Mower sometimes will not start. Has new battery

Make sure your new battery is charged up first. New batteries will die sometimes. Make sure your cables are tight and clean and your starter could be at fault if all that work it won't turn over. Make sure your engine is not seized as well.

If the battery is below around 11.8 volts it never will charge. The charging systems on these mowers are made to "maintain" the charge. Check the battery, if below 11.8 volts charge the battery with a battery charger. Then see if the mower will maintain the level. If not, you may have a bad battery. Your local automotive store can check it for you.

Sometimes the batteries need charging when you get them.

your having a problem with the starter sylinoid i would almost bet

look where the wires go into the key switch,try jiggling them sometimes they short out.

ck all your connections for corrosion and tightness

many of these units use the starter motor as the generator to re-charge battery. check voltage regulator & wiring.

Often mowers come with batteries which simply do not have the cranking amps to do the job. Have someone look at your mower and see if your attery has the sufficient cranking amps.

Check your battery water level if it's not a sealed battery. Some small batteries require you to fill them with both acid and water, some with water only when new.

If that is not a issue then you are most likely running on your battery alone. You need to check your charging system. Check your battery voltage when the unit has not run for at least an half an hour. Then check it when it's running. The voltage should be higher. It should be 12.5 to 14vac. Lower means your alternator is not working or a fuse is blown in your charging system. Higher means your voltage regulator went bad and the higher voltage will cook your battery in time. The voltage regulator is usually in the alternator and can not be changed without replacing the alternator. Check your parts diagram. If it lists a voltage regulator then you are in luck.
