Why Does My Bad Boy Mower Keep Breaking Pump Belts?

Why Does My Bad Boy Mower Keep Breaking Pump Belts

If you’re a Bad Boy mower owner, you might have noticed that your lawn mower seems to go through belts quickly. You might be wondering why your mower keeps breaking belts. There are a few possible reasons for this:

Reason 01. Low-Quality Pump Belts

Mower pump belts come in different sizes and materials. Some belts are made of low-quality materials. Over time, the pump belts can become stretched or frayed, making them more likely to snap. They may not be able to handle the amount of torque exerted by the mower’s engine. So they may break prematurely.

Reason 02. Incorrect Pump Belt Tension:

Another common reason is that the belt tension is incorrect. If the pump belt is too loose, it can slip off the pulleys or entangle other mower parts. On the other hand, if the belt is too tight, it can put undue stress on the bearings and cause them to fail. So keep the belt tension correct before operating the mower.

Reason 03. Broken Pulley Bearings:

The Bad Boy mower belt keeps breaking because the pulley isn’t spinning freely. If the pulley is seized up or not spinning correctly, it will cause more friction on the belt, increasing wear and tear.

When the blades are always engaged, it can also put extra strain on the pump belt, causing it to break more frequently. Keep the pulley in good working order, and the blades are only engaged when mowing the lawn.

Reason 04. Sharp Edges or Rust on Pulleys:

The pulleys are made of metal, which creates sharp edges that catch on the belts. Its surface should also be smooth. If you have any sharp-edged on the pulleys, use sandpaper to smooth them out.

As time passes, the pulleys can develop burrs or nicks that can catch and tear the belt. Rust can build up on the pulleys, causing them to be misshapen and preventing the pump belt from tracking correctly.

Reason 05. Debris in Pulley Grooves:

The pulleys are located below the deck of the mower, so they are constantly exposed to dirt and grass clippings. They can become clogged with small stones and debris. These clippings can build up in the pulley grooves and cause the belts to slip or break.

Suppose the manufacturer does not recommend using grease or oil on the pulleys, which can also cause debris to build up and eventually lead to pump belt failure. To prevent this, clean the pulleys and belts regularly.

Lubricate the Belt and Clean any Debris:

Debris can build up on the belt and make it slip or become misaligned. The belt can dry out and crack if it is not properly lubricated. Clean any debris off the belt and keep it well-lubricated. It will help keep it in good condition and prevent slipping or misalignment issues.

The blades can quickly overheat and break without a properly functioning pump belt. Keeping the pump belt cool and well-maintained is essential to ensure that your mower performs at its best.

Can My Bad Boy Riding Mower Pump Belt Stretch?

Yes, your bad boy mower belt can and will stretch over time. If you drive your mower for a long time or are exposed to extreme temperatures, the pump belt will stretch. The drive belt is subject to a lot of stress as it turns the pulleys that power the cutting blades. It caused the belt to stretch and eventually break.

Belt slippage can also be caused by excessive heat, which can cause the belt to expand and lose its tension. Weather conditions can also cause the belt to stretch more easily, so it’s important to check and adjust the tension of the belt frequently.
