• Uneven Track Wear: Uneven track wear can be caused by improper track tension or misalignment. Check the track alignment and adjust tension as needed. If the problem persists, inspect the undercarriage components for damage.
  
• Overheating: If the engine or hydraulic system is overheating, check the cooling system for debris or leaks. Clean the radiator and ensure that the coolant level is sufficient.
