In-Depth Talk: Why Mower Blades Won’t Engage?

A tiresome feeling appears when the Bad Boy mower blades won’t engage and hinders in cutting the grasses. But, you won’t have to face this anymore.

The details of each reason for this trouble are provided in this segment along with their specific remedies.

Well, let me break them down for you.

Reason 1: Loose or Overstretched Deck Belt

A deck belt is the one that helps the Bad Boy mower blades to turn on and continue the actions. But, as the belt is used regularly along with the mower, problems are common to attack it.

It can wear out gradually and get scratched, too. Dust and debris are a quicker way to make it bad. Moreover, an overstretched one is also not good for the blades to engage.

Solution: Tighten or Switch to a New Belt

First, check for the tension of the deck belt and tighten it by maintaining the necessity. Also, purify it as a step ahead solution.

Now, see if any scratches are noticeable or not. If you find any, do not use it again. As it won’t be able to help the blades anymore, switch to a new deck belt.

Reason 2: Bad Condition of Bearings

Bearings are meant to be for the idler pulleys to be in their fixed position and not to move unnecessarily. Unfortunately, they can wear out, get scratches or become completely bad.

As a result, the pulleys don’t sit in their place and move frequently. The deck belt also slips for their movement and thus, the blades face difficulty in engaging.

Solution: Change the Bearings

A proper observation of the bearings can let you know how they are functioning. In case they are the root cause, changing them is the wise act for the blades.

Reason 3: Less Power from the Battery

The Bad Boy lawn mower blades receiving less power from the battery is a matter to be stressed. Without enough power, they can not engage at all.

When the battery’s chamber gets rust or dust or debris stuck there, it can be backbreaking for the terminals to flow power. Moreover, if the battery is at the stage of dying, it won’t provide much power.

Solution: Clean the Unit or Replace the Battery

Cleaning the unit of the battery can let you notice if it works after that. Be cautious to avoid metal or strong elements in purifying it.

In case it still doesn’t work as required, you should think of replacing the battery. In my opinion, go for it immediately.

Reason 4: Malfunctioning PTO Switch

A common reason is the PTO switch that is for letting the clutch receive the  power that comes from the battery. You can already guess what an important task it completes.

However, as it is an electric component, many things can attack it or barricade its regular function. Gradually, it starts to malfunction and generates weird noises. For that reason, the blades get no power to run as usual.

Solution: Get a New One

Examining the PTO switch will show if the functioning of it is alright or not. If not, get a new PTO switch that is suitable for your Bad Boy lawn mower blades.

Reason 5: Clutch Fails to Work

A clutch is for flowing the power to the mower blades from the engine so that they can move. But, when the clutch is out of duty or failing in functioning, the power flow stops.

Also, the cable of the clutch can get corroded or faulty that refuses to carry power. Without power, how can the blades even start?

Solution: Observe and Replace it

Observing the clutch and its action will drive you to the correct direction. Keep an eye on its cable, too.

You can clean its cable or check if it is working. Do not think twice in changing the clutch or the cable if they are found to be defective.

Reason 6: Fuse is Blown

Last but not the least, another electrical issue can come up when the fuse is in a blown condition. As it is for protecting the electric unit, it surely endures imbalanced or strong electricity.

However, as it gets blown, the power from the battery can not go through it. Thus, the blades get zero power to turn on.

Solution: Get a New Fuse

Getting a new fuse is the ultimate way to get rid of this. Make sure to match the size with the blown fuse to ensure compatibility with your Bad Boy lawn mower.

How Do You Engage the Blades on a Bad Boy Lawn Mower?
