This allows fluid to bypass. Slipping means the transmission is failing. It may need professional repair. Do not ignore transmission slipping. Continued use can cause more damage. Check the transmission fluid for metal particles. Metal shavings indicate serious wear. This is a clear sign of trouble.
Drive Belt Issues
The drive belt connects engine power. It powers the transmission. A loose or worn belt causes problems. The mower will move slowly. It might even stop moving. Inspect the drive belt regularly. Look for cracks or fraying. A worn belt loses grip. It can slip on the pulleys. This reduces power delivery. Replace a damaged drive belt. Ensure the new belt is the correct size. Proper belt tension is crucial. A loose belt causes slipping. A too-tight belt can damage components.
