2. Two-Speed Transmission Problems: Some users have experienced issues with the two-speed transmission not engaging properly. This may be due to worn linkages or a malfunctioning solenoid. Inspecting and replacing faulty components can restore proper function.
   
3. Uneven Movement or Steering Issues: If the machine veers to one side or exhibits uneven movement, it could be due to joystick calibration issues or hydraulic system imbalances. Checking the joystick linkages and ensuring proper hydraulic fluid levels can address these concerns.
   
4. Parking Brake Switch Malfunctions: A stuck parking brake switch can prevent the machine from moving. Inspecting the switch and solenoid for proper operation can resolve this issue.
