get a new battery
Check the battery if it is OK. Then check solenoid to see if it is engaging .Check if the power is getting to the starter if power is at starter the starter may have bad brushes or something is binding the starter ( dirt ,bad bearings, broken magnets or burnt wires ). Starter spins the drive gear is probably in need of replacement.
You need a new battery!
The starter solenoid/relay switch is going bad. Eventually, it will just click and not start.
you need a new batt.
Battery dead
if there is a single click when you turn the key i would lean toward a starter being bad if there is multiple rapid clicks then i would lean toward a battery
Not on a push mower that has no electric start. On a riding mower, yes there is an ignition key.
Sounds like a starter problem. you can have a garage test it for you. Or you can test it yourself. Have you tried to bump start it?
Dead battery or a bad connection to the battery.
sounds like the battery is dead, take the battery to a shop that can load test it
I would check your charging system. If you turn over your key and your starter just clicks, it is usually a low battery charge or your starter is out. I would suggest jumping off your vehicle and taking it to autozone and have them do a charging test for free.
if it does not turn over and no clicking noise but headlights on, check start fuse and relay if it doesnt turn over and clicks probable starter solenoid
It means your battery is dying
