

Yes, the round one rotates with the flywheel . Remove it to expose the flywheel nut.

Customer: replied 11 months ago.
Ok. Give me a minute
Expert:  Curtis B. replied 11 months ago.

OK>

Customer: replied 11 months ago.
Flywheel doesn't seem to be moving.
Customer: replied 11 months ago.
Actually. I probably have to remove another layer to get to the flywheel
Customer: replied 11 months ago.
Is that right?
Expert:  Curtis B. replied 11 months ago.

If flywheel does not move with wrench, the engine may be locked! With round screen removed, flywheel nut should be exposed!

Customer: replied 11 months ago.
Flywheel nut is probably under this layer now correct?
Customer: replied 11 months ago.
See pic
Expert:  Curtis B. replied 11 months ago.

Yes, you can't turn the flywheel from here? Not good!

Customer: replied 11 months ago.
I was expecting a nut in the middle of the flywheel. Am I not supposed to go down one more layer? At the pic layer I cannot move it.
Expert:  Curtis B. replied 11 months ago.

The four bolts are holding the plastic fan down. With the bolts removed, the fan should come off. Exposing the nut!

Customer: replied 11 months ago.
The flywheel will not turn either direction.
Customer: replied 11 months ago.
Any ideas from here?
Expert:  Curtis B. replied 11 months ago.

Engine is locked up. Was it low on oil?

Customer: replied 11 months ago.
It's right in the middle of full and low.
Expert:  Curtis B. replied 11 months ago.

You may want to look under the engine , to be sure that the belts haven't com loose and locked the engine, but it seems to be internal failure in the engine. Is this Briggs or Kohler engine?

Customer: replied 11 months ago.
I've pulled and moved all the belts. Seem good. It's a Briggs motor
Expert:  Curtis B. replied 11 months ago.

So engine is locked! The only way to find out what has happened to engine is to disassemble it, starting with removing the cylinder heads. As it has internal failure.
