How do I know if my riding mower is charging my battery?
You should see a noticeable increase in the overall voltage reading at the battery when the engine is running. Starting and running the engine draws voltage from the battery and, once the engine is running at full throttle, the charging system compensates by sending voltage back to the battery to charge it.
Can a riding lawn mower run without a battery?
Are Batteries Necessary for Riding Lawnmowers? Unfortunately, most riding lawnmowers need a battery in order to function correctly. Your lawnmower has many attributes that will not function unless your battery is in working condition.
Where is the stator located on a riding lawn mower?
The stator on a riding lawn mower keeps the battery charged. The stator on a riding mower is located on top of the engine below the flywheel. As the flywheel turns over the top of the stator, electricity is created and sent back to the battery to keep it charged sufficiently.
What causes a riding mower to not charge the battery?
If your mowers electrical system is not working properly, you may have a bad battery. … If the battery has gone bad, it may not recharge at all, or may lose its charge very quickly.

How do I know if my riding mower battery is bad?
Read the meter. If it has 12.7 DC volts or higher, the battery is good and something else is causing your starting problem. If the voltage reading is lower, the battery is discharged to some degree but may perk up after charging. If it reads 11.5 volts or lower, the battery is most likely sulfated and needs replacing.
Can you use a car battery on a riding lawn mower?
Re: Will I damage my lawn mower by using a car battery for its ignition? As long as you’re sure that the mower system is 12V (and the car battery is 12V!) the higher capacity of the car battery won’t harm the mower. Just make sure you get the + and – connections the right way round!
