Additional Notes

  • The Kubota ST-30 front differential holds 4 liters of fluid, which is a service fill capacity indicating the amount needed during routine maintenance rather than a complete overhaul.
  • Under normal use conditions, the ST-30 front differential fluid is checked at 50-hour intervals, reflecting a relatively frequent inspection schedule typical of compact utility tractors operating under regular working loads.
  • The change interval for the ST-30 front differential fluid is set at 300 hours under normal use conditions, meaning a full drain and refill is required after every 300 hours of operation.
