B- In Now

First, we used the Bad Boy Magnum to test out the feature. It is one of the newer models; it has all the newer functions. After filling up with oil, we tried the mower for around 5 hours. Then in the panel, there was the B- In Now. It means you have to change the oil. Doing this keeps the engine fresh.

The feature was added as it keeps the engine efficient. So every five hours, the following code shows up. You have to change the oil if you see the code. Make sure to change it as soon as possible. It’s beneficial because it increases the longevity of the engine. Allowing you to use it for a longer time.

B- Air Now

Among some bad boy mower codes, sometimes you will notice the B- Air Now. It alerts you to inspect the air filter. When there is too much dirt or debris in the air filter, a code will repeatedly prompt in the panel. It’s better to check the air filter every day. Even the manufacturer recommends that you should inspect the air filter regularly.

We think that the feature is beneficial. Because it will let you know when to clean the air filters. It’s better to clean it rather than replace the entire filter. Furthermore, if you don’t keep the air filters clean, it can affect the fuel filters and the fuel pumps. For which your mower may not start in the future.

C – Belt

Mowers have various sets of belts inside them. They primarily work with the two gears, which directly affects the speed of the mowers. While misaligning the belt and starting the engine to check if the code had appeared, you can see the C- Belt code appear. So, this code usually shows up when the belts are not appropriately aligned.

To avoid such bad boy mowers troubleshooting issues, keep an eye out for the error codes. Using the mower while the belts are unaligned can cause further damage to it. They inspect the belts quickly if you see the code showing up.

R – Filter

The ‘R’ denotes replace/ change in the bad mower codes. Whenever you see the R before any codes, know that you have to replace that specific item. Usually, this code pops up if the air filter gets damaged beyond repair. So, if you see an R – Filter, change the air filters immediately.

Knowing this beforehand gives you a better advantage over your mower. It helps you to avoid further damage to any other parts. A faulty air filter can seriously affect the engine. This air filter prevents dirt and debris from getting inside the inner part of the mower. Furthermore, Kohler engines are of outstanding quality. Hence, it’s expensive to replace.

C – Grease

As you keep using your mower, various parts get a bit rusty. By rusty, we mean some essential components get a bit sticky. It’s bound to happen if you use your mower from time to time. When this happens, the mower gets a bit slower than usual. Moreover, the mower gives off a louder noise than you usually hear.

If you see the panel, you will find the C – Grease code appearing. It means your entire mower needs greasing. Well, it only appears after every 100 hours. Greasing the mower is the best solution. It keeps the bad boy mower running well.
