My John Deere A105 riding lawn mower hums and then it will finally start just one time. Turn it off and it hums and will not start. I have changed the spark plug, gas filter, air filter, ignition switch, and solenoid switch, What is the problem?
Make a youtube video of it so we can see and hear what you are trying to describe.

Get some jumpers ( boosters to US )
Hook one to the + on the starter motor and the - to a good metal grounding place like the head .
Hook the +to the battery + then touch the - to the battery -
If the starter spins properly then remove the + lead and try again
Does not spin = bad ground lead or connections .

Starter des not spin with 2 jumpers = bad starter .
