Hello, My name is Dane and I am going to assist you in solving your problem.
It is preferable to carge your battery with a charger, but yes, you can jump your mower battery. Just make sure that both your mower and the vehicle you are jumping it from both have 12 volt batteries. If you have to jump from a car battery, leave the car engine off while actually starting. Red + to + first, then Black – to – Disconnect in reverse order. I hope I’ve helped. If you found this information useful, please leave me some THUMBS UP as deserved. Thank you! Dane

How to Identify and Fix Common Gardening Problems ?

We provide a variety of viewpoints on how to identify and fix common gardening problems. Our sources include academic articles, blog posts, and personal essays from experienced gardeners :

You can also attempt to recover the battery by overcharging the fully charged battery using a low amp trickle charger. Charge the battery for 24 hours using a regulated current of 200mA (milliAmps). This will boost the battery`s terminal voltage to 2.50-2.66 volts per cell and raise the battery`s internal temperature.
There are several reasons a Craftsman lawnmower may turn over but not start, with the most common ones including the following: Lack of fuel. Dirty air filters. Electrical issues in the ignition system or the starter motor.
“If the battery refuses to start even after you`ve attempted jumping it, you`ll need to test the battery with a volt meter,” says Cunningham. “You may have to buy a new battery, or there may be another issue like a faulty starter, which will require service to fix.”
Check – All modern mowers run a 12-volt system, and it`s perfectly OK to jump-start from your car.
Can you jump start a 6 volt battery with a 12 volt battery? Yes you can. Just don`t put a 12v battery in a 6 volt car and expect everything to run as normal, you will fry just about everything in it.
A smart charger will recharge a lawn mower battery in hours. Adjust the voltage and amp settings if you`re charging a 6-volt lawn mower battery instead of a 12-volt one.
A new lawn battery should last between three and five years. In order to achieve that, however, it`s important to perform regular maintenance. Here are a few tips to help you get the longest life possible out of your battery.
Hook the positive cable to the positive terminal of the car battery. Then connect the other end of that cable to the positive terminal of the mower battery. Tom: Then connect the negative cable to the car battery`s negative terminal, and the other end to the frame of the mower.
One common reason why a car won`t jump start is because the battery is completely dead. If the battery is completely dead, it won`t have enough power to turn over the engine, even with a jump start. In this case, you`ll need to replace the battery to get your car running again.
If the engine starter motor turns over, the starter solenoid needs to be replaced. If the engine starter motor does not turn over once a jumper wire is connected to the two large lugs on the starter solenoid, replace the engine starter motor.
Disconnected, dirty or fouled spark plugs are common causes for engines that won`t start. For small engines, spark plugs typically need to be replaced every season or after 25 hours of use. You should also check to make sure the spark plug gap is set correctly.
Does a Lawn Mower Have a Battery? Riding lawn mowers use a battery to turn over the engine and power extra components such as headlights and electric clutches. Your mower also has its own charging system that recharges the battery when the engine is running.
Ten steps to jump start a car

Ensure both vehicles engines are switched off, remove the ignition keys and open their bonnets (or boot if the battery`s located there). Attach one end of the red jump lead to the positive terminal on the flat battery.

Note: If you use a key to start your lawn mower, snow blower or outdoor power equipment, the small engine includes an electrical charging system with a battery and alternator.
At proper charging voltage, the internal heat is never high enough to damage the battery, but at 12V, the internal heat can actually cause the electrolyte inside the battery to boil. This will run your battery dry and create a thermal runaway scenario, which is very dangerous.
Your 6 volt starter will also work with the 12 volt system, with the caveat that you want your engine to start up relatively quickly. That will prevent your starter from being engaged too long and overheating.
Allow the charger to power up the battery for up to eight hours. It should have a full charge by this time. If you notice that it`s still indicating a low status, it`s time to replace the battery.
The symptoms of your lawn mower battery going bad include the engine not starting, the mower producing clicking noises and a rotten egg smell, the battery losing charge faster than normal, the mower refusing to cut grass, and poor fluid levels.
One issue is loose cables where they connect to the battery posts. A loose connection makes a battery work harder, thereby draining it of power more quickly. Cleaning the posts and tightening the connections should renew the battery`s ability to hold a charge. A larger problem is a cracked battery case.
You can expect to get anywhere from six to ten years out of your riding mower, or longer with proper care and maintenance. Like most machines, riding lawn mower life varies depending on a number of factors including terrain, maintenance and upkeep, number of hours used, and more.
Your 12-volt lead acid lawn mower battery is expected to last up to about four years with proper care and regular maintenance. In order to achieve that, it is important to charge and store it properly.
Whether it`s time to replace the throttle cable that controls the choke on your Craftsman mower or when it`s simply come loose and needs to be reconnected, it`s important that you do it correctly. Without the proper hookup, the choke won`t open and close, making it impossible for you to use your mower.
A dirty carburetor is one of the most common causes for a lawn mower not being able to start after sitting unused for months or years at a time.
Electric start is a feature only found on lawnmowers with combustion engines, as it isn`t required for lawnmowers with electric motors, such as mains electric or cordless (battery) lawnmowers.

I have trouble starting a toro walk behind mower
ANSWER : All, I thought my carb was shot, so I replaced it. Still, start but no run (and had to use starting fluid). THEN!!! I noticed the spring to the “rev limiter” (just below and towards rear of carb) was not “tight”. The stupid bracket that holds the end of that spring had been bent down ~1/16″ and that caused all this heartache. CHECK YOUR REV LIMITER!!!

Lawn mower cranck but wont start…
ANSWER : Since you already checked for spark and air I would drain all the fuel out of it and check that fuel for water. Over time some lawn mowers end up with contaminated fuel. You can see the water sitting on the bottom of the fuel if you let it stand for a bit in a small plastic bowl.

Be sure to empty and dry out you fuel can as well. Especially if the mower stopped running right after a refuel. Which is a good sign your gas can is contaminated too.
