Lawn tractor

It is usual to experience the low charging of the lawn tractor battery. As a result, your lawn tractor may not start. It happens when you have not used your lawn tractor for a while and the battery becomes dead. This might be a big problem for you if you do not know how to charge it. Don’t worry! In this article, I will provide you stepwise procedure to charge your battery easily. I will also tell you when and how to replace your battery.

Let’s see how it is done:

Step 1: Shut Off the Switch of your Lawn Tractor

Before touching the battery of your lawn tractor, it is imperative to check that it is turned off. For maximum safety, it is must to avoid any risk of unwanted ignition.

To unplug your mower battery, follow these steps:

  • Do not use metal tools that can come into contact with the battery terminals at the same time. Only use the recommended equipment in your user manual.
  • Unplug the black power lug of your battery.
  • Unplug the red power lug from the battery.
  • Check that no liquid is leaking from the battery
  • Carefully remove the battery from the tractor.
  • Put the battery next to your riding mower.

Step 2: Check your Battery 

Now, you need to take the distilled water and fill the battery up to the indicated mark.

Bring a wire brush to clean the lugs of the battery. If they are covered with a kind of white powder, it is normal: it may be sulfate that can prevent electricity from passing. Rub the lugs with a wire brush to remove the layer of sulfate. If you do not have the brush, try sandpaper.

Now check the battery label for the voltage you need to transmit (around 12-15V).

Take a multimeter and connect it to the (+) and (-) terminals of your battery. If no or very little voltage is detected, your battery is likely to be dead. If you detect more than 1/5 of the voltage, you can recharge it because it is likely that it is simply discharged.

Step 3: Charge your Tractor Battery Mower

Take a charger that matches the type and voltage of your lawn tractor.

Next, connect the battery with the red cable on the (+) terminal and then the black cable clamp on the (-) terminal.

Finally, connect your battery charger to the mains supply and charge it for at least ten hours.

When charging is complete, first, disconnect the charger from the mains supply and then the two clips one after the other. Check the voltage one more time with the multimeter to make sure the load is complete.

Tip: Do not leave your battery charging in a confined area as the charge produces flammable gas (hydrogen) and a simple spark could ignite.

Step 4: Reconnect the Battery to your Lawn Tractor.

Put the plugs back on your battery.

Gently put the battery back in the mower.

First, connect the black lug (-) and then the red lug (+).

Replace the sealing plate if necessary and check that everything is in its place.

Take your lawn tractor, switch the ignition on and watch the performance of your mower. Do not hesitate to run it for a while to see if the battery is holding the charge or if it is no more usable.
