Additional Notes

  • The Kubota ST-30 cooling system holds 3.9 liters of coolant, a figure that reflects the total volume of the sealed cooling circuit rather than a partial top-off quantity.
  • Under normal use conditions, the ST-30 cooling system calls for a fluid check interval of 10 hours, placing coolant inspection among the most frequent routine service tasks on the machine.
  • The coolant change interval for the ST-30 is set at 800 hours under normal use conditions, a relatively long drain period consistent with modern extended-life coolant formulations used in small utility tractors.
