7 Common Bad Boy Mower Belt Problems (Fixed)

Various types of problems can occur with Bad Boy mower belts. So, to solve the issue, finding the actual problem is inevitable.
So, here I will discuss the most common problems and their effective solutions:
1. Loose Bad Boy Belt
Over time the mower deck belt can stretch and wear. So, it can cause the belt to come off.
So, if you notice signs like cracking, stretching, or a glazed shiny appearance, the belt is either loose or worn.
Solution
Once you have found all these signs in your Bad Boy belt, it is better to replace the belt.
Otherwise, it may cause even more complications.
2. Shredded Belt
A shredded belt is another Bad Boy mower belt problem that occurs when the belt wears out and starts to shred.
The most common cause of a shredding belt is incorrect installation, worn-out pulleys, or improper tension. This problem also appears when it rubs in a displaced bracket.
Solution
Firstly, check out that your belt is installed perfectly. Then inspect for the shiny wear spot on your mower’s bracket.
If you find a spot, then consider replacing the bracket.
And if the problem remains after fixing these issues, you must replace the belt.
3. Debris In Pulley Groove
The pulley groove can become clogged with debris, which can cause inefficiency. It also elevates the chances of wear and tear.
When debris, such as grass clippings or twigs, gets stuck, it can prevent the belt from engaging properly. It will also lead to slippage or dislodgement.
Solution
First, turn off the mower and disconnect the spark plug to fix this problem.
Then, use a wire brush or compressed air to remove debris from the pulley groove. Be sure to wear gloves and safety glasses when doing this.

4. Grease Or Rust In Belt Deck
If the oil keeps dripping on the pulleys or the belt deck, it can dislodge the belt.
Moreover, if your pulleys or deck get rusty, they will dry. Resultantly, it will lead to the breaking of the belt.
Solution
The solution to this problem is to properly clean the oily and rusty parts.
Regularly lubricating the pulleys to prevent rust and ensure smooth belt operation is also a good idea.
If the problem persists, you should replace the belt.
5. Belt Tension Issue
Tension is imperative to prevent the belt from falling off. But if it exceeds a certain limit, it may decay parts of the deck.
On the other hand, if it is extremely low, it may cause the belt to pull off from the mower.
Solution
To avoid this, make sure to check the tension regularly. You can do this by pressing down on the belt with your fingers.
If it gives more than half an inch, it’s too loose. And if it doesn’t give at all, it’s too tight.
By using a belt tension gauge, you can conveniently adjust the tension. The range of tension for the belt of your Bad Boy mower is between 70-75 lbs.
You should also refer to your mower’s manual to find a suitable method for your particular model.
6. Poor Spindle Housing Bearings
The spindle housing is an important component of the mower’s cutting system. It holds the blade in place and ensures it rotates smoothly.
The spindle housing contains bearings that allow the blade to rotate. Over time, these bearings can become worn or damaged.
So, it can result in a loss of blade stability and reduced efficiency. If left unaddressed, this problem can lead to a complete failure of the spindle assembly.
Solution
To fix this issue, you should change the bearing of your mower. But some types of mowers don’t allow it.
So, you have to replace the complete cutter housing assembly.
7. Damaged Pulley Bearings
Damage pulley bearings are also another common belt problem. Each pulley needs to be flat on the Bad Boy mower deck.
Moreover, it should also be parallel to the deck of your mower. You should also ensure that there must not be too much movement.
Therefore, if the belt is operating on a pulley that is not leveled on the deck surface, it will come off after some time.
Solution
To solve this issue, you have to spin each pulley slowly with the help of your hand.
You must replace the pulley if you notice any resistance or noise from the bearing.
