Additional Notes

  • The Kubota ST-ALFA 30 and ST-ALFA 35 share an identical cooling system capacity of 5.8 liters, which represents the total volume of coolant the system holds during a standard service fill.
  • A 10-hour check interval applies to both the ST-ALFA 30 and ST-ALFA 35 under normal use conditions, reflecting the relatively short inspection cycles typical of compact utility and agricultural equipment operating in demanding environments.
  • The coolant change interval for both configurations is set at 24 months under normal use, meaning the replacement schedule is time-based rather than tied to engine hours alone.
