Replacing the Cub Cadet Lawn Mower Batteries

If you’re looking to replace your lawn mower batteries, look no further! Here, we have a descriptive step-by-step guide on how to do precisely that.

Engage Brake

The first thing you must do is engage the brake on your tractor and remove the key from the ignition. This is to avoid any mistake, for example, accidentally restarting your lawn mower mid-change. Once you’ve removed your keys and have them securely in your grasp, disconnect the spark plug wires first. 

Check for Model Number

The next step is to tilt your seat forward and check under it for the model number. Once you have located the model, you will be able to understand exactly which battery you will need in order to get your lawn mower up and running again! The seat number will directly reference your battery’s individual part number. 

Remove the Nut

Now you will need to remove the nut connecting the black cable to the battery. Next, you will need to remove the protective cover from the positive battery terminal. You will need to use two wrenches to remove the nut connecting the red positive battery cable. One thing you will need to ensure is that there is no connection made between the positive terminal and any metal parts on your tractor. 

Remove Batteries

Once you remove the nut and ensure that there is no contact between the positive terminal and any metal parts, you will need to remove the battery. You will need to make sure you hold down and note the orientation of the battery.

Once all of this is done, you will need to install the new batteries. One of the main things you will need to make sure of is that the new battery is in the same orientation as the old one. Next, you will need to make sure the positive cable is appropriately connected to the positive terminal. After that, you will need to remove the protective cover and reattach the negative cable to the negative terminal.

Start Tractor

Reattach the spark plug wires and put your keys back into the ignition to start the tractor. This is done to ensure that the tractor is operating perfectly. It also confirms that the batteries are the right kind for your model. 

After every mulling season, ensure that your batteries are stored in a cool and dry place in order to ensure they operate the way they are expected to. Your battery should be charged using a 12-volt battery charger. Make sure to charge at a maximum rate of 10 amps, and refer to your charger manual for further instructions! By using the original parts of the Cub Cadet Lawn Mower, you are ensuring optimal performance of your tractor with professional-looking results.

When to Replace Batteries

If you can see the warning signs of when your Cub Cadet Lawn Mower needs a battery replacement, you will be able to see it coming and get the batteries you need before the problem of a dead lawn mower arises. Here are some of the warning signs.

Inability to Start Engine

If the Cub Cadet Lawn Mower batteries are dead, the tractor will have trouble starting. The batteries will not be able to properly power the engine in order for the tractor to work. The engine will either crank very slowly or not start at all. 

Improper Fluid Levels

One of the first things you need to do if you think your battery is dying or dead is to check the fluid levels in each of your tractor’s cells. If the cells in your battery don’t have enough fluid, chances are they’re about to die.

Low Voltage Readings

Doing a voltage test will let you know if your battery is dead. A healthy battery will read between 12.6 to 12.8 volts. If your battery is dead, the voltage meter will read 12.0 volts. These are some of the warning signs you can look out for when you’re wondering whether your battery is dead or you just need to replace another part of the Cub Cadet Lawn Mower.


Keeping your lawn mower battery charged is necessary in order for your Cub Cadet tractor to operate optimally and have the best performance. If you use batteries that aren’t original, chances are they will either die out faster or not allow your lawn mower to operate the way it should. It’s important to note the warning signs when looking for a battery shortage in case you need to go out and buy a new one. This will save time and ensure your Cub Cadet Lawn Mower is operational at all times for your lawn mowing needs. You will never need to let your lawn overgrow!
