  Ensure the tracks are not too loose or too tight. Loose tracks can decrease traction, while tight tracks can cause unnecessary wear. Adjust the tension as needed.
  
• Clean the Undercarriage
  Remove any dirt, mud, or snow buildup from the undercarriage. Frozen debris can obstruct the movement of the tracks and lead to performance issues. Keep the undercarriage clean and free of ice to ensure smooth operation.
  

• Check the Windshield and Glass
  Clean the windshield and ensure it’s free of cracks or damage. Cracks in the glass can worsen in cold weather and affect visibility. If the windshield is damaged, replace it before the winter season.
  
• Check the Lights and Markings
  Ensure the headlights, tail lights, and reflectors are functioning correctly. Proper lighting and visibility are crucial for safety, especially in low-light or snowy conditions.
