Additional Notes

  • The Iseki TX 1000, TX 1300, and TX 1500 — all F-series models spanning 1978-1992 — share an identical cooling system capacity of 4.2 liters, indicating a common engine cooling architecture across those three variants despite their different model designations.
  • The TX 2140F and TX 2160F carry a larger cooling system capacity of 4.8 liters, reflecting the greater thermal demands of their engines compared to the earlier TX 1000-1500 range.
  • The TXG23, TXG237, and TXG237F3 each hold 4.6 liters of coolant, a figure that falls between the 4.2-liter and 4.8-liter capacities found in the TX-series models.
  • Coolant change intervals for the TX 1000, TX 1300, and TX 1500 are set at 12 months under normal use conditions, with no hourly interval specified alongside the annual schedule.
  • The TX 2140F and TX 2160F introduce a dual-condition change interval of 400 hours or 12 months, whichever comes first. The addition of an hourly threshold reflects the operational patterns typical of tractors used in measured working hours rather than calendar time alone.
  • The TXG23, TXG237, and TXG237F3 include a 10-hour check interval in addition to the 12-month change schedule. A 10-hour check interval is characteristic of early break-in or frequent-inspection periods, ensuring coolant level and condition are monitored closely during initial or intensive operation.
  • The TXG237F3 is specifically associated with the Iseki E3112-B59 engine designation, tying the 4.6-liter cooling system capacity directly to that engine variant.
